| Abstract: | Mathematical models between the nitrogen fertilizer amount applied, distribution ratio and yields and benefits were established by the adoption of Square Saturation D optimized Design in wheat and peanut cropping system. The effects of nitrogen amount applied and distribution ratio in wheat and peanut on yield and benefit were discussed. Approaches of applying nitrogen were recommended for obtaining a total yield of wheat and peanut>12 000kg/hm 2 and benefit>23 000yuan/hm 2. |
