Brief Project Summary:

Double-crop soybean is one way of increasing production and net return. The objective of this project is to evaluate different management treatments and their effect on double-crop soybean planted after wheat harvest and identify the main yield-limiting factors affecting crop productivity from a perspective of environment and management practices compared to full-season soybeans. The project is based on an all-encompassing experiment, comparing low input common practice, treatments that included all yield enhancing inputs (“kitchen sink” including higher fertility, pest control, row spacing, seed density), and treatments that excluded individual inputs from the “kitchen sink” treatment.

Key Benefactors:
farmers, agronomists, extension specialists, ag retailers

Information And Results
Final Project Results

The project has been completed, all field, seed quality, modeling, and review components were accomplished. The report attached as a first document (File 1) presents the summary of the main outcomes regarding field activities and seed quality analysis (fatty acids). The second document attached (File 2) presents the recently published review paper synthesizing several scientific research studies on this topic and providing new insights on the factors affecting potential yield in double cropped soybeans, primarily governed by planting date and previous wheat yield. More publications and Extension documents are currently in preparation as a part of finishing the efforts of extending this great information to our soybean farmers.

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.
