e0“The objective of this study was to determine the effect of ethephon on four hard red spring wheat cultivars in North Dakota environments”
e7“Economic parameters, net benefit, and marginal rate of return, indicated ethephon could be recommended for cultivars Era, Len, and Stoa, but not for Nordic under environmental conditions similar to those in this study”

Other claims from this paper (8)
- Intervention effect Ethephon application increased grain yield by 5.4% averaged across environments and cultivars.
- Intervention effect Ethephon tended to increase the number of spikes per square meter.
- Intervention effect Ethephon had no effect on kernel weight and kernels per spike.
- Intervention effect Ethephon treatment reduced lodging in 1987.
- Observation Lodging was absent in 1988.
- Intervention effect Ethephon application had a significant positive effect on test weight compared with the control.
- Intervention effect Ethephon did not influence grain protein concentration or maturity.
- Recommendation Net benefit and marginal rate of return indicated that ethephon could be recommended for cultivars Era, Len and Stoa.
