| Abstract: | The effects of the amount and ration of N, P and K on the yield of high quality late rice were studied by use of 3414 field experiments suggested by FAO, i.e. three factors, four levels and fourteen treatments. Furthermore, the mathematics model was also obtained. The amount of fertilizers used to obtain the optimal production through the optimization and analysis of model was 202.5?kg/hm 2 for N; 0.0?kg/hm 2 for P 2O 5 and 303.0?kg/hm 2 for K 2O,and the yield for late rice with high quality was 5?491.5?kg/hm 2. |
