To make corn grain production in the Southeastern U.S. more sustainable, producers need to become more efficient by increasing yields and/or decreasing input costs. The use of legume cover crops offers the potential for more sustainable corn grain production by reducing and/or eliminating nitrogen fertilizer, improving soil health, and increasing corn yields.
There is a lot of interest in the value of cover crops to suppress weeds. During the project, we will make a visual assessment of all treatments to determine if the cover crop species are suppressing weed seed germination.
Project objectives from proposal:
To evaluate the effectiveness of the cover crops in suppressing weeds, we will make a visual evaluation of the weeds present in each treatment four weeks after planting and/or prior to any post-emergence herbicide application utilized by the cooperating farmer. The number of weeds and species of each will be determined in a random four foot square block in each treatment.
