Third Generation Hybrid Alfalfa

Using patented hybrid technology, HybriForce-3400 brings the same performance level producers have come to expect from hybrids in other crops such as corn and canola. HybriForce-3400 is the third generation of HybriForce alfalfa hybrids that deliver unsurpassed forage yield potential. HybriForce-3400 has shown a 5% yield advantage over competitors in extensive research trials (data set of 746 cuts).

HybriForce-3400 delivers exceptional seedling vigor and hybrid performance rewarding growers for many harvests after establishment. Its exceptional regrowth, plant vigor and fine stems allow for more aggressive cutting regimes to yield more and better quality forage. Hybrids by design deliver more yield in the field over commercially produced synthetic varieties.

Yield Protection for Alfalfa Begins with Seed Production

MsSunstra hybrid alfalfa technology protects the forage yield potential in the commercial seed you purchase. How is this accomplished? It is accomplished by controlling pollination with the patented MsSunstra seed production process. Other alfalfas cannot control pollination to this degree. Non-hybrid alfalfa commercial seed suffers yield loss from inbreeding as a result.

* The increased rate of fibre digestion, extent of digestion, and crude protein data was developed from replicated research and on-farm testing. During the 2015 growing season at West Salem, WI and Woodland, CA, the following commercial dormant, semi-dormant and non-dormant alfalfa varieties were compared head-to-head with Hi-Gest™ alfalfa for rate of digestion, extent of digestion and percent crude protein; America’s Alfalfa Brand Ameristand 427TQ, Croplan Brands LegenDairy XHD and Artesia Sunrise, Fertizona Brand Fertilac, S&W Seeds Brands SW6330, SW7410 and SW10, and WL Brands WL 319HQ and WL 354HQ. Also during the 2015 growing season, 32 on-farm Hi-Gest hay and silage samples were submitted to Rock River Laboratory, Inc. for forage analysis. The results for rate of digestion, extent of digestion and per cent crude protein were averaged and compared to the 60-day and four-year running averages for alfalfa in the Rock River database which included approximately 1,700 alfalfa hay and 3,800 silage 60-day test results and 23,000 hay and 62,000 silage tests results in the four-year average.
