Yield of soybean influenced by varying depth of vertisolp and dates of planting

Response of soybean (Glycine max L. Merr.) to varying depths (shallow, medium deep, deep) of vertisols and three sowing windows (9^th, 19^th and 29^th May) was studied during Kharif season of 2003 and 2004 at Shirol in Kolhapur District, Maharashtra. Medium deep soils produced significantly higher yields than deep and shallow soils by producing more number of pod and seeds m”² while delayed sowing reduced the number of seeds m², biomass and yield ha ‘. Sowing in medium deep soils at 9^th May gave higher yields.
