ThesisItem Open Access Effect of herbicides on physiological parameters, growth, yield and quality of soybean (Glycine max L.)(JNKVV, 2015) Singh, Neelu; Dwivedi, S.K.ThesisItem Open Access Pattern of biomass partitioning, growth, productivity and quality of soybean (Glycine max (L.) merrill) genotypes under high plant population(JNKVV, 2015) Dewangan, Yogeshwar Kumar; Dwivedi, S.K.The present investigation entitled “Pattern of biomass partitioning, growth, productivity and quality of Soybean (Glycine max [L.] Merrill) was conducted at the Research Farm of the Department of Plant Breeding & Genetics, JNKVV, Jabalpur during Kharif season 2014. The treatment combination compared of two plant population density and five soybean genotypes, alone as well as, in combination in factorial RBD replicated there. The various treatments of plant population and genotypes and their interaction showed a wide variability among themselves in relation to phenophasic development, physiological, biochemical and yield attributes as well as seed yield of soybean. Increase in optimum plant population to higher plant density caused a significant delay in shifting of various phenophases viz. Flower initiation, general flowering, pod formation and maturity. A pattern of increase in LAI was obtained with an increase in plant population density from early vegetative stage to crop maturity with a reduction in LAI after 75 DAS. Maximum LAI was noted with P2 and V2 during pre flowering and P 2 and V5 during pod development period .The LAD increase up to 60 -75 DAS and beyond that a sharp reduction was observed maximum LAD was recorded in P 2 and V2 similarly CGR ,RGR and SLW was also noted up to 60 DAS in P 2 .V2 attained higher CGR, V5 RGR and SLW up to 60 DAS their a diminution trend was exhibited Net photosynthesis rate, stomatal conductance ,transpiration rate, chlorophyll content index and RW C were significantly influenced by crop density and genotypes. Enhancement of plant population caused a significant reduction these traits. V2, V3 and V5 were superior among various genotypes with regards to their physiological traits. Similarly increas e plant population of soybean significantly reduced seed quality of soybean .Maximum seed protein (%) seed oil (%), fibre, carbohydrate and ash were estimated under optimum plant population (P 1) while seed protein yield and seed oil yield was maximum in higher plant population (P 2) density due to high seed yield .V 5 and V2 were superior among genotypes in relation to seed quality parameter. The improvement in yield attributing parameters due to crop density and genotypes finally resulted in maximum realiza tion of productivity potential of soybean .plant height was maximum in optimum plant population density and V4. No of branches, nodes, pods, pod weight, seed index and total dry matter production and seed yield per plant were maximum in P 1 on the other head biological yield, harvest index were maximum in high crop density. Among genotypes V 3 maintained in superiority in improved morphological, structural component of productivity and registered maximum seed yield (Q/ha).ThesisItem Open Access Physiological evaluation of growth, dry matter partitioning, seed yield and quality of soybean [glycine max (L.) merrill] as influenced by excess moisture stress condition(JNKVV, 2015) Soni, Bhaskar; Dwivedi, S.K.ThesisItem Open Access tudy of morpho-physiological traits and productivity in soybean (Glycine max (L.) merrill.) under varying sowing systems(JNKVV, 2015) Kushwaha, Raghuveer Singh; Gontia, A.S.ThesisItem Open Access Investigations on physiological efficiency and productivity in soybean (Glycine max (L.) merrill), under different sowing dates, tillage and drainage methods(JNKVV, 2015) Balasaheb, Kanase Tejas; Gontia, A.S.ThesisItem Open Access Mitigation of drought for improving productivity by foliar application of urea and salicylic acid in chickpea (Cicer arietinum L.) genotypes(JNKVV, 2015) BIsne, Pravin Suklal; Pandey, S.K.ThesisItem Open Access Morpho-physiological traits and productivity in garden pea (Pisum sativum L.) as influenced by various methods of potassium humate - 4.5 application(JNKVV, 2015) Patel, Dhanraj; Gontia, A.S.ThesisItem Open Access Differential responses of sesame (Sesamum indicum L.) genotypes to staggered date of sowing(JNKVV, 2015) Upadhyaya, S.D.
