| Abstract: |
| Under the condition of natural precipitation of north Weihe River，the winter wheat variety Pubing143 was used to study the effect of fertilities, sowing date and densities of dryland wheat on its yield and components by split-plot design. The results showed that Pubing143 is a variety of drought and disease resistance, high yield, good quality and high adaptability. It had different optimal sowing date and density requirements in the three types of soil fertility. In order to achieve both high and stable yield, Pubing143 should be planted on the following condition——the medium level of fertilizer，the sowing date in about September 24 (Beiyuan in Qianxian County and similar areas), and the density of 160 000～200 000/667 m2. |
