G86-796 Growing Degree Day Requirements and Freeze Risk as a Guide to Selecting and Planting Corn Hybrids

This NebGuide discusses the growing degree day requirements for Nebraska\u27s four corn-growing regions, and how using these requirements can aid in planting date decisions. Variations between locations, between seasons at a particular location, between planting times at a particular location and season, and between the requirements of different hybrids result in differences in the number of days it takes for corn to mature. These variations in days are all closely related to differences in temperatures when the corn is being grown
