Brief Project Summary:

Winter annual cover crops provide many benefits to Kentucky’s agricultural producers. One particularly important benefit is their contribution towards a program of integrated weed management. While growing, cover crops can suppress both winter annual weeds and early-emerging summer annuals like marestail, common ragweed, and common lambsquarters—all problematic weeds in soybean production. After termination, cover crop residues can continue to suppress weed emergence through physical, chemical, and biological means—particularly affecting these early-emerging weed species. The ability of cover crops to outcompete and suppress weeds has been linked to the amount of ground that they cover....

Information And Results
Project Deliverables

One outcome of this project will be a better understanding of what factors are most important in determining how cover crops can contribute to winter annual weed management, and whether these factors also affect in-season weed management in the subsequent soybean crop. Another outcome of this project will be the thesis of an MS student that we would like to work on this project. Additionally, we anticipate that these findings will be disseminated in the peer-reviewed literature and also in blog posts and extension bulletins about the use of cover crops to manage weeds.

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.
