| Abstract: | The quantitative relationship between the yield of soybean and the amounts of nitrogen,phosphorus and potash fertilizers and the supply potential of soil nutrient in Shangqiu,Henan Province were studied using ＇3414＇ regression design model.The effect equation between the yield and the nitrogen,phosphorus and potash fertilizers was established to calculate the optimum amounts of fertilizers.The optimum economic amount of N,P2O5 and K2O was 46.41 kg/hm^2,58.42 kg/hm^2 and 66.66 kg/hm^2,respectively,and the optimum economic yield was 4 129.45 kg/hm^2. |
