Despite the above-average yields in recent years, there has been reports of ear formation issues in corn that ranged from sites in the Texas Panhandle, Colorado, Nebraska, Iowa, and Illinois. Does planting date play a role?
Do delayed planting dates affect plant growth (leaf height, stem diameter, and internode length) and ear formation issues in corn? See what this student researcher learned from trials conducted near Clay Center in summer 2018.
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.
