Alfalfa
Bred to Perform.
Proven to Persist.
Legacy Seeds breeds alfalfa for the real world—focused on persistence, protection, and productivity. Our portfolio spans fall dormancy (FD) 2–6 to match local environments and harvest goals. For international partners, we offer non-GMO foundation seed with FD 2–5 to support local production and purity needs.
“Legacy alfalfa is as a consistent hay as we’ve ever used. Four–five year stands that continue to bring tonnage and quality. We wouldn’t have used it for 10 years if it weren’t.”
Josh Silverthorn, Silver-Shea Holsteins, Omro, WI
Legacy HD® Alfalfa
These high yielding and persistent varieties are Highly Digestible (HD®) and provide increased milk production and profitability. In Legacy Seeds alfalfa research trials our Legacy Brand HD® alfalfa varieties average producing approximately 110% more milk per acre than top competitor’s varieties.
Legacy StandLife Genetics® Alfalfa
In many areas of the Midwest Aphanomyces Races 2 and 3 are severe root pruning disease that reduces yields and the stand-life of alfalfa fields. Legacy Seeds’ StandLife Genetics® varieties have High Resistance to multiple strains of these diseases as well as high resistance to all of the main alfalfa diseases. These varieties perform exceptionally well in a variety of soil types and conditions.
Roundup Ready® Alfalfa
The Roundup Ready® Alfalfa system provides the opportunity to deliver unsurpassed weed control with superior crop safety, allowing you to grow more, higher-quality alfalfa. With the broadest application timing window plus excellent crop safety, Roundup Ready Alfalfa requires minimal waiting — only 5 days before grazing or harvest. Roundup Ready Alfalfa can deliver a higher percentage of pure alfalfa in hay and haylage than competitors, along with improved quality, and has low ADF (acid detergent fiber), low NDF (neutral detergent fiber) and high RFV (relative feed value).
