Hamilton County CGA Plot Results

The growing season was generally good, however several high wind events in October did cause some broken stalks and dropped ears. So to document the damage, dropped ears were counted after harvest by simply counting the ears on the ground between the middle two rows of the plot for a distance of 100 ft. and recording the numbers. Some hybrids had a lot of broken stalks but the combine was able to pick most of them up and recover the ears.
