Abstract

Recommendations for soybean seeding rates have been targeted between 125,000 and 140,000 seeds/acre with the objective of targeting a final plant population of at least 100,000 plants/acre. It is understood a 15-in. row spacing has approximately 4.5 bushels/acre higher yields than 30-in. row spacing. Even though this advantage has been identified, the shift to 15-in. rows has not occurred. In recent years, 20-in. row spacing planters have become available. Therefore, this trial was designed to begin to look at seeding rate advantages in 20-in. rows compared with 15-in. and 30-in. row spacing.
