The results of a pot experiment where 0, 20, 40, and 60 ml/kg soil of both P and S, were applied to paddy grown under low land conditions show that it increased the available P and S content in soil, their uptake and yield of paddy. Available P and S content under in situ condition at flowering and harvesting stages was higher and significantly and positively correlated to grain yield. The grain:straw and P:S uptake ratio increased up to 40 mg level of each P and S but N:S uptake ratio increased only up to 60 and 40 mg level of P and S application respectively. Other effects on uptake of macro and secondary nutrients are also discussed
