Technical Abstract: Three soybean cultivars, Derry, Donegal, and Tyrone, bred specifically for use as forage, were released by the U.S. Department of Agriculture in 1997 and are now undergoing seed increase by the seed industry. Seed in limited quantities should be available to farmers for spring planting in 2000. These cultivars were derived from hybridization of a modern multiple pest resistant grain-type cultivars with a traditional hay type cultivar followed by selection for vigorous growth and lodging resistance at Beltsville, MD, State College, PA and Orange, VA. The forage cultivars are characterized by the capacity to grow to 6 feet or more in height. Forage yields as high as 6.4 tons per acre, with 14.5% crude protein and 47 % neutral detergent fiber, have been reported by Cornell University researchers at Chazy, NY in the Champlain valley. Dry matter forage yields in tons per acre obtained at other locations were: Canton, New York, 4.1, Ames, Iowa, 5.2, Rock Springs, Pennsylvania, 4.9, Orange, Virginia, 5.4, Winfield, Alabama, 5.1, and Waseca, Minnesota, 5.5.
