This is especially true in terms of assessing the relative maturity of the hybrids as grain moisture at harvest may not be a reliable guide to hybrid maturity. At all locations, some hybrids died prematurely because of weather stresses and diseases. Hybrid selection should be based on the most data available. Greater emphasis should be put on averages from several locations which provide a more accurate prediction of future performance than will single location results. Many corn growers will receive a copy of the Performance Trials Report with their December issue of The Ontario Corn Producer magazine.
Reports are also available from some seed corn dealers and some farm supply outlets.
