Other claims from this paper (10)
- Intervention effect Conventional tillage increased corn plant stand versus no-tillage in three of six years.
- Intervention effect Improved management intensity increased corn plant stand versus traditional intensity in three of three years.
- Intervention effect No-tillage increased seed number versus conventional tillage in four of six years.
- Intervention effect No-tillage increased biomass versus conventional tillage in one of six years.
- Intervention effect No-tillage increased biomass versus conventional tillage under traditional intensity.
- Intervention effect Corn height, seed weight and harvest index were unaffected by treatments but varied by year.
- Intervention effect Preplant and postharvest soil water, water use and water-use efficiency were unaffected by treatments but varied by year.
- Intervention effect No-tillage increased corn yield in below-average precipitation years versus conventional tillage.
- Intervention effect Reducing seeding rate and wheat stubble height increased corn yield.
- Recommendation Authors recommend no-tillage with reduced seeding rate and wheat stubble height for dryland corn production without affecting soil water.
