Roundup Ready

Roundup Ready® offers a significant establishment advantage for both yield potential and quality, as a result of improved weed control and crop safety. These varieties offer high levels of pure alfalfa and haylage through low acid detergent fiber (ADF), low natural detergent fiber (NDF) and high relative feed value (RFV).
