Abstract
The foregoing report was reprinted from Alaska’s Agriculture and Forestry, Alaska Rural Development Council Publication No. 3, and the pagination has been changed. Alaska’s Agriculture and Forestry was published in December 1983 by Cooperative Extension Service, University of Alaska and U.S. Department of Agriculture Cooperating, Fairbanks, Alaska. Some of the information in this report represents contributions from research programs of other present and past Alaska Agricultural Experiment Station staff scientists, as indicated by text citations of numbered title s of publications in the reference list above. Foremost among these investigators are R. L. Taylor, W. W. Mitchell, A. L. Brundage, J. D. McKendrick, H. J. Hodgson, and A. C.Wilton.Forage crops can be defined as the aboveground growth (stems, leaves, and sometimes seed heads and immature seeds) of plants that are gathered and fed to
herbivorous, domestic animals. Similar plant growth that is grazed directly by livestock in rotational or permanent pastures, but on a less extensive basis than rangelands, is also considered in this discussion. For the most part, forage crops are herbaceous (nonwoody) members of two large plant families—grasses and legumes. The grass family world-wide numbers about 5,000 species, but only about three dozen of these
are important as forages. The legume family includes more than 12,000 species world-wide, fewer than 20 of which are considered to be important forage crops
