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 High-rate ethephon increased grain yield per ear by 3% in hybrid 3377.
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%.

Shigeo MATSUMOTO; Ryoichi MATSUNAGA; Tadahiko FURUYA; et al. Japanese Journal of Crop Science 1982. doi:10.1626/jcs.51.293

Other claims from this paper (15)

Observation Fertilizer responses in vegetative growth and seed yield varied by soil, dramatically in sandy soil and slightly in upland and paddy soils.
Observation Both soybean species had low harvest indices in nutrient-poor sandy soil.
Observation Harvest indices were high in upland and paddy soils.
Observation Akisengoku had a higher harvest index than K-01 in upland and paddy soils.
Association Harvest indices in both soybean species declined above line-specific total top dry weights.
Intervention effect Akisengoku showed better vegetative growth response to nitrogen at an early stage.
Association At flowering, no relation between nitrogen and Akisengoku vegetative growth was recognized.
Intervention effect K-01 showed little or no growth response to nitrogen regardless of stage.
Intervention effect Nitrogen application had no significant effect on Akisengoku seed yield and yield components.
Intervention effect The highest nitrogen treatment decreased K-01 seed yield and yield components.
Intervention effect Nitrogen inhibited early nodulation in both soybean species.
Observation Early nodulation inhibition was greater in K-01 than Akisengoku.
Intervention effect Later Akisengoku nodulation under nitrogen was comparable to no nitrogen treatment.
Intervention effect Later K-01 nodulation in the highest nitrogen treatment was worse than with other treatments.
Mechanism The authors attribute reduced K-01 seed yield under the highest nitrogen treatment to impaired nodulation.
