  3. Isolation Requirements for Identity Preserved (IP) Non-GMO Corn Production

    https://agcrops.osu.edu/node/4427

    Managing pollen drift is an important consideration in the production of specialty corns and non-GMO (non-transgenic) corn as IP grain crops. Corn is a cross-pollinating crop in which most pollination results from pollen dispersed by wind and gravity. Alt ...

  4. Specialty Corns

    https://agcrops.osu.edu/node/4426

    The type of corn most widely planted in Ohio and across the U.S. is yellow dent. High grain and silage yield potential, high feed value, and availability of adapted superior hybrids account for the widespread use of yellow dents. Yellow dents have the hig ...

  5. Making Replant Decisions

    https://agcrops.osu.edu/node/4422

    Although it is not unusual that 5 to 10 percent of planted seeds fail to establish healthy plants, additional stand losses resulting from insects, frost, hail, flooding or poor seedbed conditions may call for a decision on whether or not to replant a fiel ...

  6. Row Width

    https://agcrops.osu.edu/node/4420

    Since the early 1970s, average row spacing in Ohio decreased from about 35 inches to about 30 inches in 2015. This reduction in row spacing coincided with an increase in average plant population from approximately 18,000 plants per acre to nearly 30,000 p ...

  7. Disease Resistance and Tolerance

    https://agcrops.osu.edu/node/4416

    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 ...

  8. Stalk Quality and Lodging

    https://agcrops.osu.edu/node/4415

    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. ...

  9. 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 ...

  10. 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 ...
