how much seed is needed to plant an acre of corn
An acre planted in this way produces about 17,000 plants, according to the North Carolina Cooperative Extension Service. For an acre of a regular sweet corn planted as mentioned above, you will need 9 to 10 pounds of seed per acre. For super-sweet corn patches, you'll only need 5 to 6 pounds of seed per acre.
