e1“The results indicated an improved water productivity of all crops under NT compared with that of CT”
e2“the response of cereals (corn +1.0 kg ha−1 mm−1, wheat +1.3 kg ha−1 mm−1) was higher than that of sunflower (+0.3 kg ha−1 mm−1) and soybean (+0.5 kg ha−1 mm−1)”

Other claims from this paper (14)
- Intervention effect No-till improved the water productivity of all crops compared with conventional tillage.
- Intervention effect Under NT, corn water productivity rose by +1.0 kg ha-1 mm-1 relative to CT.
- Intervention effect Under NT, wheat water productivity rose by +1.3 kg ha-1 mm-1 relative to CT.
- Intervention effect Under NT, soybean water productivity rose by +0.5 kg ha-1 mm-1 relative to CT.
- Association The water productivity response of cereals was higher than that of sunflower and soybean.
- Association Crop type had a larger effect on water productivity than the tillage system.
- Observation Corn water productivity was 9.8 kg ha-1 mm-1.
- Observation Wheat water productivity was 6.9 kg ha-1 mm-1.
- Observation Soybean water productivity was 2.4 kg mm-1, lower than cereals.
- Observation Sunflower water productivity was 3.9 kg mm-1, lower than cereals.
- Observation Economic water productivity of sunflower (0.9 US$ ha-1 mm-1) almost equalled that of wheat.
- Observation Economic water productivity of wheat was 1.1 US$ ha-1 mm-1.
- Observation Economic water productivity of corn was 1.2 US$ ha-1 mm-1.
- Recommendation Combining no-till with water-efficient crops could be a promising step toward improving food production in semiarid regions.
