El Niño peaks during the late fall or early winter months, and while it is not predictive of U.S. corn and soybean yields, it can affect the weather.
Weeds are detrimental to corn because they undermine crop formation and uniformity, particularly in the early stages of corn’s development, leading to a negative impact on yield.
URBANA, Ill. — U.S. corn and soybean varieties have become increasingly heat and drought resistant as agricultural production adapts to a changing climate. But the focus on developing crops for extreme conditions has negatively affected performance under normal weather patterns, a University of Illinois study shows. “Since the 1950s, advances in breeding and management practices […]
University of Illinois scientists definitively established the relationship between soil nitrogen at different growth stages and corn yield.
MU Extension agronomist Bill Wiebold’s research dispels concerns that yields decrease when smaller, later-emerging plants compete for nutrients and sunlight
Corn growers nationwide achieved impressive yields despite weather-related adversity in the National Corn Growers Association 2018 National Corn Yield Contest. The 18 winners in six production categories had verified yields averaging more than 349 bushels per acre, compared to the projected national average of 178.9 bushels per acre in 2018. While there is no overall […]
A collaboration between Kansas State University and DuPont Pioneer Agronomy analyzing 30 years of corn plant population responses shows that as agronomic optimum plant density increased, the range for maximizing yields also widened. DuPont Pioneer has collected data on corn plant population responses and yield gains to provide better information on hybrids. From 1987 to […]
