2014 Wisconsin Corn Hybrid Performance Trials: Grain - Silage - Specialty - Organic


Every year, the University of Wisconsin-Extension and the University of Wisconsin-Madison 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 for both grain and silage available in Wisconsin.
In 2014, grain and silage performance trials were planted at 14 locations in four production zones: the southern, south central, north central, and northern zones. Both seed companies and university researchers submitted hybrids.

The 2014 planting season, like the 2013 season, was one of the longest ever recorded in Wisconsin. Frequent rains caused delays, with many growers in north eastern Wisconsin not planting until mid-June. Delayed planting at Coleman, Marshfield, Seymour, and Valders combined with a cool growing season delayed harvest producing grain that was higher in moisture and lower for test weight than average. Over the entire growing season, growing degree-day accumulation was below the 30-year normal in both northern and southern Wisconsin. During May and June precipitation was significantly above average throughout Wisconsin. Cold weather and snow occurred during early November affecting grain dry down at Coleman, Marshfield, and Seymour. Little insect or disease pressure was observed in the trials. Grain and silage yields were above normal compared to the 10-year average at early planted sites.
