Other claims from this paper (11)
- Intervention effect Chlormequat application reduced wheat crop height in all trials.
- Observation Crop lodging did not occur in any chlormequat trial.
- Observation Statistically significant grain yield responses to rate of application alone occurred in only three of 24 trials.
- Observation Maximum grain yield occurred at 0.19-0.37 kg/ha a.i. of chlormequat.
- Observation Some indication of yield depression occurred at 0.75 kg/ha a.i. of chlormequat.
- Observation A significant effect of time of application on grain yield was observed in only two trials, with conflicting results.
- Observation In one trial, the response to chlormequat rate occurred only at the 6-leaf stage.
- Observation No differences were detected between chlormequat formulations.
- Observation Averaged over all trials, chlormequat treatments yielded 102.5, 99.3 and 100.0% of the control in the three years.
- Intervention effect Low chlormequat application rates applied early in crop development can increase wheat grain yield.
- Recommendation Chlormequat is not recommended for increasing wheat grain yield under natural rainfall in south-western Australia.
