Other claims from this paper (10)
- Intervention effect AWD plots received on average 57% less irrigation water than continuously flooded plots.
- Intervention effect Rice yields did not significantly differ between AWD and continuous flooding.
- Intervention effect In the earlier flowering, more vigorous CH-45, there were no treatment differences in any yield component.
- Intervention effect In the later flowering Hardinath-1, AWD decreased filled grain number by 11%.
- Intervention effect Leaf elongation rate on the main tiller did not differ between irrigation treatments.
- Intervention effect Tillering and green fraction were significantly higher under AWD.
- Intervention effect The authors infer that AWD could considerably enhance crop water use efficiency in this region.
- Observation Surveys established that most local farmers already use a local adaptation of AWD to modify irrigation volumes.
- Observation Farmers have few direct incentives to reduce overall water use under current water governance.
- Observation Formal AWD practices are therefore unlikely to be adopted by smallholder farmers.
