The field experiment was carried out to study the effect of foliar spray of micronutrients and growth regulators on seed quality of onion during rabi 2016-17 and 2017-18 at Seed Unit, UAS, Raichur. Foliar spray was given at 45 and 75 days after bulb planting (DAP). The seed quality parameters were recorded at Seed Unit, UAS, Raichur. From the present investigation, a significant increase in seed quality parameters were recorded with foliar spray of ZnSO4 @ per cent viz., root length (, and cm), shoot length (, and cm), seedling vigour index (2026, 2049 and 2037), seedling dry weight (, and mg), dehydrogenase enzyme activity (, and OD value) and α-amylase enzyme activity (, and mm) followed by GA3 @ 100 ppm over control viz., (, and cm, , and cm, 1773, 1823 and 1798, , and mg, , and OD value and , and mm) during 2016-17, 2017-18 and pooled data, respectively. The non significant differences were observed due to influence of foliar spray of micronutrient and growth regulators on seed germination per cent and electrical conductivity. | Effect of foliar spray of micronutrients and growth regulators on seed quality of onion
