Study of quantitative and quality characteristics of soybean genotypes in deficit irrigation conditions
Abstract:   (3689 Views)
To study growth and yield in 19 genotypes of soybean under deficit irrigation conditions, three separate experiments were carried out-using randomized complete block design with three replications. Three irrigation regimes were applied in three experiments: Experiment 1: after 50 (optimum irrigation), Experiment 2: after 100 (moderate stress) and Experiment 3: after 150 millimeters (severe stress) evaporation from evaporation pan class A. Results showed that the Irrigation regimesgenotype interaction had significant effect on the number of seeds per unit area, oil and protein contents. Deficit irrigation had significant effect on the number of nodes, plant height, number of branches, number of pod.m-2, number of seed.m-2, grain yield, productivity index (pod weight/total dry weight), proteins and oil contents. Severe stress conditions had maximum effect on reduction in branch number, number of pods.m-2, grain yield, productivity index, oil and protein contents. Grain yield in moderate and severe stress conditions had positive and significant correlation with STI, MP, GMP indices. The highest grain yield was obtained from genotypes L11 and Clean in moderate and severe stresses conditions, respectively.
Keywords: Deficit irrigation, Productivity index, Soybean and Stress tolerance index
