The name “Alfalfa” is from an Arabic word meaning “the best fodder,” which honor it can certainly still claim. Many writers have assumed that the name “Lucerne” which it bears in France and England, was from the name of the Swiss canton, Lucerne. This is a mistake as it was not known there until long after it was cultivated in France and England. The name is probably from the Spanish word “Userdas” which the French changed to “La-cuzerdo” and later to “Luzerne,” still later to “Lizerne” and then to “Lucerne.”
Among other names by which alfalfa is known are the following: Lucerne; French Lucerne; French Clover, in part; Mexican Clover, in part; Lucerne Clover; Lucerne Medicago; Alfalfa Clover; Chilian Clover; Brazilian Clover; Syrian Clover; Sainfoin, erroneously; Spanish Trefoil; Purple Medick; Manured Medick; Cultivated Medicago; Medick. Persian, Isfist; Greek, Medicai; Latin, Medica, Herba Medica; Italian, Herba Spagna; Spanish, Melga or Meilga, also (from the Arabic), Alfalfa, Alfasafat; French, La Lucerne; German, Lucerne, Common Fodder, Snail Clover, Blue Snail Clover, Branching Clover, Stem Clover, Monthly Clover, Horned Clover, in part, Perennial Clover, Blue Perennial Clover, Burgundy Clover, Welsh Clover, Sicilian Clover.
Alfalfa belongs to the botanical family Leguminosae, or the legumes, of which there are thousands of species, and is thus related to all clovers, peas, vetches and beans. Its botanical name is Medicago sativa. There are some fifty species of the genus Medicago that are known, but alfalfa and one or two others are all that are of practical value as fodders. It is a true perennial plant, smooth, upright, branching, ordinarily growing from one to four feet high, yet in some instances much higher, owing to conditions of soil, climate and cultivation. Its leaves are three parted, each leaflet being broadest about the middle, rounded in outline and slightly toothed toward the apex. The purple pea-like flowers instead of being in a head, as in red clover, are in long, loose clusters or racemes. These are scattered along the plant’s stems and branches, instead of being especially borne, as in red clover, on the extremities of the branches. The matured seed-pods are spirally twisted through two or three complete curves, and each pod contains several seeds. The seeds are kidney-shaped, and average about one-twelfth of an inch long by half as thick. They are about one-half larger than seeds of red clover, and in color are at their best an olive green or a bright egg-yellow, instead of a reddish or mustard yellow, or faded brown. The ends of the seeds are slightly compressed where they are crowded together in the pod.
Alfalfa is very long-lived; fields in Mexico, it is claimed, have been continuously productive without replanting for over two hundred years, and others in France are known to have flourished for more than a century. Its usual life in the United States is probably from ten to twenty-five years, although there is a field in New York that has been mown successively for over sixty years. It is not unlikely that under its normal conditions and with normal care it would well-nigh be, as it is called, everlasting.
ITS WONDERFUL ROOT SYSTEM
In its root growth it is probably the greatest wonder among plants. While it usually grows no higher than four or five feet (although it has been known to reach more than ten feet; an unirrigated stalk is on exhibition at the office of the Kansas Board of Agriculture, measuring nearly seven feet) and its normal height is about three feet, its roots go down ten, twenty, or more feet, and one case in Nevada is reported by Charles W. Irish, chief of Irrigation Inquiry United States Department of Agriculture, where the roots were found penetrating through crevices in the roof of a tunnel one hundred and twenty-nine feet below the surface of an alfalfa field. Prof. W. P. Headden of Colorado found roots nine feet long from alfalfa only nine months old, and another reports roots seventeen inches long of but four weeks’ growth, the plants being but six inches high. It usually has a slender taproot, with many branches tending downward, yet with considerable lateral growth. As the taproot is piercing the earth it is also sending out new fibrous roots, while the upper ones, decaying, are leaving humus and providing innumerable openings for air, the rains, and fertilizing elements from the surface soil. The mechanical effect of this root-growth and decay in the soil constitutes one of the greatest virtues of the plant, and by its roots alfalfa becomes, self-acting, by far the most efficient, deep reaching subsoiler and renovator known to agriculture.
VARIETIES AND PECULIARITIES
There are several other varieties of alfalfa besides Medicago sativa, the most common being the Intermediate Lucerne or Medicago media, the Yellow Lucerne or Medicago foliata and Turkestan alfalfa or Medicago sativa Turkestanica. None of these have such unqualified value as the ordinary alfalfa; in fact the first two are properly regarded as weeds when found with Medicago sativa. In 1898 when there had been reported many failures in the alfalfa districts of the extreme North and the extreme Southwest, the United States Department of Agriculture sent Prof. N. E. Hansen of South Dakota to Russia, especially the cold, arid and semi-arid portions of northern Turkestan, to discover if possible a more hardy strain of alfalfa than that grown in America. He brought back from there several hundred bushels of seed which was distributed to government stations and individual experimenters in forty-seven states and territories. The reports of its behavior varied greatly, some growers being enthusiastically in its favor, while most reported results below or not above the average from other sorts, and some practically a failure. It would appear from the consensus of opinion at this time that the Turkestan alfalfa has not demonstrated in America any such superiority as to justify its general adoption, even in the dry and warm regions of the Southwest, in our colder states, or in Canada.
