MU research: Corn emerging in 1-week window has little impact on yield

COLUMBIA, Mo. – Research by University of Missouri Extension agronomists shows that there is little yield difference in unevenly emerged corn. MU Extension agronomist Bill Wiebold researched corn emergence’s effect on yield in 2010 and 2011. Wiebold tagged individual plants from emergence through harvest. He compared the weight and height of early-emerging, mid-emerging and late-emerging plants.

With freezing temperatures predicted, put the brakes on corn planting

COLUMBIA, Mo. – University of Missouri Extension agronomists caution that farmers should delay corn planting in light of predicted freezing temperatures.MU Extension grain crops specialist Greg Luce said on April 9 that “the very cold and very long cold spell in the week ahead could put newly planted corn seed at high risk of damage.”

MU Soil and Plant Testing Lab still open and serving Missouri agriculture

COLUMBIA, Mo. – For now, the University of Missouri Soil and Plant Testing Laboratory remains open.“We understand the essential role the lab plays in supporting Missouri's agricultural industry,” said Robert Kallenbach, MU Extension senior program director for agriculture and environment. “If we can continue to operate safely, the MU Soil Testing Laboratory in Columbia will continue to accept samples.”

Corn prices headed up?

The outlook for corn prices is more positive because corn is likely to experience a significant downward supply shock. Not only will planted area be reduced, but the yields will also likely be significantly lower.

Crop sensors improve nitrogen application

COLUMBIA, Mo. – Sensor-guided nitrogen application can save corn producers money and increase yields, says Peter Scharf, University of Missouri Extension soil scientist.Scharf showed how crop sensors diagnose variable nitrogen needs at a recent farmer technology field day at MU’s Bradford Research Center. In the last decade, on-farm demonstrations have been carried out in more than 100 cornfields and a dozen cotton fields in Missouri.
