Hybrid selection has one of the biggest influences on yield. University of Minnesota Extension Corn Agronomist Jeff Coulter says the yield differences between corn hybrids range from 30-to-50 bushels per acre or more. During the University of Minnesota Crop and Pest Connect, Coulter advised farmers to choose two-to-three hybrids in two-to-three different maturity groups. “Within these maturity groups, the idea is to choose hybrids that have high and stable yield, lower grain moisture and less stalk lodging.” Other factors for hybrid selection include emergence and early season vigor, root strength and tolerance to insect pests and diseases.
