Abstract
An investigation to evaluation of varieties and hybrids of rice (Oryza sativa L.) in SRI cultivation was conducted at Directorate of Rice Research farm, ICRISAT campus, Patancheru, Hyderabad during kharif 2013. Growth attributes (dry matter accumulation at 50% flowering and maturity, root length and root volume), yield attributes (number of effective tillers m-2, panicle length, total number of seeds per panicle, number of high density seeds per panicle, number of filled seeds per panicle and 1000 seed weight) recorded significantly higher values in SRI (System of Rice Intensification) compared to Conventional Transplanting (CT). SRI method produced significantly higher seed yield (5851.71 kg ha-1) and straw yield (7176.84 kg ha-1) than CT. Hybrids was found significantly superior in other varieties. Hybrid (US 382) recorded the highest number of effective tillers m-2, total number of seeds per panicle, number of high density seeds per panicle, number of filled seeds per panicle, 1000 seed weight, seed yield (6765.72 kg ha-1) and straw yield (8234.40 kg ha-1). Hybrids respond well for SRI method than conventional transplanting method.

Abstract
The biochemical analysis of Aspartate aminotransferase and Succinate dehydrogenase in twelve bivoltine silkworm genotypes viz. NB4D2, SH6, Meigitsu, CSR4, Sheiki II, Pampore-5, J122, J2M, 14M, JBEL, NJ3 and B38 was done using native-polyacrylamide gel electrophoresis. Considerable amount of polymorphism was shown by both aspartate aminotransferase and succinate dehydrogenase. In all five bands and six isozymic forms were recorded in both the isoenzyme fingerprints. The relative mobility, in case of aspartate aminotransferase, ranged from 0.31 to 0.73 and the intensity score ranged from 3 in B38 to 6 in NB4D2, SH6 and Meigitsu. In succinate dehydrogenase, the relative mobility ranged from 0.41 to 0.78 and the intensity score from 5 in J122, J2M, 14M, JBEL, NJ3 and B38 to 10 in NB4D2. Out of ten bands observed in the two isoenzyme systems, two were monomorphic and eight were polymorphic. Moreover, the isoenzymes showed an appreciable range of relative mobility and activity, thus, suggesting their use as a marker for silkworm characterization. Further, the isoenzymes were found significantly and positively associated with single cocoon weight, single shell weight, cocoon yield/10,000 larvae by number and cocoon yield/ 10,000 larvae by weight. Hence, the enzymes could be utilized in Marker Assisted Selection programmes in silkworm breeding.

Abstract
A field experiment was conducted during kharif season of 2013-2014 to assess the magnitude of genetic diversity for morphological as well as maturity and yield attributing traits in 45 genotypes of alfalfa. The experiment was laid out in a randomized block design with three replication at Experimental Farm of Regional Agricultural Research Sub-station, SKUAST-Kashmir, Kargil. The genetic divergence among 45 genotypes of alfalfa were grouped into seven clusters with cluster I having maximum number of genotypes (11) followed by cluster IV with 10 genotypes, cluster II and III with 9 genotypes, cluster VI with 3 genotypes, cluster V with 2 genotypes and cluster VII with 1 genotype. The maximum intra-cluster distance was observed in cluster IV (37.05). The maximum inter-cluster distance was observed between cluster V and Cluster VI (833.92). Cluster I and VI exhibited higher mean values for most of the characters studied while the lowest cluster mean for all the characters except days to 50% flowering, number of flowers raceme-1 and crude protein content of leaves were recorded in cluster V. Highest percent contribution of divergence come from green fodder yield plant-1, seed yield plant-1 and plant height.

Abstract
The present study was undertaken in the ongoing long-term fertilizer experiment initiated during 1972 at Experimental Farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur in randomized block design with eleven treatments replicated three times. The soil of the experimental area was silty loam and classified taxonomically as “Typic Hapludalf”. Surface (0-0.15 m) and sub-surface (0.15-0.30 m) soil samples taken after the harvesting of wheat (2011-2012) were analyzed for different fractions of potassium. Continuous application of chemical fertilizers either alone or in combination with FYM or lime for forty years influenced different fractions of potassium significantly. Continuous cropping without fertilization resulted in depletion to the order of 21.5, 16.6, 11.7 and 5.5 per cent in water soluble, exchangeable, 0.5 N HCl extractable, non exchangeable-K, respectively. Application of FYM and lime along with 100 per cent NPK resulted in significantly higher K uptake by both the crops compared to other treatments. Exchangeable potassium exhibited highest correlation with available potassium in surface as well as sub-surface soil layer. Different fractions of potassium were found to be positively and significantly correlated potassium uptake by wheat and maize crops

Abstract
It has been found earlier that during different seasons in a year, number of farmers seeking technical guidance regarding agriculture and allied fields varied to a large extent. Hence, efforts were made to diagnose farmers’ technological problems pertaining to insect pest, diseases and nutrient deficiency symptoms in rabi crops. During the last 3 years i.e. from 2013 to 2015, record of all the visiting farmers was maintained in the plant health diagnostic laboratory at the Krishi Vigyan Kendra (KVK) in which complete details of the farmer with address and contact number was maintained. The study revealed that out of 95 farmers who visited the KVK campus with queries pertaining to wheat crop, per cent farmers visited during the month of April, May, June, July, August, September and October were 10.4, 8.6, 2.3, 23.5, 15.2 and 40.1, respectively. It was found that 47.3 per cent farmers enquired about seed treatment in wheat and 9.1 per cent samples showed manganese deficiency symptoms. Twenty farmers visited KVK with samples infested with the attack of aphids. Among the diseases, wheat crop was found to be damaged by yellow rust only caused by Puccinia striiformis West and that too in the month of February and March. 33.3 per cent samples were brought by the farmers in the month of February and 65 per cent samples in the month of March. Like wheat, gram was also found prone to attack of insect pest and diseases. A total 62 farmers visited the KVK with queries pertaining to the gram crop during September to March months in which 75.8 per cent farmers enquired about seed treatment. Most common problem faced by the farmer was attack of H. armigera on the gram crop. Its population starts developing in the month of January and attained its highest peak in the months of February and March as was revealed by the number of samples received. Thus, it can be said that most important task was identification of the disease, attack of insect pest or deficiency symptoms of the nutrient so that proper remedial measured can be taken up timely

Abstract
The present study was carried out to evaluate the 45 genotypes of alfalfa for forage yield and yield components during two successive growing seasons under the Cold Arid Region of Ladakh. The genotypes exhibited a wide range of variability for all the traits studied. The estimates of phenotypic coefficient of variation (PCV) in general, were higher than the estimates of genotypic coefficient of variation (GCV) for all the characters. The characters viz. days to 50% flowering, plant height at 50% flowering, green fodder yield plant-1 and leaf fresh weight showed high GCV estimates. All the studied characters showed high to moderate heritability except for number of flowers raceme-1, number of pods raceme-1 and number of seeds pod-1. The genetic advance for the characters ranged from 0.51% (1000-seed weight) to 54.13% (plant height at 50% flowering) and genetic advance as per cent of mean ranged from 9.71% (number of flowers raceme-1) to 51.62% (leaf fresh weight).

Abstract
Herbicidal effects of aqueous leaf extracts of Calotropis gigantea (L.) were evaluated against germination and growth of the noxious alien weed Parthenium hysterophorus L. Aqueous leaf extracts of 0, 25, 50 and 75% w/v concentrations obtained from leaves of Calotropis gigantea (L.) inhibited germination and seedling growth of P. hysterophorus in bioassays conducted in petriplates. In foliar spray bioassay, aqueous leaf extract of 25, 50 and 75% w/v sprays were given in two times at five day intervals viz. one-week and two–week old pot grown Parthenium seedlings. The extracts on potted plants resulted in reduced seedling germination and higher concentration of 50 and 75% leaf extracts was completely inhibited the seedling growth, seedling biomass and biochemical parameters viz. protein and chlorophyll content. The present study concludes that leaves of Calotropis gigantean (L.) contain potent herbicidal constituents for suppressing the growth of Parthenium weed

Abstract
A field experiment was conducted at the Research Farm, College of Agriculture, Indore, during kharif season of 2015 under All India Co-ordinate Research Project for Dry land agriculture to study the diminishing effect of aberrant weather conditions through foliar spray of chemicals. Maximum crop growth rate (0.29 g m-2day-1), relative growth rate (0.149 g g-1day-1), chlorophyll content (41.15), seed yield (365 kg ha-1) and rain water use efficiency (0.54 kg ha-1-cm) was recorded under application of foliar spray of thiourea solution @ 250g ha-1 + Trizophos @ 600 ml ha-1 tank mix at 29 and 60 DAS as compared to remaining treatments and absolute control. On the basis of above findings, it may be concluded that foliar spray of thiourea @ 250 g ha-1 + Trizophas @ 600 ml ha-1 (tank-mix) at 29 and 60 DAS gave higher growth rate and, seed yield as well as rain water use efficiency under aberrant monsoon conditions (Dry spells during seedling, and reproductive stages).

Abstract
The present investigation comprised of sixty genotypes of fennel (Foeniculum vulgare L.) was undertaken to characterize the genotypes based on morphological plant growth characters like seedling colour, plant growth habit, early plant vigour, plant height, number of primary and secondary branches and days to seed germination. All these plant growth characters clearly differentiated the genotypes into different groups. All the genotypes were categorized based upon different characteristics as based upon seedling colour, five genotypes were grouped as dark green and fifty five as light green seedling colour, based on plant growth habbit, four genotypes were grouped as erect, forty eight as semi-erect and eight genotypes observed as spreading, based on early plant vigour, fifty five genotypes comes under very good plant vigour and five genotypes comes under good plant vigour, on the basis plant height forty nine genotypes characterized as tall (>130 cms), three genotypes as dwarf (<110 cms) and eight genotypes medium height (110-130 cms), on the basis of number of primary and secondary branches per plant sixty genotypes characterized as less branches (<10) and more branches (>10), thirty four genotypes grouped as less primary branches and twenty six as more primary branches per plant. Similarly, fourteen genotypes observed as less secondary branches per plant and forty six observed as more secondary branches per plant. Days to seed germination differentiated as early (<10 days), mid early (10-15 days) and as late (>15 days) and it’s found that more genotypes recorded days to seed germination in late group. The identification key based on seed characters, showing higher resolution in terms of differentiating the genotypes was prepared. The study is important to differentiate the available fennel germplasm for registration without any legal problems related to IPR issues of plant variety protection.

Abstract
Increasing concern over food security was a feature behind the estimation of resource use efficiency of crops. Present study explored the resource use efficiency and returns to scale in irrigated paddy in Central Dry Zone (CDZ) of Karnataka. Primary data were collected from 90 farmers for the study. Cobb-Douglas production analysis and Data Envelopment Analysis was used. The results on efficiency of input use in borewell irrigated paddy cultivation by farmers indicated that, the elasticity of production for borewell water (0.75%), fertilizers (0.44%) and seeds (0.18 %) were positive and statistically significant. There is still greater scope for increasing the level of use of borewell water, seeds and fertilizers to obtain economic optimal level of gross returns as indicated by greater than unity of marginal value product to marginal factor cost (MVP/MFC) ratio and realize more output than the present level. But in case of elasticity coefficient for machine hours and capital cost, they are not relevant and failed to exert any significant influence on gross returns. Among the major irrigated crops in CDZ, allocative efficiency scored impressively in irrigated paddy (0.79) higher than the other crops.

Abstract
The present experiment was carried out at the Department of Genetics and Plant Breeding, Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India to study the effect of imposed drought on relative water content, chlorophyll content and proline accumulation in five drought tolerant (PL-406, IPL-324, LL-1146, IPL-325, K-75) and five drought sensitive (L1112-20, LP-112, ILL-10803, KLS-113, KLS-107) genotypes of lentil (Lens culinaris Medik.). For this purpose, the genotypes were grown under both control (0.0 bar) and drought stress (-9 bar) condition by using PEG- 6000 as osmoticum. The experiment was laid out in an asymmetrical factorial completely randomized design with three replications. Roots, shoots and leaves of ten days old seedlings were harvested and physiological and biochemical analyses were carried out for the above parameters. From the study it was revealed that relative water content and chlorophyll content (chl a, Chl b, total Chl) were reduced, while proline content was increased due to imposition of drought stress with compared to respective control. However, the tolerant genotypes exhibited lower relative reduction for RWC and chlorophyll content and proline content increased more as compared to susceptible ones under drought stress condition. The results suggested that higher levels of RWC, chlorophyll content and proline accumulation in tolerant variety of lentil could play an important role in drought stress tolerance.

Abstract
The field experiment was conducted for consecutive two years (2009-10 and 2010-2011) at Agro forestry Research Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra, India in three years old Jatropha plantation raised at spacing of 3 m x 3 m in Entisol with low soil available nitrogen and high potassium status. The treatments were comprised of three levels of irrigations viz. No irrigation (I0), One irrigation (I1) at sprouting and two irrigations (I2) at sprouting and seed formation, three levels of nitrogen (N0, N1, N2) 0, 45 and 90 kg N ha-1 and three levels of potassium (K0, K1, K2) 0, 30 and 60 kg K2O ha-1. The treatments were replicated four times in split -split plot design. The pooled results revealed that significantly higher seed and oil yield of Jatropha was recorded with (I2) two irrigations at sprouting and seed formation over (I1) irrigation at sprouting and no application (I0). Among nitrogen levels, significantly higher seed and oil yield of Jatropha was recorded with (N2) 90 kg N ha-1 over 45 kg N ha -1 and 0 kg N ha-1. Application of 60 kg K2O ha-1 recorded significantly higher seed and oil yield of Jatropha. The interaction effects of irrigation, nitrogen and potassium levels were recorded maximum yield of Jatropha. This is mainly because of the significant influence of combined application of nutrients on yield of Jatropha. Specific gravity, viscosity, distillation temperature, flash point of Jatropha oil has no significant difference due to different levels of irrigation, nitrogen and potassium. The Jatropha oil properties viz. specific gravity, viscosity, distillation temperature, flash point was compared with the ASTM and BIS standard. These properties were found within standard range.

Abstract
Water and labor shortage in agriculture is leading to major changes in rice cultivation. As a result direct seeding, may be dry or wet, practice in rice is and will gain more and more importance. However, often the heavy rains at the time of seeding create anoxic/anaerobic conditions for seed germination and drastically reduce germination percentage and crop establishment. Thus, the development of tolerant varieties towards anaerobic conditions during germination is essential. Identification of QTLs is required for precise selection and breeding for anaerobic germination. For this, 122 recombinant inbred lines (RILs) in F14 generation of two indica genotypes, Danteshwari and Dagad deshi along with 16 checks were phenotyped under anaerobic conditions during germination at College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur. This population was also genotyped using 162 SSR and HvSSR markers. A total of 9 putative QTLs were identified, however, two major QTLs were identified on chromosome 1 and 12 with an LOD of 4.64 and 3.65 between RM3825 to HvSSR187 and RM20 to RM511 markers respectively. The QTLs detected in this study can be further used for MAS (Marker Assisted Selection) based selection for anaerobic germination.

Abstract
The study of entrepreneurship and education of potential entrepreneurs are essential parts of any attempt to a country’s economic well-being. This paper analyses the entrepreneurial capabilities of entrepreneurs engaged in five different forest based business ventures. Entrepreneurial capability and Entrepreneurial Marketing orientation of the selected micro forest entrepreneurs (entrepreneurs engaged in forestry related business) is found to be at moderate level. In case of entrepreneurial capabilities, synchronization was found to be at satisfactory level among the sample entrepreneurs. In case of entrepreneurial marketing orientation, the selected forest entrepreneurs should develop more responsiveness to market intelligence by means of focussing more on customer orientation than on traditional marketing

Abstract
The advantages of fine silk- better reel ability, less size deviation and lousiness and more tenacity and elongation along with cohesion has made the production of high grade silk fabrics, surgical threads, high grade sieves etc. possible. The present study was carried out keeping in view the potentiality of export earnings of such superior silk fabrics and commodities. Out of twenty six genotypes studied seven genotypes revealed thin denier and longer unbreakable filament length. Their performance in other important commercial traits like single cocoon weight, single shell weight, shell ratio, cocoon yield/10,000 larvae by number and raw silk recovery percent were comparable with two highly productive and authorized breeds namely, SKAU-R-1 and SKAU-R-6 in both spring and summer seasons. The breeds may be used for the development of super-fine denier hybrids.

Abstract
Effect of long term fertilizer application with continuous sorghum-sunflower cropping system on nitrogen and phosphorus uptake by sorghum and soil N and P inorganic fractions was studied in the 16th year. Application of 100% NPK + FYM resulted in higher grain yield (32.96 q ha-1) total nitrogen and phosphorus uptake by the sorghum crop ranged from 15.87 and 0.8 kg ha-1 in control to 78.37 and 24.84 kg ha-1 in NPK + FYM. Application of FYM along with NPK resulted in higher NH4–N (28 mg kg-1), NO3-N (19.7 mg kg-1) and phosphorus fractions soloid P (9.6 mg kg-1), Al-P ( 13.8 mg kg-1), Fe-P (30.4 mg kg-1), occluded P (5.4 mg kg-1), Ca-P (40.4 mg kg-1) and tatal P (155.2 mg kg-1) than application of only NPK. Application of crop residues along with NPK also increased the crop yield, nitrogen and phosphorus uptake and soil N and P fractions bringing out the superiority of integrated nutrient management over only fertilizer application

Abstract
Seven representative soil pedons were evaluated for their suitability to high altitude barley cultivation in cold arid high altitude of Ladakh, using limitation method regarding number and intensity of limitations. The soils of the studied area were highly alkaline in nature, low CEC and high base saturation with sodium; calcium as the dominant cations. The study suggests that barley is moderately suitable in soils of Pedon 1 and Pedon 6 Whereas, marginally suitable in soils of Pedon P2, P3, P4, P5 and Pedon P7. None of the soils of Pedons are not suitable for barley cultivation. Soil pH, texture and depth are the major limitations for crop growth in the most of soils of cold arid region. Results showed that the suitability classes can be improved further if the correctable limitations (soil reaction) are altered through soil amelioration measures.

Abstract
For the study of fruit borer infestation during green and mature stage of tamarind pods, two blocks were selected viz. Jagdalpur and Tokapal. For the estimation of losses eight trees were selected randomly in each selected villages of each blocks. Observation on fruit borer infestation during green stage of the pods was started from the month of July to first week of January and remaining observation during mature stage of the pod started from second week of January to second week of March. Mean fruit borer infestation recorded during green and mature stages of the tamarind pod at Jagdalpur and Tokapal block during kharif–rabi, 2015-16. At Jagdalpur block, mean fruit borer infestation of five villages indicated that the highest fruit borer infestation (24.93%) was recorded at green stage of the tamarind pod. At Tokapal block, mean fruit borer infestation of five villages revealed that the level of fruit borer infestation also recorded highest with 20.78 per cent at green stage of tamarind pod. The present investigation concluded that green stage of the tamarind pod was more susceptible to receive maximum losses due to tenderness of the whole pod. However, mature pods are hardy and difficult to bore it resulting less infestation occurred

Abstract
Livestock is an integral part of the production system in the sub mountainous zone of Punjab, India. The present study highlights different constraints perceived by farmers of the zone in livestock management. The primary data collected from 240 respondents proportionately distributed over three land holding categories namely small (<5 acre), medium (5-10 acres) and large (>10 acres), from six blocks of Hoshiarpur and Roopnagar district representing the zone, represents the basis of study. Thebiotic constraints were got ranked by the respondents into low, moderate and high according to perceived intensity. These were assigned values from one to three and depending upon the responses mean score was calculated so as to provide ranks to these constraints. Non availability of high quality breeding bulls, high cost of treatment, incidence of reproductive problems, high cost of feed and fodder, poor extension and health care facilities, problem of disposal of unproductive animals and poor connectivity to the market were found to be the major constraints in the livestock production by the farmers of the sub mountainous zone of the state, the findings of the study call for concerted policy action for the redressal of these constraints

Abstract
This paper attempts explain about innovative agricultural marketing practices adopted in the regulated markets of Karnataka state. The study was based on primary data, obtained through personal interview method using well-structured and pre-tested schedule. The study revealed that considerable number of farmers who sold in premises of interior markets and border markets felt that ICT application was a cheaper source of information, improved their social status, made them knowledgeable and created employment opportunities. The farmers were not satisfied with the innovative practices adopted in the market in terms of technology like internet and kiosk system, because a large number of farmers could not make best use of the technology due to their computer illiteracy. Maximum number of the farmers used Television as the main source of market information for its accuracy, timeliness and content in all interior and border markets because it is accurate and cheap source of information to the farmers.

Abstract
Nine agro-wastes including the paddy straw were evaluated for their influence on yield and yield attributing parameters of Pleurotus pulmonarius. Varying performance was observed among the substrates in respect of days to spawn run and fruit harvest, average weight of sporophores and biological efficiency. The conventionally used substrate, paddy straw was found superior among the substrates in terms of fruit yield (99.30%) followed by maize stalk (92.25%), maize cob (91.93%), green gram stick (88.27%) and paddy husk (80.27%). Sugarcane bagasse, coconut coir, rice bran and saw dusts were proved to be the poor yielders with 61.07, 64.37, 70.20 and 77.40% biological efficiency. Superiority of paddy straw was established in terms of days to spawn run (16.33), days to first harvest (21.33) and average weight of fruit bodies (10.71 g) among the substrates. Among the spawning methods followed, both layer spawning and through mixing ones were statistically at par yielding 97.66 and 96.87% biological efficiency. However, the top spawning method was inferior in terms of yield (78.37%). It was further observed that the yields obtained out of both uncovered bags (97.34%) and the bags with 1.0 cm holes (96.47%) were statistically at par with one another. Moreover, bags with smaller holes were comparatively poor yielders (91.68%).

Abstract
A field experiment was carried out during 2015-16 and 2016-17 at the Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur. Fifteen treatment combinations (viz. five tillage practices and three weed management) were tested in split plot design with three replications to assess the productivity of rice under rice –maize cropping system. The result exhibited that both tillage and weed management had significant influence on yield attributes and yield of rice during both the years. Among tillage practices CT (TPR) – CT i.e. conventional tillage transplanted rice with conventional tillage in rice and conventional tillage in maize resulted in the maximum number of effective tillers (406.5 m2) coupled with highest length of panicle (21.91cm) with more number of filled grains per panicle (116.54) and higher test weight (30.00 g) in highest grain yield (4.45 t ha-1) straw yield (5.88 t ha-1) and harvest index (42.44%) which was comparable with transplanted rice with conventional tillage-zero tillage in maize and these were significantly superior over direct sown rice under both tillage system. Among weed management treatments, application of oxadiargyl 90g ha-1 PE fb pinoxsulam 22.5g ha-1 PoE recorded the maximum values of effective tillers (335.6 m2), panicle length (22.81cm), filled grains per panicle tiller (123.33) test weight (30.56 g) which consequently resulted in highest grain yield (4.98 t ha-1), straw yield (6.16 t ha-1) and harvest index (44.57%) being significantly superior over other weed management practices.

Abstract
The present study was conducted during kharif season of the year 2014-15 at Department of Vegetable Science, College of Agriculture, OUAT, Bhubaneswar, India, to evaluate the nature and magnitude of genetic divergence in 23 bitter gourd genotypes. Results revealed the presence of wide genetic diversity. The genotypes were grouped into 7 clusters based on Mahalanobis D2 statistics using Tocher's method. The clustering pattern of genotypes revealed that the genetic diversity was independent of the geographical diversity. Among the 7 clusters, maximum numbers of genotypes were found in cluster VII, followed by Clusters-I, III and VI with 3 genotypes each. Clusters-IV and V comprised two genotypes each. Among the 15 quantitative characters studied, the maximum contribution towards divergence was made by seed/flesh ratio (22.529%) followed by yield per plant (20.946%) and fruit weight (16.996%). Maximum inter-cluster distance was observed in Cluster VI and VII (D2 = 437.461), followed by Cluster IV and VII (D2 = 322.148) and Cluster II and VII (D2 = 314.431) and Cluster III and VII (D2 = 312.473). Intra-cluster distance was highest in Cluster VI.

Abstract
The present study was conducted in the Experimental Farm of Department of Vegetable Science at Dr. Y. S. Parmar University of Horticulture and Forestry, Solan during Kharif season of 2014-2015. Fifty six genotypes collected from different agro-ecological conditions were exposed to principal component analysis for fourteen traits to determine the variability source structure. The results revealed that, 95% of the total variability present among all the genotypes of tomato is explained by the first ten principal components (PC) but out of fourteen, the first five component axes in the principal component analysis had Eigen values up to 1.0 and above, presenting cumulative variance of 76.64%. The first PC explained characters like number of fruits per cluster, number of fruits per plant, plant height, internodal distance and harvest duration which are positively related with yield while days to first picking observed to have negative effect on yield and it was cleared from the values of PC1. Characters like average fruit weight, yield per plant, pericarp thickness and locular wall thickness were observed in PC2 whereas, traits like number of locules per fruit, total soluble solids and lycopene content were explained by PC3, PC4 and PC5 respectively. Therefore, the above-mentioned variables might be taken into consideration for effective selection of parents during hybridization program for broadening the genetic base in the population as well as to develop elite lines.

Abstract
A study was conducted to investigate the possibility of exploiting heterosis in breeding for improved quality in forage sorghum [Sorghum bicolor (L.) Moench]. Hybrids and parents were evaluated at two locations with two dates of sowing during the kharif season of 2015-16. Data on five randomly taken plants from each genotype in each replication were recorded on different quality characters in all the four environments at first cut (55 days after sowing) and second cut (45 days after first cut). Low HCN is desirable and hence the cross combinations having negative heterosis for low HCN were desirable. Cross 31A × IS 2389 (-48.84%) in E1 recorded highest heterosis in negative direction for HCN content followed by 56A × IS 2389 (-41.18%) in E4, 9A × HJ 541 (-38.85%) in E4 with check SSG 59-3. On the other hand, hybrids 31A × IS 2389 (-39.97%) in E4 with check MFSH 4 showed maximum heterosis for HCN content and 56A × IS 2389 (-30.98%) in E3 with check SSG 59-3. It was concluded that exploiting heterosis in forage sorghum to improve quality traits might be promising.

Abstract
Floods have been recurrent phenomena in India from time immemorial. Almost every year floods of varying magnitude affect some parts of the country or the other. These floods result in serious reductions in agricultural production which in turn have a depressing effect on the economy. Floods at the initial stage affected public infrastructures of worth 2889.75 lakhs, among public roads were affected to the maximum. In the next stage, flood affected physical structures that were maintained by farmers among dwelling houses were affected most. Agriculture was the means of farmers livelihood in study area wherein flood also affected farmers to the maximum extent. In kharif season, farmers witnessed for a greater overall net loss of about 74.00 per cent (Rs.1,81,033), in Rabi about 85 per cent (Rs. 1,00,320). Government can also think of dispensing loan for livestock with less or no interest to the affected land less labours and small farmers, whose livelihood is dependent on the which enable them to earn their bread and butter easily after the disaster.

Abstract
An experiment was carried out to study the effect of fertigation and foliar nutrition on yield and yield attributes in banana under precision farming for two consecutive seasons in the College of Agriculture, Kerala. The experiment was laid out in split plot design with six main plots and three sub plots replicated thrice. Fertigation treatments with different fertilizers at 60 per cent of the recommended dose and soil application of full dose of nutrients with basin and drip irrigation were allotted to main plots. Foliar nutrition included foliar spray of 19-19-19, bunch spray of Sulphate of Potash (SOP) and water spray. The study showed that fertigation of 60 per cent N and K as urea and Muriate of Potash (MOP) along with the soil application of full P as rock phosphate (n4) and fertigation of 60 per cent RDN as combination of 10-10-10, urea and SOP (n5) produced a comparable yield with soil application of full dose of nutrients with drip and basin irrigation. Moreover, spraying with SOP in the bunches @ 2% after complete bunch emergence and three weeks after first application significantly improved yield and yield attributing parameters except number of hands bunch-1. From the results, it could be concluded that fertigation with 60 per cent N and K as urea and MOP and soil application of full P as rock phosphate along with foliar application of 19-19-19 at 2, 4 and 6 MAP or bunch spray of SOP were effective in improving the yield.

Abstract
Weed infestation in mungbeans is one of the chief production concerns, having short stature plant morphology. In this study different options for weed management in mungbean were tried during kharif 2013 and 2014. The experiment was conducted at Dryland Agriculture Research Station of Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir. Two manual hand weeding at 20 and 35 days after sowing (DAS) was found significantly superior in yield attributes and seed yield but was at par to pre-emergence application of pendimethalin + imazethaper @ 0.75 kg/ha pre-emergence (PE) followed by one hand weeding at 35 DAS. Further it was found that, pendimethalin + imazethaper @ 0.75 kg/ha-PE followed by one hand weeding at 35 DAS recoded higher yield attributing characters and seed yield. The gross returns were higher with two manual weeding, however the benefit cost ratio (B:C) was higher with application of pendimethalin + imazethaper @ 0.75 kg/ha PE followed by one hand weeding at 35 DAS.

Abstract
Twelve okra genotypes were evaluated for their stability, with respect to yield and its contributing traits, in four different locations. The pooled analysis of variance revealed significant difference among the genotypes and environments for all the characters, indicating that genotypes and environments tested are diverse in nature. Genotype × environment interaction was significant for all the characters suggesting genotypes interacted significantly with environments. Hybrids viz. Thirumala local x Mallapalli local and Thirumala local x Kattakada local were identified as stable hybrids for yield along with other yield contributing characters like fruit weight and number of fruits per plant. While, Holavanalli local x Mallapalli local were identified as suitable for favourable environments with regard to yield, fruit length, fruit girth, number of fruits per plant and duration. The hybrid Thirumala local x Punjab Phalgani was observed suitable for poor environments for characters like days to first flowering, fruit weight, yield per plant and plant height.

Abstract
This study was designed to evaluate the oxalic acid treatments affectivity on ber fruit cv. ‘Gola’ regarding fruit quality. Prior to storage fruits were subjected to 10 min dipping in aqueous solution of oxalic acid at different concentrations (2 mM, 4 mM, 6 mM, 8 mM and 10 mM). Fruit firmness, respiration rate, ethylene evolution rate, polygalacturonase (PG) and pectin methylesterase (PME) were measured. The results revealed by dipped for 10 min at ambient temperature with 10 mM oxalic acid, the respiration rate and ethylene evolution rate was initially increased up to 5th day and then decreased. The application of oxalic acid reduced respiration rate and ethylene evolution rate and delayed softening of ber fruit. During the storage, the firmness showed a decreasing trend throughout the storage period. The inhibition of softening was associated with decreased PG and PME activities; that is, the retardation of pectin solubilization /degradation. It was suggested that 10 mM oxalic acid is beneficial in extending the shelf life up to 9 days at room temperature, and maintaining quality parameters by maintaining physiology and enzymatic activity of ber fruits.

Abstract
Biopesticides are non toxic to human, less expensive and safe for the environment. Hence research was undertaken to compare and evaluate the bio efficacy of different bioagents like Trichodermaviride, Pochoniachlamydosporia, Pseudomonas fluorescensand Paecilomyces lilacinusby soil application either alone or combined with T. viride or P. fluorescens. The results indicated that all these bioinoculants (Paecilomyces lilacinus) either alone (50g/m2) or in combination (25g each/m2) with T. viride or P. fluorescens significantly increased the plant momrphometric parameters i.e. shoot height, fresh and dry weight of shoot, root length, fresh and dry weight of roots. However maximum increase in these parameter was recorded in T7 followed by T5. The number of galls per plant, number of egg masses per plant and final nematode population in soil as well as in root reduced in soil application of Carbofuran used as chemical check (T10) closely followed by soil application of T. Viride + P. lilacinum which were statistically at par. The rate of nematode multiplication was minimum 0.96 times in T7 as against 2.11 times in T11 (Untreated control). Application of chemical nematicide was uneconomic, unsafe, toxic to human and beneficial microorganisms so use of biocontrol agents i.e. soil application of T. Viride + P. lilacinum @ 25g/m2 each was the alternate strategy for management of root knot nematode, M. incognita in tomato
