Abstract
A field experiment imposing foliar sprays of growth regulators and two fungicides at different crop growth stages in two varieties of soybean was conducted during kharif 2022 to identify appropriate prophylactic measures to combat the seed damages during developmental stages so as to reduce seed deterioration and thereby improve the longevity of seed at College Farm, College of Agriculture, Rajendranagar. Seed quality data was recorded. The laboratory studies under storage were conducted in FCRD with two replications and observations on various seed quality traits viz. germination (%), seedling dry weight (mg) seedling vigour index and field emergence (%) . Among the various treatments T6 viz. Pyraclostrobin + Thiophonate (Xelora) @ 2 ml/l at pod formation, seed development and seed maturity showed superior performance for yield, yield attributes and seed quality.
Keywords: Soybean, foliar sprays, germination, field emergence and seedling vigour index
