Abstract

Corn plant populations have increased at approximately 400 plants/acre per year over the last two decades. Seeding rates are now commonly in the 32,000 to 38,000 seeds/acre range with some hybrids being recommended at higher seeding rates. Because corn plant populations and grain yields are increasing, there has been a renewed interest in looking at corn seeding rate and nitrogen rate interactions.
