Other claims from this paper (11)
- Intervention effect No-tillage corn had lower plant populations than moldboard plow in seven site-year comparisons.
- Intervention effect No-tillage corn had lower grain yields than moldboard plow in five of 12 site-year comparisons.
- Intervention effect Ridge tillage corn had lower plant populations than moldboard plow in five comparisons.
- Intervention effect Ridge tillage corn had higher or similar grain yields than moldboard plow in the other 10 comparisons.
- Intervention effect Moldboard plow had higher equipment costs than no-tillage and ridge tillage.
- Intervention effect Moldboard plow had higher labor costs than no-tillage and ridge tillage.
- Intervention effect No-tillage had higher herbicide and grain-drying costs in most site-year comparisons, offsetting lower equipment and labor costs.
- Intervention effect No-tillage had higher variable production costs than moldboard plow at two sites.
- Intervention effect No-tillage was economically competitive with moldboard plow at the well-drained site, with break-even prices of $1.58 and $1.55/bu.
- Intervention effect No-tillage was economically competitive with moldboard plow at the poorly drained sites, with break-even prices of $2.08 and $2.16/bu.
- Observation Ridge tillage was economically competitive at all sites.
