e0“strip tillage and no tillage had numerically greater grain yields than conventional tillage in all four years [approx. 8.1% and 6.4% (1.11 and 0.88 Mg/ha), respectively, for the four-year average], strip tillage was significantly greater in only two years”

Other claims from this paper (11)
- Intervention effect Corn yield increased about 10% from minimum to maximum irrigation capacity.
- Intervention effect No tillage had numerically greater grain yield than conventional tillage, significantly so in one year.
- Intervention effect Strip tillage tended to increase seasonal crop water use relative to conventional tillage and was significantly greater in two years.
- Intervention effect No tillage tended to increase seasonal crop water use relative to conventional tillage and was significantly greater in one year.
- Intervention effect Strip tillage tended to increase water productivity relative to conventional tillage in three of four years.
- Intervention effect No tillage tended to increase water productivity relative to conventional tillage in three of four years.
- Intervention effect Increasing plant density from 66,300 to 82,300 plants per hectare generally raised grain yield by about 6%.
- Intervention effect Increasing plant density from 66,300 to 82,300 plants per hectare generally raised water productivity by about 6%.
- Mechanism The authors suggest strip tillage retains residue benefits while reducing evaporation without a yield penalty.
- Recommendation The authors recommend strip tillage as an improved alternative to conventional tillage when irrigation capacity is limited.
- Recommendation The authors recommend no tillage as an improved alternative to conventional tillage when irrigation capacity is limited.
