The corn silage hybrid evaluation program expanded to 77 hybrids in 2018. Hybrid evaluation at multiple environments helps in decision making and expands the reach of this type of data to more farmers. With this in mind Cornell, UVM, and seed companies collaborate to bring this robust evaluation. This year, hybrids were either entered into the 80-95 day relative maturity (RM) group (Early-Mid) and were tested at two locations in NY (n = 20; Hu-Lane Farm in Albion and the Willsboro Research Farm in Willsboro) and one location in VT (n = 20; Borderview Farm in Alburgh) or were entered into the 96-110 day relative maturity group (Mid-Late) and were tested at two locations in NY (n = 57; Greenwood Farms in Madrid and the Musgrave Research Farm in Aurora) and one location in VT (n = 55; Borderview Farm in Alburgh). The average Growing Degree Days (GDD; 86-50°F system) from May through August for years 2005 to 2018 is 2053 GGD at Albion, 2039 at Willsboro, 1979 at Alburgh, 2078 at Aurora and 1953 at Madrid (Table 1a and 1b).
