- Intervention effect PGRs increased harvest index by 10%.
- Intervention effect PGRs did not affect aboveground biomass.
- Intervention effect Chlormequat chloride reduced plant height and lodging.
- Intervention effect Chlormequat chloride reduced mean seed yield.
- Association The effect of CCC on seed yield depended on climatic conditions.
