Results from 97 field scale trials around Indiana since 2008 suggest that maximum yield response to plant populations for 30-inch row corn grown under minimal to moderate stress conditions occurs at about 32,150 PLANTS per acre (ppa), equal to seeding rates of about 33,840 SEEDS per acre (spa).

This summary focuses on our recent research evaluating the yield response of corn to plant population in field scale trials conducted around the state of Indiana.
