Brief Project Summary:

In Oklahoma, a large fraction of the total soybean acres are dedicated to double-crop production systems, where soybean is grown following wheat harvest. This system can be profitable due to two crops being harvested annually, and in many regions, the double-crop system can produce similar yields as a full-season system. But challenges arise that may limit productivity including a shortened season. Documentation has shown that harvesting wheat earlier and planting soybeans sooner can increase yields by up to 9%. The goal of this project is to identify the yield gap associated with double-crop production systems and management practices that can be utilized to optimize productivity and profitability of the double-crop 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.
