  • Multiple entries: Use COPY option in the online system to duplicate an entry to avoid having to re-enter the same information for multiple fields. All copied information must be reviewed for accuracy. The following questions will not carry over from one entry to the next and must be filled out to submit the entry:
    • Class
    • Hybrid Brand
    • Hybrid Number
    • Date Planted


  • Sales reps who created a login in 2015 will be able to access the history of who they entered last year, allowing them easy access to complete the growers’ NCYC entry form.


  • Membership numbers cannot be searched for online. Please call NCGA 636-733-9004


  • Entry forms must be submitted to NCGA through the online entry form two weeks prior to the plot being harvested.


  • Supervisor signature approval validating the row lengths must be uploaded and attached online to the harvest form along with the signed weigh ticket.


  • The questions regarding non-contest acres has been removed from the harvest form and has been replaced with: Are the contest plot input volumes representative of the non-contest acres planted.


  • If a recheck is required, the recheck questions will appear immediately after the initial check information is completed. If a recheck is not performed and completed, the harvest form will not submit.


  • National Winners, as listed on the winning entry, are encouraged to accept their award and recognition in person during the NCGA NCYC Banquet during Commodity Classic. The only person who may accept the award in lieu of the actual winner is the designated representative of the seed company associated with that entry.

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 2017 Commodity Classic, state winners will be recognized at the NCYC Breakfast and national winners will receive awards at the Awards Banquet.


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.
