A field experiment was conducted to evaluate the effect of water table management on dynamics of soil water, crop yield and WUE of spring maize. The water table management consisted of six water table control set at 0.5 m, 1.0 m, 1.5 m, 2.0 m, 2.5 m, 3.0 m from soil surface and one free water table. The results showed: different water table has most influence on 0~100 cm soil layer water content of spring maize field. Soil water content varies more seriously under shallower water table, and it lead to more ground water uptake and more water use. The start day of percolation after irrigation or rainfall lagged under deeper water table. The higher crop yield and WUE occurs when water table set at 1.0 m during whole growing season. WUE decrease when water table increase from 1.0 m.
