Growers faced with challenging weed control problems due to herbicide tolerance are looking for new and improved weed control methods. The recent launch of the Roundup Ready® Xtend Crop System provides growers one of the most effective broadleaf weed control programs. A multi-state project was developed to compare Roundup Ready 2 Xtend® soybean and LibertyLink® trait platforms in a conventional herbicide system to focus solely on germplasm performance.
The objective of this study is to compare soybean yields from Roundup Ready 2 Xtend soybean and LibertyLink soybean products. Field trials were conducted in a weed-free environment, thus eliminating weed control as a confounding factor.
Figure 1. Multi-year average yield of Roundup Ready 2 Xtend® soybeans versus LibertyLink® soybeans. Data from 2016 includes 16 locations and 2017 data includes 14 locations across Michigan, Indiana, Kentucky, and Ohio. Yield means with the same letter are not significant at P = 0.10 (comparison made within testing year).
