An area corn grower has been honored as a state winner in the 2012 National Corn Yield Contest, sponsored annually by the National Corn Growers Association.

Adrian Cox of Trenton placed first in Missouri in the AA Non-Irrigated Class with a yield of 261.032 bushels per acre. The hybrid used in the winning field was Dekalb DKC64-69.

Cox was one of 421 state winners nationwide. The 2012 contest had 8,263 entries from 46 states. Of the state winners, 18 growers – three from each of six classes – were named national winners, representing 13 states. The average yield among national winners was 316.3 bushels per acre – greater than the 2012 U.S. average of 122.3 bushels per acre. Nine of the national winners recorded yields of 300 bushels or more per acre.

"Despite the fact that 2012 was a challenging production year, individual growers continued to provide a showcase for American production agriculture," said NCGA Chairman Garry Niemeyer, a corn grower from Auburn, Ill. "While the national corn yield average declined more than 24 bushels per acre in 2012, the average yield in this year's contest actually increased by more than three bushels per acre as compared to 2011."

"That's why this contest and its focus on safe, advanced corn production methods are so important," Niemeyer said.

The top yield in this year's contest was 384.4 bushels per acre achieved by David Hula of Charles City, Va.

Farmers are encouraged through the contest to utilize new, efficient production techniques. Agronomic data gleaned from the contest reveal the following:

Average planting population for the national winners was 37,941 seeds per acre, compared to 33,532 for all entrants.

National winners applied an average of 273 pounds of nitrogen, 82 pounds of phosphorus and 115 pounds of potassium per acre.

Average commercial nitrogen use per bushel of yield was 0.87 pounds for the national winners and 0.90 pounds for all entrants.

Fifty percent of the national winners applied trace minerals, compared to 36 percent of all entrants.

Use of manure as a fertilizer was consistent. Seventeen percent of national winners applied manure, compared to 16 percent of all entrants.
