Entries with an Asterisk (*): National Corn Yield Contest rules state that each individual membership is eligible to win only one national and one state trophy in the contest. If an entrant enters two or more hybrids and all place as a winner or runner-up, a trophy will be awarded only for the highest ranked (not necessarily highest yield) hybrid. We use the asterisk (*) to indicate that there is an entry under the same membership number that has placed higher and been awarded a trophy, which in turn knocks out the asterisked entries from being awarded a trophy.


For nearly a half century, NCGA’s National Corn Yield Contest has provided corn growers the opportunity to compete with their colleagues to grow the most corn per acre, helping feed and fuel the world. This has given participants not only the recognition they deserved, but the opportunity to learn from their peers.


Winners receive national recognition in publications such as the NCYC Corn Yield Guide, as well as cash trips or other awards from participating sponsoring seed, chemical and crop protection companies. In San Antonio, Texas, during the 2014 Commodity Classic, state winners will be recognized at the NCYC Breakfast and national winners will receive awards at the Awards Banquet.
