Joe Lauer, Corn Agronomist

The 1999 corn production season will be remembered as one of high yields and low prices. Grain yield at all testing locations for the Wisconsin Performance Trial program was greater than the 10-year average increasing between 13 and 73% (Table 1). Trial averages ranged from 147 to 222 bu/A for all hybrids tested. Yields were especially high in the northern production zones. Silage yield was also greater than the 10-year average with increases of 1 to 16 % (Table 2). Silage yields ranged from 7.5 to 10.1 Tons dry matter/A.
