Other claims from this paper (10)
- Intervention effect Ethephon increased yields of hybrid 3377 up to 280 g ha −1.
- Intervention effect Other tested corn hybrids showed decreased yields under ethephon.
- Intervention effect Hybrid 3377 yield increased 0.77 Mg ha −1 (7.6%) with 280 g ha −1 in 1985.
- Intervention effect Early ethephon application caused less yield decrease than later application.
- Intervention effect High-rate ethephon decreased grain yield per ear by 12% in hybrid 3737.
- Intervention effect High-rate ethephon decreased plant and ear height by up to 20%.
- Intervention effect High-rate ethephon decreased lodging by 63% in 1986.
- Intervention effect High-rate ethephon decreased harvesting time by 20% in 1986.
- Recommendation Under lodging-prone conditions, the authors suggest high-rate early ethephon may preserve yield and ease harvesting.
- Recommendation Without lodging, high-rate late ethephon may reduce yield in some hybrids.
