Abstract

A field experiment was carried out in 2009 to find out the most suitable density of new corn variety Zhengdan528.The developmental stages,plant height,ear characters and yield components of Zhengdan528 were analyzed under 7 planting densities.The results showed that the optimum density of Zhengdan528 was 52500-60000 plants/ha,but it could reach to 67500 plants/ha in abundant fertilizer and water conditions.
