Forty five genotypes of Indian mustard [Brassica juncea (L.) Czern and Coss] were evaluated for seed yield and quality traits in Randomized Block Design with four replications during the Rabi, 2019-2020. The analysis of variance revealed that the mean sum of squares due to genotypes was significant for all the eighteen characters studied indicating the presence of variability for all the traits among the genotypes under study. Low difference between genotypic and phenotypic variances revealed that the contribution of genotypic variance to total variance was more for all the traits except days to maturity and plant height. The high values of genotypic and phenotypic coefficient of variation for the number of branches per plant, seed yield per plant , myristic acid, palmitic acid and stearic acid which indicated the potential variability available for these traits. The high heritability estimates obtained in conjunction with high genetic advance were observed for the number of branches per plant, the number of siliquae per plant, seeds per siliqua, length of siliqua , 1000-seed weight , seed yield per plant , myristic acid , palmitic acid, stearic acid , linoleic acid , linolenic acid and glucosinolate suggesting the predominant role of additive gene action for their expression. Association analysis between seed yield per plant and other seventeen characters revealed significantly positive correlation of seed yield per plant with the number of siliquae per plant, seeds per siliqua, length of siliquam, myristic acid and erucic acid. Path analysis revealed positive direct effects of the number of siliquae per plant and seeds per siliqua towards seed yield per plant while myristic acid, the number of branches per plant had a positive indirect effect on seed yield per plant via the number of siliquae per plant suggesting that the selection for such traits would be more effective for improving seed yield in Indian mustard.
Soybean, being an important pulse as well as oil seed needs special mention to overcome crisis in edible oil production in the country. It is also called as “Gold of soil”. An experiment was conducted at College of Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during kharif (Soybean) and rabi (Amaranthus) season of the years 2019-20 and 2020-21. An agronomical investigation entitles effect of integrated nitrogen management in soybean and their residual effect on grain amaranthus under irrigated condition. The experiment soil was medium in organic carbon (0.40%), available phosphorus (36.20 kg/ha) and available potassium (209 kg/ha) with soil pH (8.15). There were ten integrated nutrient management treatments arranged in Randomized block design with four replications. Integrated used of the organic and inorganic sources of plant nutrients on growth and yield attributes is very crucial for the assurance of food securities. Different observation on the crop parameters were carried out during course of investigation. Integrated nitrogen managements did not exert any significant response on plant population recorded at 20 DAS and at harvest and plant height at 30 DAS. All growth and yield parameters viz., plant height at 60 DAS, plant height at harvest, number of branches/plant, root nodules/plant, dry weight of root nodules, seed yield and straw yield were recorded significantly higher with the application of 50% RDN through vermicompost + 50% RDN through inorganic fertilizer (T3) sustainable agricultural productivity might be due to achieved through wise used of integrated nutrient management. At present soybean is one of the most important economical crops and having good nutritional response on healthy diet and information of same cropping sequence was not available for farming community so planned study on the application of organic sources of nutrients viz., vermicompost, FYM, bio-fertilizers (Rhizobium + PSB) under middle Gujarat conditions.
