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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
