- Intervention effect Bed planting gave the highest wheat grain yield, 2791 kg fed.-1, versus 2698 under flat planting in season one.
- Intervention effect Bed planting gave higher water productivity than flat planting in season one.
- Intervention effect Bed planting gave higher irrigation water productivity than flat planting in season one.
- Intervention effect Bed planting increased water productivity by 8.71% against basin planting at 45% depletion.
- Intervention effect Bed planting increased irrigation water productivity by 23.9% against basin planting at 45% depletion.
- Observation The same planting-method trend held in the second season.
- Intervention effect Bed planting used the least irrigation water, 1973 and 1983 m3fed.-1, versus basin planting at 45% depletion.
- Intervention effect Bed planting had the lowest water consumptive use, 1332 and 1335 m3fed.-1, at 45% depletion.
- Intervention effect Bed planting saved about 17.6% irrigation water against basin planting.
- Intervention effect At 45% depletion wheat grain yield was highest, versus lowest at 75% depletion.
- Intervention effect At 45% depletion water productivity was highest, versus lowest at 75% depletion.
- Intervention effect At 45% depletion irrigation water productivity was highest, versus lowest at 75% depletion.
- Intervention effect Irrigation at 45% depletion increased water productivity by 10.4% versus 75%.
- Intervention effect Irrigation at 45% depletion increased irrigation water productivity by 8.8% versus 75%.
- Intervention effect At 90 kg N fed.-1 wheat grain yield peaked at 3136 kg fed.-1 in season one.
- Intervention effect At 90 kg N fed.-1 wheat water productivity peaked at 2.28 kg m-3 in season one.
- Intervention effect At 90 kg N fed.-1 wheat irrigation water productivity peaked at 1.46 kg m-3 in season one.
- Intervention effect Lower nitrogen applications of 60 and 75 kg fed.-1 gave minimum grain yields in both seasons.
- Recommendation The authors recommend bed planting, 90 kg N fed.-1, and irrigation at 45% depletion for wheat yield and water productivity.
