Brief Project Summary:

This research seeks to determine a dual threshold based on heat and moisture deficit-related stresses to use to maximize irrigated soybean yield while simultaneously ensuring the greatest water use efficiency and economic return. It develops irrigation scheduling thresholds that ensure proper furrow irrigation to minimize both number of irrigations and amount of irrigation water applied to soybeans.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Project Deliverables

Irrigation scheduling thresholds will be developed that will ensure proper furrow irrigation in
order to minimize both number of irrigations and amount of irrigation water applied to
soybeans.

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.
