Alfalfa is a perennial legume used for hay and grazing. Establishment requires a firm seedbed, high levels of P & K, and a pH of 6.0 to 6.5. Alfalfa stands cannot be thickened with interseeding. Alfalfas are rated on the Wisconsin Disease Index (WDI), X out of 30, and by Fall Dormancy (FD), the higher the number the longer the growing season.  Newer varieties may be scored on a 35-point scale with the addition of aphonomyces race 2 testing. 























Optimum 4.2    WDI – 35/35, FD: 4

Green Valley’s leader in alfalfa performance with an outstanding trait package that raises the achievement bar to the next level. Optimum 4.2 boasts a 35/35 on the disease rating index, has the best winter hardiness score available, is resistant to stem nematode, and top all that off with high resistance to Aphanomyces Race 2. Whether it’s for exceptional forage yields, superior forage quality or very fast recovery after cutting, Optimum 4.2 is the choice for commercial hay, beef and dairy producers.


Optimum DP    WDI – 35/35, FD: 4

Optimum DP is the “dual purpose” alfalfa of our lineup.  This sunken crown alfalfa performs great in both hay and pasture scenarios.  The branch root feature of this alfalfa also allows it to be more productive in poorer drained soils.   Add high resistance ratings for multiple aphonomyces races and it is easy to see why this new variety had the credentials to join our Optimum lineup.


Optimum LH    WDI – 35/35, FD: 4

Optimum LH is the optimum choice for an alfalfa that offers high resistance to potato leafhopper.  Optimum LH tolerates a wide range of environmental and soil conditions with characteristics such as high resistance to aphonomyces race 2, excellent persistence, fast recovery after cutting, and high relative feed quality in sprayed or unsprayed conditions.  High yield potential, strong winter hardiness, and an elite agronomic makeup ensure Optimum LH is an excellent choice where stright alfalfa stands are desired. 


Resolute    WDI – 28/30, FD: 4

Our best-selling alfalfa. Resolute is a blend of alfalfas chosen for their ability to produce high quality feed while maintaining stand integrity. Most often used in forage mixtures or short duration stands.
