Intervention effect Dinoseb reduced corn yield by 18.0% on average in irrigated corn.
Intervention effect Dinoseb reduced corn yield by 18.4% on average in nonirrigated corn.
Mechanism Part of the dinoseb-induced yield loss may be due to reduced harvest index and reduced ear fill.
Intervention effect Triacontanol did not affect corn grain yield in six of eight comparisons with untreated plots.
Observation The irrigation × dinoseb interaction was significant in only one of six comparisons.
Intervention effect Triacontanol increased corn yield under irrigation.
Observation The hypothesized interaction of environmental stress with dinoseb and triacontanol was not substantiated.
Recommendation The inconsistent performance of these growth regulators should not be attributed to environmental conditions of the growing crop.
