Title

Other claims from this paper (6)
- Intervention effect At 200 kg N per hectare, high volunteer corn density reduced hybrid corn dry weight, N content and grain yield regardless of N timing.
- Intervention effect High volunteer corn density reduced hybrid corn grain yield by 19% at both 0 and 67 kg N ha −1.
- Intervention effect High volunteer corn density reduced total grain yield by 9 and 10% at the two N rates, respectively.
- Intervention effect Application timing of N fertilizer had no effect on hybrid corn dry weight, N content or grain yield.
- Intervention effect Late N fertilizer applications increased volunteer corn N content, volunteer corn grain yield and total yield.
- Recommendation A late N application can be used to reduce the competitive effects of volunteer corn in hybrid corn while maximizing total grain yield.
