Results for the 2021 UCCE Delta field corn variety trial are now available. This annual trial takes place on Tyler Island. The trial was planted on April 20^th and included sixteen varieties submitted by seed companies and the cooperating grower. We evaluate varieties across three replicate blocks for performance under Delta conditions, including high organic matter soils and pest pressures typical for the region. Of note for 2021, Fusarium ear rot incidence was very low compared to previous years. The trial was harvested on October 1^st.

Twelve varieties yielded similarly well, based on statistical analysis, and varieties that yielded lower in the trial had a higher incidence of head smut disease. In addition to yield, there were also statistical differences in days to bloom, head smut, ear height, grain moisture, and bushel  weight. A table of results, as well as more information about the experimental design, data collection, and statistical analysis are available from the full report.
