Other claims from this paper (15)
- Intervention effect Irrigation treatments differed significantly at the 1% level in tiller number, panicle length and filling percentage of rice.
- Intervention effect Irrigation management had no significant effect on rice plant height and grain yield.
- Intervention effect Traditional flood irrigation gave the maximum rice yield of 6.11 ton/ha.
- Intervention effect Alternate irrigation five days after water disappearance (AI5) gave a rice yield of 6.02 ton/ha, slightly lower than TI.
- Observation Applied irrigation water under TI was 7,940 m3/ha.
- Observation Applied irrigation water under AI1 was 4,910 m3/ha.
- Observation Applied irrigation water under AI3 was 4,090 m3/ha.
- Observation Rice water productivity under TI was 0.82 kg/m3.
- Observation Rice water productivity under AI1 was 1.05 kg/m3.
- Observation Rice water productivity under AI3 was 1.38 kg/m3.
- Observation Rice water productivity under AI5 was 1.83 kg/m3.
- Intervention effect Irrigation treatments differed significantly at the 1% level in rice water productivity.
- Recommendation Alternate irrigation five days after surface water disappearance (AI5) is recommended as the best irrigation practice for rice.
- Intervention effect Alternate irrigation five days after surface water disappearance (AI5) reduced rice water use by 56.07% relative to control treatment.
- Intervention effect Alternate irrigation five days after surface water disappearance (AI5) reduced rice grain yield by only 1.47% relative to control treatment.
