The fertilizer requirement for rice for an acre is 50 kg nitrogen, 12 kg phosphorus, and 12. kg potassium. Potassium dose should be applied on a soil test basis. Divide nitrogen dose into three parts. Apply one part of nitrogen and a whole of phosphorus and potassium (if needed) before the last puddling. The remaining two parts of nitrogen are broadcasted in two equal splits at three and six weeks after transplanting. If rice is sown after wheat which had received a recommended supply of phosphorus, then there is no need to apply phosphorus for rice crops.
