- Intervention effect Ibrahim-equation watering reduced rice plant height by 5.02% in the first season.
- Intervention effect Ibrahim-equation watering reduced rice plant height by 6.97% in the second season.
- Intervention effect Reducing watering to 0.75 of traditional reduced grain yield by 33 kg/fed in the second season; the difference was not significant.
- Intervention effect Reducing watering to the Ibrahim-equation level reduced grain yield by 673.5 kg/fed (14.55%) in the first season, a highly significant difference.
- Intervention effect Reducing watering to the Ibrahim-equation level reduced grain yield by 630 kg/fed (13.91%) in the second season, a highly significant difference.
- Intervention effect In Egyptian hybrid 1, grain/straw ratio decreased as watering level decreased.
- Observation Mean 1000-grain weight of Giza 177 was 25.68 and 25.82 gm in the first and second seasons.
- Observation Mean 1000-grain weight of Egyptian hybrid 1 was 24.45 and 24.88 gm in the first and second seasons.
- Intervention effect With Giza 177 in the first season, watering at 0.75 of traditional gave higher grain weight per panicle (3.310 gm) than traditional watering (3.055 gm) and Ibrahim-equation watering (2.685 gm).
- Intervention effect With Giza 177 in the second season, watering at 0.75 of traditional gave higher grain weight per panicle (3.275 gm) than traditional watering and Ibrahim-equation watering.
- Intervention effect With Egyptian hybrid 1 in the first season, traditional watering gave higher grain weight per panicle (4.385 gm) than 0.75 of traditional (4.025 gm) and Ibrahim-equation watering (3.600 gm).
- Intervention effect With Egyptian hybrid 1 in the second season, traditional watering gave higher grain weight per panicle (4.540 gm) than 0.75 of traditional (4.165 gm) and Ibrahim-equation watering (3.595 gm).
- Observation Grain/straw ratio was 0.700 for Giza 177 and 0.980 for Egyptian hybrid 1 in the first season, and 0.770 and 0.952 in the second season.
- Observation Giza 177 had the lower crop water productivity (0.747 and 0.718 kg/m3).
- Observation Egyptian hybrid 1 had the higher crop water productivity (0.895 and 0.852 kg/m3).
- Observation Crop water productivity in the first season was 0.705, 0.850 and 0.908 kg/m3 for traditional, 0.75 of traditional and Ibrahim-equation watering.
- Observation Crop water productivity in the second season was 0.703, 0.833 and 0.820 kg/m3 for the same treatments.
