Technical Abstract: Colorado State University (CSU) conducts hybrid corn performance trials to provide research-based, unbiased, current, and reliable information to Colorado corn producers to make better planting decisions. CSU promotes crop variety testing as a service to crop producers and seed companies who depend on us for crop variety performance information. The corn trials are made possible by funding received from company entry fees, the Colorado Corn Administrative Committee, and the CSU Agricultural Experiment Station. Colorado State University personnel planted six irrigated and two dryland corn grain trials in Colorado, in addition to two irrigated silage trials. Irrigated grain trial locations were Burlington, Holyoke, Rocky Ford, Sterling, Wiggins, and Yuma. Irrigated silage trial locations were Fruita and Rocky Ford. The dryland trials were located at Akron and Julesburg. All trials were harvested but results from the Akron location were not statistically significant due to field variation and drought. Sixty-four hybrids with diverse origins, maturities, and value-added traits were tested at the different irrigated and dryland trial locations. Trial results were statistically analyzed and reported shortly after harvest on our website at
