Effect of seed dressing on germination and root rot of soybean

Abstract

Field trial were conducted at three locations to find out the effect of different chemical seed dresser and bio-agent on seed germination, root rot incidence and yield of soybean and results revealed that in comparison with bio-agent (Pseudomonas fluorescens and Trichoderma viride) seed dressing with Carboxin 37.5% + Thiram 37.5% (combi product) @ 2g/kg seed recorded maximum seed germination (92.96%), least per cent incidence of root rot (1.01, 2.79 and 6.22%) at 15, 30 and 45 days after germination respectively. Significantly superior yield (1224 kg/ha) recorded in seed dressing with Carboxin 37.5% + Thiram 37.5% (combi product) which is at par with seed dressing with Carbendazim 25% + mancozeb 50% WS (combi product) @ 2g/kg seed. Higher yield ascribed due to increased seed germination, minimum root rot incidence.
