Other claims from this paper (9)
- Intervention effect CCC at ZGS 13 increased grains per spike.
- Intervention effect Ethephon at ZGS 30 raised tiller-derived spike density by up to 265%.
- Intervention effect CCC at ZGS 30 increased Leger grain yield by more than 10% in two years.
- Intervention effect The CCC yield increase was attributed to slightly more grains per spike.
- Intervention effect Ethephon at ZGS 39 reduced height and lodging.
- Intervention effect Ethephon at ZGS 39 reduced yield by up to 27%.
- Intervention effect Ethephon reduced grain number, main culm spikes, or grain weight.
- Recommendation The authors advise against early CCC or ethephon for grain production in short seasons with little lodging.
- Recommendation The authors advise caution with ethephon at the recommended lodging-control rate and stage.
