Other claims from this paper (18)
- Observation DeKalb 63-42 was more tolerant to clethodim than 60-18 and 60-18F2.
- Observation Hybrids and their F2 progeny did not differ in responses to clethodim or glufosinate.
- Intervention effect Low N reduced clethodim injury compared with high N.
- Intervention effect Low N reduced glufosinate injury compared with high N.
- Association Earlier planting made glyphosate-resistant corn harder to control in replant situations.
- Intervention effect Clethodim (51 g ai ha−1) applied 6 days prior to replanting controlled initial corn stands by 96 to 100% and produced highest yield.
- Intervention effect glufosinate (450 g ai ha−1) applied at replanting along with a sequential treatment 3 weeks later controlled initial corn stands by 96 to 100% and produced highest yield.
- Recommendation Initial stands at or below 40,000 plants per hectare required replanting with stand control.
- Recommendation Initial stands at or above 60,000 plants per hectare did not require replanting.
- Observation An initial stand of 20,000 plants per hectare contributed 20% more yield than the replant stand.
- Recommendation The initial stand should be removed to maximize replant corn yield.
- Intervention effect High volunteer corn density reduced hybrid corn dry weight, N accumulation and grain yield at 200 kg N per hectare.
- Intervention effect Volunteer corn density did not affect total grain yield when volunteer yield was included.
- Intervention effect At 0 and 67 kg N per hectare, volunteer corn density did not affect hybrid dry weight or N accumulation.
- Intervention effect At 0 and 67 kg N per hectare, high volunteer corn density reduced hybrid and total grain yield.
- Intervention effect N fertilizer application timing had no effect on hybrid corn dry weight, N accumulation or grain yield.
- Intervention effect Late N fertilizer applications resulted in greater volunteer corn N accumulation, grain yield and total yield.
- Recommendation Management should reduce volunteer corn presence in corn.
