David Hula of Charles City, Virginia had a yield of 616.1953 bushels per acre this year, a record for the National Corn Growers Association's annual contest. 

This is the 55th year of the National Corn Yield Contest. 

“Yield contest participants create and share information that shapes the future of the industry while participating in friendly competition,” said Roger Zylstra, chair of NCGA’s Stewardship Action Team. “At both the state and national levels, contest winners find new ways to excel in a variety of situations. In turn, these innovations can help their fellow farmers face challenges as well. Our contest emphasizes invention and improvement, both from growers and technology providers, that enables U.S. farmers to meet the growing demand for food, feed, fuel and fiber.”

Overall, the contest featured 27 winners across nine production categories. Their yields averaged around 383 bushels per acre. 

There are no overall winners, just winners in each category and those winners received cash trips or other awards from sponsoring seed, chemical and crop protection companies. They will also be honored during the Commodity Classic in San Antonio.

"As the contest brings together farmers to create and innovate for the good of the industry, NCGA’s grassroots efforts create positive change and real opportunities by amplifying the impact of each member's voice as they join together,” said Brandon Hunnicutt, chair of NCGA’s Engaging Members Committee
