Abstract
The study was conducted at the Main Vegetable Research Station, Anand Agricultural University, Anand during the period kharif-rabi 20010-11 with the objective to determine the effects of different concentrations of GA3 and chemicals on quality and shelf-life of tomato. The experiment consisted of two main factors, factor A with two levels [Breaker stage (S1) and Redripestage (S2)] and factor B with nine treatments [GA3 @ 20 and 40 mg/l; KNO3 @ 2000 and 4000 mg/l; KHCO3 @ 2000 and 4000 mg/l; boric acid @ 100 and 200 mg/l with the control (without spray)]were arranged in 2 × 9 factorial randomized block design with three replications. The quality parameters viz total soluble solid (TSS), physiological loss of weight (PLW), decay or rotting, acidity, lycopene, ascorbic acid and carotenoid content influenced by stages of picking and post-harvest treatments of GA3 and chemicals had significant and positive effect over the control. The fruit harvested at red-ripe stage (S2) exhibited significantly the higher effect on various qualitative parameters. However, significantly the lowest PLW and decay loss were recorded under the fruits harvested at breaker stage (S1) as compared to the red-ripe stage. The post-harvest treatment of GA3 @ 40 mg/l (T2) recorded significantly the highest TSS (4.23 and 4.62%), acidity (1.43 and 0.95%), lycopene (6.40 and 8.75 mg), ascorbic acid (8.52 and 10.05 mg) and carotenoid content (17.33 and 19.25 mg) at initial (after harvest) as well as 6th day of storage, respectively. On the other hand, significantly the lowest PLW (0.18 %) and decay loss (33.47 %) were observed in the treatment T2 (GA3 @ 40 mg/l) and T1 (GA3 @ 20 mg/l) at 12th day of storage, respectively. While, the interaction effect between the harvesting stages (S) and post-harvest treatments (T) had non-significant effects in all the parameters except PLW and decay loss during the storage of tomato fruit cv. Anand Tomato-3.

Abstract
Tests were conducted on two vegetables in 2013 at the Crop Physiology Laboratory, VIA, Pollachi, Tamil Nadu. Experimental materials were arranged in a completely randomized design. The results designated that there were significant differences in seed attributes due to the application of tree leaf extracts. Seeds treated with T5 (Dalbergia oliveri) and T6 (Morinda tinctoria) increased germination percentage, shoot and root length and vigour index significantly in chillies. With respect to tomato the treatments T7 (J. curcas) and T5 can be recommended for improving the physiological characters of seed. Hence, it is recommended that seed treatment with 5% Dalbergia oliveri fresh leaf extract of can be exploited to get good quality seeds/seedlings of tomato and chillies.

Abstract
The study was undertaken in Chikkaballapura district of Karnataka to assess livelihood status, financial viability, employment generation and constraints faced by reelers of various reeling systems. Based on preliminary survey four major reeling units viz charaka, cottage basin, filature basin and multi-end basin were identified. In the study 90 sample respondents were interviewed covering a proportionate sample of 60 reelers under charaka, 3, 22 and 5 reelers from cottage basin, filature basin and multi-end basin, respectively. Results revealed from the study that high investment and high risky technologies like filature basin and multi-end basin were practiced by relatively lower age group entrepreneurs. 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). The employment generation was high in charaka reeling units and reeling is the operation which generates maximum employment irrespective of reeling system. There are many problems faced by the reelers among those, Working capital and labour shortage are the foremost constraints.

Abstract
Twenty two genotypes of kabuli chickpea were evaluated for physicochemical and cooking quality traits. The highest magnitude of genotypic and phenotypic coefficient of variation was found for hydration capacity followed by 100-seed weight (seed size), seed volume, swelling capacity and cooking time. High heritability coupled with high genetic advance was recorded for 100-seed weight, hydration capacity, swelling capacity, seed volume and cooking time. Correlation analysis revealed that the magnitude of genotypic correlation coefficient was higher as compared to their corresponding phenotypic correlation. Seed size exhibited a highly significant positive correlation with hydration capacity, swelling capacity and seed volume at genotypic and phenotypic level. Path coefficient analysis revealed that hydration capacity had the highest positive direct effect on 100-seed weight (seed size) followed by swelling capacity, seed volume, swelling index and cooking time.

Abstract
A field experiment was conducted at the Gwalior (Madhya Pradesh) to study the bio-efficacy of ethanol extracts of four plant materials viz seed of neem, leaf and seed of datura, leaf of harsingar and flower of chrysanthemum in the three concentrations (0.5, 1.0. and 1.5%) and their interaction were tested against Earias vittella under laboratory conditions. The fruits of okra treated with different plant extracts were kept in jar for egg deposition by E. vittella. On the basis of number of eggs laid by the adults, datura extract showed higher ovipositional deterrent effect against E. vittella, followed by neem seed. The higher concentration of all the tested extracts showed higher ovipositional deterrent effect against the pests than their lower concentration. Antifeedant and growth inhibitory index were assessed by offering the treated fruits to five third instar larvae. The amount of unconsumed food and larval weight were recorded after 48 hours. On the basis of antifeedant index, neem seed extract was found the most effective, followed by datura. Chrysanthemum was not found effective significantly, whereas all the tested plant materials showed their growth inhibitory effect against the pest. Higher concentration of extracts showed higher antifeedant and growth inhibitory effect against the pests.

Abstract
Field experiments were conducted for two seasons during 2012-2013 at Hi-Tech-Horticulture unit at Agricultural Research Station, Saidapur, UAS, Dharwad (Karnataka). Three drip irrigation regimes (40, 60 and 80% ETc) were based on accumulated pan evaporation (Epan) and three fertigation levels (50, 75 and 100% RDF) in the form of water soluble fertilizer were laid out in factorial randomized block design and replicated thrice with one absolute control (drip irrigation at 100% ETc and soil application of 100% RDF in the form of conventional fertilizer). The results indicated that, all drip fertigation treatments recorded significantly higher water use efficiency (WUE), fertilizer use efficiency (FUE), N uptake and yield as compared to drip irrigation with soil applied fertilizers. Irrespective of fertigation levels, FUE, N uptake and yield were not affected significantly when there was reduction in drip irrigation from 80 to 60% ETc. Whereas; the lower values for these characters were recorded with 40% ETc. Similarly, the highest WUE, N uptake and yield were recorded by application of 100% RDF through fertigation which was on par with 75% RDF. Whereas the lower values for these characters were recorded with 50% RDF. The treatment combination of 60% ETc through drip plus 75% recommended NPK through fertigation was sufficient to obtain maximum N uptake and yield. In addition, irrigation at 40% ETc resulted in significantly higher WUE followed by 60% ETc, whereas the lowest WUE was recorded with 80% ETc. Similarly, fertigation at 50% RDF recorded significantly higher FUE followed by 75% RDF, whereas the lowest FUE was recorded with application of 100% RDF.

Abstract
Onion which is considered to be a major as well as important crop of our country and showed an excellent view in area, production and productivity. India which is next to china in production point has to necessarily think in increasing its income through exports. Some of the major importing counties are Bangladesh, Malaysia, United Arab Emirates, Sri Lanka and Indonesia. India has too looked over the minor importing countries to be dependent on Indian onions for its consumption. Expansion of area under onion in early kharif, kharif and late kharif may be taken up so that quality onions are available for export on regular basis.

Abstract
A field experiment was conducted during kharif 2012 under irrigated conditions at Agricultural Research Station, Malnoor, Karnataka, to investigate the evaluation of sequential application of herbicides on weed control, growth and yield of maize. The study involves the application of two pre-emergence herbicides atrazine (50 EC), pendimethalin (30 EC) alone and tank mix application and each of these followed by 2, 4-D sodium salt (80 WP), metsulfuron methyl (20 EC) and one hand weeding at 30 DAS. These were compared with farmer’s practice (IC at 20 DAS + HW at 40 DAS), weed free check and weedy check. The results revealed that weed free check and weedy check was recorded significantly highest and lowest nutrient uptake over rest of the treatments. However, tank mix of atrazine + pendimethalin as PRE was recorded higher NPK uptake followed by hand handing twice at 20 and 40 DAS farmer’s practice of IC at 20 DAS + HW at 40 DAS and pendimethalin fb one HW at 30 DAS. However, highest grain yield was recorded in weed free check (5733 kg/ha) followed by tank mix of atrazine + pendimethalin as pre application (5642 kg/ha), atrazine fb 2, 4-D sodium salt (5600 kg/ha) and atrazine fb one hand weeding at 30 DAS (5563 kg/ha) which were on par with each other and stover yield was followed same trend as in grain yield.

Hand weeding thrice, weed free check and unweeded check were maintained for comparison. sequential application butachlor fb bispyribac sodium, 2,4-D sodium salt and hand weeding at 25 DAS recorded higher grain yield and net returns which were on par with weed free check/hand weeding check. Despite of its effectiveness against weeds and scoring higher rice yields, manual weeding was uneconomical primarily due to higher costs involved. Sequential application of butachlor fb bispyribac sodium or 2, 4-D sodium salt or hand weeding at 25 DAS appeared to be a viable strategy for weed control in direct seeded rice with higher grain yield and economic returns.

Abstract
Indigenous knowledge is the knowledge of the indigenous people inhabiting different geographical regions of the world with their own language, culture, tradition, belief, folklore, rites and rituals. It is part of the lives of the rural poor; their livelihood depends almost entirely on specific skills and knowledge essential for their survival. By the interaction with nature and natural resources for food, fodder and fiber for generation after generation, the ancient farmers developed their age-old, ecologically based farming system (Traditional farming system). The present investigation was undertaken with the aim to document some of the indigenous practices followed by traditional farmers to protect their crops and seeds from various pests and diseases before those are lost under the onslaught of development.

Abstract
The bell pepper (Capsicum annum L. Var. Grossum Sendt.) is one of the important vegetable grown in India. An experiment was conducted to find the effect of spacing’s and different levels of fertilizers on growth and yield of bell pepper under shade net condition. The experiment was conducted at Horticulture Garden, Regional Agriculture Research Station, Raichur analyzed by split plot design. There was increase in leaf area index with advancing age of crop and reached the highest value at 90 day after transplanting. Higher chlorophyll content of leaves was noticed in medium spacing S2. Lower chlorophyll content of leaves was recorded in the treatment F1. Higher fruit weight was recorded in wider spacing (45 × 45 cm) because of translocation of available photosynthates to the sink which has increased the weight of individual fruit. Average weight of fruit was maximum in wider spacing S1 at all the stages. Among levels of fertilizer least average weight of fruit was noticed in F1 treatment. Average weight of fruits was maximum at initial stage. Maximum weight of fruit was in F6 treatment. Among interactions, S1 at F6 recorded higher average weight of fruits.

Abstract
The genetic diversity study in sweet potato (Ipomoea batatas) was undertaken during the year 2012-13 at the Regional Horticultural Research and Extension Centre, Dharwad (Karnataka). Sweet potato genotypes were analyzed for the genetic diversity using the Mahalanobis D2 statistics. Ninety three different sweet potato genotypes were evaluated for five different characters viz yield per plot, yield ha-1, shoot weight, harvest index and weevil infestation. After analysis, genotypes were grouped into 11 distinct clusters. The cluster II constituted maximum number of (42) genotypes followed by cluster VI with 26 genotypes, cluster V (14 genotypes) and clusters IV, VII, IX, X and XI with single genotype each, respectively. Out of the five characters studied, yield per plot (51.89%) contributed maximum to the diversity followed by shoot weight (31.74%), harvest index (6.71%), weevil infestation (5.42%) and yield ha-1 (4.11%). From the cluster mean analysis, means were scored across the 11 clusters for five characters. The lowest cluster mean was given the 1st rank and the cluster possessing the next best mean was given subsequently, next rank. The cluster IX with an overall score of 19 for the selected characters was given first rank, followed by clusters VII and VIII (2nd rank), cluster XI with 3rd rank, cluster III with 4th rank, cluster IV and V with 5th rank, cluster II with 6th rank, cluster VI with 7th rank followed by cluster X with 8th rank. As cluster IX scored highest for the genotypes with desirable traits, it can be used further in the crop improvement of sweet potato crop.

Abstract
A field experiment was conducted during the 2011 and 2012 cropping season, to test the effect of different phosphorus sources (single super phosphate, rock phosphate and combination of single super phosphate and rock phosphate) with or without farm yard manure (FYM) @ 5 ton ha-1, phosphate solubilizing bacteria (PSB) @ 10 kg ha-1 and lime @ 1000 kg ha-1, on yield, nutrients uptake, residual nutrients status and economic returns from upland rice (var. local) under sub tropical hill zone in Nagaland (26°01'562 N latitude, 094°15'860 E longitude and 1209 m elevation). Nutrients (NPK) uptake by rice was increased significantly with the application of phosphatic fertilizers, FYM, PSB and lime. A significant positive relationship was observed with residual soil available phosphorus and availability also increased from 9.23 to 25.97 kg ha-1. Application of lime increased soil pH from 4.58 to 5.26, however, with the application of PSB without lime decreased soil pH from 4.58 to 3.98. The combined application of phosphatic fertilizers, FYM, PSB and lime had significant positive influence on yield and yield components of upland rice. The highest rice yield was obtained with the application of recommended NPK, P as SSP with FYM, PSB and lime. Economic analysis of the upland rice reflected higher gross and net returns when phosphorus was applied in combination with FYM, PSB and lime. Therefore, phosphorus P as single super phosphate (50 to 100%) in combination with P as rock phosphate (50 to 0%) in conjunction, FYM, PSB and lime application may be recommended for increasing soil plant available phosphorus and higher upland rice yield under sub tropical hill zone in Nagaland.

Abstract
In the present study 80 percent rooting was obtained by favourable growth regulator treatment when raised in an ideal rooting medium under greenhouse conditions. The study pointed out that, among the different growth regulator formulations tried, IBA 1000 ppm formulation helped in better induction of rooting by over 70 percent as against 43.33 percent in the control. The next promotive effect in this regard was by treatment of IBA 500 ppm and NAA 250 ppm which recorded 66.67 and 63.33 percent, respectively. However, use of higher concentration of growth regulators, especially IBA at 1500 ppm and NAA at 1000 ppm and their combination at 1000 ppm adversely affected the rooting of cuttings indicating higher concentrations of growth regulators may become toxic to black pepper cuttings.

Abstract
An investigation was undertaken on permanent plot after fourteen years of rice cropping on vertisol resulted that the continuous use of farm yard manure, blue green algae and green manure in conjunction with fertilizers increases the physical properties of soil like infiltration rate, hydraulic conductivity, mean weight diameter and percent water stable aggregates as well as rice yield, and decreased soil bulk density and crack volume. The 100% NPK + FYM resulted highest infiltration rate (8 mm/hr), hydraulic conductivity (1.11 cm/hr) and percent water stable aggregates (48.56). Mean weight diameter highest in 50% NPK + GM (2.093 mm) followed by 100% NPK + FYM (2.051 mm) and lowest in control (1.302 mm). 100% NPK + FYM treatment resulted in lowest bulk density (1.29 Mg/m3) and crack volume (625.73 cm3/m2) as compared to other treatments. The grain and straw yield of rice were higher in where 150% RDF (5065 and 7075 kg/ha) followed by 100% NPK + FYM (4855 and 6565 kg/ha). The results suggest that integrated use of inorganic in combination with organic facilitates optimum soil physical environment for higher crop productivity.

Abstract
Maize is one of the most important cereal crops in the world grown over an area of 132 million hectare with a production of 570 metric tonnes. It is the crop with the highest per day productivity. In India, maize is next in important only to rice and has an acreage around 6m.ha with a production of 10.5 metric tonnes. For Indian maize Taiwan and Bangladesh are depended which have retained major share of its imports from India. The growth of the maize in area, production and productivity has been in a positive rate with an increasing rate. Indian government should necessarily act upon the good rapport and strengthen the relationship in trade. The water in which the maize grains are soaked for the manufacture of glucose is used for growing penicillin moulds. Maize which is being imported from India is used for food, feed as well as industrial purpose too.

Abstract
A farmers’ participatory field trial was conducted to evaluate the growth and yield parameters of rice hybrids at Karnapal village of Chhendipada block in Angul district of Odisha with the financial support from ATMA during rabi season of 2011-12 and 2012-13. The treatments were consisted of six different hybrids and high yielding rice varieties viz Arize 6129 (hybrid), Suruchi 5629 (hybrid), Sahyadri 4 (hybrid), KRH 2 (Hybrid), DRRH 2 (hybrid) and MTU 1001 (HYV). Among different varieties of hybrid rice, Arize 6129 was with maximum grain yield (60.25 q ha-1), harvest index (47.71%), effective tillers per plant (13.5), grains per panicle (165.5), leaf area index (6.75), crop growth rate (6.42 to 33.0 g m-2day-1), relative growth rate (0.0344 to 0.0832 g g-1 day-1) and net return (` 37550 ha-1) was found to be most suitable. Hence the existing high yielding rice variety MTU 1001 can be replaced by hybrid rice Arize 6129 since it fits to the existing farming situation for higher productivity and income.

Abstract
An experiment was conducted at the experimental field of Crop Research Farm, Department of Agronomy, Allahabad School of Agriculture, India, during the rabi season 2011-12. The chickpea variety ‘Pragathi’ was tested against application of zinc (10 kg ha-1, 20 kg ha-1 and 30 kg ha-1), Rhizobium and Phosphate Solubilizing Bacteria in 12 different combinations to study the response of chickpea. Crop characters like number of branches plant-1, number of pods plant-1, number of seeds per pod, dry weight per plant and biological yield were positively and significantly correlated with grain yield. Number of pods per plant alone could be able to influence the grain yield of chickpea to the extent of 92 percent followed by dry weight at harvest (91%) and biological yield per ha (85%) as reflected from their respective R2 values. The maximum gross realization (` 1, 28,203) was observed with the treatment T10 (Application of zinc at 20 kg ha-1 along with Rhizobium inoculation of seed) maximum net return (` 94,538) was also recorded with the same treatment.

Abstract
Field experiment was conducted during winter (rabi) season of 2013-2014 to investigate the effect of different integrated nutrient management practices on soil properties and yield of cauliflower. The 50% recommended dose of nutrient (RDN) + vermicompost-A 5 t ha-1 had recorded highest available N (259 kg/ha), K (400 kg/ha), organic carbon (0.63%) and lowest in control plots. Available P was observed highest (35.35 kg/ha) in 100% RDN followed by 50% RDN + vermicompost-A 5 t ha-1 (34.44 kg/ha) and lowest in control (13.60 kg/ha) plots. The yield of cauliflower was maximum in 50% RDN + vermicompost-A 5 t ha-1 (5817 kg/ha) followed by 100% RDN (5716 kg/ha) and minimum in omission of inorganic and organics i e absolute control (1667 kg/ha). The results suggest that integrated use of inorganic combination with vermicompost facilitates optimum soil chemical environment which reflects on yield of cauliflower.

Abstract
An investigation was carried out to estimate the combining ability and heterosis for yield and yield related traits in maize hybrids synthesized by adapting line × tester design with twenty four lines and three testers. The variance due to SCA was higher than GCA indicating the predominance of non-additive type of gene action in the governance of studied traits. The lines viz UMI 1093, UMI 1044-7, UMI 1029-5 and UMI 2244-1 and the testers viz UMI 61 and UMI 1119 was found as the best general combiners with better performance for most of the yield contributing traits. Among the hybrids, UMI 1044-7 × UMI 61 and UMI1093 × UMI61 was identified as superior as it recorded high magnitude of per se performance, significant positive SCA effects and standard heterosis for grain yield, while UMI 2128-1 × UMI1119 was identified as best hybrid for earliness. The crosses, UMI 1044-7 × UMI 61, UMI 1093 × UMI 61 and UMI 2128-1 × UMI 1119 involving parents of positive and significant gca effects and high heterosis for grain yield can be exploited further after testing across locations and environments to ascertain their yield stability. From the study it was evident that the single cross hybrids synthesised by using exotic (CIMMYT) lines as females will improve cob and grain traits in domestic maize hybrids.

Abstract
Studies on population dynamics of tea mosquito bug (Helopeltis theivora) Waterhouse (Hemiptera: Miridae) were carried that the highest tea mosquito bug population (39.60/3 shoot) in PIM was recorded in July, 2011 and lowest (6.25/3 shoot) was during March, 2012. Population build up of H. theivora showed significant positive correlation with the maximum (r = 0.824) and minimum (r = 0.753) temperature, evening relative humidity (r = 0.677) and number of rainy days (r = 0.656). Multiple regression analysis of tea mosquito bug with different weather parameters showed 95.50 (100R2 = 95.50) variation in population in PIM. A natural enemy of tea mosquito bug is Oxypus sp. also showed significant positive correlation with tea mosquito bug population. The correlation of Oxyopes sp. with those of weather parameters showed that temperature (maximum and minimum), relative humidity (evening), total rainfall (mm) and number of rainy days had significant positive relation with the population of lynx spider (Oxyopes sp.). Whereas, relative humidity (morning) and BSSH showed non-significant relation with Oxyopes sp.

Anthracnose caused by Colletotrichum truncatum (Schw.) Andrus and Moore is one of the major diseases of mungbean (Vigna radiata L. Wilczek). The disease has become one of the major constraints for mungbean cultivation. The effect of temperature and pH on the mycelia growth, sporulation and spore germination of Colletotrichum truncatum were studied in laboratory condition. C. truncatum isolated from infected mungbean leaves was grown in Petri plates maintained at various temperature (10, 15, 20, 25, 30, 35 and 40°C) and in flask maintained at various pH (4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5 and 8.0) levels. Physiological studies revealed that the optimum range of temperature and pH for the growth and sporulation of fungus were 25°C to 30°C and 5.5 to 7.0, respectively. Maximum fungal growth and sporulation of C. truncatum were recorded at 30°C (80.41 mm) followed by 25°C (79.49 mm) while it was minimum at 40°C (19.49 mm). Maximum dry weight of mycelium and sporulation was recorded at 6.5 pH (104.27 mg) followed by 6.0 (94.53 mg) while it was least at 8.0 pH (48.45 mg). However, optimum growth of fungus was also observed at pH of 5.5 to 7.0.

Abstract
Heterosis in rice was studied for yield and quality traits in 24 hybrids generated by crossing of six lines and four testers. Relative heterosis, heterobeltiosis and standard heterosis were estimated for yield and quality characters. The high manifestation of heterosis was observed in seven crosses Samba Mahsuri × Jagtial Samba, Akshayadhan × JGL-11727, Surekha × Ramappa, Samba Mahsuri × Ramappa, Warangal Samba × Jagtial Samba, Warangal Samba × Ramappa and Akshayadhan × Early Samba for grain yield. The maximum expression of heterosis (79.21%), heterobeltiosis (70.59%) and standard heterosis (88.76%) for grain yield per plant were observed in cross Samba Mahsuri × Jagtial Samba. The hybrids Samba Mahsuri × Jagtial Samba and Warangal Samba × Ramappa performed well for grain yield combined with several grain quality traits viz milling percentage, kernel length, L/B ratio, kernel length after cooking and kernel elongation ratio, so these promising cross combinations can be further used.

Abstract
A comparative study was made for the storage of tomato fruits inside the zero energy cool chamber (ZECC) and in ambient condition for their weight loss, changes pH levels, TSS and firmness. The ZECC does not require mechanical or electrical energy input and can be constructed with locally available material by unskilled labour. Hourly temperature and relative humidity were recorded inside and outside the chamber for a particular day. The results revealed that inside temperature was about 1.57 - 11.68°C (ΔT = 4.29°C) lower than outside temperature and inside humidity was about 24.08 - 68.73% higher than outside. Physiological loss in weight (PLW) was faster for fruits stored at ambient temperature. Weight loss during the storage at ambient temperature was 6.41% as compared to 4.9% in ZECC. The TSS of tomatoes increased from 4.20 to 5.20% at ambient temperature after 5 days of storage and from 4.10 to 4.90% at ZECC after 9 days of storage inside the ZECC. pH value during 9 days of storage at ZECC slowly increased, ranging from 4.15 to 4.41, butin case of outside the same was 4.19 to 4.34 after 5 days. The ZECC stored tomatoes maintain more uniform colour and firmness than outside stored one. The higher firmness of fruits inside the ZECC was likely due to lower temperature and higher humidity maintained inside the environment.

Abstract
Five male sterile lines were crossed with eleven testers and the resultant fifty five hybrids were utilized for correlation and path analysis studies. Grain yield per plant was found to be positively and significantly correlated with plant height, number of leaves per plant, number of productive tillers per plant, earhead length, earhead girth, earhead weight, grain yield per earhead, stover yield per plant at genotypic level. This indicated the importance of plant height, number of leaves per plant, number of productive tillers per plant, earhead length, earhead girth, earhead weight, grain yield per earhead, stover yield per plant in influencing the grain yield in pearl millet. The characters, grain yield per earhead and number of productive tillers per plant exerted maximum direct effect on grain yield per plant indicating its importance in determining grain yield per plant, and also stover yield per plant. Earhead girth and number of leaves per plant exerted direct effect on grain yield per plant. Selection based on these characters may be helpful in planning efficient breeding programme.

Abstract
Present study was done for the influence on nitrogen on resistance genes and bacterial blight development of rice under Chhattisgarh condition during kharif and rabi season in two years. Three rice genotypes- IRBB-4 (Xa 4), IRBB-5 (Xa 5) and IRBB-21 (Xa 12) with four levels of nitrogen (N0, N40, N80 and N120) were taken as treatments. Nitrogen levels were applied thirty five days after planting. When the plants were at maximum tillering stage, they were clip inoculated with bacterial inoculum. Observations were recorded from 7th day onwards at an interval of 7 days for a period of 21 days i e three observations. Yield (kg plot-1) was estimated (bundle weight and grain weight) after harvesting. All the three genotypes differed significantly and the interaction between genotypes and nitrogen levels were also significant. IRBB-21 (Xa 21) showed significantly superior or resistant as compare to the other genotypes IRBB-4 (Xa 4) and IRBB-5 (Xa 5). There was a progressive increasing trend as the days after inoculation increases in all the three genotypes. Minimum percent disease development was recorded in V1N1 (1.13%) and maximum percent disease severity was recorded in V2N4 (37.03%).

Abstract
Arecanut being the pivotal component of Integrated farming systems in Southern Karnataka determines the fate and fortunes of farmers. It is imperative to assess the magnitude and stability of farm income which has profound influence on livelihood and economic security of farmers. Hazel’s decomposition analysis has been employed for cross section data on arecanut production and prices at meso level to assess the stability in farm income. The outcome of the study indicated that magnitude of farm income from arecanut was on lower side due to high cost of cultivation. The net returns from arecanut was small as price did not increased proportionately enough to cover the high cost on account of inflationary tendency of all cost items. Considering the small size holdings and perennial nature of arecanut, the income accruing is no way sufficient. Further returns were found to be unstable too. The outcome of Hazell decomposition indicated the decline in gross returns in all of the study area except Tumkur, despite increase in the production of arecanut over time but due to fall in its real prices. Further change in average production was identified as the major source of instability of gross returns from arecanut in the case of Shimoga and Tumkur.

Abstract
The study revealed that in the month of April 2002 the transportation cost for a liter was 0.72 paisa and at the end of the year it found 0.75 paisa, increase of 0.03 paisa with a growth rate of 0.79 percent per annum. The highest seasonal indices were observed during the month of November (115.47) and the lowest seasonal indices for the procurement of milk was observed during the month of May (86.95). In 2002 the DCSs price was ` 13.65 per liter and it was ` 23.85 in 2011. It has increased over the study period at the rate of 6.41 percent per annum. The market price of BEMUL milk products in Goa were more compared to Belgaum. The major market for Nandini milk and its products was in Belgaum and Goa. The revenue from liquid milk sale and its products varied between the years 2002-2011. This is mainly because people in Belgaum depending on agriculture are more and also irrigated cultivable land is more, this accounts for more production of milk. The revenue from milk derived products has followed an increasing trend from 2002 to 2011.

Abstract
The associations among seed and seedling components, and their direct and indirect influence on the grain yield of rice were investigated. For this purpose, 60 rice genotypes were studied in a randomized complete block experiment design with three replications at the ARS, Siruguppa in kharif 2011-2012. The phenotypic correlations among the traits and their path coefficient were estimated. Grain yield was significantly positively correlated phenotypically with its component of seed and seedling characters like the grain length and L/B ratio and negatively correlated with shoot length at 14th DAS and vigor index. In case of path analysis root length at 10th DAS has maximum direct positive effect on grain yield fallows vigor index, where as shoot length at 14th DAS has maximum direct negative effect on grain yield fallows seedling dry weight. The improvement in grain yield will be efficient, if the selection is based on the grain length, L/B ratio, grain length, grain width and vigor index. These traits may also be utilized for pure line selection in later generations.

Abstract
The pot culture experiment was done during the period of 2010-11 in TNAU, Coimbatore. Results revealed that, the plant receiving NPK, FYM, neem cake, biofertilizers, vermicompost and SSB were less preferred by the BPH for feeding. The application of organic nutrition resulted in the reduced percent of nymphal survivility, reduced fecundity, reduced population build-up and reduced adult longevity. This has confirmed the mechanisms of induced resistance in terms of antibiosis.
