This paper approached the effects of the technique of balanced fertilizer on water application efficiency of dryland corn. In the semihumid and slightly arid areas of Eastern parts of Shanxi and Western parts of Henan Province, the sixyear field experimental results showed that adopting the appropriate variety, amount of fertilizer,stages and method of application is advantageous to raise the water use efficiency of dryland corn. Furthermore, it can improve the soil fertility and further promote the water application of dryland corn.
