| Abstract: | The objectives of this study the relationship of the wheat production and nitrogen,phosphorus and potassium best fertilizer content. To establish the regression equation of a nitrogen（N）, phosphorus（P）, potassium（K）fertilizer and the wheat output （Y）. The result showed that the best fertilizer content in the wheat for N 213.91 kg/hm2, P2O5 726.25 kg/hm2, K2O 62.27 kg/hm2, and prediction value of production is 2 585.10 kg/hm2. |
