• Carbon Sequestration Potential in Rainfed Agriculture    Abstract    

  Rainfed agriculture is at the cross roads. With 82% of cropland area in the world and 60% in India, there is a strong need to enhance, improve and sustain agronomic productivity of rainfed agriculture. Soil degradation and desertification, severe problems in rainfed agriculture, are being exacerbated by the abrupt climate change (ACC), and are a positive feedback. These degradative processes can be reversed by enhancing the soil and ecosystem carbon (C) pools and increasing their mean residence time (MRT). Enhancing C pool in soils and biota necessitate adoption of sustainable land management (SLM) options. Important among these are mulch farming, cover cropping, integrated nutrient management (INM), including the use of compost and other biofertilizers. The goal is to create positive C, water, and nutrients budgets in soils under rainfed agriculture. Payments to farmers for providing ecosystem services, and creating another income stream by trading of C credits are important to promote the adoption of SLM options. In this context, there is a strong need to establish and strengthen mechanisms of communication between scientists on the one hand, and land managers and policy makers on the other. Basic laws of soil management must be observed so that soil, water and other natural resources are not taken for granted.

  Key words: Abrupt climate change, soil degradation, soil quality, mitigation and adaptation, sustainable agriculture, food security

• Growth Performance of Major Rainfed Crops in India    Abstract    

  This paper attempts to examine the performance of major rainfed crops in India during the last decade. The growth rates in area, production and yield were computed by fitting an exponential time trend equation for the period 1998-99 to 2008-09. The relative contribution of area and yield to the change in production (between TE 1998-99 and TE 2008-09) was examined by decomposing the total change in production into area effect, yield effect and interaction effect. Productivity of coarse cereals has significantly increased (30%) during the decade followed by oilseeds (13%). Growth in productivity of pulses (3%) is a bit stagnant in comparison to coarse cereals and oilseeds. Nevertheless the productivity of food grains excluding rice and wheat (coarse cereals + pulses) has recorded a rise of 20% during the decade, where as growth in productivity of wheat is as low as 9% and rice has shown 14% increase in its productivity. Coarse cereals, pulses and oilseeds together recorded 18% rise in productivity.

• Implementation of Contingency Crop Planning for Drought in Tribal Villages in Andhra Pradesh: Impacts on Food and Fodder Security and Livelihoods    Abstract    

  Dupahad cluster in Nalgonda district, in Andhra Pradesh, a predominant tribal inhabitation, suffered severe drought during 2009 kharif. Onset of monsoon was delayed by two months and the total amount of rainfall received was about 200 mm as against the normal of about 850 mm. This lead to wide spread distress among tribal farmers who, by and large, practice subsistence farming. To meet this adverse season, two drought tolerant and short duration crops (sorghum and horse gram) were introduced as a contingency measure. These crops were cultivated with minimum nutrient application and addition of organic manure (FYM). Timely implementation of contingency crop plan resulted in net profits to the extent of Rs. 20000/- per ha in sorghum and up to Rs. 16000/-per ha in horse gram. Besides the grain, crop residue obtained from these crops met the food and fodder requirements of tribal families while the villages in the neighbouring hamlets suffered due to drought. This paper outlines the methodology in executing contingency plan during drought and documents its impact on poor families in the nine tribal hamlets.

  Key words: Drought, degraded lands, crop contingency, livelihoods, tribal district.

• Economic Size of Water Harvesting Structures in High Rainfall Areas-An Optimization Approach    Abstract    

  Rainwater harvesting structures with supplementary irrigation increases the productivity of rabi crops which otherwise perform dismally under rainfed situation. In high rainfall areas, the size of water harvesting structures can not be determined on the basis of runoff yield from the catchment. Therefore, an optimization analysis was carried out with the help of net benefit from the definite set of crops i.e. potato, rajmah, wheat and rapeseed-mustard cultivated under different water management regimes for determining the size of water harvesting structures. The study indicated that the net benefit can be increased by providing one irrigation to the crops at their critical stages. The highest net benefit (Rs.38,200/ha) was obtained by growing irrigated rajmah at 100% area with one supplementary irrigation from a water harvesting structure having 950 m3 water spread over 5% area. The next profitable scenario was to cultivate at least 50% of irrigated potato and 25% irrigated rajmah. Rainfed rajmah (25%) was another crop picked up for higher net benefit. In this scenario, the net benefit was found to be Rs.25, 914/ha with a water spread area of 3.8% (712.5 m3). In the third scenario, where irrigated potato (40%), irrigated rajmah (25%), rainfed rajmah (25%) and rapeseed-mustard (10%) were cultivated, the net profit was Rs.24, 441/ha. The water spread area of the pond was 3.2% having total water volume of 617.5 m3.

• Drought Management Options for Rainfed Upland Rice in Eastern Uttar Pradesh    Abstract    

  A field experiment was conducted at Banaras Hindu University, Varanasi during Kharif season from 2000 to 2006 in order to characterize drought as well as relevant management practices for upland rice. It was observed that late season drought coinciding reproductive phase was most common while dry spells during early stages of the crop growth seldom occur. Mean yield data of seven years revealed that dry spells during early stages followed by light shower could be easily managed with an application of additional amount of 10 kg N/ha as topdressing resulting in maximum rice yield followed by straw mulching. However, one protective irrigation from harvested water was found significantly superior in enhancing grain yield of rice in the event of season drought.

• Assessment of Sustainability of Groundnut Yield using Rainfall, Soil Moisture and Soil Fertility Variables Under Arid Alfisols    Abstract    

  Permanent manurial trials have been conducted in a fixed site for 22 years during kharif 1985 to 2006 (July to November) to study the effects of rainfall, soil moisture and soil fertility on groundnut pod yield in a shallow arid alfisol at Anantapur. Nine fertilizer treatments with combinations of organic N through groundnut shells (GS) and farm yard manure (FYM) and inorganic N, P and K were applied every year. The treatments differed significantly from each other in all years except 1992, 1996, 2000, 2002 and 2006. Observations were recorded on rainfall received from sowing to harvest; soil moisture at 30, 60 and 90 days after sowing (DAS); and soil test values of organic carbon, P and K and used for modeling of yield over years. The treatments had a better sustainability in the range of 33.4 to 45.9% based on regression model of yield through soil fertility compared to 27.6 to 35.3% through rainfall; and 24.8 to 32.9% through soil moisture variables. 100% N (GS ~ 20 kg N/ha) + 50% NPK (10–20–20 kg/ha), 100% N (GS ~ 20 kg N/ha) and 50% N (FYM ~ 10 kg N/ha) were efficient based on mean, coefficient of variation and sustainability yield index. 100% N (GS ~ 20 kg N/ha) and 100% N (GS ~ 20 kg N/ha) + 50% NPK (10–20–20 kg/ha) were equally efficient, while 50% N (FYM ~ 10 kg N/ha) was the next best treatment for attaining sustainable groundnut yield under shallow arid alfisols.

• Crop Residue Management in Pigeonpea-based Intercropping Systems under Rainfed Conditions    Abstract    

  A field experiment was conducted during the rainy (kharif) seasons of 2005, 2006 and 2007 at Agricultural Research Station, Gulbarga, University of Agricultural Sciences; Dharwad (Karnataka) on shallow black soils to study the effect different crop residues in pigeonpea-based intercropping systems. The treatments comprised of two intercropping systems viz., pigeonpea + pearlmillet and pigeon pea + green gram with 12 different crop residues and fertilizer management. On the basis of 3 year results, pigeonpea + greengram intercropping system recorded significantly higher pigeonpea seed yield (12.11 q/ha), pigeonpea equivalent yield (14.15 q/ha), gross returns (Rs. 34,265/ha), net returns (Rs. 26,154/ha) and B: C ratio (3.21) over pigeonpea + pearlmillet intercropping system (11.37 q/ha, 12.75 q/ha, Rs. 30,616/ha, Rs. 22,667/ha and 2.84, respectively). The seed yield of pigeonpea, pearlmillet and green gram increased significantly due to combined application of crop residues and recommended dose of fertilizers as compared to control. Among the integrated crop residue management practices, application of pigeonpea stalks @ 5 t/ha + 100% RDF recorded significantly higher yield of pigeonpea (13.11 q/ha), pearlmillet (7.53 q/ha), greengram (3.82 q/ha), pigeonpea equivalent yield (15.25 q/ha), gross returns (Rs. 36,773/ha), net returns (Rs. 28,160/ha) and B:C ratio (3.26) over other integrated crop residue management practices, but it was found to be on par with application of sorghum stubbles @ 5 t/ha + 100% RDF, sunflower stalks @ 5 t/ha + 100% RDF and 100% pure RDF only.

• Response of Pearl Millet (Pennisetum glaucum) to Residual Fertility under Rainfed Conditions of Arid Region of Rajasthan    Abstract    

  A field experiment was conducted to asses the response of rainfed pearl millet to residual fertility in fenugreek-pearl millet cropping system when fenugreek was applied with different levels of phosphorus and zinc. Growth and yield characters namely plant dry matter, total tillers / plant, effective tiller / plant and test weight improved significantly by using residual fertility. During 2004, seed and biological yield and N, P, K and Zn uptake increased up to application of 60 kg P2O5 / ha whereas during 2005, response for these variables was obtained only up to 40 kg P2O5 / ha. Residual effect of Zn also enhanced performance of growth and yield characters and effective tillers / plant and length of ear increased up to 7.5 kg zinc / ha whereas, plant dry matter and total tillers / plant increased up to 5.0 kg zinc / ha. Seed and biological yield and harvest index also increased up to residual effect of 7.5 kg zinc / ha. Total uptake of N, P, K and Zn also increased significantly with the residual effect of Zn. However, foliar application of Zn to preceding crop did not have any effect on the succeeding pearl millet. Nutrient Use Efficiency (NUE) for both the nutrients decreased as the level of application of the nutrients increased.

  Key words: Growth, yield, nutrient uptake, pearl millet equivalent seed yield, Nutrient use efficiency

• Status of Farm Power Availability in the Selected Villages of Udhampur District (J&K State)    Abstract    

  A survey conducted in 40 villages of Udhampur District of Jammu region (J&K State) revealed that the mean farm power availability (kW/ha), draught animal density (ha/pair) and land holding (ha) sizes were 0.57, 1.55 and 1.07, respectively. The availability of human, draught animals and tractors was 1.47/ha, 0.65 pairs/ha and 1.32 per thousand ha of cultivable area, respectively. All the selected villages have farm power availability less than the National average i.e. 1.231 kW/ha. Eighty per cent of the villages have sufficient draught animals. It further revealed that the small (0-2 ha), semi medium (2-4 ha) and medium (4-10 ha) farmers constitute 90.86, 6.67 and 2.47 per cent and cultivates 69.62, 11.67 and 18.71 per cent of total cultivable areas, respectively. The study indicated a dire need of increasing the farm power availability, particularly in hilly rainfed areas for ensuring the timeliness and quality of operations to increase the productivity of land and to bring more area under cultivation.

• Long-Term Impact of Soil and Nutrient Management Practices on Soil Quality in Rainfed Alfisols at Anantapur in Andhra Pradesh    Abstract    

  Impact of long-term use of soil and nutrient management treatments was studied at All India Coordinated Research Project for Dryland agriculture Anantapur in three on-going experiments. In experiment 1, the long-term integrated nutrient management treatments tested under groundnut system significantly influenced most of the soil quality parameters. The soil quality indices as influenced by different integrated nutrient management practices varied from 1.32 to 1.96 across the management treatments. The key soil quality indicators identified under this system along with their percent contributions were: EC (7%), OC (17%), available N (4%), available K (16%), exchangeable Ca (16%), exchangeable Mg (16%), DTPA- Fe (6%), DTPA-Zn (2%), and dehydrogenase activity (DHA) (16%). In experiment 2 comprising of tillage practices and nutrient management treatments using groundnut as test crop, the soil quality indices varied from 2.01 to 2.7. The parameters which emerged as key soil quality indicators were: pH, EC, exchangeable Ca, Mg, DTPA- Fe, available B, DHA and labile carbon (LC). Of all the indicators, LC played a major role in influencing or aggrading the quality of the soils followed by soil pH. Among the tillage practices, low tillage played a significant role in improving the soil quality (SQI 2.43) and proved superior, followed by conventional tillage practice (SQI 2.37). Among the nutrient treatments, sole 100% organic treatment (SQI 2.62) proved quite superior in improving the soil quality followed by conjunctive nutrient application viz., 50% organic + 50% inorganic (SQI 2.35). While the sole 100% inorganic nutrient application could maintain SQI value only up to 2.10. In experiment 3, where groundnut-castor was the crop rotation, soil quality indices varied from 0.85 to 1.73 across the treatments. The key soil quality indicators identified for groundnut-castor system along with their percent contributions were: EC (23%), available P (21%), available S (22%), available B (9%), LC (21%) and MWD (4%). Application of 100% N (inorganic) maintained significantly highest soil quality with SQI value of 1.73, followed by application of 50% N through gliricidia loppings + 50% N through inorganic source (SQI 1.52). This observation clearly indicated the proportionally equal and important role-played by EC, available P, available S and LC in influencing the quality of these Alfisols under castor-groundnut rotation.

• Production Potential and Economics of Guinea Grass-Caribbean Stylo under Various Row Proportions and Fertility Levels in Rainfed Conditions    Abstract    

  A field experiment was conducted on sandy loam soil for four consecutive years (2003-04 to 2006-07) at Central Research Farm of Indian Grassland and Fodder Research Institute, Jhansi to study the effect of row ratios and fertility levels on growth, persistence of legume, productivity, quality and monetary return of Guinea grass-S. hamata intercropping system under rainfed conditions. Intercropping of Guinea grass with S. hamata in paired row produced significantly higher green forage (20.35 t/ha), dry forage (5.01 t/ha) and crude proteins yields (438.8 kg/ha) as compared to sole stand of both grass and legumes and alternate row and it was at par with 3:3 and 4:4 row ratios during all the four years. The dry matter yields of the recommended dose of fertilizer was reduced by 22.71 per cent over 75 per cent of RDF + 5 t FYM/ha. Persistence of S. hamata were higher (85.19, 74.72 and 69.78 per cent) in its sole stand when compared to alternate row of grass legume intercropping (76.26, 56.38 and 45.37 per cent) during all the three years. Intercropping of Guinea grass with S. hamata in all the row ratios resulted in land equivalent ratio greater than 1, indicating intercropping advantages. The maximum net returns (Rs 5103/ha) as well as net return/ Re invested (0.72) were obtained in paired row of grass-legume intercropping. Among fertility levels, highest net returns (Rs 5276 /ha) and net return/ Re invested (0.55) were achieved with application of 75% of the RDF in combination with 5 t FYM/ha.

• Quantitative Relationship of Root, Shoot and Spike Components in Rainfed and Irrigated Castor (Ricinus communis L.)    Abstract    

  A field study was conducted in castor (Ricinus communis L.) under Indo-US collaborative project during kharif season to assess the percentage reduction of root, shoot and spike components in castor under rainfed in relation to irrigated conditions. All the characters studied were grouped into three categories viz., those having i) low reduction (<5%); ii) moderate reduction (5-25%) and iii) high reduction (>25%). The results of the study indicated that all the phenological attributes, number of nodes, effective spike length (%) and oil content recorded a low reduction. All the primary spike components along with internodal length, stem height and diameter were found to have a moderate reduction. All the secondary and tertiary spike components along with the number of green leaves and total seed yield recorded a high reduction. All the root characters also registered a high reduction. The results revealed that the percentage reduction in yield was observed to be low in case of primaries as compared to the secondaries and tertiaries. Therefore, the emphasis on selection criteria should be made on the primary spike components in castor for improvement of moisture stress tolerance under rainfed conditions.

• Prediction of Chilli Yields based on Soil Nutrient Status under Rainfed Conditions of Dharwad District, Karnataka    Abstract    

  A study was undertaken to assess the nutrient status and yield of major rainfed chilli growing areas of Kundgol and Hubli taluks of Dharwad district, Karnataka. The analysis of soil samples from the selected chilli fields revealed that the soils were neutral to alkaline in reaction with normal electrical conductivity. Organic carbon content of soils was low to medium. Soils were low to medium in available nitrogen, medium to high in available phosphorus and high in available potassium status. Significant correlations were obtained between yield and applied nutrients, normalized difference vegetation index (NDVI) and leaf area index (LAI) of chilli crop in both the taluks. The multiple regression equations developed between yield and applied nutrients in terms of NPK, yield, NDVI and LAI also showed significant coefficient of determination in Kundgol (R2= 0.755 and R2 = 0.851) and Hubli taluks (R2= 0.874 and R2= 0.877).

• Information Needs and Production Constraints as Perceived by Extension Personnel towards Castor, Sunflower and Safflower Cultivation    Abstract    

  The information and communication technologies (ICTs) are capable reducing of the sense of isolation of the farmers and the rural community and provide open access to knowledge. I-kiosk is one of the important tools of ICTs, which can inform and educate the farmers about improved production technology and remunerative allied systems and components of agriculture. A project was initiated during 2007-08, to establish ikiosk at Directorate of Oilseeds Research (DOR), Hyderabad to serve the visitors including oilseed growers, with relevant information to suit their felt needs. As a pre-requisite, it is essential to assess the information needs of the extension personnel from the line departments, who have close contact with farmers. A total of 121 extension personnel representing 16 states and 62 districts of the country responded for the survey through structured questionnaire. The information needs as well as the perceived production constraints were prioritized based on the rank based quotient (RBQ) values. It was found that market related information, information about improved varieties and hybrids, integrated nutrient and pest management were the top felt information needs in castor, sunflower and safflower. Market related constraints, non-availability of quality seeds and damage due to pests and diseases were the top-ranked perceived production constraints of the extension personnel. These factors are to be considered while finalizing the content for the i-kiosk.

• Effects of Climate Change on Natural Control of Insect Pests    Abstract    

  Natural enemies of insects are likely to undergo diverse effects due to changes in atmospheric CO2 levels, increase in temperatures and shifts in precipitation. Plants respond to elevated levels of CO2 with higher biomass. As a result there would be a dilution effect on nitrogen levels and those chemical constituents that require nitrogen. Lower nutritional value of plants adversely impacts insects that feed on them directly and also their parasitoids and predators indirectly. Increased temperatures can alter both plant and herbivore phenology with likely impact on synchronization between the two again indirectly influencing the activity of natural enemies and the effectiveness of their natural control. Hymenopteran wasp parasitoids which are relatively host-specific are likely to be influenced more than tachnid flies which generally survive by feeding on a variety of insects. Higher minimum temperatures in temperate regions can lead to expansion of geographical range of insect pests which are currently intolerant to low temperatures. This may result in pest outbreaks in the newer areas if natural enemies fail to track and follow their hosts. Variability in rainfall reportedly has an adverse influence on parasitism levels of several caterpillar pests. Sucking pests like cereal aphids are less susceptible to climate change effects. In case of mealybugs, parasitism is reduced under conditions of water stress associated with drought conditions apparently due to improved immune response. The effects of climate change on natural enemies mediated by CO2, temperature and moisture effects on plants could be complex and unlikely to be predicted easily due to interactions between these effects. Adaptation and mitigation practices to combat climate change such as conservation agriculture practices are likely to have a positive effect on parasitoid and predator abundance with resultant benefits on natural pest control. Much of the climate change research has been conducted in the temperate countries. While referring to these available results, an attempt has been made in this review to illustrate examples of natural regulation of insect pests in India in the context of climate change and variability.

• Spill-over of Research and Development Priorities into New Millennium in Rainfed Rice Based Production System    Abstract    

  The rainfed rice ecosystem occupies 55% of total rice area but contributes 39% to production in India. The green revolution is observed to have a certain extent of stability in production apart increasing productivity. The rainfed rice ecosystem is broadly divided into upland, lowland and deepwater areas. The lowland system which includes both the medium lands and the lowlands in the topographic situations are of great relevance to enhance rice production in the country. Since a rainfed ecosystem entirely differs from irrigated ecosystem, where a crop is the base, the former is dependent upon several components for survival of the farmers ranging from crop to trees, livestock to aquatic animals in an integrated manner. Hence problems are multiple and wide ranging. The various issues covered are - priority rainfed rice districts based on secondary data, rainfed rice area and sustainability of yield in different agroecoregions (aer), rainwater management, drainage, cropping intensity, contingency plans, integrated plant nutrient management, indigenous interculturing in intermediate lowlands, management of weeds, pests and diseases, crop, tree and animal based diversification (olericulture, agro-forestry, dryland horticulture, livestock including large ruminants, small ruminants, pigs, birds etc (feeds and fodder, productivity, diseases etc.), post-harvest technology, and adoption of technology. Under these issues seventeen areas are identified to highlight state/ district, regional committee, agro-climatic region, and national scale. The high priority information of the districts is to be linked with zonal research station operated by state agriculture for preparation of research agenda. This forms basis for charting needs based on-farm participatory research and development in the target priority districts.

• Productivity Enhancement and Improved Livelihoods through Participatory Soil Fertility Management in Tribal Districts of Andhra Pradesh    Abstract    

  Under the National Agricultural Innovation Project (NAIP), three tribal-dominated districts (Adilabad, Khammam and Nalgonda) in Andhra Pradesh were selected to study the role of Site Specific Nutrient Management (SSNM) and balanced nutrition to enhancing income and livelihood security. By adopting a toposequence approach, 720 surface soil samples were collected from 39 villages with the participation of farmers. The soil sampling was based on stratified random sampling. Generally, it is believed that soils in the tribal region are rich in organic carbon and high in soil fertility because of relatively low intensity cropping. Contrary to this belief, the results of soil analyses showed that most of the soils are low to medium in organic carbon, low in available N and P, and low to high in available K. Among the secondary and micronutrients, S, B and Zn are the emerging nutritional constraints. By adopting SSNM and balanced nutrition approach, increase in yield ranged from 13 to 53% in cotton, 15 to 58% in chickpea, 18 to 44% in groundnut, 33 to 47% in green gram; and in vegetable crops, the increase in yield varied from 25 to 54% in tomato and 7-10% in Bhindi (Ladies finger) over the farmer’s practice (FP). Net income and return per Re investment also increased by balanced nutrition. In cotton, net income obtained ranged between Rs. 30783 and 55533 ha-1 in Adilabad, Rs.15, 030 and 70, 533 ha-1 in Khammam under balanced nutrient management. In other crops, the net return was Rs. 5564-14214 ha-1 in chickpea, Rs. 8380-13840 ha-1 in groundnut, Rs. 4207-8995 ha-1 in green gram, Rs. 47526-78329 ha-1 in tomato and Rs. 15570-38370 ha-1 in Bhindi under balanced nutrition. Mean value of return per Re investment was 2.97-3.05, 1.78, 1.60, 1.55, 2.09 1nd 1.78 in cotton, chickpea, groundnut, green gram, tomato and Bhindi, respectively under balanced nutrition.

• Effect of Fertigation with Sources and Levels of Fertilizer on Yield, Quality and Use Efficiency of Water and Fertilizer in Green Chilli (Capsicum annuum L., Chillies)    Abstract    

  Field experiments were conducted on red sandy loam soils of agronomy field unit, Main Research Station, University of Agricultural Sciences, Bengaluru during 2006 and 2007 to study the effect of fertigation with different sources and levels of fertilizer on quality, yield and use efficiency of water and fertilizers in green chillies. The experiment comprised of 12 treatments viz; four sources of fertilizers (urea, single superphosphate (SSP), muriate of potash (MOP); monoammonium phosphate(MAP), potassium nitrate (KNO3); Soil application of urea, single superphosphate, muriate of potash) and three levels of NPK (75, 100 and 125% Recommended NPK) in randomized complete block design with three replications. The recommended fertilizer dose for green chillies was 150:33:62.5 kg NPK/ha. Drip irrigation was given daily at 0.8 E Pan to all except treatments 10 to12 which received surface irrigation at 0.8E.Pan once in a week. Fertigation was done through Dosatron by feeding the required solution prepared as per the dose and source of fertilizer. All the fertigation treatments received 11 feedings at weekly interval. Observations on soil moisture, soil and leaf water potential, yield and quality were made. Water and fertilizer use efficiency and benefit cost ratio were worked out. The results revealed higher total soluble solids (4.13, 4.32 and 3.980 Brix respectably at 3rd, 6th and 9th harvest and significantly higher ascorbic acid content 142.31 mg/100g) in MAP, KNO3 fertigation at 125% recommended NPK and lower values were recorded with soil application of Urea, SSP and MOP at 75% Rec NPK. Similar trend was noticed with respect to fruit yield. (19.97/ha) and water use efficiency (WUE) (31:0 kg/ha mm). While fertilizer use efficiency (FUE) was higher with MAP, KNO3 fertigation at 75% recommended NPK (71.6 kg/kg NPK). The least WUE of 16.3 kg/ha mm was observed with soil application of urea, SSP, MOP at 75% recommended NPK. Similarly soil application of traditional fertilizers at 125% recommended NPK caused the lowest FUE of 35.3 kg/kg NPK.

  Key words: Fertigation, sources and levels of fertilizer; green chilli, fertilizer and water use efficiency.

• Climate change – Likely Effects on the Population Dynamics of Brinjal Shoot and Fruit Borer (Luecinodes orbonalis Guen.)    Abstract    

  A field experiment was conducted from 2002 to 2005 at the Regional Agricultural Research Station, Anakapalle for assessing the association between weather variables and brinjal shoot and fruit borer. Since the climate change projections for India indicate a change in temperature and rainfall, an attempt has been made here to study the impact of the likely changes in temperature on the shoot and fruit borer in brinjal. The results revealed that the per cent fruit borer incidence on brinjal had a positive correlation with maximum and minimum temperatures and also sunshine. Maximum relative humidity and rainfall had a negative correlation with fruit borer infestation. The brinjal borer infestation is likely to be influenced by maximum temperature. The prevalence of low temperatures can be expected to lengthen the life cycle of the pest and at elevated temperatures the pest is likely to complete the life cycle comparatively at a shorter duration and increase their population and thereby the incidence. At elevated temperatures, due to climatic change, the borer incidence in brinjal may rise slightly during summer but likely to decrease to a marginal extent during monsoon season.

  Key words: Climate change, Insect pests, Brinjal fruit borer, Leucinodes orbonalis and Pest-weather interactions.

• Effect of Sowing Time on Productivity and Economics of Different Kharif Crops in Scarce Rainfall Zone of Andhra Pradesh    Abstract    

  A field experiment was conducted during 2007-08 and 2008-09 at Agricultural Research Station, Anantapur of scarce rainfall zone of Andhra Pradesh to find out the most appropriate sowing time for different kharif crops under dryland situation. The studies revealed that the productivity was higher with first fortnight of June sown crops, whereas the mean productivity was significantly decreased with successive delay in sowing time. Groundnut yield equivalents were higher with June second fortnight sown crop (593 kg/ha) and was comparable with June first sown crop (585 kg/ha) and significantly superior than other three dates of sowing. Groundnut crop recorded highest pod yield (1023 kg/ha) followed by sorghum (914 kg/ha) and better than cluster bean and castor. Two years pooled data indicates that in groundnut, higher pod yield was recorded with July first FN sowing (1355 kg/ha) followed by June second FN sowing (1305 kg/ha), June first FN sowing (1174 kg/ha) and significantly superior than July second FN sowing and August first FN sowing. In sorghum, higher seed yield was recorded with August first FN sowing (1020kg/ha) and lower with second FN of June (817 kg/ha). In redgram\ (1188kg/ha) and cluster bean (569kg/ha) higher seed yield was recorded with first FN of June sowing and gradually decreases with successive delayed sowings. In castor, higher yield was recorded with second FN of June (707 kg/ha) followed by first FN of June (675 kg/ha). Groundnut, redgram and cluster bean crops recorded positive net returns in all dates of sowing tried. Rain water use efficiency was gradually decreased if the sowings delayed beyond July second fortnight. Results revealed that, for groundnut, July first FN is the most appropriate time for sowing whereas, for redgram , castor and cluster bean June month is the suitable time for sowing. August first FN is the optimum time to sow the sorghum under dryland Alfisols of Anantapur district.

• Response of India Mustard (Brassica juncea L.) Varieties to Sulphur Levels in Silty Loam Soil of Munger under Dryland Condition    Abstract    

  An experiment was conducted during three consecutive Rabi season from 2000-2003 at Regional Research Station Munger to study the response of Indian mustard varieties to sulphur levels in silty loam soil of Munger district of Bihar. Yield attributing characters did not differ significantly among mustard varieties except siliqua/plant. Grain yield recorded among Varuna and Kranti was at par and both produced significantly the higher grain yield than Pusa bold. However N, P, S uptake and content were significantly higher in Varuna than Pusa bold and Kranti. Application of sulphur recorded significantly higher yield attributes and seed yield than no sulphur. Among the sulphur levels application of 40 kg sulphur/ha though recorded maximum grain yield, Puptake and oil content but was found at par with 30 kg sulphur/ha and significantly higher than its lower levels. However N and S uptake increased significantly with successive increase in sulphur level up to 40 kg sulphur/ha. The optimum dose of sulphur for mustard varieties Varuna, Kranti and Pusa bold was computed to be 38.12, 46.37 and 34.47 kg sulphur/ha respectively. Multiple regression analysis showed that seeds/siliqua had highest contribution (49.62 %) to grain production.

• Castor (Ricinus communis l.) Based Intercropping System on Vertic Inceptisols under Rainfed Conditions    Abstract    

  A field experiment was carried out for two consecutive seasons of 2005-06 and 2006-07 at Regional Agricultural Research Station, Bijapur, Karnataka with an objective to find out the suitable intercrop for castor to obtain higher productivity and profitability per unit area per unit time by efficient utilization of natural resources on vertic inceptisol under rainfed conditions. There were thirteen treatments consisting of eight intercropping systems viz., castor with pearlmillet, seteria, sesamum, niger in 1:2 and 2:4 row proportions in additive series and five sole crops of the component crops involved in intercropping systems. The experiment was laid out in RBD with three replications. The mean results of 2 years revealed that, among the various intercrops tried with castor in 1:2 and 2:4 row proportions, castor noticed higher mean castor yield of 1291 and 1085 kg/ha with seteria and pearlmillet, respectively. Among the intercrops, pearlmillet recorded higher grain yield of 1398 and 1202 kg/ha at 1:2 and 2:4 row proportions, respectively as compared to other crops. The performance of various intercrops tested with castor crop excelled in 1:2 row proportions than in 2:4 row proportions. Castor equivalent yield was significantly higher with castor + pearlmillet in 1:2 and 2:4 row proportions (1678 and 1510 kg/ha, respectively). Similarly, intercropping of castor + pearlmillet in 1:2 and 2:4 row proportions was more remunerative with a net returns of Rs. 17,069 and Rs. 14,572/ha, respectively over other intercropping systems. The benefit cost ratio was also significantly higher with castor + pearlmillet in 1:2 and 2:4 row proportions (3.76 and 3.31) over sole castor (3.18) as well as other intercropping systems. Intercropping of castor + pearlmillet in 1:2 and 2:4 row proportions recorded significantly higher Land Equivalent Ratio (LER) of 1.80 and 1.56, respectively.

  Key words: Castor, intercrops, intercropping system, Vertic Inceptisol, Rainfed conditions.

• Performance and Stability of Cyamopsis Tetragonoloba (l.) Taub Genotypes under Rainfed Conditions    Abstract    

  Cluster bean (Cyamopsis tetragonoloba (L.) Taub) is a valuable arid legume grown in India, Pakistan and the United States. India accounts for 80% of its total production in the World of which Rajasthan occupies the largest area. Unavailability of promising drought tolerant varieties is responsible for its low productivity against the national average, which is a matter of serious concern. The performance and stability of 40 promising genotypes of cluster bean collected from different geographical areas were evaluated in rainy season consequently for three years under rainfed conditions. The combined analysis of variance showed highly significant genotype, environment, and genotype × environment effects on grain yield and seed gum contents. Stability analysis revealed 7 genotypes for superior seed yield and 8 for higher gum contents were stable across the environments. Eventually, two genotypes RGC 1076 and GAUG 004 with regression coefficient less than 1 and non-significant deviation from regression were fairly stable across the environments and had both mean seed yield and per cent gum contents above the grand mean. The genetic potential of RGC 1076 and GAUG 004 genotypes can be exploited in increasing production and productivity of cluster bean in drought prone areas of the country.

• Technical Feasibility and Economic Viability of Drip Irrigation and Polyethylene Mulch in Mango (Mangifera Indica)    Abstract    

  Field experiment was conducted on clay loam soil of Arjunpur, Khurda, Orissa to evaluate the effect of drip irrigation with black Low Density Poly Ethylene (LDPE) mulch at different levels of irrigation for mango. Out of eight treatments, six treatments were of drip irrigation with three levels of irrigation (V, 0.8V, 0.6V) and two treatments were of basin irrigation. The study indicated better growth and yield and prevention of fruit drop during summer months. The highest fruit yield 15.8t/ha was recorded under 80% irrigation through drip plus plastic mulch. However, comparative economics in the 5th year showed that 60% irrigation through drip and LDPE mulch gave maximum profit per mm of water used and highest water use efficiency. But maximum benefit cost ratio was observed in case of 80% irrigation through drip and plastic mulch.

• Effect of Integrated Nutrient Management on Yield, Quality, Nutrient Content and Uptake of Sweet Sorghum in Pongamia Based Agrisilviculture System    Abstract    

  Sweet sorghum (SSV-84) was grown under two year old Pongamia grafts in red sandy loam soil with different nutrient management options viz., application of FYM 10t ha-1, 100% RDF (80-60-40 NPK kg ha-1) alone and in conjunction with 75% RD N with 25% N through FYM, Poultry manure, Vermicompost, also with biofertilizers @ 5 kg ha-1 Azospirillum and VAM. Grain and stover yield of sweet sorghum was significantly affected by different treatments over control. Maximum grain and stover yield (30.78 and 92.25 q ha-1) was recorded by the 100% RDF (80-60-40 NPK kg ha-1) followed by integrated use of 75% RD N + 25 % N through Poultry manure (28.5 and 84.65 q ha-1) and lowest being control (18.38 and 48.88 q ha-1). Regarding quality parameters such as brix and sucrose content in green stalks influenced significantly among various nutrient sources in comparison to control. Among different combination treatments the highest brix content was recorded in conjoint use of 75% RD N + 25 % N through Poultry manure (12.14%) on par with 100% RDF (11.8%). In case of sucrose content the trend was in the following order 75% RD N + 25% N through poultry manure (9.86%) > 75% RD N + 25% N through vermicompost (9.29%) > 75% N through FYM (9.07%) > 100% RDF (8.85%). Pertaining to nutrient content, the integration of 75% RD N + 25% N through poultry manure was superior practice which resulted significantly higher N, P, K content in both grain and stover ((1.41, 0.319,0.46 and 1.36, 0.282, 2.68%) and uptake (58.86, 8.79, 12.53 and 38.90,7.78, 73.85 kg ha-1) respectively in comparison with 100% RDF.

• Factor Productivity and Yield Gap Analysis for Agricultural Production System in Northwest India    Abstract    

  Indo-Gangetic plains (IGP) region occupying a vast area over the states of Punjab, Haryana, Rajasthan, Uttar Pradesh, Madhya Pradesh, Bihar, and West Bengal in India is generally characterized by fertile soils, favourable climate and an abundant supply of water for agricultural production system. Agricultural factor productivity change indicates the sustainability and vulnerability of food security for the growing population. Analysis of factor productivity and yield gaps is needed for implication of policy formation regarding security of food system. This paper discusses factor productivity trends and yield gaps which are the keys to determine agricultural inputs use efficiency. Analysis of data revealed that the total factor productivity (TFPs) of rice, wheat, maize and mustard increased, although partial factor productivity (PFPs) of the crops for fertilizers and manures, irrigation and pesticides are in declining trend over the last decade in the Karnal district. The production can be increased by reducing yield gaps (attainable minus actual yields) viz. 48, 30, 35 and 52% for rice, wheat, maize and mustard, respectively.

  Key words: Factor productivity, yield gap, input use efficiency, Karnal district, IGP.

• Impact of Inter-terrace Conservation Measures on Rainwater Conservation, Runoff, Soil loss and Sorghum Yield on Vertisols under Dryland conditions of Semi Arid Tropics of South India    Abstract    

  Field experiments were conducted at the Research Farm of the Central Soil and Water Conservation Research Centre, Bellary, Karnataka during 2000-1 to 2002-03 in rabi season to study the impact of inter-terrace conservation measures on rain water conservation, runoff, soil loss, sorghum yield and soil properties. Decreased runoff and soil loss was observed in compartmental bunding + surface mulch treatment followed by graded border strips. Higher runoff and soil loss was recorded in control (up and down cultivation). Compartmental bunding + surface mulch and graded border strips increased the sorghum grain yield by 51.8 and 35.9% respectively, owing to reduction in runoff, soil loss and increased availability of moisture and nutrients, viz. N, P and K. Compartmental bunding + surface mulch and graded border strips recorded higher straw yield of 3043 kg ha-1 and 2868 kg ha-1 respectively. Soil moisture was conserved better in the top 60 cm in compartmental bunding + surface mulch. Higher moisture conserved with adoption of compartmental bunding + surface mulch resulted in higher values of yield components as compared to other treatments. Adoption of inter-terrace conservation measure, compartmental bunding + surface mulch reduced runoff and soil loss and improved the rainwater conservation, available nutrients, crop growth and yield.

  Key words: Compartmental bunding, mulch, moisture, nutrients, runoff, soil loss, sorghum.

• Evaluation of Watershed Development Programme under NWDPRA using Remote Sensing and GIS    Abstract    

  The evaluation and monitoring of watershed development programme is of prime importance to assess the conservation of natural resources and efficacy of its utilization. The conventional methods of watershed evaluation are cumbersome and time consuming. Moreover, they do not give synoptic view of the study area. Therefore, remote sensing and GIS is the appropriate tool for evaluating and monitoring the changes in the watershed due to development programme. We get repetivity as well as we can compare both, pre-and-post development situation of watershed for detection of changes. The study area was Sawarde Bk. Watershed (14/08/01 KR 69/2) of Kagal Taluk, Dist. Kolhapur during the period 1991-92 to 1995-96. The parameters used to study the impact of watershed development programme were land use, runoff and socio-economic status of the beneficiaries. The study revealed that the area under agriculture in the watershed increased after the launch of watershed development programme. The watershed development works have resulted in decrease in the runoff from the watershed and slight increase in water harvesting. On the socio-economic front, the literacy and the level of education of the people in the watershed has increased. The watershed development programme under NWDPRA created positive impact on agriculture and socio-economic condition.

  Key words: Evaluation, watershed development, remote sensing and GIS.

• Impact of Improved Dryland Technologies on Crop Yields in a Microwatershed in Southern Rajasthan    Abstract    

  Rainfed agriculture is the main source of livelihood for farmers in the southern region of Rajasthan. Farmers in the semi arid zone have normally very few options in terms of crop choice. Maize is the dominant crop in the region. Due to low and erratic rainfall , poor fertility of soils and non adoption of improved land , water and crop management practices, productivity levels of different crops in rainfed areas are not encouraging. On-farm trials/were conducted during 2002 to 2006 to validate important dryland agriculture technologies in comparison to traditional practices in village Pathliyas (Mangrope watershed). Overall increase in crop production by use of improved seed over local seed of different crops ranged from 17.4 to 133.7 per cent. Supplemental irrigation through harvested rainwater in maize + blackgram (2:2) and groundnut + sesame (6:2) intercropping systems is most promising for enhancing productivity and higher B: C ratio under rainfed conditions. Maize + blackgram intercropping (2:2) system gave highest net returns (Rs. 8640 ha-1) and B: C ratio (2.00) in comparison to sole and strip cropping of maize. Deep tillage + ridging 30 days after sowing + 100% recommended nitrogen through farm yard manure increased the grain yield of maize to the tune of 52.70 per cent as compared to farmer’s practice. Gram + mustard intrcropping (sowing of mustard across the gram at 4 m. interval) gave the highest net return (Rs. 22824/- ha-1) and B: C ratio (3.98) as compared to other methods of gram cultivation. Application of sulphur in groundnut was found beneficial and gave higher benefit-cost ratio (2.26) and net returns (Rs.11520 ha-1) as compared to control (1.88 and Rs. 7515 ha-1). Improved technology increased the productivity of kharif and rabi crops to the tune of 18.4 to 51.77 and 35.2 to 48.4 per cent, respectively over the traditional practice of the farmers. Improved bio-diverse farming system was found more profitable over the traditional system of maize cropping with higher net returns (Rs. 3141 ha-1) and B: C ratio (1.42).

  Key words: Operational research, improved dryland technologies, Rainfed, Maize based production system

• Effect of Inorganics and Organics on Soil Characteristics and Crop Yield under Rainfed Maize Gobi Sarson Sequence    Abstract    

  A field experiment on effect of inorganics and organics on soil characteristic and crop yield under rainfed Maize-Gobhi sarson sequence was conducted during 2006-07 and 2007-08 at research farm of Dryland Research Sub Station, Rakh Diansar to develop suitable integrated nutrient supply system for Maize-Gobi sarson sequence. Results indicated that integrated application of inorganics and organics influenced the grain and straw yield of Maize and Gobi sarson crops significantly over chemical fertilizer alone. The highest grain yield (35.6 q ha-1) and straw yield (106 q ha-1) of maize were recorded under the treatments which received 50% N,P,K through inorganics and 50% through organics (vermicompost) along with 25kg sulphur + 5kg zinc and 1kg boron per ha as compared to the yield of control plots (18.7 and 54.6 q ha-1). These values were at par with the application of farm yard manure. The residual effect of organics and S, Zn and B was also registered on succeeding gobhi sarson crop which produced 12.97 and 37.33 q ha-1 seed yield and straw yield respectively. The incorporation of organic sources of nutrients considerably improved the soil characteristics. The bulk density decreased with increase in organic carbon and available N, P, K status of soil, where as no remarkable change in soil pH and EC was recorded. The values of nutrient uptake by maize - gobi sarson crops also showed significant increase under integrated application of organics inorganics

• Statistical Modeling and Assessment of Effects of Rainfall and Fertilizer on Sustainable Soybean Productivity under Semi-Arid Vertisols    Abstract    

  An attempt is made in this paper to assess the fertilizer treatment effects on soybean yield under permanent manorial experiments conducted during 1999 to 2006 and select an efficient treatment for attaining sustainable yield in a semi-arid vertisol at Indore. The trials were conducted in maize, soybean and soybean + maize blocks with 12 treatment combinations of N through urea, compost and green leaf sources along with a common dose of P. 80 kg N + 60 kg P/ha gave a significantly higher mean soybean equivalent yield of 1927, 2297 and 1760 kg/ha with a yield increase of 67.0, 55.5 and 42.0% over control in maize, soybean + maize and soybean blocks respectively. The regression models indicated that June and September rainfall had a positive effect, while July and August rainfall had a negative effect on yield attained in maize and soybean + maize blocks. However, July and September rainfall had a positive effect compared to negative effect of June and August rainfall in soybean block. The yield had a better predictability of 0.56 (15 kg N (green leaf) + 10 kg N (urea)) to 0.78 (15 kg N (green leaf) + 20 kg N (urea)) in soybean + maize, followed by 0.42 (80 kg N + 60 kg P/ha and 15 kg N (compost) + 10 kg N/ha (green leaf)) to 0.61 (control) in maize and 0.15 (40 kg N + 30 kg P/ha) to 0.32 (25 kg N (compost) + 15 kg N (urea) + Azotobacter @ 2 kg/ha) in soybean block. 80 kg N + 60 kg P/ha had a maximum sustainable yield index of 45.0% in soybean + maize and 47.8% in soybean block, while 40 kg N + 30 kg P/ha had a maximum of 33.2% in maize block. Based on ranks assigned to treatments for yield and regression parameters, 80 kg N + 60 kg P/ha was superior in soybean + maize and soybean blocks, while 40 kg N + 30 kg P/ha was superior in maize block for attaining sustainable yield over years in a semi-arid vertisol.

• A Review on Decision Support System for Water Resource Development and Management    Abstract  

  The interactions of various components of water management systems are highly non-linear in nature. To develop the water resource utilization policy, huge and diversified data are required and then to use for the optimization which provide several scenario. These scenarios are further required to evaluate for the best solution. The Decision Support System (DSS) helps in selection of best solution among the feasible solution. Several DSS model has been developed in the past to assist in the selection of best solution. The present study reviews those efforts particularly in the field of water management. The present study deals with the historical development of Decision support systems. The components and characteristics of DSS and its successful implementation in agricultural system management and water resources development and management have been elaborated. The optimization methodologies employed in DSS are also been discussed. The study suggested that the DSS can be effectively used in solving the water management problem but careful selection and local calibration of the DSS are highly desired.

• Effect of Organic Management on Agronomic and Economic Performance of Sesame and on Soil Properties    Abstract  

  A field experiment was conducted during the rainy season of 2005-2009 to assess the yield and quality of sesame, and soil properties under organic vis-à-vis conventional production. During the initial three years, organic sesame yield was about 20% less compared to conventional farming. However, in the fourth and fifth year, the grain yield reduction under organic farming was 7.7 and 7%, respectively compared with conventional farming. However, the soil organic C, P, K, micronutrients, dehydrogenase activity and soil microbial biomass carbon were higher in the plots under farming. The incidence of major insect-pests and diseases were similar under both organic and conventional farming except that the pod borer incidence was high in organic sesame. The cost of cultivation of sesame was ` 10800 and 14050 ha-1 under conventional and organic farming, respectively. At least 40% price premium for organic sesame may be required to offset the higher cost of cultivation and low yields under organic production system compared with conventional production system particularly during initial years.

• Effect of Potassium Application and Moisture Conservation Practices on Yield of Cotton (Gossypium hirsutum)    Abstract  

  A field experiment was conducted to study the effect of potassium application and moisture conservation practices on yield of cotton (Gossypium hirsutum) at the farm of AICRP for Dryland Agriculture, Akola (Maharashtra). There were eight treatment combinations: two treatments on potash application i.e. potash application @ 20 kg ha-1 and no potash application, combined with four moisture conservation practices i.e. opening of furrow after every two rows, thinning 25 per cent plant population, crop residue mulch and combination of these three treatments. The experiment was laid out is a randomized block with two factors. The treatments were replicated three times. All the treatments were imposed in standing crop at 35 to 40 days after sowing of the crop, with the object of efficient management of available soil moisture during the monsoon break and/or post monsoon period as the crop duration left was about 70 to 80 days even after withdrawal of monsoon in this region. Pooled results revealed that the seed cotton yield due to potash application and no potash treatment could not reach the level of significance. However, the cultural practices significantly influenced the seed cotton yield. It was also observed that the seed cotton yield due to opening of furrow after every two rows of crop and spreading of crop residue mulch 35 to 40 days after sowing were statistically at par but significantly superior over thinning and combination of all the three practices. Results have clearly brought out that, for managing the soil moisture in the standing crop of cotton during the expected break in monsoon and during the remaining period of about 70 days crop after withdrawal of monsoon, the crop residue mulch should be spread or furrows should be opened after every two rows of cotton at 35 to 40 days after sowing.

• Mineral Profile of Feeds, Fodders and Blood Plasma of Dairy Animals in KVK Adopted villages of Ranga Reddy District in Andhra Pradesh    Abstract  

  A study was conducted to assess the mineral profile of feeds, fodders and blood plasma of dairy animals in KVK (Krishi Vignana Kendhra) adopted three villages (Tallaplli, Bobbiligam and Muddemguda) in Shabad mandal, Ranga Reddy district. Fifteen farmers from each village were randomly selected for collection of information on available feeds and fodder and feeding practices followed in cattle and buffaloes. Samples of green and dry fodder, concentrate ingredients, home made and commercial concentrate mixtures were collected randomly (n=15) from farmers in each village. Similarly blood samples from different categories of livestock were also collected. The dry and green fodders on average were deficient to excess in Ca, adequate in Mg, Co, optimum in Mn and excess in Fe content, while deficient in Cu and P. The dry roughages were deficient in Zn, while greens were adequate. The brans were rich in P, Fe, Mn and Co content, moderate in Cu, Zn and Mg. Concentration of Ca, P and Zn were low in blood plasma of grazing animals. Hence, there is a need to supplement specific mineral mixture to mitigate the deficiencies in dairy animals.

• Management of Drought through Crops and Varietal Diversification Under Dryland Areas of Western India    Abstract  

  The productivity of rainfed soil of maize ecosystem of western India is very low (< t ha-1) and unstable due to erratic monsoon and long dry spells, poor soils and several biological constraints (weeds, pest and disease). Keeping the urgent need for drought management in western India (85 Mha), crop and varietal diversification technology was generated through on-farm research trials in representative soils of western India after analyzing agroclimate (rainfall variability, probability of onset of effective monsoon and length of rainy season) and edaphic (soil water retention properties) constraints and prospects. Based on rainfall analysis, direct seeded, low water requiring crops namely, maize, sorghum, groundnut, sesame, clusterbean, blackgram, greengram and horsegram with their varieties were sown in medium textured soil during 2001-2004 with deep summer ploughing and cultivator during the pre-monsoon shower (May – June). Study revealed that in deficient rainfall years or drought years (2002 and 2003), when crop yield was affected adversely in medium textured soils, higher maize equivalent yield and water use efficiency were obtained from green gram variety K-851 (3934 kg ha-1 and 5.80 kg ha-1mm-1) followed by sesame variety RT-46 (3488 kg ha-1 and 5.27 kg ha-1mm-1) and groundnut variety TAG-24 (2935 kg ha-1 and 7.58 kg ha-1mm-1), respectively. Study also revealed that productivity of crops in the same soil did not fluctuate much between erratic rainfall (2001 and 2004) and rainfall deficit year (2003). The highest sustainable yield index (SYI) was recorded for greengram variety K- 851 (0.43), followed by sesame variety RT-46 (0.37) and groundnut variety TAG-24 (0.35) crops. Thus, crop varietal diversification technology was found to be very effective for drought management.

• Farmers’ Participation for Effective Utilization of Water Resources in Lift Irrigation Schemes in Rainfed Areas - Management Issues and Scope for Improvement    Abstract  

  Participation of water users’ association in the management of irrigation systems is considered essential, particularly in lift irrigation schemes which are crucial source of augmented water supply in rainfed areas. The present study was undertaken in Amarachinta and Kanuparthy lift irrigation schemes in the state of Andhra Pradesh with the aim of exploring the role of farmer’s participation in effective utilization of water resources in lift irrigation command areas and management issues. The study was based on the field data collected from the concerned government departments and farmers of these lift irrigation schemes, located in two different districts of Andhra Pradesh, India. Chosen parameters for assessing the impact of participation of farmers in the management include improvement in water use efficiencies (WUE), irrigation efficiency, project water efficiency, TFV, fee collection performance, sustainability factor of command area, fund flow and utilization etc. The increase in irrigation efficiency was from 46 to 81per cent. It was mainly due to the transfer of management from government to the beneficiary society in Kanuparthy LIS. These two LISs were successfully operated and maintained by beneficiary societies. The beneficiary societies of LISs were financially sound and ready to meet any contingency.

  Key words:Lift irrigation scheme, water use efficiency, command area, participatory irrigation management.

• Long-term Cropping, Fertilization and Manuring Effects on Carbon Pools, Carbon Sequestration and Yield Sustainability in Semiarid Tropical Conditions of Western India    Abstract  

  The impact of rainfed perlmillet-clusterbean-castor sequence, fertilization and manuring on crop yield, soil organic carbon (SOC) pools and SOC buildup was investigated in a long term fertility experiment carried out over 18 years under semiarid conditions. Conjunctive use of chemical fertilizer along with FYM could be used as a soil amendment to obtain higher yields, improved SOC pools as well as higher SOC buildup as compared to cropping without amendments. Higher mean seed yield of pearlmillet (809 kg ha-1), clusterbean (576 kg ha-1), castor (827 kg ha-1) over six cropping seasons were obtained as well as highest crop residues C (6.6 Mg ha-1) and total C (33.5 Mg ha-1) inputs were added 50% N (Fertilizer) + 50% N (FYM) treatment. Rainfall received during each month was positively correlated with the seed yield except for the month of September in case of pearlmillet and castor (R2 = 0.34 to 0.99; n=18). Highest SOC (2.7 g kg-1), total N (0.044%), MBC (135.5 μg g-1 soil) and POC (0.14%) were observed in in surface (0-0.2m) soil of 50% N (Fertilizer) + 50% N (FYM) treatment. These parameters decreased in lower depth. The amount of SOC build up was in proportion to the carbon (C) inputs (R2=0.93; P<0.05). Carbon pools such as microbial biomass carbon (MBC) and particulate organic carbon (POC) were significantly correlated (P<0.05) with SOC, which increased with organic amendments.

• Livelihood Opportunities in Drought Prone Bundelkhand: Lessons learnt from Garhkundar-Dabur Watershed    Abstract  

  Livelihood support options in rural India are limited. This leads to migration, unemployment, poverty and exploitation of rural people. Fortunately, in Bundelkhand region, Palas (Butea monosperma) naturally regenerates on wastelands, field bunds and extensively used as firewood, leaf mulch and for gum extraction. The species is a known host of lac insect (strain Rangmi). Therefore, attempts were made to introduce lac cultivation in the region which was successful but insect could not be perpetuated for regular inoculation. Gum extraction practice common in the region from B. monosperma is documented in this paper. Efforts were also made to derive livelihood for rural poor through institution building. Out of 4 SHGs constituted in study area, only one SHG could succeed in its endeavour. This, Maa Shitla SHG of Garhkundar constituted of 10 female members from S.C. community. During their journey from 2006-07 to till date, they have accrued assets and cash worth ` 74,000 plus. They meet regularly at weekly interval and contribute ` 10 each member, discuss business and maintain bank account. They are successfully running inter-personal loaning to meet group demand and enrich SHG, at affordable rate of interest. They started incense stick making as group activity but could not continue due to low returns. Further, they purchased one diesel pump to rent out which they disposed off after making small profit due to management difficulty. In the year 2008, when there was heavy downpour, the group and one individual attempted aquaculture in two check dams but incurred loss due to number of reasons and gave up the activity in subsequent years. In 2009, they started tent house business as group activity and successfully running and making profit out of it. They are strengthening the activity as part time livelihood support option on regular basis. This venture appears to be sustainable for this group because no such tent house facility is available in nearby villages. There is need to find out such viable ventures which can be promoted as livelihood support options in rural India where job opportunities are less.

• Nutrient content, Uptake, Soil Enzymatic Activity and Available Nutrient status of Sweet sorghum as influenced by Nutrient Management in Agri silvi culture system    Abstract  

  Sweet sorghum (SSV-84) was grown under two year old Pongamia grafts in red sandy loam soil with different nutrient management options viz., application of FYM 10 t ha-1,100% RDF (80-60-40 NPK kg ha-1) alone, and in conjunction with 75% RD N with 25% N through FYM, Poultry manure, Vermicompost; also with biofertilizers @ 5 kg ha-1 Azospirillum and VAM. Grain and stover yield of sweet sorghum was significantly affected by different treatments over control. Maximum grain and stover yield (30.78 and 92.25 q ha-1) was recorded by the 100% RDF (80-60-40 NPK kg ha-1) followed by integrated use of 75% RD N + 25 % N through Poultry manure (28.5 and 84.65 q ha-1) and lowest being control (18.38 and 48.88 q ha-1). Quality parameters such as brix and sucrose content in green stalks, influenced significantly among various nutrient sources in comparison to control. Among different combination treatments, the highest brix content was recorded in conjoint use of 75% RD N + 25 % N through Poultry manure (12.14%) on par with 100% RDF (11.8%). In case of sucrose content the trend was in the following order 75% RD N + 25% N through Poultry manure (9.86%) > 75% RD N + 25% N through Vermicompost (9.29%) > 75% N through FYM (9.07%) > 100% RDF (8.85%). Pertaining to nutrient content, the integration of 75% RD N + 25% N through poultry manure was superior practice which resulted in significantly higher N, P, K content in both grain and stover ((1.41, 0.319, 0.46 and 1.36, 0.282, 2.68%) and uptake (58.86, 8.79, 12.53 and 38.90, 7.78, 73.85 kg ha-1) respectively in comparison with 100% RDF.

• Soil Physical Properties of Vertisol Affected due to Different Tillage and Mulch Practices under Wheat (Triticum aestivum L.)    Abstract  

  A field experiment was carried out in rabi season during the year 2006-07 under All India Coordinated Research Project for Dryland Agriculture, College of Agriculture, Indore (Madhya Pradesh) to evaluate the changes in soil physical properties of Vertisol due to different tillage and mulch practices under irrigated wheat (Triticum aestivum L.). The experiment was laid out in split plot design with four main tillage treatments viz. T1: Conventional tillage, CT (Cross cultivation through cultivator); T2: Deep Tillage, DT (M.B. Plough); T3: Rotavator (RT); T4: Bed planting (BP) of wheat (three rows per bed), and the sub treatment comprises of two mulch treatments viz. M1: Soybean straw mulch (5 t ha-1) and M0: No –mulch with four replications. The water retention of these soils at 0.3 and 15 bar suction was 400 mm and 220 mm per meter of soil profile. Deep tillage gave 6.1%, 8.7% and 0.80% less bulk density of surface layer as compared to CT, RT and BP treatments, respectively. The lowest mean weight diameter (MWD) was recorded in case of DT (1.38 mm), followed by RT (2.28 mm), BP (2.56 mm) and maximum in case of CT (2.71 mm). Highest wheat yield was recorded with bed planting followed by deep tillage. The total root length under deep tillage was maximum, followed by bed planting, conventional tillage and minimum in case of rotavator till plots, mulch has helped in enhancing the water use efficiency of wheat by 21.62 percent as compared to non mulched treatment.

• Regional Approach to Enteric Methane Estimation from Dairy Animals:A Case Study of Semi-arid Region of Rajasthan    Abstract  

  Enteric methane emission accounts for about 17 per cent of national Green House Gas (GHG) emissions and 60 percent of the GHG emissions from agriculture sector in India. As the losses of methane represent inefficiencies and losses of energy in our current production system, it therefore stands to reason that estimates of enteric methane emission have long-run implications for environmental sustainability of dairy farming. The available literature is lacking in geographic region specific methane emission factor which varies based on quantity and quality of feed. Therefore, present study estimated the enteric methane emission from diary animals in semiarid eastern plain zone of Rajasthan using both primary as well as secondary data. The emission factor for each category of dairy animals was generated using the Tire-II approach proposed by Inter-governmental Panel on Climate Change based on primary data collected from 120 households of Jaipur district of the state selected purposively representing best case in the zone. The results of study showed that the methane factors for lactating local cow, crossbred cow and buffalo were 144.19g, 203.78g and 198.41g/head/day respectively, while dry local cow, crossbred cow and buffalo emitted 124.85g, 190.29g and 173.74g/head/day, respectively. The estimated methane emissions from enteric fermentation of dairy animals in the zone was 10308.37 thousand tones and more than 2/3rd of which was contributed by buffaloes. The methane emission in relation to milk production was worked out 75.72 g/kg of milk and reported highest in case of crossbred cattle (147.56g/kg milk). Study suggests for incorporating energy efficient diets such as concentrates and by-products of sugar industry, maintaining the livestock population in relation to carrying capacity, improving the productivity on animals, etc. for reducing the methane emission in the zone.

• Effect of Nitrogen, Phosphorus and Bio-Fertilizer inoculation on Growth, Productivity, Nutrient Uptake and Economic Returns in Fenugreek (Trigonella foenum-Graecum L)    Abstract  

  A field experiment was carried out at Sardarkrushinagar Dantewada Agricultural University (SDAU), during two consecutive winter seasons of 2006-07 and 2007-08 to study effect of nitrogen, phosphorus and biofertilizer on growth dynamics, productivity and nutrient uptake of fenugreek. The experiment consisting of sixteen treatment combinations with two levels each of nitrogen (N) (10 and 20 kg N/ha) and P2O5 (20 and 40 kg P2 O5/ha) and four levels of seed inoculation with bio-fertilizers (no seed inoculation (control), seed inoculation with Rhizobium alone, seed inoculation with phosphate solubilising bacteria (PSB) alone and seed inoculation with both Rhizobium + PSB) was laid in factorial randoblized block design (FRBD) with three replications. Application of 20 kg N and 40 kg P2 O5/ha significantly increased dry matter accumulation per plant (DMA), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) at all the growth stages as well as seed yield, straw yield, net return, benefit cost ratio (BCR) and, N, P and K uptake by crop over their respective lower levels. Inoculation of seed with both Rhizobium and PSB gave the highest DMA, CGR, RGR and NAR over their sole application as well as control. Seed and straw yield as well as, net return, BCR and, N, P and K uptake by crop was also recorded significantly higher with Rhizobium + PSB seed inoculation followed by Rhizobium alone. Thus, higher seed and straw yield as well as net return and BCR of fenugreek can be realised with the application of 20 kg N/ha, 40 kg P2O5 / ha and seed inoculation with Rhizobium and PSB both.

  Key words:Fenugreek, Growth dynamics, Nitrogen, Phosphorus, Rhizobium, PSB.

• Analysis of drought and dependable rainfall of Palamau Region of Jharkhand for better crop planning    Abstract  

  Daily rainfall data of fifty years (1958-2007) recorded at Zonal Research Station, Chianki were analyzed to study the drought characteristics and dependable rainfall of Palamau region of Jharkhand which is typical in climatic variability. The result clearly indicated that rainfall has been drastically reduced during last ten years where as, the frequency of drought years has been increased during last twenty years. There is also increase in total number of drought months and the drought frequency during September month which has increased by 250% in last 25 years in comparison to previous 25 years. This is a remarkable change because rainfed crops remain in flowering to grain formation stage and crops are adversely affected resulting in poor yield. The decrease in dependable annual rainfall has also been noticed during last twenty years. The seasonal dependable rainfall has also decreased in recent years. The sizable amount of dependable rainfall in the monsoon months i.e. June, July, August and September are crucial from agricultural point of view and has decreased during last ten years which may adversely affect crop yield. It has also been observed that monthly dependable rainfall of July and August in terms of amount has also been shifted. The dependable rainfall of October month also decreased during last ten years. Therefore, timely sowing of rabi crops is being affected, and without supplemental irrigation sowing has become difficult. Therefore, essentially, there is a need to harvest the surplus water during south west monsoon for life saving or supplemental irrigation and re-scheduling the sowing time and also to adopt new cropping system such as short duration Pigeonpea – chickpea, short duration rice – chickpea, maize/ sorghum / finger millet – chickpea, castor / cotton (unirrigated) etc which may be viable options in place of existing cropping system (rice-wheat, rice-fallow, etc.) of this region.

• Soil Health Issues in Rainfed Agriculture    Abstract  

  India would need to produce 350 Mt of food grains to feed the population of 1.41 billion by 2025. Contrary to ever increasing demand for food, the rate of response of crops to added fertilizers is declining year after year. The partial factor productivity of fertilizers decreased from 42 kg grain/kg NPK applied in 1975 to 18 in 1985, to 13 in 1995 and to 8 in 2010. The decline in rate of response of crops to added fertilizer under intensive cropping systems has possibly resulted from deterioration in physical, chemical and biological health of soils. Depletion of soil health in terms of soil organic carbon and available plant nutrients from dryland areas are some of the major threats to the soil productivity and land degradation. To meet the requirement of growing demand of food grains, it is imperative to increase the production potential through improving soil health in rainfed and dryland regions besides the irrigated regions. Balanced and integrated nutrient management was found to be viable technology to sustain higher crop productivity and maintain better soil health under rainfed as well as intensive agriculture systems. Improving soil organic carbon or arresting its depletion coupled with managing emerging multi-nutrient deficiencies are critical issues of dryland soil health. Integrated nutrient management improved the water movement in fine-textured soils while it reduced the water movement in coarse-textured soils through reduction in non-capillary porosity, thereby moderating both the adverse soil moisture conditions. Issues related to soil organic carbon and soil physical, chemical and biological health issues are highlighted along with policy interventions needed for soil health maintenance.

• Genetic Enhancement for Grain Mold Resistance and Grain Yield in White Pericarp Sorghum    Abstract  

  Sorghum is the fifth most important cereal crop grown in the world after wheat, maize, rice and barley. Grain mold, caused by several non-specialized fungi is an important biotic constraint of sorghum and it seriously compromises the yield and quality of grains obtainable from improved cultivars. This study was an attempt to demonstrate the feasibility of developing white pericarp grain mold resistant high grain yielding sorghum hybrids with stable performance over years. Of the 70 hybrids developed using grain mold resistant hybrid parents, 9 promising hybrids were identified and these along with their parents were tested during three rainy seasons (2006-08) for stability of grain mold resistance and grain yield at ICRISAT-Patancheru. From these, two hybrids (ICSA 101 × PVK 801 and ICSA 52 × ICSV 96105) with white pericarp, higher grain mold resistance and higher grain yield were identified that can be commercialized for food uses after testing for regional adaptation. The hybrid parents ICSB 400, ICSB 52, PVK 801, ICSR 89058, ICSR 91011 and IS 41675 identified in this study can be further used in developing hybrids with enhanced grain yield and grain mold resistance by crossing them with other parents with desirable agronomic traits and high adaptability.

• Assessment of Women Empowerment in Dairying: A Study of Semi-arid Rajasthan    Abstract  

  From time immemorial, women have played a pivotal role in our agriculture in general and dairy in particular. However, the role-played by women and their contribution to various economic activities in our country has yet to be given due importance. As women play predominant role in dairy farming, this enterprise can be sustainable from the social aspect if it is associated with empowerment of women. Therefore, the present study was conducted to measure the empowerment of women in Rajasthan. The study is based on primary data collected from Jaipur district of Rajasthan during 2006-07 for three seasons. The degree of empowerment was measured by using Empowerment Index calculated by Weighted Average Method by using 5 proxy variables. The results of study showed that more than 3/4th of females (78.33%) were engaged as main workers in dairying. The literacy status was found to be very low as only 34 percent adult females were literate in the study area. Nearly 2/3rd of the respondents were belonging to nuclear family while remaining 1/3rd were belonging to joint family. The decisions in domestic, financial and social matter related to dairying were mainly taken by male members of the family. The overall average Women Empowerment Index (WEI) was around 50 and varied in the range of 39.66 to 73.43 and low coefficient of variation of 13.59 percent. The mean WEI values across herd size categories showed very minor increase in the average index as herd size increased. The predominant number of women (97.50%) concentrated in moderate WEI range (range of scores middle 1/3rd). The study suggested for providing better education, particularly through adult education and ensuring access of resources to women.

• Effect of Green Manuring on Dryland Rabi Sorghum Productivity and Soil Quality in Vertisol    Abstract  

  A field experiment was conducted on Vertisol at Zonal Agricultural Research Station farm, Solapur during kharif and rabi seasons for the years 2005 - 2010 to study the influence of different green manuring crops and methods of application of manuring with chemical fertilizers on soil quality and productivity of dryland rabi sorghum in Vertisol. The experiment was laid out in factorial randomized block design with five green manuring crops in kharif viz Cowpea (Vigna unguiculata L.) and Amaranthus sp. (Amaranthus panicum) in-situ, while Takala (Cassia tora) @ 5t ha-1, Tarwad (Casia auriculata) @ 5t ha-1, Leucaena (Leucaena leucocephala) @ 5t ha-1 were brought from outside the field and were applied at flowering. Two methods of application viz. green manuring (in-situ) and application of green lopping followed by rabi sorghum with recommended dose of chemical fertilizers ( 50:25 kg ha-1 N:P2O5) were followed. Among the green manuring crops, kharif cowpea (in-situ) significantly increased the grain and stover yield, total N- uptake, MUE of grain, soil available nitrogen and organic carbon content of soil at harvest of rabi sorghum. The methods of application of manuring did not show significant differences except in MUE for grain, and organic carbon content of soil at harvest of rabi sorghum. The microbial populations of bacteria, fungi, actinomycetes, N fixer and P solublizers were highest at the time of sowing, and thereafter, decreased at flowering and harvesting stages due to moisture stress. The green manuring (in-situ) supported the better population of microbes than green lopping.

• Climatic variability and Productivity of Rainfed Groundnut in Middle Gujarat Agroclimatic Zone    Abstract  

  Nearly 80 per cent of the area under groundnut in India is rainfed and relies entirely on summer monsoon rainfall. An assessment on the impact of climatic variability on groundnut would provide basic information required for evaluating climatic potential of the region. Moisture deficit index derived from annual precipitation and potential evapotranspiration was used as a tool for identifying the climatic types in impact analysis on groundnut productivity in middle Gujarat. Majority of the years fell in the semi-arid category and the pod yields decreased with transition from humid to arid climatic conditions. Highly significant association (at 1%) was noticed between rainfall during 38thand 39th standard meteorological weeks and groundnut pod yield. Minimum temperature during early stages of pod filling (September 15th to 30th) was observed to significantly (at 5%) influence the groundnut yields. This study clearly depicts the influence of temporal variation in rainfall and temperature on the productivity of groundnut at Anand.

• Carbon Sequestration Potential of Oil Palm under Irrigated and Rainfed Conditions    Abstract  

  Terrestrial ecosystems play a vital role in regulating the abundance of carbon dioxide in the atmosphere. Plantations of trees and perennial crops like oil palm are an effective way of enhancing the buildup of the terrestrial carbon pool. The aim of this study is to quantify the potential of C sequestration in an adult oil palm plantations grown under irrigated and rainfed conditions in Andhra Pradesh. Total dry matter production in the systems was determined using non destructive sampling techniques and carbon contents estimated. The annual carbon sequestered by oil palm was 11.7 and 5.5 t ha-1 y-1 under irrigated and rainfed conditions, respectively for a 10-year-old plantation. The standing biomass of a ten year old oil palm plantation was of the order of 59.6 and 36.5 t ha-1 under irrigated and rainfed conditions. The results will also be significant in designing environmental policies for the country to deal with sequestration of greenhouse gases.

• Effect of Pruning on Productivity and Economics of Ber (Ziziphus mauritiana)-Based Hortipasture Systems    Abstract  

  An experiment was conducted during 2001-02 to 2004-05 on sandy loam soil to study the effect of pruning intensities on productivity and economics of ber based hortipasture systems under semi-arid rainfed conditions. Pruning of secondary branches of ber at 20 cm length from base recorded significantly higher dry forage (4.26 t/ha) and crude protein yield (319.9 kg/ha) of pasture as compared to pruning at 60 cm length (dry forage yield 3.77 t/ha and crude protein yield 280 kg/ha). However, dry leafy forage yield, fruit yield and fuel wood (4.11, 23.41 and 36.34 kg/ tree) were increased significantly when pruning of secondary branches were done at 60 cm length than 20 and 40 cm length . Among pasture combiations, intercropping of guinea grass with Stylosanthes hamata produced significantly higher dry forage (6.34 t/ha) and crude protein yield (455.3 kg/ha) compared to other grass-legume combinations. Dry leafy forage yield and fuel wood production of ber was not significantly influenced by different pasture combinations. However, significantly higher fruit yield (24.91 kg/ tree) was recorded under natural pasture than other grass- legume intercropping. Pruning of secondary branches of trees at 40 cm length from base recorded maximum net returns (` 40032/ ha) and net returns/ ` investment (2.14). Among pasture combinations, intercropping of guinea grass with S. hamata resulted in highest net returns (` 33693/ ha) from ber based hortipasture systems. However, maximum net returns/ ` investment (1.96) was achieved under natural pasture.

• Response of Azotobacter chroococcum in Pearlmillet under Dryland Farm Conditions    Abstract  

  The present investigation was undertaken to study the effect of seed inoculation with biofertilizers. Response of eight strains of Azotobacter chroococcum, one strain of Acetobacter diazotrophicus and one strain of Azospirillum lipoferum was studied on pearlmillet for four years under dryland conditions. Results indicated that seed inoculation with various strains did not improve the grain yield of pearlmillet significantly. However, numerical increase of 0.6 to 2.2 q/ha was observed over uninoculated control. Among various strains tested, A. chroococcum Mac 68 performed better during all the four years of experimentation as compared with other strains. Average increase in grain yield during four years with inoculation of strain Mac 68 was found to 17.9% over control. The reasons for better performance by strain Mac 68 can possibly be due to high nitrogenase activity, high level of siderophores and also due to production of growth promoting substances.

• Quality Traits in Rice under Three Different Water Regimes    Abstract  

  The present study was undertaken to study specific adaptability of 42 different rice genotypes under different water regimes and to understand the correlation between different yield and quality traits. The mean performance of genotypes under three sets of conditions indicated substantial differences in quality under rainfed and terminal stage drought (TSD) conditions as compared to the irrigated condition. High estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed for gel consistency, amylose, and water uptake and gelatinization temperature under all the three condition. Moderate estimates of genotypic coefficient of variation was observed for milling per cent, head rice recovery per cent, and moderate phenotypic coefficient of variation was observed for hulling per cent, brown rice length: breadth ratio, milled rice lenth: breadth ratio, elongation index and head rice recovery per cent. The highest heritability estimates (>70%) were observed for water uptake, gel consistency, amylose and HRR% under irrigated, for hulling%, milling%, gel consistency, amylose and head rice recovery (HRR %) under rainfed and for gelatinization temperature, gel consistency and amylose under terminal stage drought condition. Only kernel length after cooking showed correlation with head rice recovery in terminal stage drought (TSD) condition and elongation ratio and amylose were the two traits which exhibited correlation with head rice recovery under irrigated condition. Under irrigated condition 34 entries possessed long bold grains followed by 31 entries under rainfed and 33 entries under TSD condition. While, short bold grains were observed in 8 entries under irrigated, 11 entries under rainfed and 9 entries under terminal stage drought condition.

• Drought Analysis of Bellary Region in Karnataka    Abstract  

  Rainwater is the key input in dryland agriculture. The success to dryland agriculture lies in the efficient use of natural resources, particularly rainwater management. In a tropical country such as India which experiences more variation on rainfall, both in space and time, rain water management assumes vital importance in cutting down risks and optimizing crop production in dryland. Climate and soil are the two dominant factors in deciding whether or not runoff farming / water harvesting system will be possible and sensible. The hyper arid zone (P/PET < 0.03) is too dry for viable runoff farming, while sub humid zone (P/PET = 0.5 – 0.75) will be too wet. The runoff farming zone is primarily situated in the arid zone (P/PET= 0.03-0.2) and to some extent in the semi arid zone (P/PET = 0.2 – 0.5). Bellary region is characterized as one of the semi-arid zones of Karnataka bearing only 500 mm of average annual rainfall, confined in 35 rainy days having potential of runoff producing rain storms (5-7 days.) The study shows that the region experienced 13 meteorological droughts in the past 50 years in terms of annual rainfall. The region receives rainfall mostly from northeast monsoon and the crops are grown with conserved moisture during post rainy season (September - November). The seasonal rainfall analysis indicates the occurrence of agricultural droughts in 25 years in the past 50 years, which include 11 severe droughts. The average rainfall distribution shows that there is total failure in kharif season. However, some assured rainfall received during September and October has better prospect for rabi season. An attempt is made in this paper to analyze probability of rainfall, drought studies on various parameters and water budgeting studies etc. for designing of water harvesting system and crop planning. The findings of this study will help to plan the watershed management project in this region and similar agro climatic regions of Karnataka and A.P.

• Effect of Different Zn-Enriched Organics on Yields and Micronutrient uptake under Wheat-Maize (Fodder) Cropping Sequence in Semi-Arid Region of Gujarat    Abstract  

  Relative efficiency of different Zn-enriched organics in improving yields of wheat and maize as well as increase in fertilizer use efficiency was studied. The inorganic form of zinc was added @ 2.5 and 5.0 kg ha-1 through 500 kg of enriched organics viz., farmyard manure (FYM), poultry manure (PM), sewage sludge (SS) and biogas slurry (BGS). The Zn-enriched treatments of organics were evaluated as against straight Zn application @ 2.5 kg and 5.0 kg Zn ha-1 besides control. The application of Zn-enriched PM and BGS to wheat in rabi was found beneficial in increasing the yields of wheat as well as maize (fodder) in summer. The Zn-enriched PM and BGS improved average wheat grain yield by about 68 and 49 per cent respectively over control (1815 kg ha-1) whereas same was higher by 33 and 18 per cent over straight Zn application, respectively. The overall maximum improvement in maize dry matter due to residual effect of Zn-enriched PM and BGS was higher by about 19 and 9 per cent over straight Zn application. The Zn application in enriched form enhanced utilization of micronutrients (Fe, Zn, Mn and Cu) by wheat due to direct effect and by maize as residual effect of the treatments. The availability of micronutrients was also increased due to application of different enriched organics. The overall results of the study suggested that the Zn application through enriched organics could be a better way for management of micronutrient stress to increase crop yields as well as to reduce chemical load thereby helping in improving soil quality.

• A Regression Based Multi Parameter Soil and Water Quality Model for Maize yield prediction    Abstract  

  The ground water quality is the major contributing factor for sustainable crop production. But, routine chemical analysis of ground water and soil in a vast area is time consuming and integrated effect of soil and water quality on crop yield can not be obtained. Therefore, a study was conducted to characterize the ground water quality and its impact on soil characteristics and maize crop yield in Kothakunta watershed area at Wargal in Medak district of Andhra Pradesh, India. Based on the correlation studies between different water and soil quality parameters and crop yield, it was inferred that there was positive correlation between crop yield and pH of soil. It was negatively correlated with EC, RSC and Na. Hence, using multivariate statistical analysis, a multi parameter maize yield model was developed. The model quantified the relationship between independent variables (ECiw, RSCiw Naiw and pHsoil) and dependent variable crop yield (Y). The independent variables (soil quality parameters and water quality parameters) which are significantly affecting the yield were decided from the correlation matrix developed for water and soil quality parameters. The yield model was statistically significant (R2 = + 0.833) and can be used effectively to predict maize yield trend in the watershed.

• Productivity Response of Potato under Limited Irrigation Regime in Relation to Weather Parameters    Abstract  

  An experiment was conducted to study the response of potato under limited supplementary water supply in relation to rainfall and temperature with the treatments viz. T1: rainfed, T2: one irrigation at stolon formation, T3: one irrigation at tuber formation and T4: one irrigation at stolon formation+ one irrigation at tuber formation. The crop under T4 recorded the highest tuber yield in the first year but at par with T2. However higher yield was obtained under T2 in the 2nd year but not significantly different from T4. The yield was significantly higher than that in T3. This indicated that stolon formation is more critical than the tuber formation for soil moisture availability. The net benefit for the year 2007-08 was the highest for T2 followed by T1. The B:C was also the highest for T2. The experiment reaffirmed the need of water harvesting structure to increase the yield of potato over rainfed cultivation. Since the crop was cultivated under supplementary irrigation, the weather had significant effect on its performance. The rainfall occurred during planting, stolon formation and tuber formation had positive effect on the overall performance of the crop in both the years.

  Key words:Soil moisture, limited irrigation, potato, weather.

• Contribution of Nutrients through Critical Irrigation from Diverse Water Sources in Selected Watersheds of Semi-arid Tropical India    Abstract  

  Critical irrigation is one of the most important management options to protect the crop during weather aberrations like dry spells at critical stages of the crop growth in semi arid condition. Various water harvesting structures are useful in watershed areas to cope up with mid-season droughts. These structures provide critical irrigations at sensitive crop growth stages by which they supply essential nutrients to some extent. We estimated the contribution of various sources of water in terms of plant nutrients and to what extent critical irrigations meet nutrient requirements of various crops. By giving 4 cm irrigation, the maximum major nutrient (kg ha-1) addition in the studied watersheds is of the following order NO3 (5.2, Kothapalli); SO4 (15.2, Kolar); Na (72.0, Haveri); K (3.6, Govardhanapura); Ca (38.5, Semli and Shyamapura); Mg (20.5, Kothapalli) and for micronutrients (g ha-1) Fe (109, Kolar); Zn (40, Kothapalli); Mn (90, Kolar); Cu (120, ICRISAT) and B (190, ICRISAT). Percentage of recommended dose of nutrients which can be met by three irrigations in cereal crops (5-10, 15-100, 10-20% in N,S,K respectively); legumes (5-30,10-100, 5-10% of N,S,K respectively); cotton (10-15, 25-30, 5-10% of N,S,K, respectively) and micronutrients such as Fe, Zn, Mn, Cu and B to the full extent. With the number of critical irrigations increased, application of secondary and micro nutrients should be avoided which otherwise leads to higher cost of alleviation and environmental pollution.

• Integrated Weed Management in Maize (Zea mays) under Rainfed Conditions    Abstract  

  A field experiment was conducted during rainy (Kharif) season of 2005 and 2006 at Agronomy Research farm, Kumarganj, Faizabad, Uttar Pradesh to study the effect of weed management on weeds and yield of maize under rainfed condition. None of the pre-emergence herbicides alone provided desired control of weeds. However, inclusion of one hand weeding at 30 DAS with pre-emergence herbicides markedly improved weed control efficiency (WCE), yield attributes, grain and stover yield, nitrogen uptake and soil moisture retention. Two hand weedings at 20 and 40 DAS proved most effective in controlling weeds (WCE 66.2%) followed by alachlor @ 2.0 kg a.i./ ha + HW at 30 DAS. Significantly highest grain and stover yield, nitrogen uptake and protein yield were recorded under weed free treatment followed by two hand weedings at 20 and 40 DAS and alachlor @ 2.0 kg a.i./ha + HW at 30 DAS. Lowest moisture depletion was recorded under weed free treatment followed by two hand weedings at 20 and 40 DAS. The total water use from root zone was not affected significantly by different weed management practices.

• Effect of Cropping System on Runoff, Soil Loss and Crop Productivity    Abstract  

  A trial was conducted at All India Coordinated Research Project, OUAT, Phulbani during 2003-05 (3 years) with the objectives to quantify runoff and soil loss under different cropping systems and to develop relationship among them. Intercropping of groundnut with pigeon pea planted along contour gave highest rice equivalent yield (41.33 q ha-1), lowest soil loss (4.01 t ha-1) and lowest runoff of 207.21 mm (16.34 % of rainfall) followed by pigeon pea and groundnut strip cropping planted along the contour with rice equivalent yield of 36.93 q ha-1. Cultivated fallow gave the highest soil loss (8.795 t ha-1) and highest runoff of 328.29 mm (26.36 % of rainfall). The soil moisture content was low i.e. 9.9% and 9.8% in cultivated fallow (T9) and uncultivated fallow (T8), respectively. Thus, it can be concluded that intercropping of groundnut with pigeon pea planted along contour may be practiced to increase crop yield and lowering the soil loss and runoff in the hilly tribal areas of Kandhamal district.

• Effect of Storage on Chemical Parameters of Dehydrated Ber (Zizyphus mauritiana Lamk.)    Abstract  

  A study was conducted to assess the effect of storage on chemical parameters of dehydrated ber prepared by various treatments and drying methods. Dehydrated ber was prepared by subjecting the ber fruit to different pretreatments viz. blanching in boiling water for six minutes to check enzyme activity followed by one per cent potassium meta-bisulphite (KMS) dip for five minutes, sulphur fumigation for two hours @ 3.5 g kg-1 fruit and then drying by sun and oven methods. Moisture content of dried ber was maintained at about 14 per cent. The product was analyzed at an interval of two months upto six months of storage. An increasing trend was observed in reducing sugar, total sugar, tannin and ash whereas moisture and acidity showed a decreasing trend. After six months of storage, on the basis of sensory evaluation in oven dried method, no preservative + sulphur treated fruit (7.27) was found to be the best followed by no preservative + potassium meta-bisulphite (KMS) treated fruit (7.03).

• Economic Viability of Multitier Cropping System for Intensive Rainfed Farming in Eastern Ghat Highland Zone of Odisha    Abstract  

  A field experiment was conducted at Central Soil and Water Conservation Research and Training Institute (CSWCRTI), Research Center in Koraput district of Odisha (2007–2010). The experiment had treatments consisting of the combinations of fruit tree papaya (Carica papaya) and drumstick (Moringa oleifera) with boundary plantation of forest shrub i.e. Gliricidia sepium with its green leaf manuring to plots. Four crop combinations (ginger + pigeonpea (8:2), runner bean+ pigeonpea (8:2), ragi+ pigeonpea (6:2) and pure ragi broadcasting) were tested on 2 percent slope. The treatments were set split plot design replicated thrice. Periodical pruning of the boundary hedge Gliricidia and its manuring in plots significantly influenced no. of fruits tree-1 by 14.3 and 13.4 percent; average fruit wt. by 14.3 and 13.4 percent and yield tree-1 year-1 by 15.6 and 13.5 in papaya and drumstick, respectively. Papaya and drumstick trees raised in ginger: pigeonpea (8:2) intercropping system significantly improved their yield by 68 and 9.4 percent in comparison to ragi broadcasted plots. Among tested intercrop combinations maximum yield of 11.83 was recorded for ginger + pigeonpea (8:2) which is significantly higher to other intercrop ratios. Among four tested crop combinations ginger + pigeonpea (8:2) recorded the maximum pigeonpea equivalent yield of 11.83 qha-1. Among 24 tested systems ragi: pigeonpea (6:2) intercropping in drumstick based multitier system gave maximum BCR values of 3.15 with Gliricidia and 2.92 without Gliricidia, respectively. Less than 1 value of B: C ratio in ragi broadcasting indicates total loss to farmers. This paper proposes different multitier cropping models that for intensive rainfed farming area of eastern ghat highland zone large, medium and small farmer can adopt suitable multitier cropping system as per the resource availability.

• A Case Study of Drought and its Impact on Rural Livelihood in Meghalaya    Abstract  

  Both male and female counterparts of the household contribute to farming activities and livelihood. Drought affects both men and women but with different consequences according to their roles and responsibilities. Targeting interventions according to the gender roles is deemed imperative. Farmers are aware about the drought, and its negative impact on pests and disease incidence in crops, weed infestation and decrease in number of livestock, decrease in yield of meat and milk, decrease in yield of rice and other crops. Farmers are unaware of the coping strategies and mechanisms which they could adopt to reduce the risks and effects of drought due to lesser accessibility to external inputs and technologies. Site specific research and study is required to find out the suitable technology for prevailing cropping pattern and other means of livelihoods such as livestock, poultry, piggery etc.

• Predicting Land Degradation Scenario Using Cellular Automata Model in Semi Arid Regions of Andhra Pradesh    Abstract  

  Being a global phenomenon, land degradation needs to be assessed and its dynamics are to be studied for taking up any reclamative or preventive measures using state-of-the-art tools. Furthermore, equally important, is the projection of future land degradation scenario helps in formulating land use policies. Information on the spatial extent and land use pattern in conjunction with other driving factors like drainage pattern, soil texture, slope, extent of irrigated lands, aridity index, rainfall and population (both human as well as cattle) is of immense help in assessment of the vulnerability of a piece of land to degradation. Spaceborne spectral measurements hold a great promise in providing the information on land use pattern, and Geographic Information System (GIS) enables integrating it with other drivers of land degradation. The spatial-transition-based models facilitate projecting the future land degradation scenario. The study was taken up to project the land degradation scenario in part of Prakasham district of Andhra Pradesh, southern India. The approach involved studying the land use / land cover dynamics from multi-temporal Indian Remote Sensing satellite (IRS-1A/1B), Linear Imaging Self-scanning Sensor (LISS II) and IRS-1D LISS-III data for the period 1989 to 2002, vulnerability analysis of each land use/land cover category to land degradation, and projecting future land degradation scenario using cellular automata model. Validation of the model results from historical land degradation data indicated an accuracy of better than 77.6%.

• Sustainability of Henna Based Intercropping System in Rainfed Condition of Western Rajasthan: Farmers’ Perception    Abstract  

  In aberrant rainfall years, intercropping seems to be good proposition to sustain the production of henna in rainfed areas. Besides, in normal season, it increases the farm income and aims at efficient utilization of solar energy, moisture and nutrients. The present study was conducted in Pali district of western Rajasthan to ascertain the status of henna-based intercropping systems under rainfed conditions. The most important intercropping systems for the farmers ofPali district were henna + pigeonpea and henna + green gram. The important constraint perceived by the farmers in adoption of intercropping systems was low rainfall and non-availability of timely inputs. Certain researchable issues emerged from the study viz. development of suitable seed drill for intercropping systems, determination of highly profitable row ratio and development of soil and moisture conservation options for intercropping system.

• Assessment of Influence of Weather Parameters on Mesta (Hibiscus sabdariffa) in North-Coastal Zone of Andhra Pradesh    Abstract  

  Fibre productivity of mesta (Hibiscus sabdariffa) in north coastal zone of Andhra Pradesh was analysed in relation to weather parameters which revealed a decrease in productivity during seasons when rainfall exceeded 900 mm and maximum temperature during vegetative period (10-16 WAS) remained below 32.0oC. Seasonal rainfall between 600 to 725 mm resulted in high regional average yields. Increased fibre yields were observed with increasing seasonal rainfall during the years when maximum temperatures exceeded 33.5oC. Fibre yield data from a long term (14-year) experiment was found to have a strong positive association with maximum air temperature during vegetative growth (6-16 WAS) period as well as with diurnal temperature range during late vegetative period (11-19 WAS). A yield prediction model based on generated weather variables involving maximum temperature and rainfall was developed for regional yield estimation.

• Infiltration Characteristics of Alfisols under different Plant Residue Mulches    Abstract  

  Infiltration characteristics of alfisols with two types of soils having different textural composition namely sandy loam and sandy clay loam with mulching (5 cm thick) of plant residues were studied at Gunegal Research Farm of CRIDA. The study was conducted with four treatments of applying organic mulches namely castor dust, sorghum straw, glyricidia and control (without mulch). The steady infiltration rates (SIR) were significantly reduced with castor dust in both sandy clay loam (3.3 cm hr-1) and sandy loam soils (9 cm hr-1). It was followed by glyricidia and sorghum straw as compared to control (25.8 cm hr-1 and 18.9 cm hr-1 in sandy loam and sandy clay loam soils). The infiltration data were fitted to Horton, Philip and modified Kostiakov models. Three parameters model had the best description of the relationship between infiltration rate and time in the sandy loam and sandy clay loam soils. The model performance was studied by estimating the statistical parameters like SSE, RMSE and model efficiency (EF). The Philip model was observed the best fitted with observed data followed by modified Kostiakov and Horton in both sandy clay loam and sandy loam soils with model efficiency as indicator. The model efficiency with Philips model was observed maximum in all the treatments and its value ranged from 97.6 to 99.8% in both sandy loam and sandy clay loam soils under different organic mulches.

• Performance of Seed Planter Metering Mechanisms under Simulated Conditions    Abstract  

  In rainfed conditions the success of crop production depends on timely seeding. The seed rate for various rainfed crops varies from 4 to 140 kg ha-1. So, selection of a multi crop planter with replaceable metering rotor is crucial to meet the farm requirements and timeliness of operation. Though different types of planters having different seed metering mechanisms are marketed in India, single seed metered mechanical mechanisms are becoming popular as thier seeding performance is relatively better. To evaluate performance of such mechanisms quickly and optimize the parameters, a grease belt test rig was developed at CRIDA. The existing inclined plate metering mechanism and newly developed horizontal metering plate were tested for comparative performance at three speeds, 2.5, 3.5 and 5 km h-1 with castor and maize seeds using the test rig. The average number of seeds metered at different forward speeds for selected variety of maize varied from 367.5 to 239 for inclined plate and 308 to 281 for horizontal plate when compared to theoretical metered seed of 270. In horizontal plate, the seed metering was more consistent and did not varied much with respect to speed of rotor and delivered 14.02 to 4.03% higher seed rate for castor. The mean seed spacing ranged from 19.3 to 23.1 cm. The horizontal rotor metered 94 – 98 frequency percentile seeds within 15 – 30 cm spacing intervals at operation speeds of 2.5 to 3.5 km h-1. It is concluded that, correct seed rate can be achieved with the selected speed ranges by re-designing the seed cells in horizontal plate rotor.

• Improving the Existing Rainfed Farming Systems of Small and Marginal Farmers in Anantapur District, Andhra Pradesh    Abstract  

  On-farm trials were conducted during 2010 and 2011 to evaluate the effect of different interventions on productivity and profitability of rainfed farming systems of small and marginal farmers in Y. Kothapalli, Anantapur district. There was a complete failure of intercropped pigeonpea in both the years due to drought. On an average, groundnut pod yield under farmers’ practice was 194 kg ha-1. The increase in groundnut yields due to different interventions was 21% with herbicide use and 51% with use of recommended NPK. The yield increased by 155% with use of both herbicide for weed control and recommended NPK compared with farmers’ practice. However, the net returns from groundnut + pigeonpea intercropping system were negative in all the treatments (` -190 to -8,800 ha-1) due to complete failure of pigeonpea and poor groundnut yields in both the years. Among the farming systems of marginal farmers, integrated farming system involving crop production (groundnut + pigeonpea intercropping) and rearing of small ruminants (90 sheep and 30 goats) was found better with a net return of ` 1,57,855 year-1 compared to other farming systems. Similarly, among the three farming systems of small farmers, integrated farming system involving crop production (groundnut + pigeonpea intercropping) and livestock rearing (2 desi cows and 100 sheep) gave higher net returns (` 1,09,650 year-1) compared to other farming systems.

• Response of Rabi Sorghum Varieties to Potassium Levels in Inceptisol under Dryland Condition    Abstract  

  Application of potassium to sorghum varieties (M-35-1, Vasudha and Mauli) significantly increased the grain and stover yields, total potassium (K) uptake and soil available K content at harvest compared to check plots. Application of 25 kg K2O ha-1 recorded higher grain and stover yield and total K uptake, gross, net returns and B: C ratio. However, it was on par with 50 kg K2O ha-1 in terms of gross and net returns. Application of 50 kg K2O ha-1 recorded significantly higher soil available K at harvest. Among sorghum varieties, Vasudha recorded significantly highest grain and stover yield, total K uptake, net returns and B: C ratio. The K use efficiency (KUE) and moisture use efficiency (MUE) were maximum at 25 kg K2O ha-1 and further increase in K levels to 50 kg K2O ha-1 tended to decrease the efficiency. Among the sorghum varieties, M-35-1 recorded highest KUE whereas Vasudha exhibited highest MUE.

• Integrated Weed Management in Rainfed Soybean (Glycine max (L.) Merr.)    Abstract  

  A field experiment was conducted during rainy (kharif) season of 2007 at Akola, Maharashtra to study the efficacy of different weed management practices against weeds in rainfed soybean. Broadleaved weeds were predominant (65%) in the experimental field than grass weeds (35%). The highest weed control efficiency (77.1%) was achieved with pre-emergence application of imazethapyr 75 g ha-1 + in situ mulching with weeds after hand weeding 30 days after sowing (DAS). Hoeing twice at 20 and 40 DAS + hand weeding 30 DAS was the next best treatment with weed control efficiency of 74.3%. The seed yield decreased by 62.3% due to season-long weed-crop competition. Pre-emergence application of imazethapyr 75 g ha-1 + in situ mulching with weeds after hand weeding 30 DAS gave the highest seed yield (2270 kg ha-1) and was significantly superior to other treatments except hoeing twice at 20 and 40 DAS + hand weeding 30 DAS, postemergence application of imazethapyr 75 g ha-1 + in situ mulching with weeds after hand weeding 30 DAS, and preemergence application of imazethapyr 75 g ha-1 + mulching with crop residues 30 DAS. Pre-emergence application of imazethapyr 75 g ha-1+ in situ mulching with weeds after hand weeding 30 DAS gave the highest net return (` 22 568 ha-1) and benefit:cost ratio (1.79) compared to other treatments.

• Evaluation of Pigeonpea Genotypes for Delayed Sowing in Telangana Region of Andhra Pradesh under Rainfed Conditions    Abstract  

  A field experiment was conducted to study the performance of pigeonpea genotypes at different dates of sowing and spacing under rainfed conditions in clay loam soils. The experiment consisted of three genotypes [‘ICP 8863’ (Maruthi), ‘TTB 7’, and ‘WRP 1’], two sowing dates (normal and delayed) and two spacings (100 x 20 cm and 50 x 20 cm). Normal sown pigeonpea produced significantly higher yield attributes and yield compared to delayed sowing. A reduction of 23% in the mean seed yield was observed with delay in sowing by 15-30 days. Under delayed sowing, ‘ICP 8863’ (Maruthi) performed better than ‘TTB 7’ and ‘WRP 1’. However, spacing did not influence the growth and yield of pigeonpea under delayed sowing. The pod damage by Helicoverpa armigera was higher in ‘WRP 1’ and in normal sown crop, while wilt caused by Fusarium udum was higher in ‘TTB 7’. Higher net returns were obtained with early sowing and ‘ICP 8863’ (` 9720 ha-1) compared to other genotypes.

• Morphological, Physico-Chemical and Mineralogical Characteristics of Some Shrink-Swell Soils of Maharashtra    Abstract  

  Shrink-swell (vertisols and their intergrades) soils cover an extensive area especially in peninsular India. Two benchmark vertisols from Maharashtra namely Seloo (P1) from Wardha and Saikhindi (P2) from Ahmednagar districts developed from basaltic alluvium, and alluvium weathered basalt material under varying land uses were studied for their morphological, physical, chemical and mineralogical properties. The surface horizon of both the Seloo and Saikhindi soils had very dark grayish brown colour. Both the soils were very friable at the surface, friable in the subsurface horizons and the texture was clayey throughout the profiles. Seloo soils were moderately alkaline (pH 8.0 to 8.4) and Saikhindi soils strongly alkaline (pH 8.5 to 9.0) in reaction. In both the soils, the fine clay content was more than 80%. The coefficient of linear extensibility (COLE) for Seloo (0.18 to 0.26) indicated the high shrink-swell potential which commensurate with high smectite content of these soils. The lower values of EC (0.26 to 0.68 dSm-1) in combination with higher ESP (3.7 to 5.2%) in Saikhindi soils enables the soils to remain in a more dispersed state resulting in a higher degree of the problem of sodicity in these soils. Both the soils registered high CEC values, which ranged from 64.8 to 71.1 cmol (p+) kg-1 and 47.4 to 54.5 cmol (p+) kg-1 for Seloo and Saikhindi, respectively. Organic carbon values decreased with depth in both the pedons. Mineralogy of fine clay fraction was dominated by smectite with small amounts of vermiculite and traces of chlorite, kaolin and feldspar. Both Seloo and Saikhindi soil fine clays were dominant in beidellite /nontronite type of minerals.

• Nitrogen Management in Rabi Sunflower (Helianthus annuus. L) in Relation to Different Tillage Practices Imposed during Kharif    Abstract  

  A field experiment was conducted during rabi 2011 at Research farm, Regional Agriculture Research Station (RARS), Bijapur on a deep black soil under rainfed condition to study the effect of different tillage practices imposed during kharif and different nitrogen sources on rabi sunflower growth and yield. Tillage practices had no significant effect on growth and yield of sunflower crop. Yield components like number of seeds per head (1068.6) and seed weight per head (55.1 g) were significantly higher with the minimum tillage while tillage practices did not show significant influence on seed yield and stalk yield. Sunflower fertilized with 100% recommended dose of fertilizer (RDF) recorded significantly higher germination percentage, plant height, number of leaves, leaf area index, dry matter production than rest of the treatments. Yield attributes viz. head diameter (10.6 cm) and number of seeds per head (1174.8) were significantly higher with 100% RDF (35:50:35 N: P2O5 : K2O kg ha-1 ) but on par with in- situ sunnhemp green manure incorporation @ 2.5 t ha-1+ 50% recommended dose of nitrogen through urea and in-situ sunnhemp green manure incorporation @ 5 t ha-1. Seed yield (1187 kg ha-1) and stalk yield (2484 kg ha-1) of sunflower were significantly higher with 100% RDF over farmers’ practice (24:30:0 N:P2O5:K2O kg ha-1) but was on par with rest of the treatments. Reducing the tillage intensity did not significantly influence yields and substituting 50% nitrogen through organic sources produced yields comparable to that of inorganic source of nitrogen application.

• Use of Genotype x Environment Interactions and Drought Susceptibility Index for Identification of Drought Tolerant Genotypes at Vegetative Stage in Upland Rice    Abstract  

  In order to study the magnitude and consistency of yield response to drought and to identify genotypes that confer drought resistance, a series of experiments with 12 selected genotypes in advanced yield trial lower than 100 days (AYTLT 100) on the basis of observational yield trial (OYT) performance were conducted under vegetative stage drought stress and irrigated conditions at CRRI, Cuttack for three years. Significant genotype x environment interactions were observed for days to maturity, plant height, harvest index and grain yield and having homogenous error variance in environments for these characters. Among the linear and non linear components, G x E interactions were predominant for most of the characters, suggesting variation in the performance of different genotypes grown over environments could be predicted. Based on the stability parameters, the genotypes Vandana and CB 0-13-1 were found to be stable. To some extent, genotype IR 76569-259-1-1-3, RR 383-2 and Kakro may satisfy stability parameters but being low yielder, it remains questionable. Genotypic variation in drought susceptibility index (DSI) was consistent among the most of the experiments and mean DSI ranged from 0.57 to 0.91. Simultaneously, Lalsar, RR 440-167-2-13, CR 143-2-2 and IR 76569-259-1-1-3 estimated lowest DSI for yield and all component characters. Grain yield reduction due to drought ranged from 64 to 82%. The results indicated that selection for yield and yield components under stress is reliable but selection under non stress is inefficient in estimation of the yield performance of genotypes under stress condition, particularly in severe drought condition. The top genotypes under stress viz. Lalsar and CR 143-2-2 were accepted drought tolerant genotypes which may be used as the genetic sources in breeding programme. Vandana may be suggested as the best tolerant genotype for cultivation under vegetative stage drought stress.

• Genetic Divergence in Some Indigenous and Exotic Germplasm Lines of Castor (Ricinus communis L.) Under Rainfed Conditions    Abstract  

  Genetic divergences of 64 genotypes of castor (Ricinus communis L.) for nine characters were studied and genotypes were grouped in to 9 clusters. Grouping of genotypes in to different cluster was not related to their geographic origin. The genotypes from different geographic locations were grouped in to one cluster while genotypes of the same geographic origin showed genetic diversity. The cluster mean for different traits indicated considerable differences between the clusters for all traits. The genotypes of cluster I were highly divergent to those of cluster IX indicating the scope of generating heterotic hybrids through involving VP-1 pistillate line. The diversity among the genotypes, measured by intercluster distance was adequate for improvement by hybridization and selection. The maximum genetic divergence showed in Cluster VIII and IX for hybridization programme would help in achieving novel recombinants.
