Date of Planting
The recommended time for planting corn in northern Ohio is April 15 to May 10 and in southern Ohio, April 10 to May 10. Approximately 100 to 150 GDDs (heat units) are required for corn to emerge. In central Ohio, this number of GDDs usually accumulates by ...
The protein and oil composition of corn grain is a major factor affecting grain feeding value. Although the grain market does not include this factor in price determination, growers who feed livestock may use this information to reduce feed costs and opti ...
Growing Degree Day (GDD) Maturity Rating System
The GDD maturity rating system is based on heat units. It is more accurate in determining hybrid maturity than the days to maturity system because growth of the corn plant is directly related to the accumulation of heat over time rather than the number of ...
How Climate Affects Corn Production
Temperature Corn can survive brief exposures to adverse temperatures―low-end adverse temperatures being around 32 degrees Fahrenheit and high-end ones being around 112 degrees Fahrenheit. Growth decreases once temperatures dip to 41 degrees Fahrenheit or ...
