Response of soybean (Glycilze max) to phosphorus and sulphur in Acid alfisol of Meghalaya

Abstract

A field experiment was conducted during the rainy (kharif) season of 1998 and 1999 on a phosphorus and sulphur deficient Hapludalf, to evaluate the influence of different levels of phosphorus and sulphur on yield, yield attributes, nutrient uptake and seed quality of soybean [Glycine max (L.) Merr.]. All the P and S levels significantly increased the grain and straw yields, podslplant, 100 seed weight, oil and protein content and their yields and N P and S uptake by soybean. The N : S ratio in the seed reduced significantly by both P and S application. Interaction of P and S was also significant for all the parameters studied. Application of 60 kg P,O, along with 40 kg Slha was the optimum dose of P and S for getting the highest yield.
