| Abstract: | This paper described the effects of nitrogen, phosphorus and potassium on soybean yield through using best-regression design. A mathematical model was established for a yield of 230 kg/mu and an output of 380 yuan/mu, in which the application amounts of pure nitrogen, phosphorus and potassium were 3.4-4.2 kg, 3.6-5.2kg and 2.7-3.6kg per mu respectively. The sequence of role of the three nutrient factors on soybean yield was as P>N>K |
