Any corn production system can be entered in the contest. WCGA is not responsible for incorrect or missing entries. All rules set forth herein apply to all entries. Three winners will be selected from each of five geographical divisions in the state. Divisions are based on active county corn grower organizations. Active county organizations include those that have met at least twice during the calendar year.


There is no cost to enter, but the entrant must be a Wisconsin Corn Grower Association member in good standing. Only one entry per membership, but there could be more than one entry per farm if additional memberships are purchased.


Contest field must be in the state of Wisconsin. Contest entry must be at least 10 continuous acres of one variety. Contestant may select the best 1.25 acres in a corn field larger than 10 acres and enter that variety. In the interest of Best Management Practices, grass waterways may be a part of the contest plot area. The length of any rows planted in a grass waterway will be included in the harvested row length if corn rows are planted in the waterway. If corn rows are not planted in the waterway, the length of each row will not include areas in the waterway. The land entered in the Contest must be owned or leased by the entrant and located in Wisconsin. The variety entered must be currently commercially available.
