Project Summary

Several soybean systems are available for weed management in the United States. This study will compare yields from the Roundup Ready (RR), the Roundup Ready 2 Xtend (Xtend) and the Liberty Link (LL) systems. Where possible, this study will compare genetic yield comparisons across technologies. The study will test up to five varieties from each RR, Xtend and LL soybeans. Herbicide programs that match each technology group will be used post emergence. For the RR and Xtend technologies, the glyphosate-only program will be included as well to allow us to compare genetic yield potential. Weeds will not be allowed to reduce soybean yield. Thus, the yield comparisons will examine the systems and the genetics, only.

Project Objectives

To evaluate relative yield of RR soybean, LL soybean and Xtend soybean in their respective weed management systems.
