Alfalfa is a herbaceous perennial forage crop in the plant family Medicago. Alfalfa is well adapted to growing conditions in South Dakota if a variety with good winter hardiness has been selected. Several vegetative stems are produced from the crown during each growth cycle, and the plant has a deep, branched taproot system that allows it to produce acceptable forage yields, even under relatively dry conditions.
South Dakota is one of the leading alfalfa growing states in the U.S., annually producing more than six million tons of alfalfa hay for all uses.
