Birdsfoot trefoil shows considerable promise as a perennial pasture legume for use in southern Iowa. Small plot and field plantings we have made show that it thrives growing with bluegrass. Cattle graze it freely, and when grown with bluegrass the forage production is not only increased but the birdsfoot trefoil, like alfalfa, continues to grow through the summer when bluegrass “takes a nap.”
