Effect of Density and Fertility on Yield and Its Component Factors of Long Spike Wheat 86(306)

In order to understand the impact of density and fertility to yield and its factors for long spike wheat 86(306),4 density levels and 4 fertilities levels were used.The result showed under the density 3.45 million/hm~2 and fertilizing N:315 kg/hm~2,P_2O_5:240 kg/hm~2,the yield got maximum value among different treatments;its factor spikes/hm~2,kernel numbers per ear and 1000-kernel weight got maximum value under different treatments of the density 3.45 million/hm~2 with fertilizing N:315 kg/hm~2,P_2O_5:240 kg/hm~2,the density 1.20 million/hm~2 with N:415 kg/hm~2,P_2O_5:240 kg/hm~2 and the density 3.45 million/hm~2 and fertilizing N:315 kg/hm~2,P_2O_5:240 kg/hm~2.
