Abstract
Brassica carinata commonly known as Abyssinian mustard or Ethiopian mustard is currently being evaluated as an option to the traditional canola/mustard cultivation especially for low rainfall areas of the world. In its home land it is higher yielding, has better resistance to diseases, insect pests and pod shattering than any other oil seed crop. In spite of these strong positive attributes, the crop suffers from several agronomic limitations like late maturity, susceptible to lodging, low seed yield, low oil quality characterized by high level of erucic acid and unacceptable level of meal glucosinolates. Restricted level of natural variability for specified traits has greatly constrained the breeding programmes aimed at overcoming these limitations. Interspecific hybridization involving elite lines of related digenomic species viz Brassica napus and Brassica juncea species can serve a potential and useful method for transferring valuable traits to Brassica carinata in future although least research has been done on this aspect.

Abstract
Field experiments were conducted on sandy clay loam soil of Agricultural College Farm, Bapatla during kharif to study the effect of different levels of nitrogen and phosphorus on rice (Cv BPT-5204) growth, yield and nutrient uptake. The treatments consisted of four nitrogen levels i e 80 kg N ha-1, 120 kg N ha-1, 240 kg N ha-1, green manuring @ 5 t ha-1 and three phosphorus levels i e 0, 30 and 60 kg P2O5 ha-1. Among different treatments, application of 240 kg N ha-1 in combination with 60 kg P2O5 ha-1 significantly increased the plant height, tiller number, drymatter accumulation, grain, straw yield and nutrient uptake of rice over other levels of nitrogen and phosphorus. However, it was on a par with that of application of 240 kg N in combination with 30 kg P2O5 ha-1 during both the years of the experimentation.

Abstract
The experimental was conducted in Department of Genetics and Plant Breeding, Indira Gandhi Krishi Vishwavidhyalaya, Raipur (Chhattisgarh) laid out in a randomized complete block design with three replications during rabi 2012-13 and 2013-14. Nature and magnitude of genetic divergence was assessed among three seed classes (Certified, Breeder, Mixture) of four popular varieties (Deepika, Indira Alsi-32, RLC-92, R552) of linseed using Mahalanobis's D2 statistic for fifteen quantitative characters. On the basis of D2 values, 3 seed classes of 4 linseed varieties were grouped into 3 clusters. The cluster I was the largest cluster consisting of 6 seed classes while cluster II and III contained 3 seed classes each. Among the different characters, days to 50 percent flowering, days to maturity and seed yield per plant played an important role in the formation of clusters. The cluster I showed maximum inter cluster distance with cluster IV. The varieties from these clusters may be used for quality seed production and future hybridization programme.

Abstract
A field experiment was conducted during 2013 and 2014 at a Farmer’s Field in Perambalur District, Tamil Nadu, India, to study the interaction effect of organic manuring and weed control measures on weed growth and yield of irrigated hybrid maize NK 6240. The experiment was laid in a split plot design with three replications. Among the main treatments tried, application of poultry manure @ 5 t ha-1 was found to be superior in reducing the population of weeds (19.40 m-2) and in increasing weed control index (65.93%) and grain yield (6.10 t ha-1) in both the seasons. This was on par with the application goat manure @ 5 t ha-1. Among the crop weed control measures compared as sub-treatments, twice hand weeding recorded the least weed counts (11.00 m-2) and highest WCI (85.80%) and grain yield (7.35 t ha-1). This was observed to be on par with the application of pre-emergence herbicide atrazine @ 1.00 kg a.i ha-1 + post emergence herbicide 2,4-D @ 0.80 kg a.i. ha-1 (weed counts of 14.00 m-2, weed control index of 84.04% and grain yield of 7.23 t ha-1). Post emergence application of tembotrione + S 120 g a.i. ha-1 along with surfactant was found most effective to control the grassy as well as non-grassy weeds which was also on par with hand weeding twice in reducing the weed count (15.60 m-2) and increasing WCI (82.57%) and grain yield (7.18 t ha-1) in hybrid maize.

Abstract
Strawberry is a good source of vitamin, mineral and antioxidant compound. As the demand of strawberry is increasing day by day and supply is limited, one of the possible ways to narrow down this gap between demand and supply could be utilization of tissue culture approaches. The production of strawberry through micropropagation becomes a relevant issue throughout the world. Mass multiplication of this cultivar has a serious problem of high mortality due to lethal browning of plantlets on the growing MS media. Therefore, the objective of this study was to control the browning and optimized the media components for the mass multiplication of strawberry plants using shoot apex, nodal stem and leaf segment. Explants were pre-treated with mixture solution having 0.1% streptomycin and 0.1% bavastin followed by serial transfer of the explants for 48 hour of time interval thrice in MS media, minimum browning were observed in the explants with 48 hours of serial transfer and maximum propagation of plantlets from medium M4 having concentration 1.5 mg/l BAP and 0.5 mg/l KIN with high number of shoot apex as compared to other media. Further, elongated shoots on M4 medium have been excised and transferred to root induction media having different concentration of IBA (0.1 to 2 mg/l) and IAA (0.1 to 2 mg/l) of which 1.7 mg/l IBA proved to be the most suitable for root induction and rooted plantlets after 20 days were hardened to pot mix for maturation.

Abstract
investigate the effect of phosphorus supply on morpho physiology aspects in different rice varieties a pot culture study was conducted. Phosphorus (P) deficiency led to a significant reduction in plant height and tiller number among the rice varieties which are considered as sensitive parameters to P deficiency. Lesser reduction in plant height and a higher tiller number was evident in Swarna indicating its tolerant nature. Irrespective of the varieties, under P stress the days to 50% flowering and days to maturity were enhanced. The chlorophyll and carotenoid contents were generally increased at lower level of P while at the higher P level the chlorophyll contents were decreased among all of the varieties.

Abstract
The effectiveness of Minimum Support Price (MSP) has been examined in different regions of Karnataka based on the secondary data from respective markets at district level spanning from 2002-03 to 2012-13. The deviations of market prices from MSP have been used as a measure of ineffectiveness. The CAGR of MSP was found to be inequitable for all crops i e cotton (6.27%), redgram (11%) and paddy (9.21%). The percentage change in MSP was positive for all the crops which are taken for the study. The CAGR of market price of major crops in Gulbarga and Raichur market was high in redgram (11.43%) and jowar (14.39%). MSP was leading the trends in market price of all the major crops in Raichur market but not in Gulbarga. The total frequency of months with positive deviations of market price from MSP were more than the frequency of months negative deviations for all the crops under study in both the study markets. There is need to bring some improvement in the price policy to different crops in ensuring highest returns to the farmers to continue their production with the increase in cost of inputs.

Abstract
Blast disease of finger millet caused by Pyricularia grisea (Cooke) Sacc. (Magnaporthe grisea) causes significant yield loss in different regions of India. This study was conducted to collect, isolate, identify and characterize the pathogen using morphological characteristics. A total of 41 isolates were collected from different millet growing regions of India viz Bengaluru, Mandya, Vizianagaram and Shillong. Morphological variability of different isolates in culture on RYLA showed considerable variations in mycelia growth, colour, conidia production and conidial shape and size. Among the different isolates, while the colony diameter ranged from 7.0 to 8.8 cm, all the isolates produced grayish black to whitish black and whitish to buff colour with circular and irregular colonies having rough and smooth margins. Most of the isolates sporulated well on RYLA and took 7-12 days. The conidia were pyriform (pear-shaped); either large, medium to small in size having rounded base and the pedicel narrowed towards the pointed tip. Variations in conidial size were also evident between the isolates and different locations. Isolation and variability studies on finger millet blast pathogen helps to understand requirements for the growth and development of the pathogen and its sporulation which can be made use of in understanding variability of the blast pathogen.

The treatments were comprised 36 treatment combinations with four factors viz date of sowing [D1-22/06/10 (25th MW)], [D2-29/06/10 (26th MW)], [D3-06/07/10 (27th MW)], [D4-13/07/10 (28th MW)], [D5-20/07/10 (29th MW)] and [D6-27/07/10 (30th MW)], variety (V1-NHH-44, V2-NHH-44 Bt, V3-NH-615) and plant protection (P1-Recommended spraying schedule) and no plant protection (P0-control). The crop was sown with row to row and plant to plant spacing 90cm x 60cm by dibbling method in 06 different meteorological weeks. Each experimental unit was replicated thrice with the plot size of 7.2 m x 3.6 m and 6.0 m x 2.4 m as the gross and net plot, respectively. Fertilizers were applied to the crop as per the recommendations. The result revealed that the sowing of cultivar NHH-44 with D1 date [(22/06/10 25th MW)] cotton performed better growth and development characters as compare to other cotton cultivars. Based on these findings it can recommended for farmers that optimum sowing time for cotton in Marathawada region under rainfed condition is D1 (25th MW) just at the onset of monsoon.

Abstract
The study was undertaken in the Krishna western delta to compute the water balance for the year 2011. The gross annual groundwater recharge for the year 2011 is 170086 ha m, net ground water recharge 1695024 ha m and the total ground water table fluctuation 0.34 are estimated from this study. Variation in the net ground water recharge is due to the low rainfall (660 mm) in the year 2011 and more evapotranspiration (3269.8 mm). The assumption, inflow is equal to outflow made by CGWB for estimation of groundwater potential is a deviation from reality as some blocks have shown net inflow or outflow. From this study high ET is observed compared with the rainfall except in the months of April, June, July and August. Due to low rainfall over-pumping of groundwater by farmers has led to underground resources becoming depleted.

Abstract
The study was undertaken in Chikkaballapura district of Karnataka state during the year 2012-13. Four major reeling units viz Charaka, Cottage basin, Filature basin and Multi-end basin were identified based on preliminary survey in the study area. The study based on primary data from 90 reelers covering a proportionate sample of 60 reelers under Charaka, 3, 22 and 5 reelers from Cottage basin, Filature basin and Multi-end basin respectively was elicited for the period 2012-13 through survey method. The data was analyzed using tabular analysis, cost-return structure and simple financial analysis. Results revealed that the share of building cost in total establishment cost was found to be relatively higher in Charaka and Cottage basin than Filature basin and Multi-end basin, since in later case cost of reeling basins was high. Raw silk reeled per basin per year is least in Charaka (661.44 kg’s) and higher in Multi-end (859.13 kg’s). Net returns per basin per year realized is least in Charaka (₹ 54,546) and higher in Multi-end (₹ 3,05,405). The benefit-cost ratio worked out to be low in Charaka (1.20) and high in Multi-end (1.04). Multi-end basin was found to be efficient from the view of Renditta.

Abstract
Seed quality is influenced by fruit size and position of seeds within the fruit. In Snake gourd variety “Baby”, large sized fruits recorded higher number of seeds (65.10) and 100 seed weight (28.72 g) than medium and small fruits. However, seed quality parameters viz germination per cent (80%), seedling length (23.00 cm) and vigour index (1842) were found to be high in seeds obtained from medium sized fruits when compared to large and small sized fruits. Studies on influence of seed position on fruit and seed characters showed variations. The middle region of small, medium and large sized fruits recorded significantly higher fruit weight (121.67g, 200.00g and 269.17g, respectively) compared to stylar region and pedicel region in Baby. Seed number and 100 seed weight was found to be highest in the middle region of fruits followed by stylar region and pedicel region. The germination percent, speed of germination, seedling length and vigour index of seedlings obtained from different regions of different sized fruits were found to be significantly different. Seeds of the middle region of different sized fruits (small, medium and large) recorded significantly higher germination percent (80, 84 and 83), speed of germination (8.74, 10.31 and 9.37), seedling length (21.95 cm, 23.62 cm and 23.12 cm) and vigour index of seedlings (1758, 1986 and 1910) followed by seeds of stylar region and pedicel region.

Abstract
Sericulture involves a series of activities from mulberry leaf production to silk and earning livelihoods for rural mass as well other dependents. The national level policies like an import duty reduction on silk reduce the cocoon prices at the local market, which in term worsens the situation of farmers. Recent changes in macro policies have evident that within a span of a week the cocoon prices were halved in local markets. Karnataka being the major producer of mulberry silk the changes in the area as well production of traditional belt and non-traditional belt were analyzed over a period of 10 years using CAGR. Results have shown that the area under mulberry is being reduced and negatively growing both in traditional (-4.09) as well non-traditional belt (-3.7). The cocoon production has recorded negative growth in non-traditional (-5.7) where as it has seen a meager positive growth in traditional (0.027) belt because of differences in productivity.

Abstract
A study was conducted to test the nematicidal activities of bioactive molecules of Ophiocordyceps sinensis (Berk) G. H. Sung et al. and O. neovolkiana (Kobayasi) G. H. Sung et al. against root knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood. The experimental results revealed that the lowest egg hatching and the highest juvenile mortality were recorded with the methanolic extract of cell free culture (CFC) filtrate of O. sinensis followed by its mycelial extract and CFC filtrate of O. neovolkiana. At 1000 ppm concentration, the concoction of bioactive molecules of O. sinensis exhibited the maximum inhibition of egg hatching (94%) and juvenile mortality (92%) of M. Incognita at 72 hours of incubation. The comparative efficacy at 50 ppm was found to be on par with that of the recommended dose of carbofuran used at 15 ppm. Analytical estimates indicate the presence of increased levels of phenolic compounds in the methanolic extract of CFC filtrate and mycelium of O. sinensis and O. neovolkiana. GC-MS of CFC filtrate of O. sinensis exhibited the presence of 2-tert-Butyl-4-isopropyl-5-methylphenol, which might be responsible for the antinemic property against M. Incognita.

Abstract
Ex post facto research design was adopted in the present investigation. Karimnagar district of Telangana region of Andhra Pradesh state was purposively selected for the study as maximum budget is allotted by the Department of Agriculture, Government of Andhra Pradesh for this district among the other Telangana districts under farm mechanization. The study was conducted in 4 villages selected from 2 mandals of Karimnagar district, which included 30 farmers from each of the selected village, thus a sample of 120 farmers were selected for the study. The study clearly revealed that two farmer innovations and two modifications were documented in the study area. Difficulties in operating original implements, labour problems, non availability of original implements etc were found to be the important reasons expressed by innovators for innovating or modifying the implements. It is distressful to note that none of these farmer innovators made any efforts to disseminate these innovations to mass media. In spite of this, few farmers of surrounding villages who visited the innovator farm have adopted these innovations in their fields also. Efforts should be made by NGO’s and department of agriculture to identify such farmer innovators. They should be encouraged by announcing awards and rewards. These farmer innovations should be multiplied and disseminated by extension personnel.

Abstract
Field experiments were conducted to study the nature and magnitude of genetic diversity among twenty three genotypes of rice following the Mahalonobis D2 statistics. The genotypes were grouped into seven clusters. Cluster III had the highest genotypes (8) followed by cluster I and V (4). The genotypes falling in cluster III (36.11) had the maximum divergence which was followed by cluster I (26.53) and cluster V (26.42). The inter cluster distance ranged from 15.20 to 122.00 as exhibited between cluster II and VI and cluster IV and VII, respectively. In the present study, parental lines selected from cluster IV recorded earliness in flowering and may serve as a suitable source for incorporation of earliness in other genotypes.

Abstract
The present study which consisted fifteen determinate genotypes of tomato, which was laid out in randomized block design with three replications during rabi season 2012-2013 at Research cum Horticulture Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). Genotypic correlation coefficients were greater than phenotypic correlation coefficients for most of the characters indicating strong inherent association between the various characters the traits. The coefficient of correlation of yield was found to be positive and significant with days to 50% flowering, number of primary branches per plant, number of secondary branches per plant, number of calyx per fruit, number of fruits per plant and fruit weight per plant. Path coefficient analysis revealed that the fruit yield per plot, fruit weight per plant, number of calyx per fruit, number of locules per fruit, fruit length, days to 50% flowering, pericarp thickness, number of secondary branches, plant height, fruit weight, number of fruits per plant, acidity and 1000 seed weight seem to be the major yield contributing traits in tomato.

Abstract
A field experiment was conducted at the Research Farm of the College of Agriculture, Nagpur during kharif season 2013 to study the efficacy of different post- emergence herbicides on weed management in soybean (Glycine max L.) grown on clayey soil. The treatment of two hand weedings at 15 DAS and 30 DAS being at par with the application of imazethapyr + Imazamox @ 43 g a i ha-1 at 10 DAS and Imazethapyr @ 75 g a i ha-1 at 10 DAS. These treatments were found more effective in controlling weeds throughout crop growth period and improving growth characters viz plant height, number of branches plant-1 and plant dry matter (g) significantly over rest of the treatments under study. Highest grain yield were obtained two hand weedings at 15 DAS and 30 DAS which were at par with the application of imazethapyr + Imazamox @ 43 g a i ha-1 at 10 DAS and Imazethapyr @ 75 g a i ha-1 at 10 DAS.

Abstract
The present study which consisted fifteen determinate genotypes of tomato, which was laid out in randomized block design with three replications during rabi season 2012-2013 at Research cum Horticulture Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). Analysis of variance indicated that the mean sum of squares due to genotypes were highly significant for all the characters. The high phenotypic and genotypic coefficients of variation were observed for number of secondary branches per plant, fruit yield per hectare, fruit yield per plot, numbers of fruits per plant, number of primary branches per plant, numbers of locules per fruit. High values of heritability coupled with high genetic advance as percentage of mean were observed for fruit weight, number of locules per plant, acidity, number of primary branches per plant, plant height number of secondary branches per plant, number of fruits per plant and fruit yield per plot.

Abstract
A laboratory experiment was conducted for developing a protocol, separation of compounds by chromatographic technique and screening antimicrobial compounds from selected medicinal plants; Lantana and Eupatorium. Antimicrobial compounds from these plants were screened for their antimicrobial activity against four bacteria and two test fungi. Plants were extracted with different polar (ethanol and ether) and non-polar (chloroform and hexane) solvents. TLC profiling of the plant extracts in different solvent system indicated the presence of different groups of phytochemicals in them. Terpenes, phenolic acids and flavonoid compounds were effective in inhibiting the growth of microorganisms. Compounds from plant extracts showed highest activity against plant pathogens tested. Ethanol solvent was found to be better solvent for purifying the compounds followed by the solvent chloroform.

Abstract
A survey was conducted in the areca growing tracts of Davangere districts to assess the status of available nitrogen, phosphorus, potassium, sulphur and exchangeable calcium and magnesium in soils. The samples were belongs to sandy clay loam to sandy clay loam in texture, sand was dominant fraction in surface soils as well as sub-surface soils and the clay showed an increasing trend with the depth. The soils were neutral to alkaline in reaction with low EC and medium to higher content of organic carbon. Available nutrient status of nitrogen, potassium, sulphur were ranged between medium to high, phosphorus was ranged between low to high. Exchangeable calcium and magnesium were recorded higher than the critical limits.

Abstract
The lower productivity of rice under jhum was due to non adoption of improved agronomic practices as efficient rain water management, no improved varieties, no intercultural operation as weeding, improper sowing, and no taking up sound plant protection measures. The improvement in the productivity level of upland jhum paddy can be improved to a greater extent by making suitable intervention in the existing practices. Among the interventions required in this regards are proper land preparation, seed and sowing including seed priming, participatory breeding work to improve the local strains of upland paddy, suitable blend of traditional knowledge and frontier technologies for eco-friendly low cost pest management. Among all these rice production methods in North east India, large no of farmers were adopted Jhum rice cultivation (1275) followed by paddy cultivation in terrace (859) and Panikheti production system (835). Area coverage also more in paddy cultivation in terrace (401) followed by Jhum rice cultivation (381) and Panikheti production system (276) while in terms of productivity paddy cum fish culture (4.28 t/ha) was most dominant among all production methods followed by paddy cultivation in terrace (4.14 t/ha) and Panikheti production system (3.96). Out of five different methods of rice cultivation paddy cum fish culture was the best method of cultivation followed by paddy cultivation in terrace and Panikheti rice production system. Among all improved varieties, Bhalum 1, Bhalum 2, Bhalum 3 and Bhalum 4 was most early maturing varieties while among in insect pest and disease management point of view RC Maniphou 4, RC Maniphou 5, RC Maniphou 6, RC Maniphou 7 and RC Maniphou 11 was the most important varieties. Among all varieties, RC Maniphou serious was most dominant followed by Lung nilaphou, NEH Megha Rice and Bhalum series.

Abstract
The present study was carried out to examine the economics of system of rice intensification (SRI) and conventional method of rice cultivation in Karaikal district of Puducherry based on a total sample size of 65 farmers. The difference in cost of cultivation between these two methods is found to be almost negligible. The benefits of cost reduction in SRI method were not realized by the farmers following SRI method. Indeed the SRI method of rice cultivation showed its superiority through higher yield than conventional method was found from the study. From the present study it was found that there is higher net return in SRI over conventional method of rice cultivation. The study reveals the superiority in terms of economics in SRI method over conventional method of rice cultivation. There is possibility for farmers following SRI method can get higher benefits by reducing cost of cultivation using inputs efficiently. As the SRI method is newer to the farmers it may took some time period and needed more experience to attain higher benefits.

Abstract
An investigation was conducted to study the effect of 4 levels of castor cake (0, 4, 6 and 8 t ha-1) and 4 levels of nitrogen (0, 50%, 75% and 100% recommended dose of nitrogen). Application of castor cake at 8 t ha-1 and nitrogen at 100 percent recommended dose recorded significantly higher bulb length, bulb diameter, bulb weight and onion yield over rest of the treatments. Further the interaction between different levels of castor cake and nitrogen application revealed that castor cake at 8 t ha-1 in conjunction with 100 percent recommended dose of nitrogen recorded the highest bulb yield and was found on par with castor cake at 6 t ha-1 combined with 100 percent recommended dose of nitrogen and caster cake at 8 t ha-1 combined with 75 percent recommended dose of nitrogen.
