Abstract

                                A field experiment was conducted with four levels of N and three levels of P, Os and K.O alone and in combination to study their effect on the yield and quality of IR 8 rice. The results revealed that the maximum yield of grain was obtained at the level of 180 kg N/ha and beyond this level there was no response for nitrogen. Increased appli- cation of N increased the crude protein and true protein content of, the rice grain. Phos phorus, potassium and magnesium content of the grain were increased by the application of phosphorus. Carbohydrate content of the grain was not influenced by the application of fertilizers.
