| Abstract: | The relationship between yield and fertilizer application wasstudied by means of “3414” method under different amounts of N,P and K applied. The best combination of amounts of N,P and K applied was obtained by establishing with a regression equation. The results showed that the best combination is N 119.24 kg, P2O599.88 kg and K2O 128.82 kg/ha, and that the yield would reach to 2 713.23±112.46 kg/ha with 95% confidence. |
