The genus "Onobrychis" comprises 54 different species of which "O. viciifolia" is of greatest agronomic importance. Two different agricultural types of "O. viciifolia" are known. The single-cut type is characterized by a vegetative regrowth after cutting and its origin is in Europe. A generative regrowth after cutting is typical for the second or the double-cut type. Originated in the Middle East the double-cut type grows larger than the single-cut type. Compared to other forage legumes both types are weak in competition and their regrowth after mowing is considered to be low. Also the yields of common sainfoin are significantly lower than those of alfalfa and clover.
