  1. Corn Pest Management

    https://agcrops.osu.edu/node/4424

    Weed Control  A number of factors need to be considered when developing weed control programs for corn, including soil type, weeds, weeds present, crop rotation and budget. No single control program effectively handles the various weed problems that arise ...

  2. Fertility Recommendations

    https://agcrops.osu.edu/node/4423

    A good nutrient management program is one of the keys to high yield corn production. Instituting best management techniques to ensure adequate nutrient availability throughout the growing season can pay real dividends at the end of the year and minimize t ...

  3. 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 ...

  4. Plant Populations and Seeding Rates

    https://agcrops.osu.edu/node/4421

    When corn is produced for grain in Ohio, recommended plant populations at harvest (or final stand) can range from 24,000 to 34,000+ plants per acre, depending on the hybrid and production environment. Yield response to plant population is influenced by se ...

  5. 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 ...

  6. Seeding Depth

    https://agcrops.osu.edu/node/4419

    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 ...

  7. Date of Planting

    https://agcrops.osu.edu/node/4418

    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 ...

  8. Grain Quality

    https://agcrops.osu.edu/node/4417

    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 ...

  9. 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 ...

  10. 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. ...
