Brief Project Summary:

Understanding soybean growth stages is fundamental for all aspects of soybean production. Determining the correct growth stage is essential for timing application of post-applied products, estimating yield potential or yield loss due to crop injury, estimating maturity dates and irrigation scheduling. However, several soybean growth staging systems published in the last 45 years present contradicting and vague descriptions. This project aims to simplify the current growth stage indicators, use the revised stages to better describe soybean seed-fill duration, revise the definition of physiological maturity and harvest maturity, develop a new way to designate maturity groups that reflects the duration of the growing season and define and assign the role of determinacy (e.g. determinate, indeterminate, and semi-determinate).

Information And Results
Project Deliverables

Our goal is also to identify a system that decreases the current variability in the suggested number of days spent in a particular growth stage. Once a potential new staging system is identified, participation and input from other soybean researchers from across the country will be sought to further validate and refine the system.

Final Project Results

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.
