12 Nov 2026
Author:  No Comments

A warm and dry spring got our corn (and soybean) trials in earlier than ever in 2026.  Good rains in May and June sat us up for some really productive yield scenarios and quality trial data.

This year, we looked at 29 corn hybrids, grouped in 3 Relative Maturity classes

Early ≤ 113 day                               14 Locations

Medium 114-116 day                   23 Locations

Full ≥ 117 day                                 16 Locations

Thank you to our County Agents and producers across the state that put these trials in.  If you have any questions, please reach out to your County Extension Office.

Early Corn – CST

Medium Corn – CST

Full Corn – CST

All of this data along with OVT reports and disease/fungicide ratings will be available soon at utcrops.com

GR Palmer in Newly Cut Corn

Palmer amaranth is very apparent in newly cut corn fields. Just this past year some of our worst glyphosate-resistant Palmer infested soybean and cotton fields were in corn the previous year.  In most cases the Palmer amaranth that produced the seed emerged late as the corn was drying down.  Often the worst Palmer patches come up in July in partially drowned out areas in a given corn field.  Palmer that emerges in July in these areas is often 3 to 4’ tall by harvest time and will easily produce thousands of Palmer seed that will be a problem next year.
