Corn Hybrid Evaluations, Bonita, 1997

Results of two field studies are reported in this paper. One study had six Bt corn hybrids and a non-Bt check, the other had six non-Bt hybrids (including 3 experimentals) and a non-Bt check. Pioneer 33A14 was the highest yielding hybrid in the Bt study with a yield of 14548 pounds per acre. Its yield was 1000 pounds per acre higher than the next Bt hybrid and nearly 2000 pounds per acre higher than Pioneer 3162, the non-Bt check. In the non-Bt study, a Pioneer experimental yielded 15405 pounds per acre, nearly 2000 pounds per acre higher than the next highest hybrid
