Abstract: In order to manifest the effect of application of NPK of sunflower field in Hetao irrigated area of Inner Mongolia. A 3-factor and 2-degree common rotary design was used to analyse and simulate the effect of application of NPK in Hetao irrigated area of Inner Mongolia. The result of study show that application of NPK can increase yield of oil sunflower in Hetao irrigated area, and it can be expressed by a 3-factor and 2-degree mathematical modal. Highest yield was 307.2 kg/667m2, optimum proportion of NPK was 1.38:1.37:1.

Key words: Oil sunflower, The effect of application of NPK, Optimum proportion line
