Corn yields topping 300 bushels during drought are testaments to genetics
Even in a drought-limited year, regional state winners in the National Corn Growers Association yield contest grouped around 300-bushels per acre yields. An Extension agronomist says the contest shows possibilities in modern corn genetics and the combination of optimal weather and input management.
The National Corn Growers Association Corn Yield Contest winner again topped 600 bushels per acre.
David Hula of Charles, City, Virginia, for the second time went over that mark, this time with 602.1694 bushels per acre.
There were 27 national winners in nine production categories, with verified yields averaging more than 376.76 bushels per acre, compared to a projected average of 177 bushels per acre national commercial yield.
In a year that started out in drought , top state yield winners in conventional, non-irrigated categories included North Dakota at 299.9 bushels per acre, Minnesota at 300 bushels per acre, South Dakota at 277.6 bushels per acre, and Iowa at 320.96 bushels per acre.
Clair Keene, North Dakota State University Extension agronomist in small grains and corn, called the results “definitely impressive.” It shows the “genetic potential of modern corn varieties, and there’s some value to that,” she said.
Keene noted that the contest reflects yield on a 10-acre plot, however, and so is “cherry-picked,” and the farmers are supplying “sufficient fertility, probably more than sufficient fertility.” Commercial farmers, of course, must consider the profitability of inputs. The results probably are associated with high rates of starter fertilizer, multiple in-crop fertilizer applications, and “squeaky-clean” pest control.
She said she’s impressed with 300-bushel yields, and a 600-bushel yield is a “really big jump,” from that. She said she is curious about the size of the ears, the number of kernels, the fill, and other statistics that produce such yields.
Keene said winners no doubt had a “season that is super, super conducive to good yields” with the “right humidity, warmth during pollination and never water-stressed before, during and after pollination,” as well as favorable harvest.
Besides as a curiosity, one big plus for the contest is that it connects farmers with the National Corn Growers Association, an advocacy group for the industry. “It’s an engagement tool; it’s a good thing,” she said.
