| Abstract: | A fertilizer experiment of N,P,K was conducted by using the superior design method.We have get a function model of corrslation between three factors and yield.This paper describes the yield effects and interaction of the three factors.Applied rates of the highest yield.The best beneficial returns at different yield levels and combining proportion of N,P,K were caculated respectively.This conclusion can be used as a base of peanut fertilization. |
