  2. StandFastTM Alfalfas Breaking the Yield Barrier Key Features High yielding varieties that carry the Standfast™Alfalfa Technology Traits for improved standability through bloom stage and faster recovery after harvest. Patent Pending

  3. StandFastTM Alfalfas Genetic Background: A synthetic variety developed from crossing European germplasm screened for US adaptability onto elite US fall dormant plants selected for superior yield, forage quality, and persistence. Patent Pending StandFastTM alfalfas are the product of conventional breeding…not GMO’s!

  4. New Alfalfas with the StandFastTM Technology Traits A unique family of tall, fast growing alfalfas with improved standability! Patent Pending

  5. Lodged alfalfa = harvest losses On average, total alfalfa yield for the season decreases 0.5 tons DM/acre for each 1-inch of stem left in the field during the 3 summer cuts (Univ. WI) Patent Pending

  6. Improved Standability! Conventional alfalfas StandFast™ Alfalfas You can see the remarkable differences between conventional varieties and alfalfas with StandFast™traits. Patent Pending

  7. Seed buyers now will be able to evaluate their alfalfa seed for standability! Mercedes = Check Variety with Moderate Standability Europe = Check Variety with High Standability Patent Pending

  18. StandFast Alfalfas • Management Keys • Best adapted to four and five cut harvest system across the traditional fall dormancy 3, 4 and 5 production zones. • The fast recovery trait will help maximize total yield of high quality forage each cropping season. • The fast recovery trait does not express itself fully until the third crop of the seeding year if spring direct seeded. • The improved standability trait will provide in field protection against yield loss starting the seeding year. • Will reach the late bud or early flower stage 3-5 days ahead of current varieties with the same dormancy. • No observed soil type or management limitations. Patent Pending
