Research Project: Determining the Causes of Declining Test Weight of Soybean and Utilizing Breeding to Increase Test Weight

Location: Soybean and Nitrogen Fixation Research

Project Number: 6070-21220-070-068-A
Project Type: Cooperative Agreement

Start Date: Oct 1, 2024
End Date: Sep 30, 2025

Objective:
Determine the relation of test weight to seed size, seed quality, protein and oil content, sucrose concentration, amino acid content and yield.

Approach:
The Cooperator will utilize the Culler’s Rotation which consists of 14 different fertility treatments. This rotation was established in 1911 and will give accurate information on the impacts of fertility on test weight and seed composition. Seed composition traits and yield will be evaluated under 14 different long term fertility treatments.
