Abstract
The experiment was carried out in the College of Agriculture, Orissa University of Agriculture and Technology, Bhubaneswar during rabi 2012-13. The experiment comprised of 11 treatments replicated three times in a randomized block design. Of the eleven treatments seven comprised of 100% NPK with or without organic nutrient supplements, two treatments with 50% NPK + organic nutrient supplements, one treatment with no nutrients (T1 - control) and one treatment with only bio-fertilizers. The T7 which comprised of 100% NPK (@ 150-38-63 kg NPK ha-1) application along with vermicompost (@ 2.5 t ha-1), bio-fertilizer @ 2 kg ha-1 each of Azotobacter, Azospirillumand PSB) recorded significantly higher values for plant height, weight of leaves, average knob diameter, average fresh knob weight, yield plot-1, yield ha-1 studied followed by T6. The treatment T6 had same nutrients as T7 except, farmyard manure (FYM) instead of vermicompost.

Abstract
The present research was carried out using 20 genotypes were planted in randomized block design with three replications during rabi 2012-2013 at Research Farm, Department of Plant Breeding and Genetics, Rajasthan College of Agriculture, Udaipur (Rajasthan). The observations were recorded on ten randomly selected plants for fourteen characters. Analysis of variance revealed significant differences among the genotypes for all the characters suggesting sufficient amount of variability in the experimental material under study. High GCV coupled with high heritability and expected genetic gain of a character provides good selection advantage. Association study indicated that seed yield per plant was positively and significantly correlated at genotypic level with diameter of main capsule and latex yield per plant, whereas husk yield per plant showed positive significant correlation with seed yield per plant only at phenotypic level and latex yield per plant was also positively and significantly correlated at genotypic level with days to 50 percent flowering and seed yield per plant. These associations indicated that improvement in seed yield and latex can be achieved by improving the above characters. Path coefficient analysis revealed that diameter of main capsule and days to 50 percent flowering were the major components for seed yield per plant and latex yield per plant respectively because these traits had maximum direct and indirect effect towards seed yield and latex yield.

Abstract
Seasonal abundance of the thrips and mites were studied weekly in orange plots in Rraichur. Thrips populations occur throughout the season on orange. Population peaks were observed maximum during 11th standard week (March) and minimum during 39th standard week (September). Simple correlation studies showed an increase in temperature favoured the multiplication of thrips population, minimum temperature was non significant and had positively relationship of thrips. Maximum mites population of 13.30 per leaf was recorded during 13th standard week and minimum of 0.20 mites per leaf during 35th standard week continuous shoot flushes produced by orange could play an important role in maintaining high populations of this insect. Correlation studies showed that maximum temperature had positive and non significant relationship and favoured the multiplication of mites population.

Abstract
The field experiment was laid out in a randomized block design (RBD) with 3 replications with 30 entries and the response to cold exposure was studied under controlled condition in the S. K. Sinha Molecular Breeding Laboratory OUAT, Bubaneswar, Odisha. Low temperature is one of the major environmental factors that limit the plant growth. Greengram plants of tropical origin suffer cold damage when exposed to temperature below 20°C. Cold temperature in crop plants are compounded cold snap – a lower than usual drop in temperature that causes the crop to fail due to reduce germination, retard vegetative growth by inducing metabolite imbalance and delay or prevent productive development. Each plant species has an optimum range of temperature for its normal growth and development. It varies among the genotypes within a species; the specific temperature also depends on the growth stage and development of the particular genotype.

Abstract
In view of increasing demand for fuels, extraction of oils from oilseeds is considered as a potential agri-business activity. In future, the supply of fuels resources specially the petroleum products is expected to come down both at the national as well as at the international level. In this regard, extraction of oils using the locally available resources is expected to gain prior importance. One such possibility is extraction of oils using Jatropa and pongamea. Oil rotary is an improved version of processing of oils compared to traditional method of processing. In earlier days, animal drawn stone crushers were use for extraction of oils and are popularly known as ‘Gaana’s in Kannada. Off late, stone crushers are replaced by power operated oil rotary. Power operated oil rotary has several advantages over traditional stone crushers. Firstly, oil rotary can crush more seeds per unit of time. Secondly, oil recovery percentage is much higher. Thirdly, oil rotary require less labour in comparison with the stone crusher, etc.

Abstract
The present research was carried out with 20 genotypes were planted in randomized block design with three replications during late kharif 2012-13 at Research Farm, Department of Plant Breeding and Genetics, Rajasthan College of Agriculture (MPUAT), Udaipur, Rajasthan. Analysis of variance revealed that highest GCV and PCV were obtained for number of berries per plant, dry root yield per plant, number of primary branches per plant and root diameter. In general, magnitude of PCV was higher than the magnitude of GCV. Highest heritability estimates was recorded for number of berries per plant followed by days to 75 percent flowering, dry root yield per plant, number of primary branches per plant, days to 75 percent maturity and root diameter. Expected genetic gain was observed highest for number of berries per plant followed by dry root yield per plant, number of primary branches per plant and root diameter. The magnitude and direction of correlation coefficient analysis in the present study could not explain the clear cut picture of direct association of dry root yield and its component traits. However, it can be concluded from the correlation study that emphasis can be laid on few of the component trait for improving the dry root yield in Withania somnifera as some of the component traits showed positive/negative significant association among themselves. Path coefficient analysis revealed that the characters viz days to 75 percent flowering, number of berries per plant, alkaloid content, days to 75 percent maturity and plant height were the important characters for dry root yield because these had direct effect on dry root yield. These characters also had positive indirect effect with each other. So selection for these characters would be effective in selection of suitable genotype for Withania somnifera improvement.

Abstract
Large trees take several years before they come into bearing and overall cost of production per unit area is further increased. Hence, there is over riding need to improve the existing planting system and to manipulate tree growth using canopy management to control tree growth patterns, tree shape and maintaining high fruit production of desired size and quality. Fruit thinning in the early stages of fruit growth increases size of remaining fruits, reduces trunk breakage and promotes regular bearing. Among the shoot orders studied, first order shoot pruning has beneficial effect on number of vegetative buds sprouted per pruned shoot, number of new shoots per pruned shoot, number of flower buds at leaf pair, number of flowers and fruits per new shoot, fruit diameter, average fruit weight at harvest and finally on fruit yield. Among the pruning intensities studied, pruning at 10 cm intensity advanced the vegetative bud appearance, recorded maximum cumulative length of new shoots, maximum fruit diameter at harvest, average fruit weight and fruit yield. Pruning of 30 cm has increased the number of vegetative buds per pruned shoot and number new shoots per pruned shoot along with early harvesting at colour turning stage. Pruning of first order shoot with pruning of 30 cm increased the number of vegetative buds sprouted per pruned shoot, more number of new shoots per pruned shoot, maximum cumulative length of new shoots, early first flower bud appearance and fruit yield. Among the fruit load (30, 40 and 50 fruits per tree) studied, 30 fruits per tree recorded the minimum number of days taken for harvesting at colour turning stage and maximum average fruit weight at harvest. However, maximum fruit yield was noticed with 50 fruits per tree. The treatment combination of first order shoot pruning at 30 cm with 50 fruits per tree has recorded highest fruit yield per hectare with quality fruits. However, the quality of fruits in control and other treatments was also at par.

Abstract
The study was conducted in Rajodha micro watershed in Porsa block of the Morena district of Madhya Pradesh during 2010-11. To assess the impact of watershed development programme a benchmark survey was under taken on management practices. The noticed positive effect of the programme was an increase in area of arhar and wheat and an increase in productivity of gram and arhar with an increased change in arable areas, agricultural areas, irrigated areas, cropping intensity, water resources, and area of horticultural crops. The cattle population was also increased due to sufficient water and fodder availability. Using modern inputs like high yielding varieties, chemical fertilizers, irrigation, and plant protection measures etc. has also increased the productivity of crops. The co-ordination of farmers and government functionaries, land development activities were some of the measures taken to improve the Rajodha Micro Watershed. Better co-ordination between development agencies and voluntary organizations is also essential for effective implementation of watershed programme.

Abstract
A field experiment was conducted at the Kerala Agricultural University during December 2012 to March 2013 to study the relative efficiency of fertigation over conventional irrigation and fertilizer application in summer grown oriental pickling melon. The experiment was laid out in randomized block design (RBD) with three replications. The treatments consisted combinations of four irrigation levels (50, 75 and 100% Ep through drip irrigation and farmers practice of pot irrigation) and three fertilizer levels (100, 150 and 200% recommended dose of fertilizer). Results shows that yield and water use efficiency differed significantly among the treatments. Consistently high yields (72.4 t/ha) and nitrogen use efficiency (88.48 kg fruits/kg N) were noted when the crop was drip irrigated at 100 percent Ep and fertigated with 140 and 70 kg N ha-1. Higher water use efficiency (292.07 kg ha-mm-1) was recorded with crop irrigated through drip at 50 percent Ep and fertigated with 140 kg N ha-1 followed by drip at 50 percent Ep and fertigated with 120 kg N ha-1.

Abstract
In this investigation an attempt has been made to study the growth, trends and price volatility of futures and spot prices of mustard, guar and gram seeds. For this purpose secondary data were used. The data were collected from the reports, records and related articles of the commodity exchange, its authorized brokers and trading members, website of BCEL and from Krishi Upaj Mandi, Bikaner for the financial years 2003 to 2008 for futures prices and 2000 to 2008 for spot prices. Growth in monthly prices was estimated with the help of exponential function and trend in monthly prices by fitting quadratic function. Means, standard deviations and coefficients of variation were calculated to study the impact of futures trading on price volatilities. Both the prices futures and mandi spot prices- for mustard, guar and gram seeds recorded significant growth during the study period. The trend in monthly futures and mandi spot prices of mustard, guar and gram seeds was noted to be curvilinear in shape during the study period. The shape of the trend curves for mustard and gram prices was concave downwards and that for guar seed convex upwards, i e dome shaped. Concave downwards trend indicated that initially the price decreased and then increased. In case of convex upwards trend, the situation was just reversed. The spot prices of mustard seed and guar seed recorded an increase over time but the increase in futures prices during the futures period was significantly higher than the increase in spot prices. The standard deviations in spot prices of mustard seed and guar seed did not significantly differ from that in futures prices for these commodities during the futures period. The variability in spot and futures prices of the selected commodities in futures period was low.

Abstract
The present investigation was carried out during kharif season of 2011-2012 at the Vegetable Research Farm, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P). The experimental material for the present investigation was comprised of 20 genotypes of okra. These genotypes were sown in randomized complete block design with three replications, to estimate the genetic variability, correlation and path coefficient analysis. Observations were recorded on the basis of five random competitive plants selected from each genotypes separately for morphological, phonological, yield and other parameters were evaluated as per standard procedure. Analysis of variance revealed highly significant variance for all the characters. Presence of such variability in the population under study is the ultimate result of variability in the genetic constitution of various individuals. High heritability coupled with high genetic advance for trait plant height at 30 DAS, plant height at 60 DAS and number of seeds per fruit suggested the prepondance of additive genes. Genotype Okra-hy-10 was recorded the maximum yield per plant (303.00 g) which revealed that it was better genotype in relation to yield under Jabalpur condition.

Abstract
Present investigation was carried out during kharif 2013, 29 greengram genotypes comprising of nine parents and 20 crosses were evaluated for yield and its components. Analysis of variance revealed that significant differences among the genotypes for all the characters studied. Estimates of phenotypic co-efficient of variation (PCV) were higher than genotypic co-efficient of variation (GCV) for all the characters. Higher PCV and GCV were recorded for number of branches/plant, clusters/plant, pods/plant, dry weight/plant and tolerance to MYMV, respectively indicated existence of large genetic variability for these characters in the material studied. High heritability coupled with high genetic advance as per cent of mean was observed number of branches/plant and tolerance to MYMV in parents and for number of branches/plant, clusters/plant, pods/plant, dry weight/plant, tolerance to MYMV and seed yield/plant in crosses suggesting that involvement of additive gene action for these characters. Hence, phenotypic selection based on these characters in the segregating generations would be more effective and rewarding.

A field experiment was conducted during 2012-13 at All India Coordinated Research Project on Linseed, Dr. P. D. K. V, Nagpur, with thirty two hybrids produced by line × tester mating design with eight lines viz A-95B, EC-1392, EC-1424, IC-15888, GS-234, JRF-4, JRF-5, F-14 and four testers viz NL-97, PKVNL-260, Padmini, Neelum to study heterotic effects of yield traits like days to 50% flowering, days to maturity, plant height, number of branches plant-1, number of capsules plant-1, 1000 seed weight and seed yield plant-1. The heterosis over MP and BP for seed yield/plant ranged from -45.51 to 144.15% and -50.14 to 127.92%, respectively. Three crosses Padmini × GS-234, Padmini × F-14 and Padmini × EC-1392 showed significant heterobeltiosis as well as midparent heterosis for seed yield plant-1. These crosses also had significant and positive heterosis for number of branches plant-1, number of capsules plant-1 and would be more desirable to exploit heterosis in linseed. There is every possibility of getting a cross with lower mean performance but high heterotic response in case the parental performance is very poor and vice-versa. The mean performance being the realized value and the heterotic response being an estimate, the former should be given due consideration while making selection of cross combinations.

Abstract
Lablab bean (Lablab purpureus L. sweet var. Typicus) cultivars viz Kelashi wal and Pavata were mutagenised with physical mutagen namely, gamma radiation (100, 150, 200 Gy) on various agronomical traits at Department of Agricultural Botany, Dr. B. S. K. K. V. Dapoli, Ratnagiri during rabi 2011-12 and 2012-13. In M1 generation, germination and survival percentages of seedling, plant growth and pod per plant parameter was adversely affected with increase in dose indicating almost a linear relation but in M2 generation, these agronomical traits did not follow any specific order according to the strength of dose. The first flowering was slightly delayed in the treatment than the control. All remaining characters did not show much variation in mean values than control in kelashi wal except grain yield per plant. In kelashi wal high yielding mutants were isolated. Also, in M2 generation, gamma-rays induced only ‘Xantha’ type of chlorophll mutations was found and based on the chlorophyll mutation frequency on M2 plant basis mutagenic effectiveness and efficiency were computed. Variability studies revealed that 100 Gy dose was effective in kelashi wal. Induced variability indicated that significant improvement can be achieved by appropriate selection methods. A large number of useful mutants for different character were observed in different population. These mutants are to be evaluated and assess their stable performance, involve them in crop improvement programme and to isolate productive mutants.

Abstract
Intensive cropping systems with fertilizer responsive crops that rely on high input of inorganic fertilizers often lead to non-sustainability in production and also pose a serious threat to soil health. However, considering economics and also physiological potential of varieties, entire dependence on organic sources of nutrients may not be adequate to attain the most productivity. Hence integrated nutrient management with both organic and inorganic fertilizers was investigated. A field experiment was conducted to study the cumulative effect of organic and inorganic fertilizers on soil health in turmeric + maize intercropping system. Application of inorganic fertilizers in conjunction with two types of organic manures (FYM and poultry manure) and tanksilt significantly increased the soil properties like water holding capacity, infiltration rate, organic carbon, available NPK and Fe in soil, while the bulk density decreased. The soil properties improved with increase in the level of inorganic fertilizers combined with organic manures and the treatment full RDF + poultry manure (PM) registered the maximum.

Abstract
A field experiment was conducted at Central Coffee Research Institute Research Farm in split-split plot design for standardization of optimum planting densities and training methods for two dwarf Arabica genotypes viz S.4634 and Cauvery. Among the two varieties, irrespective of variations in planting densities and topping heights, the S.4634 recorded significantly higher yield of 1182 kg clean coffee ha-1 when compared to Cauvery (969 kg cc ha-1) over 10 cropping seasons. Among the planting densities, the coffee planted at closer spacing of 5 × 5' (4000 plants/ha) recorded significantly higher yield for ten years (1264 kg cc ha-1) as compared to other spacings of 6 × 5' (3333 plants/ha) and 6 × 6' spacing (2777 plants/ha) (1063 and 900 kg ha-1 respectively). With respect to training methods the pooled data over the 10 years indicated that the coffee plants trained on single stem and topped at two tiers (2.5' and 5') recorded significantly superior yield (1125 kg cc ha-1) as compared to plants trained on single stem and topped either at single tier (3.5') or at three tiers (2.5', 4.0' and 5.0') which recorded 1057 and 1047 kg ha-1 respectively. The interaction effects between spacing and topping was found to be non-significant in both varieties (S.4634 and Cauvery). The results revealed that a plant population of 4000 plants/ ha and training on single stem with two tier topping is ideal for dwarf Arabica varieties under natural shade grown conditions in India.

Abstract
The productivity of rice in the mid altitude temperate ecologies of Kashmir valley continue to be quite low on account of several biotic and abiotic stresses. Low temperature during the nursery period causes cold stress, which adversely affects seedling growth. Unavailability of quality seed of suitable cold tolerant varieties and lack of knowledge about related production and protection technologies are other reasons for low crop yield. In view of these, an effort was made to boost the rice production through on farm testing and frontline demonstrations of improved rice variety and its recommended production and protection technologies at farmers’ field. On-farm testing of different varieties revealed that rice variety K-448 (Jehlum) registered a high yield potential of 60.0 q/ha as against 38.0 q/ha of the local check with a yield advantage of 22.52% over farmers’ practice in frontline demonstrations. Use of modified protected nursery shortened the nursery period, provided healthy seedling and reduced crop duration which is important for profitable double cropping under temperate conditions. This technique further improved yield by 12% over open nursery. K-448 gave maximum returns of ` 58662.0 against ` 48145.0 from the farmers practice The study reveals that rice production can be greatly increased in the mid altitude temperate regions of Kashmir by the use of improved variety (K-448) and recommended production and protection technology.

Abstract
Nutripellet pack has 3 parts viz top bioinoculant mixture; central manure pellet and bottom fertilizer pellet. On the top bioinoculants mixture responsible for N2 fixation, P and Zn solubilization and biocontrol agents are placed as a powder or granules. Highly decomposed manure having C:N ratio below 30:1 enriched with P, micronutrients and pesticide/fungicide is pelleted with pelleting device and placed at the centre. At bottom a mixture of NPK fertilizers made in pellet form and encapsulated in polymer paper (bio degradable) pouch is placed. The nutrients in fertilizer pellet are in amount equal to the yield target of the crop. To study the Nutripellet (Nutripellet is a packet in tubular form having several inputs viz fertilizers, manures (For preparing manure pellet, enriched vermicompost was used), fungicide and bioinoculants) application of nutrients on the yield of marigold (Tagetes erecta L), a green house experiment was conducted with following treatments viz T1: Control; T2: 100% NPK Nutripellet Pack (DAP- Diammonium phosphate as P source) and T3: 100% NPK Nutripellet Pack (SSP- Single super phosphate as P source). The results of the experiment indicated the Nutripellet pack with NP (DAP) K recorded long root length (39.0 cm), high root dry weight (4.2 g) and high root volume (35.5 ml) followed by Nutripellet pack with NP (SSP) K. The highest population of bacteria, fungi and actinomycetes were observed in Nutripellet pack with NP (SSP) K. Inner core had high available N, P and K when compared to outer core. Organic C was high in manure pellet before soil placement (31.8 %). After placement in soil organic C of manure pellet without plant was low (26.3%) and with plant was lowest (19.8%). Wider C: N ratio was recorded in manure pellet before soil placement (24.6:1), whereas narrow ratio was in soil without plant (16.3: 1) and with plant (15.4: 1).

Abstract
Samagra project on banana cultivation is a flagship project with multi-stakeholder partnerships in Kerala. The primary aim of this research study was developing a Likert’s summated rating scale with which to measure farmers’ attitude towards Samagra (Comprehensive banana project). The research was started by identifying 50 different statements based on review of literature and information obtained from various stakeholders and experts of the Samagra project. Out of these statements, 20 items were selected and ultimately only 6 consistent and reliable statements were retained for inclusion in a five point Likert’s type scale. The 6 statements’ scale was administered on 60 randomly selected sample farmers to measure their attitude towards Samagra. The result shows that 40 percent of the beneficiaries had neutral attitude towards ‘Samagra’ and 60 per cent of the beneficiaries had favourable attitude towards Samagra’. None of them had unfavourable attitude towards Samagra’. This detailed study together with strict follow-up of data collection from the sample respondents has been extremely useful in developing a relatively consistent tool to measure farmers’ attitude. Therefore, the 6 items five point Likert’s scale can be applicable rest of the Indian states also.

Abstract
Chittoor district was purposively selected since the groundnut crop contributes 34.5 percent of the total cropped area in the district. Of the 66 mandals, Thamballapalli mandal was selected based on the percentage of gross sown area under groundnut to the gross sown area of district. A three stage sampling technique was adopted for the selection of groundnut growers. In the first stage, mandal with highest percentage of area under groundnut was selected and in the second stage the villages with sufficiently large area under groundnut were selected purposively to ensure the adequate number of groundnut growers from the revenue villages selected randomly in final stage. The ultimate sample size was fixed as 60 and evenly distributed to the four selected villages. The study relied on both primary and secondary data. The reference period of the study was 2010-11. The study analyzed supply response on area and problems in marketing of groundnut in Chittoor district. The supply response analysis showed the price responsiveness of the groundnut growers on area. The study also found that price fluctuation and forced sale were the major problem for the groundnut farmers.

Abstract
An experiment was carried out at Main Research Station (MRS), University of Agricultural Sciences, Hebbal, Bangalore during kharif season of 2010 to study the weed compost preparation and to know changes during the process of composting. Aquatic weeds such as water hyacinth and alligator weed were collected from the Hebbal tank and used as raw materials for compost preparation. Cow dung and microbial inoculum with a mixture of Pleurotus sajorcaju, Phanerochaete chrysosporium, and Trichoderma harzianum were used as additives. The compost was analyzed for physical, chemical and biological changes during different intervals of composting period. By the end of composting period, physical changes like moisture of composts stabilized to around 30-35 percent which is optimal, there was drastic reduction in volume of organic residues, temperature increased at initial stage and on the 60th day the temperatures of the pile was optimal. Water hyacinth compost has got neutral pH (7.20) as compared to alligator weed (6.50) compost. EC and Organic carbon content of water hyacinth compost was higher than alligator weed compost. The C:N ratio of matured water hyacinth compost was 13.20 whereas alligator weed compost was 11.20. By the addition of additives like microbial culture and cow dung there was increase in the secondary and micronutrients content of the mature compost of water hyacinth and alligator weed. The biochemical properties like lignin and cellulose contents decreased as the compost get matured due to breakdown of complex structure of lignin and cellulose.

Abstract
The experiment was conducted to study the association among stay-green, charcoal rot resistance and yield traits using six generations (P1, P2, F1, F2, BC1P1 and BC1P2) derived from two crosses viz M 35-1 x CSG 0818 (cross 1) and CSV216R x CSG 0818 (cross2). Plants were inoculated with Macrophomina phaseolina using toothpick technique. Stay green observation was recorded using SPAD meter instrument at weekly interval after flowering up to physiological maturity for three weeks. In both the crosses, the association between SPAD readings and charcoal resistance traits (number of nodes crossed and length of spread) was negative. However, in the cross 1, the association between SPAD2 and number of nodes crossed was negative. And in the cross 2, negative association between SPAD1 and number of nodes crossed, and between SPAD3 and mean length of spread was noticed. In both the crosses, grain yield and fodder yield were positively associated with SPAD1 and SPAD2. All the SPAD values were positively associated with plant height, panicle weight, panicle length, and were negatively associated with days to 50% flowering in both the crosses. Only in cross1, the association between SPAD and 1000 seed weight was positive and. In both the crosses the association of grain and fodder yield was positively correlated with other yield traits.

Abstract
An in-vitro study was conducted to check the stability of xylanase, cellulase, pectinase and phytase at different pH (4.0, 6.0 and 7.0) and temperature (40°C and 42°C) in enzyme premix. The above enzyme premix in dry form was added at the rate of 2 g/kg of broiler starter mash feed and their stability was studied during different storage periods (0, 7, 14 and 21 days) by extracting the individual enzymes. Xylanase showed significant (p<0.05) reduction in activity with the increase in pH and more stability at pH 4, whereas temperature had no significant (p>0.05) effect on xylanase except at pH 6, but cellulase and phytase exhibited stability at different pH and temperature combinations. Pectinase activity decreased significantly (p<0.05) with increase in pH as well as increase in temperatures except at pH 6. The extraction efficiency of phytase, pectinase, cellulase and xylanase were 30.15%, 32.80%, 41.60% and 65.91%, respectively in spite of adding these enzymes more than the recommended level in the broiler feed. The study also showed that xylanase and pectinase had good stability up to 21 days of storage, where as cellulase and phytase were stable only up to 7 days of storage.

Abstract
The study is based on the time series data on area, production, productivity, per capita consumption, export and import of fruits and vegetables for the period from 1991-92 to 2011-12 analyzed using compound annual growth rate. The growth in area, production and productivity of fruits and vegetables has increased at all India level after the introduction of NHM by Government of India. Karnataka state experienced an increase in growth in area and production of fruits while the growth in productivity was negative after the implementation of the programme. The growth in area and production under vegetables in Karnataka has decreased but positive while the growth in productivity of vegetables was negative after the implementation of the programme. Increasing in scarcity of human labour, irrigation water and other inputs resulted in higher cost of cultivation and reduced income from agricultural crops led to diversification of crops from low value agriculture to high value, less risky dry land horticultural crops. Introduction of NHM in the country has enhanced the export growth in all the categories of fruits while the export growth in different categories of vegetables was negative. In India, Majority of the fruits exported to South Asian and Middle East countries while the vegetables were exported to USA, Japan, Germany, France, United Kingdom, Netherlands, Canada and Belgium.

Abstract
The bioefficacy and phytotoxicity of formulations of tebuconazole 2% DS was evaluated for germination and seedling mortality, the management of collar rot and tikka disease of groundnut and its effect on dry pod yield. Application of tebuconazole 2% DS % @ 1g, 2g and 4 g/kg seed to groundnut kernels prior to sowing was found to be highly effective, when used @ 4 g/kg seed, in the management of collar rot and tikka disease of groundnut with least disease severity (14.78%) in 2010 while 13.22% in 2011 where pooled PDI was 14.00% with higher pod yield (23.08 q/ha) in 2010 while 19.66 q/ha was recorded during 2011 whereas pooled yield data was 21.37 q/ha and similarly, least PDI (13.22%) noted in 2011 with higher pod yield (23.08 q/ha) during 2010-11. The fungicide was also very effective in farm and large scale demonstration trials in controlling the tikka and collar rot and also resulted higher percent increase in yield (35.15%) over check fungicide (Raxil- Tebuconazole 2% DS) i e 11.60%. Hence, it reduce the seedling mortality when the tebuconazole 2% DS applied @ 4 g/kg seed. The maximum severity (39.43%) of tikka disease was recorded during 2010 while 32.93 % PDI of tikka was noted in 2011 whereas 36.18% PDI in pooled. Similarly, 16.24 q/ha pods yield was recorded in pooled during 2010 and 2011.

Abstract
Fifty genotypes of blackgram were grouped into eight clusters by using D2 analysis. Cluster IV recorded highest mean value for number of pods per plant, number of pods per cluster and pod length. Cluster VI consisted maximum mean value for number of clusters per plant, 100 seed weight. Cluster VII showed highest mean value for days to initial flowering, pod initiation, days to maturity. Cluster VIII recorded the highest mean value for number of seeds per pod, number of branches per plant, plant height, days to 50% flowering, number of seeds per plant, seed yield per plant. Based on cluster means and divergence, it was concluded that the hybridization between genotypes from two divergent clusters could produce desirable recombinants for grain yield. The analysis of variance revealed significant differences among the genotypes for all the characters studied indicating that the genotypes represented wide variability. The estimates of phenotypic coefficient of variation (PCV) were higher than the estimates of genotypic coefficient of variation (GCV) for all the traits under study indicating the environmental influence over the traits. High heritability along with high genetic advance as percent of mean was indicative of additive gene effects and could be improved through selection of number of pods per plant, number of seeds per pod, seed yield per plant, number of pods per cluster, number of clusters per plant, number of seeds per plant. The association of high heritability with high genetic advance was indicative of additive gene effects and could be improved through selection of these traits.

Abstract
The present study was conducted in the Gulbarga district of Karnataka State during 2011-12. Total sample for the study was 120 respondents. Impacts of climate change is the degree to which, severity of climatic parameters like rainfall and temperature, and their ill effects on crop production aspects and water resource availability. significant changes occurred before and after the year 2005, changes in the month of land preparation, date of sowing, germination percentage of seeds, crop growth, flowering time, pod formation and number of pods and incidence of pest was more after the year 2005 as compare to the before the year 2005 due to the variation in the parameters of climate change (rainfall and temperature) on Red Gram. And also after 2005 there was increase in the temperature. This might have increased the infestation of pest and diseases because of this infestation decreased yield in the red gram as compare to before 2005, at the same time 37.50 percent of high yield may be because of the use of hybrid seeds and other technologies usage in the production of Red gram.
