We’ve had Liberty Link soybeans in our lineup for several years now, and our customers have had great results with them. There’s virtually no yield drag with the Liberty trait, and Ignite has proven to be equally as effective as glyphosate for weed control. Here’s a link to yield results from one of the Liberty Link test plots we had last season in Eastern Iowa. http://www.lathamseeds.com/YieldResultPDFs/HD_147_SOYBEAN%20PLOT_20... Pretty good results! We’ve also received some testimonials from customers that planted Liberty last year. http://www.lathamseeds.com/liberty-link-testimonials.cfm Hope this helps add some data to your search, and best of luck this growing season!
