Abstract


Field experiment conducted on soybean, greengram, blackgram and cowpea with four levels of sulphur vis; 0,20,40 and 80 kg S/ha in alluvial soils at College of Agriculture Gwalior, indicated a significant increase in the yield. The magnitude of increase in the yield was higher for soybean and cowpea. An increase in the concentration and uptake of N,P,K and S was noticed. A significant negative relationship between N:S ratio and yield suggests that a wider N:S ratio will drastically reduce the crop yield.
