Brief Project Summary:

It has been well established that planting soybean early will generally result in the greatest yield potential. However, in recent years the question has become “How early is too early?” In addition, if very early planting dates occur “Should management practices be changed for these very early planting dates?”
The specific objectives of this study are to:
1) Determine when the plant canopy closes and seed yield and quality of early-planted soybean
2) Determine when the plant canopy closes and seed yield and quality of soybean that receive broadcast sulfur and nitrogen after planting, but before seedling emergence
3) Determine which soybean relative maturity groups maximize seed yield...

Project Deliverables

Identification of agronomic management strategies that maximize profitable soybean production when planted early in the season.

Final Project Results

On December 10th, 2021, UKREC sustained a direct hit from an EF4 tornado with 190 MPH wind speeds. All 2021 soybean samples that were collected for quality and pod count data were lost or destroyed along with electronic canopy closure data. Equipment was not available to plant the earliest planting in March. We will not be able to conclude the project in 2022.

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.
