The research work was carried out to analyse the variability parameters, correlation and path coefficient for morphological characters and quantitative traits in twenty five tomato genotypes. Analysis of variation revealed significant differences between the genotypes for all the traits. High genotypic and phenotypic coefficient variation were observed for average fruit weight followed by number of fruit/plant and number of fruit cluster/plant and lowest for days taken to first fruit harvest. High genetic advance was obtained for fruit yield/ plant, yield/ hectare and plant height. fruit yield quintal / hectare was positively and significantly correlated with average fruit weight and fruit yield/plant. Maximum positive direct effect on fruit yield / hectare was imposed by number of primary branches / plant followed by days taken to 50% flowering and number of fruit cluster/plant. Whereas, at genotypic level, maximum positive direct effect on fruit yield/hectare was imposed by plant height followed by days to flower initiation and days taken to first fruit set. The genotypes viz., CLN-2123E (364.03 q/ha), EC-519800 (355.15 q/ha) and CLN-2870A (351.74 q/ha) were found better than to check PT-3 and superior for yield quintal / hectare.

Jhalawar is one high rainfall district falls under agro-climatic zone – V (South eastern Humid Plain zone) of Rajasthan. The average rainfall of the district is around about 950 to 1000 mm per year. Most of the area is irrigated. There are the two major cereal crops grown in the district i.e. Maize (Zea mays) during kharif and Wheat (Triticum aestivum L.) during rabi season. The Krishi Vigyan Kendra also known as Farm Science Centre of the district laid down Front Line Demonstrations on these cereal crops under Integrated Village Livelihood Development Project (IVLDP) and ICAR for introducing new varieties along with scientific practices in their cultivation. The productivity as well as the economic returns of cereals in improved technologies (FLDs) were calculated and compared with the corresponding farmer's practices (local checks). Both the cereal crops maize and wheat recorded average higher gross returns Rsha-1 22833 and 41250, net return Rsha-1 11400 and 9000 and benefit cost ratio 2.16 and 1.28, respectively in improved technologies (FLDs) as compared to the plots where farmers were using traditional practices in their cultivation.

Groundnut (Arachis hypogea L.) is the fifth largest oilseed crop after soybean, rapeseed, cotton and sunflower in the world, which account for 7.3 per cent of the total world oilseed production (www.soystats.com). Augmented Dickey Fuller test, Johansen’s Multiple Co-integration analysis, Vector Error Correction Model and Granger causality tests were employed in this study. The results indicated that the selected groundnut markets were integrated and prices in Kurnool market and Yemmiganur market exhibited a bidirectional influence at five per cent level of significance, whereas unidirectional influence was exhibited by Gondal market on Kurnool and Yemmiganur markets. The results of the test pointed out that Gondal market was the lead market.

Coarse textured soils of arid and semi arid regions are highly permeable and loss of water as well as soluble nutrients especially sulphur is quite high from these soil. With this view, a field experiment was conducted on loamy sand soils to study the response of compaction (0, 2, 4 and 8 passes of 500 kg manually driven iron roller) and sulphur (0, 15, 30 and 45 kg S ha-1) fertilization through gypsum on nutrient content, uptake, protein and economics of barley crop. Significant improvement in content and uptake of nitrogen, phosphorus, potassium, and sulphur were observed up to 4 passes of 500 kg iron roller and 30 kg S ha-1. A significant increase in protein content in grain of barley was also observed under 4 passes of iron roller with 30 kg S ha-1. Increased levels of compaction retained more amount of sulphate in 15-30 cm soil layers. Significantly higher net return (Rs. ha-1) was fetched with the combined use of compaction by 4 passes of 500 kg iron roller and 30 kg S ha-1. However, optimum level of S (49.96 kg ha-1) was worked out higher in response study but a more realistic level of 30 kg S ha-1 could be safely recommended with compaction for barley crop.

Wheat, which has been considered as the “multipurpose cereal food” for different centuries continues to hold on this honour with its lineage penetrating deep into the depths of human culture. Wheat competes good enough with other cereals in it’s nutritive parameters. The nutrition summary of wheat is 12.1 percent protein, 1.8 percent lipids, 1.8 percent ash, 2.0 percent reducing sugars, 6.7 percent pentosans, 59.2 percent starch, 70 percent total carbohydrates. It also imparts energy of 314K cal/100g of food (1). Genetic variability, heritability, genetic advance was evaluated for Ninety Six wheat accessions collected from different parts of MP for yield and its attributing characters. Analysis of variance discovered highly significant differences among genotypes with regard to all the quantitative characters studied, thus illustrating presence of ample genetic variability among genotypes. The phenotypic and genotypic coefficient of variation was identified to be high for biological yield/ plant, grain yield/plant and harvest index, moderate for tillers/plant, days to 50% heading and 1000- grain weight and low for ear length and days to maturity. This signified prevalence of enough genetic variability for the characters studied other than ear length and days to maturity. Heritability estimates was found to be high for all the characters studied. The characters viz., tillers/plant, days to 50% heading, 1000- grain weight, biological yield/ plant, grain yield/plant and harvest index showed high heritability coupled with a high genetic advance representing that simple selection scheme would be good enough for these traits to carry out genetic improvement in preferred direction.
