Row Spacing: In a combined analysis across research locations and varieties, narrow
rows provided a 7 bu/A yield advantage over wider row spacing.
• Seeding Rate: In a combined analysis across research locations and varieties, soybean
yield declined at seeding rates below 100,000 seeds/A.
• R1 Fertility: Our results indicate that despite high soybean nutrient demand at R1, soil-applied R1 fertility applications have no impact on soybean yield. This may be attributed
to delayed nutrient availability not synchronizing with peak soybean demand.
• Seed Quality: Seed quality can be an issue with earlier maturing soybean varieties.
Timely harvest is critical to prevent seed quality declines.
