Other claims from this paper (9)
- Intervention effect At 85% ETc, rice yield matched full irrigation at 6.2 t/ha.
- Intervention effect The 85% ETc treatment used 15% less water than full irrigation.
- Intervention effect The 85% ETc treatment had higher rice crop WUE of 1.18 kg/m3 than full irrigation at 1.03 kg/m3.
- Intervention effect The 70% ETc treatment had the highest rice crop water use efficiency, at 1.31 kg/m3.
- Intervention effect Rainfed treatment had among the lowest rice yields and crop WUE values.
- Intervention effect Farmer practice treatment had among the lowest rice yields and crop WUE values.
- Recommendation The authors conclude that moderate deficit irrigation can maintain high rice yields and substantially increase water productivity.
- Observation The Chauru Irrigation Scheme showed technical efficiency in water delivery and yield support under controlled experiments.
- Mechanism The authors attribute suboptimal WUE in farmer plots to irrigation timing, uneven distribution, and lack of a followed schedule.
