With Deyou 8 as the material, the effects of different fertilizer treatments with N, P, K on yield and economic benefit of rape were studied. The results showed that the effect of N on rape was the best. The highest yield gain of rape in treatments with N, P, K were 1 582, 467 and 133 kg/hm~2 with increasing rates of 105.2%, 19.3%, 4.8% and net income increase of 3 068, 895,-288 yuan/hm~2 resp. According to the fitted fertilizer efficiency model, the application amount of N, P_2O_5, K_2O with the highest yield of rape was 237.45, 106.41 and 152.73 kg/hm~2 resp. and the most economical application amount of them was 201.84, 77.28 and 0 kg/hm~2 resp.
