Other claims from this paper (12)
- Intervention effect No tillage doubled corn yield in 1991.
- Intervention effect No tillage increased corn yield by 41% in 1994.
- Intervention effect Early and late May planting gave the highest yields in 1991.
- Intervention effect Early and mid May planting usually gave the highest yields in other years.
- Association Yield declined as population increased in 1991.
- Association Yield usually rose with population in other years.
- Intervention effect P3 increased average yield over P1 by 41% with no tillage in 1992 and 1993.
- Intervention effect P3 increased average yield over P1 by 28% with conventional tillage in 1992 and 1993.
- Intervention effect No tillage usually produced the most grain with P2 in 1994.
- Intervention effect Population increases did not increase conventional tillage yield in 1994.
- Recommendation The authors recommend early to mid May planting at no more than 18,000 plants per acre.
- Recommendation The authors consider no tillage essential in dry years and beneficial in more favorable years.
