Brief Project Summary:
Soybean farmers in South Carolina have historically taken advantage of double cropping soybeans behind small grains. Double cropping works well in this region. Over the last several years, when commodity prices have been considered high, some farmers have double cropped soybeans behind corn, rather than leaving the field fallow. This scenario associates quite a bit of risk, but a considerable number of acres are planted annually in this system. This project evaluates this planting scenario from a whole system approach, including agronomic, pest, disease, fertility, and economic parameters associated with planting soybean behind corn in South Carolina, in order to provide farmers with the best management practices for this scenario.

Information And Results
Project Summary

Soybean farmers in South Carolina have historically taken advantage of double cropping soybean behind small grain, in addition to planting full-season soybean. In order for farmers to take advantage of the maximum profit generated per acre per year, double cropping is a desirable planting scenario, and it works well in our region. Over the last several years, when commodity prices have been considered high, some farmers in SC have taken advantage of double cropping soybean behind corn rather than leaving the field fallow. While this scenario associates quite a bit of risk with it, a considerable number of acres are planted annually in SC with this scenario. In this project, we evaluated this planting scenario from a whole system approach, including agronomic, pest, disease, fertility, and economic parameters associated with planting soybean behind corn in SC, in order to provide farmers with the best management practices for this scenario.

Project Objectives

In this project, we evaluated this planting scenario from a whole system approach, including agronomic, pest, disease, fertility, and economic parameters associated with planting soybean behind corn in SC, in order to provide farmers with the best management practices for this scenario.

Project Deliverables

Four separate trials were conducted to help answer research questions associated with this production practice in the 2022 crop year.

Benefit To Soybean Farmers

The next steps of this project will be to implement these trials again in 2023 to further evaluate this production system to a point where economic analysis can be conducted and best management practices can be established for farmers in SC that wish to utilize this system.

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.
