Effect of Varieties and Plant-densities to Yield and WUE in Dryland Maize

With Nongda 108 and Zhendan 958 as maize varieties,it studied the effect of two varieties and plant-densities to yield and WUE of maize in dryland;the results showed that under the same density,Zhendan 958s’ yield was higher than Nongda 108,and under lowdensity,the grain number per spike of Nongda 108 was bigger than Zhendan 958,and under high density,the grain number per spike and hundred grain weight of Zhendan 958 were better than Nongda 108.
