Isolation Requirements for Identity Preserved (IP) Non-GMO Corn Production
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 ...
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 ...
Harvest date should be determined by crop maturity, not by the calendar. Plan to harvest fields with potential lodging or harvest loss problems (such as stalk rot or deer damage) first. All field shelled corn with more than 15 percent moisture must be dri ...
Corn Pest Management
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 ...
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
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
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 ...
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 ...
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 ...
