Brief Project Summary:

This project supports research trials on the early maturity of soybean crops in both North and South Carolina. These results coupled with a second year of research should provide robust information for a summary of production practice impact in earlier maturing soybeans in the Carolinas.

Information And Results
Final Project Results

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.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
