TENNESSEE
Prof. H. A. Morgan, Director Tennessee experiment station.—Alfalfa has been known in Tennessee for many years, but not until the general failure of Red clover, due to one or more species of Colletotrichum, and the search for substitutes for Red clover, were any serious efforts made to grow alfalfa in this state. On alluvial land along the Mississippi river in west Tennessee, in what is known as the Central Basin section of middle Tennessee, and on the richer lands of east Tennessee, alfalfa has been grown very successfully, and each year large areas are being sown to this clover. Mr. L. Donaldson, of Lake county, gives the following relative to the preparation of soil, etc., for alfalfa in the alluvial area of west Tennessee: “The land is plowed deep with large moldboard breaking plows in September or about the first of March. It is then harrowed until thoroughly pulverized, and either about October 10 or April 1, two gallons of seed are sown, by machine or by hand. The harrow is used for covering the seed. We have no more trouble with the crop after seeding. The plants germinate and take root rapidly. I have known alfalfa roots to reach a length of two feet from the last of March to June 25. We frequently cut the crop five times per year.” George Campbell Brown of Maury county states that he has sown alfalfa in March using spring barley as nurse crop, and in September with success. Land sown to alfalfa in 1901 yielded four cuttings per year in 1902, 1903, and 1904, averaging from 16 to 18 tons per acre in the three years. Mr. Brown uses soil for inoculating, and believes he has gotten well-defined results from nitro-culture sent out by United States department of agriculture. At the experiment station at Knoxville, alfalfa has been successfully grown for many years. Heavy applications of farmyard manure and the use of 300 pounds of acid phosphate and 25 bushels of lime per acre invariably insures large yields of alfalfa. Crab grass, Panicum sanguinale, in summer and chickweed, Stellaria media, in winter are enemies to alfalfa in this latitude. These pests should be gotten rid of by the use of clean culture crops preparatory to the sowing of alfalfa. With plenty of stable manure, lime, and phosphorous, artificial inoculation seems unnecessary. Any soil of over a few feet deep may be prepared so as to grow profitable crops of alfalfa. This preparation is much more expensive on some soils than others.
