ST. LOUIS (March 10, 2019) – The backbone of agriculture in the U.S. continues to be the American farmer.
As they strive to meet the growing demand for corn to satisfy increasing world need, one area grower has been honored through the 2018 National Corn Yield Contest. The national contest, sponsored annually by the National Corn Growers Association, recognizes farmers from across the country for their exceptional efforts.
Nolan Clark of Mer Rouge, LA placed Third in the state in the I: Irrigated Class with a yield of
266.0523 bushels per acre. The hybrid used in the winning field was DEKALB DKC70-27. The winning field was located in LA.
Nolan Clark was one of 417 state winners nationwide. The 2018 contest participation included
7,258 entries from 46 states. Of the state winners, 18 growers – three from each of six classes – were
named national winners, representing eight states.
The average yield among national winners was more than 349 bushels per acre – greater than the
projected 2018 U.S. average of 176.6 bushels per acre. One national winner recorded a yield of over 475 bushels per acre topping out at an astounding 477.6877 bushels per acre which was achieved by Don Stall of Charlette, MI.
“In 2018, corn farmers showed, yet again, that they continually grow an abundance that feeds and
fuels the world sustainably,” said NCGA President Lynn Chrisp, a corn grower from Hastings, Nebraska.
“The NCGA NCYC contest participants exhibited the potential of all America’s farmers as they
continually adopt innovative tools which help them achieve excellence,” Chrisp continued. “Their
incredible achievements, from averaging more than 349 bushels per acre amounts all national winners to a top yield of 477.6877, clearly showed the ability of America’s corn farmers to excel even facing less-than- ideal conditions.”
Farmers are encouraged through the contest to utilize new, efficient production techniques.
