Volunteer Glyphosate-Resistant Corn And Soybean Competition And Control, Jill Alms
Electronic Theses and Dissertations
The continuous use of glyphosate-resistant crops has resulted in volunteer crops with the same herbicide resistance as the cash crop and an increasing weed problem. Volunteer corn reduces soybean yields however; little research has examined corn yield loss due to volunteer corn or volunteer soybean competition. These studies investigated yield loss and control of volunteer soybean in corn, and volunteer corn in soybean and corn. Using several densities of competitive plants, the yield loss was fit to a hyperbolic equation that indicated incremental yield loss (I value) to be 29.9 for volunteer corn in soybeans, 5.6 for volunteer corn in …
