Other claims from this paper (10)
- Intervention effect Micro-sprinkler irrigation with late and split N increased grain protein concentration by 8.6% compared with border irrigation.
- Intervention effect Micro-sprinkler irrigation with late and split N increased post-anthesis nitrogen accumulation by 42.5% compared with border irrigation.
- Intervention effect Micro-sprinkler irrigation with late and split N significantly increased fertilizer N use efficiency by 15.8% compared with border irrigation.
- Observation About 30.1% of nitrogen in mature grains came from topdressing under micro-sprinkler irrigation.
- Intervention effect The proportion of nitrogen from topdressing in mature grains was 80.6% higher under micro-sprinkler irrigation than under border irrigation.
- Observation The increase in nitrogen uptake under micro-sprinkler irrigation was mainly due to increased uptake in chaff and grains.
- Intervention effect Micro-sprinkler irrigation increased the concentrations of protein and its components in grains, especially storage protein.
- Intervention effect Micro-sprinkler irrigation increased wet gluten content, as a result of the higher protein concentrations.
- Intervention effect Micro-sprinkler irrigation did not significantly change grain processing quality parameters compared with border irrigation.
- Recommendation Micro-sprinkler irrigation management may simultaneously increase winter wheat grain yield, protein concentration and fertilizer N use efficiency and stabilise processing quality in the North China Plain.
