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.

      • Entrants and harvest supervisors are responsible for giving accurate row lengths for odd shape plots.

      • A total of 1.25 or more acres must be harvested.

      • All end rows/turning rows and the equal number of outermost rows on each side may not be a part of the selected 1.25 acre contest plot.

    ROW LENGTH: If the rows are all the same length, measure the length of one row and record the same length for each of the rows harvested. If the rows are not all the same length, measure down the center of each set harvested and record the length for each of the rows in the set. (On pivot irrigation do not subtract wheel space).

    ROW WIDTH: Record the row width based on spacing of the planter row units, such as 7.5”, 15”, 20”, 30”, 36”, 38”, etc.
