Effects of Planting Density and Fertilization on Yield of Qiandan 24

Tang Guang-shu

Abstract

Quadratic regression orthogonal rotational and single-factor randomized block design were adopted,and effects of planting density,fertilization and seed coating on main agronomic traits and yield were researched in order to support techniques for high-yield cultivation of hybrid maize cultivar,Qiandan24.The results showed that the optimized cultivation techniques of Qiandan 4for high-yield were that the planting density,N fertilizer,P fertilizer and K fertilizer were 4170-4294plants/667m2,22.78-25.7kg/667m2,13.75-16.25kg/667m2 and 9.335-11.005kg/667m2,respectively.
