Grain - Silage - Specialty - Organic

December 2016  A3653

Every year, the University of Wisconsin Extension-Madison and College of Agricultural and Life Sciences conduct a corn evaluation program, in cooperation with the Wisconsin Crop Improvement Association. The purpose of this program is to provide unbiased performance comparisons of hybrid seed corn available in Wisconsin. These trials evaluate corn hybrids for both grain and silage production performance. In 2016, grain and silage performance trials were planted at fourteen locations ... more

Corn Growth and Development Poster

June 2016

A poster for the shop showing critical growth stages for corn yield components. The poster was developed by Ignacio Clampotto (KS)., Roger Elmore (NE) and Joe Lauer (WI).
