With Delayed Corn Planting, Is It Time To Switch Maturities?

By Lisa Jasa - Former CropWatch Editor, Roger Elmore - Emeritus Extension Cropping Systems Agronomist, Jenny Brhel - Extension Educator

Figure 1. A research plot at the universityâs Eastern Nebraska Research and Extension Center (ENREC) near Mead on May 13, 2019. The entire plot is covered with no-till corn residue. The west half also is covered with a November 17 planted cereal rye cover crop. Soil temperatures 2 inches deep were recorded in each half, but were essentially the same, so are averaged in this report.
