New Alfalfas with the StandFastTM Technology Traits

Patent PendingOn 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)

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.
