  1. Yield Potential and Stability

    https://agcrops.osu.edu/node/4414

    Choose hybrids that have produced consistently high yields across a number of locations and/or years. The Ohio Corn Performance Tests (OCPT) indicate that hybrids of similar maturity vary in yield potential by as much as 40 bushels per acre or more. Choos ...

  2. Growing Degree Day (GDD) Maturity Rating System

    https://agcrops.osu.edu/node/4413

    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 ...

  3. Days to Maturity Rating System

    https://agcrops.osu.edu/node/4412

    The most common maturity rating system is the days to maturity system. This system does not reflect actual calendar time between planting and maturity―a 106-day hybrid, for example, does not actually mature 106 days after planting. A days to maturity rati ...

  4. Maturity

    https://agcrops.osu.edu/node/4411

    Growers should choose hybrids with maturity ranges appropriate for their geographic area or circumstances. Corn for grain should reach physiological maturity or “black layer” (maximum kernel dry weight) one to two weeks before the first killing frost in t ...

  5. Hybrid Selection

    https://agcrops.osu.edu/node/4410

    Selecting a group of hybrids for planting is a key step in designing a successful corn production system. To stay competitive, growers must introduce new hybrids to their acreage on a regular basis. During the past 40 years, the genetics of corn hybrids h ...

  6. How Climate Affects Corn Production

    https://agcrops.osu.edu/node/4407

    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 ...
