Advanced production techniques, informed growing practices, improved seed varieties—corn growers put everything they know into achieving the highest yields in the National Corn Growers Association National Corn Yield Contest. Winners receive national recognition in publications such as the NCYC guide, as well as awards from participating sponsoring seed, chemical and crop protection companies. After each contest, a group of NCGA corn growers review NCYC rules and approve changes to streamline contest entry and to ensure the accuracy, integrity and credibility of the harvest process. To participate as an NCGA contest supervisor, please call the NCGA office at (636) 733-9004 for more information.
South Dakota Corn had a showplot program for a number of years, comparing the performance of various hybrids grown side-by-side on farms. A variety of seed companies participated in the program.
