SW404S

Dormancy 4 Alfalfa

SW404S is a blend of S&W alfalfa germplasm, containing an elite salt tolerant variety along with high yielding, winter hardy conventional alfalfa. Broad adaptability to both saline and non-saline growing conditions. Adapted to Plains and Western US FD4 growing areas.

Key Advantages

• Good establishment, yield and stand longevity in fields where irrigation water and/or soil contains moderate salt concentration
• Highly suitable for fields with saline spots where salt tolerance is helpful, but not needed across the entire field
• Adaptable where winter and spring precipitation drive salts down, but irrigation water applied later in the season has moderate salinity
• Includes a fall dormant salt tolerant variety bred in saline growing conditions and selected for the ability to maintain improved alfalfa production in saline soils
• Best-suited to fields with moderate saline growing conditions, and fields with variable saline conditions
• The blend of high yield plus salt tolerant germplasm can help boost yields during heavy spring growth after winter precipitation drives down soil salt concentration
• The salt tolerant component helps preserve more yield when soils become drier or when saline irrigation water affects salinity levels late in the growing season.
