birdsfoot trefoil, forage potential, perennial legume
Birdsfoot trefoil (Lotus corniculatus L.) is a perennial legume similar to alfalfa in growth habit. This species generally is adapted to the temperate climate of the northern part of the United States, where it is a hay and pasture crop of major importance. Birdsfoot trefoil is suitable for South Dakota, but it has not been planted in large acreages in the state primarily because of the popularity of alfalfa as a hay and pasture crop. Birdsfoot trefoil, however, has several characteristics that make it superior to alfalfa in certain situations. It deserves consideration as a possible South Dakota forage crop.
