Relationship among Planting Density,Yield and Yield Components of Luoyu No.8

The relationship among planting density,maize yield and yield components of Luoyu No.8 was studied.The results revealed that planting density has greatest influence on plant height,then significant influence on 1000-grains weight and grain number per row,but non-significantly influence on ear length and ear row number.Planting density is the key factor to influence yield of maize,which means the best planting density of Luoyu No.8 in Yuxi district and other similar areas is not over 78 755 shoots/hm2.
