Abstract

Corn plant populations have increased at approximately 400 plants/acre per year over the last two decades. Seeding rates are now commonly 32,000 to 38,000 seeds/acre. Additionally, grain yields are increasing at approximately 1.8 bushels/acre per year since 1996. Because corn plant populations and grain yields are increasing, there has been a renewed interest in looking at corn row spacing and seeding rate.
