Effect of Different Fertilizer Amount and Plant Density on the Yield and Benefit of Summer maize

Gao Feng-ju

Abstract

The present study was carried out to characterize the best plant pattern of summer maize,in Dezhou region.The effects of fertilization and density on yield and benefits of summer maize were investigated by split-plot design.The results showed that the yield was significant correlated with fertilization and density.The interaction effects of fertilization and density was obvious.The plant means of the best benefits and yield with 629.58 kg/667m2 were 30.4 kg/667m2 as topdressing nitrogen and 4 000 plant/667m2 as plant density.
