Brief Project Summary:

Producers need specific recommendations on when to start and stop irrigating soybeans (while taking into account soil moisture) to optimize yield and maximize profit. Should irrigation begin at first flowering (R1) or at pod initiation (R3)? Would irrigating as early as V3 provide any yield benefit or just increase lodging, insect and disease problems, and cost? Do varieties with different maturities require different irrigation scheduling to optimize yield? Should irrigation be terminated when the seeds are full (R6) or at beginning maturity (R7)?

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.
