Abstract

Producers continue to plant corn at higher plant populations each year. Seeding rates have increased about 425 seeds per acre per year since 2001 in Iowa. The ability of today’s hybrids to manage this extra plant-to-plant competition has been a catalyst for higher yields. During this same time, seed costs have risen dramatically. The purpose of this study was to look at different corn plant populations and the effect these populations have on yield and economics.
