ABSTRACT

A field experiment was conducted during early rabi season of 2014-15 on clay loam soil at Agricultural College Farm, Bapatla, Andhra Pradesh, to study the influence of sowing dates and varieties on seed quality of soybean in Coastal AP’ Early sowing of soybean on 15th September recorded the highest protein content of 34.9 per cent which was on a par with 15th October sowing of soybean and it was significantly superior over 15th November and 15th December sowing. Among the varieties, highest protein content of soybean was recorded with the variety JS-93-05 (35.2 %) which was significantly superior over the other two varieties JS-335 (32.5%) and Local (44.1%). The highest seed quality (Germination %, Seed viability, and seed vigour) of soybean was recorded with soybean sown on 15th September with variety JS-93-05 both at harvest and 30 days after harvest.
