The appropriate planting depth varies with soil and weather conditions. For normal conditions, plant corn 1.5- to 2-inches deep to ensure adequate moisture uptake and seed-soil contact, provide frost protection and allow for adequate root development. Sha ...
Disease Resistance and Tolerance
Hybrids should be selected for resistance or tolerance to stalk rots, foliar diseases and ear rots, particularly those that have occurred locally. Seed dealers should provide information on hybrid reactions to specific diseases in Ohio (Table 4-21). See t ...
Stalk Quality and Lodging
Hybrids with poor stalk quality should be avoided for grain production even if they show outstanding yield potential. Hybrid stalk quality as measured by stalk lodging (stalk breakage below the ear) at harvest has improved greatly over the last 20 years. ...
Yield Potential and Stability
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 ...
Days to Maturity Rating System
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 ...
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 ...
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 ...
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 ...
