Other claims from this paper (11)
- Intervention effect Two stages of supplementary irrigation significantly increased grain yield of dryland wheat by 895 kg ha-1.
- Intervention effect Two stages of supplementary irrigation significantly increased straw yield of dryland wheat by 2069 kg ha-1.
- Intervention effect Fall application of nitrogen increased grain yield of dryland wheat by 195 kg ha-1, though fall and split application had no significant effect on yield.
- Intervention effect Fall application of nitrogen increased nitrogen use efficiency (NUE) of dryland wheat by 1.97 kg.kg-1.
- Intervention effect Fall application of nitrogen increased water use efficiency (WUE) of dryland wheat by 0.5 kg.ha-1.mm-1.
- Intervention effect Nitrogen application increased the number of spikes per square meter more than the other grain yield components of dryland wheat.
- Observation The nitrogen requirement of dryland wheat under single irrigation at planting time was 70 kg ha-1, placed by fertilizer placement method.
- Observation The nitrogen requirement of dryland wheat under two-stage supplementary irrigation was 90 kg ha-1.
- Association Higher yield in the first year of the experiment was associated with higher precipitation.
- Association The interactions of irrigation, nitrogen rates, application times and genotypes had no significant effect on grain yield.
- Intervention effect Fall and split nitrogen application had no significant effect on yield and yield components of dryland wheat.
