Other claims from this paper (13)
- Intervention effect No-till did not consistently change soil temperature and moisture after planting compared with conventional tillage.
- Intervention effect No-till delayed corn emergence by 1 to 11 days compared with conventional tillage.
- Intervention effect No-till reduced plant vegetative dry weight at stage V6 by 20 to 60% compared with conventional tillage.
- Intervention effect No-till delayed silking by 5 days in 2 of 3 years compared with conventional tillage.
- Intervention effect Grain moisture was about 4 percentage points higher in 2 of 3 years under no-till.
- Intervention effect Grain yields were similar under no-till and conventional tillage in 1986.
- Intervention effect No-till reduced grain yield by 66 bu/acre compared with conventional tillage in 1985.
- Intervention effect No-till reduced grain yield by 25 bu/acre compared with conventional tillage in 1987.
- Association Short-season hybrids gave the greatest yields under both tillage systems.
- Intervention effect No-till reduced economic return by $8 to $156/acre compared with conventional tillage in all years.
- Intervention effect No-till increased pesticide costs compared with conventional tillage.
- Intervention effect Machinery and labor savings with no-till were offset by pesticide costs and lower yields.
- Recommendation Reduced tillage may be a better option than no-till for late-planted corn after hay harvest on rolling hillsides in the upper Midwest.
