The Arkansas Corn Standardized County Hybrid Trials is a collaborative effort between growers, County Extension agents, Extension specialists, and industry representatives to increase knowledge on selected hybrids that are being evaluated in the University of Arkansas Corn Hybrid testing program (http://arkansas-variety-testing.uark.edu/). In the trials, producers followed their normal production practices they use on their farms. The cooperation of all producers mentioned in this publication is appreciated. Producers donate time, equipment and hired labor to make these trials possible.
