In 2016, the University of Vermont Extension Northwest Crops and Soils Program evaluated yield and quality of 43 long season corn silage varieties at Borderview Research Farm in Alburgh, VT. Long season corn can be difficult to grow in Vermont due to limited Growing Degree Days (GDDs) accumulating through the growing season. In addition, wet springs and falls are common across Vermont, delaying corn planting and complicating harvest timing. Late harvest can also reduce the chances of timely fall manure applications and planting of cover crops. However, if planted early, long season corn can produce high yield and quality forage by maximizing the entire growing season. While the information presented can begin to describe the yield and quality performance of these long season corn silage varieties in this region, it is important to note that the data represent results from only one season and one location. Compare other hybrid performance data before making varietal selections.
