e0“Corn (Zea mays L.) yield reduction following winter wheat (Triticum aestivum L.) in no-till systems prompted a study on the effects of tillage and residue management systems on corn growth and seedbed conditions”

Other claims from this paper (12)
- Intervention effect No-till treatments required at least 2 more days to reach 50% corn emergence and 50% silking.
- Intervention effect No-till had the lowest corn biomass at 5 and 7 weeks after planting.
- Intervention effect Grain yield of fall moldboard plow treatments averaged 1.1 t ha −1 higher than no-till treatments (P < 0.05).
- Intervention effect Grain yield differences among moldboard plow treatments were insignificant regardless of residue amount or fall N application.
- Intervention effect Completely removing all wheat residue from NT plots reduced the number of days to 50% corn emergence.
- Intervention effect Completely removing all wheat residue from NT plots increased grain yield by 0.43 t ha –1 over baling.
- Intervention effect Completely removing all wheat residue from NT plots increased grain yield by 0.61 t ha –1 over not baling straw.
- Intervention effect Complete residue removal from NT plots still gave 8% lower grain yield than moldboard plow treatments.
- Intervention effect Early in the season, no-till plots without residue removal had lower soil growing degree days than moldboard plow (baled) treatment.
- Intervention effect No-till plots without residue removal had higher soil moisture in the top 15 cm than all other treatments.
- Intervention effect Fall application of 50 kg N ha −1 to no-till plots did not change soil NO3-N levels at planting.
- Association Corn response in no-till systems after wheat mostly depends on residue level.
