Title

Use of Ethephon as a Plant Growth Regulator in Corn Production

J. M. Gaska; E. S. Oplinger Crop Science 1988. doi:10.2135/cropsci1988.0011183x002800060024x

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 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%.
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.

Other claims from this paper (7)

Association Yield response to elevated CO2 correlated strongly with increased symbiotically fixed N between R5 and R8.
Intervention effect Elevated CO2 caused small increases in fertilizer-derived N uptake from R5 to R8.
Intervention effect Elevated CO2 caused small increases in soil-derived N uptake from R5 to R8.
Association Increases in fertilizer-derived and soil-derived N uptake did not correlate with enhanced yield.
Intervention effect Elevated CO2 reduced the proportion of seed N redistributed from shoots to seeds.
Association Total N uptake was associated with increased fixed N per nodule under elevated CO2.
Association Total N uptake was not associated with changes in nodule biomass, density or root length.
