Corn Growth and Development: What We Have Learned About Corn Development From Studying Ear Issues

January 23, 2019
In an effort to better understand the causal agents of ear formation issues first seen in corn in 2016-2017, researchers laid out an experiment in 2018 to typify types of ear formation damage as well as possible factors contributing to damage.

Corn, Soybean Planting Considerations for this Week’s Cold Snap

April 24, 2017
With nighttime lows predicted to drop several nights this week, growers are advised to cautiously assess the potential for germination problems due to imbibitional chilling before planting. Agronomists advise checking soil temperatures in each field the day of planting as well as forecast temperatures for 24 hours (soybeans) or 48 hours (corn) after planting.
