| Abstract: | The optimum rate of NPK fertilizer application for soybean was studied at central area of Jilin Province, in order to provide the basis for high yield and high efficient of soybean production. By making Jiyu 88 as experimental cultivar, designed the different fertilizer level on NPK in field during 2006-2007. The results showed the optimum rates of N,P,K application were 45-67.5 kg·ha~(-1) ,60-90 kg·ha~(-1),45-80 kg·ha~(-1) respectively. The effect order of NPK fertilizer on soybean yield was N > P > K. |
