Other claims from this paper (15)
- Intervention effect Irrigated wheat in rotations yielded 26% more than dryland wheat.
- Intervention effect Rainfall eliminated irrigation benefits for grain sorghum in 1989 and 1990.
- Intervention effect Irrigated sorghum rotation yield was 168% above dryland in 1991.
- Intervention effect Continuous irrigated sorghum yielded 8% less than rotated irrigated sorghum.
- Intervention effect Annualized continuous wheat yield was 20% above irrigated rotation yield.
- Intervention effect Annualized continuous sorghum yield was 59% above irrigated rotation yield.
- Intervention effect Annualized irrigated rotation yield resembled dryland yield in 1990.
- Intervention effect Annualized irrigated rotation yield exceeded dryland by 68% in 1991.
- Intervention effect Irrigating either rotation crop gave similar annualized yields.
- Intervention effect Irrigating both rotation crops added 13% yield.
- Observation Irrigation water-use efficiency was highest in rotated crops.
- Observation Irrigation water-use efficiency was lowest in continuous crops.
- Intervention effect Limited irrigation produced more grain than dryland systems.
- Recommendation Producers with less water should irrigate fallow systems.
- Recommendation Producers with more water can crop more intensely.
