In order to evaluate scientifically the application effect of integrated irrigation and fertilizer management on dryland crops, and explore and master the relevant technique parameters, the field experiment was conducted to study the effect of this technology on growth of potato under different fertilization levels. The results showed that compared with the conventional irrigation （spraying irrigation） and fertilizer treatment,integrated irrigation and fertilizer management could save water 47.2%, yield of potato increased 2.2%-4.4%,income increased 4 071.3 Yuan/hm2-9 923.4 Yuan/hm2 and increasing rate by 10.9%-26.5% ;Therefore,40%-60% of conventional fertilizer applying amount is suitable when applying the new technology on potato.
