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.

Among other claims for Turkestan alfalfa by the government officials in charge of its introduction and exploitation have been that “its seed will germinate much quicker and the plants start into growth earlier under the same conditions than common alfalfa. The plants are more leafy, grow more rapidly, and have a stronger, more vigorous root system. Another advantage which the Turkestan variety has is that the stems are more slender and less woody, the plants making a more nutritious hay of finer quality. That it will withstand drought under the same conditions better than ordinary alfalfa seems certain from the reports of the experimenters. In the West and Northwest, at least, it seems to be more productive, both with and without irrigation.”
At the North Dakota station Turkestan alfalfa sown in 1901 yielded in the three years following (1902-3-4) at the average rate of slightly more than two tons per acre annually.
Acclimation of alfalfa is a slow process, and numerous close observers think there are too many radical differences in climate and possibly of soil between Turkestan and New Mexico, or North Dakota, to admit of this variety’s becoming a preeminently valuable acquisition to America. It is thought more reasonable to let the American-grown alfalfa gradually accustom itself, as it will, to any particular region, sowing seed from nearly the same latitude and grown under as nearly as possible the conditions it will encounter in its new environment.
In 1903 the Department of Agriculture began experimenting on a small scale at stations in Arizona, California and the warm regions with alfalfa seed procured by Mr. D. G. Fairchild, from Arabia. The officials in charge observe that the plants from this seed appear to make a much quicker growth after cutting, and as a result of this one more crop in a season than is obtained from other alfalfa may be possible. It differs from other strains in having larger leaflets and in being much more hairy. “It is thought very probable that by careful selection hardiness can be bred into Arabian alfalfa so that it will grow much farther north than it does at present.”
