Prof. William P. Brooks, Director Hatch experiment station.—Our experiments with alfalfa have been continued both upon our own grounds and those of a few selected farms in different parts of the state. We are bringing to bear upon these experiments information in regard to successful methods from every possible source. We find in all cases a distinct benefit from a heavy initial application of lime. We have used from 2,000 to 3,000 pounds per acre. We are enriching soils already naturally good by heavy applications both of manures and fertilizers, using materials which experience has proved best. We are also giving the soil a most thorough preparatory tillage. It has usually been fall-plowed, and in addition it is plowed in the spring, and repeatedly harrowed to destroy weeds which start in the early part of the season. We have tried inoculating the soil, both with earth obtained from a field in New York, where alfalfa is successfully grown and with the cultures sent out by the department of agriculture and prepared by private firms. We have not attained such degree of success as justifies us in recommending the crop. We have occasionally got a fair stand of alfalfa, but in all cases the winters prove more or less injurious. In the course of a few years the alfalfa is mostly crowded out by grasses and clovers. The alfalfa almost every year suffers from leaf spot, which tends to cut down the yield. We have found a very distinct benefit from the inoculation with earth from the New York alfalfa field. We have not found an equally distinct benefit to follow inoculation with any of the cultures; and, although we are not as yet ready to make a final report, it should be here remarked that the most careful experiments on the use of these cultures in sterilized soils, under conditions calculated to give accurate results, indicate that they have little, if any, value. In our various experiments alfalfa has been tried on a wide variety of soils. We have had a quarter of an acre field upon a coarse-textured soil upon a farm in this neighborhood where there is never any standing water within 50 to 60 feet of the surface. Even on this soil the alfalfa, although it did fairly well for a year, has been injured by successive winters, until it is at the present time almost ruined. In this connection I call attention further to the fact that D. S. Bliss of the department of agriculture, who has been making special efforts to promote the introduction of alfalfa into New England, and who has traveled extensively for the purpose of studying the results obtained, now speaks very discouragingly as to the outlook in general. In conclusion, while we are not inclined to discourage experiments with alfalfa, we do wish most emphatically to caution against engaging in these experiments upon an extended scale, for we feel that disappointment is almost inevitable.
MICHIGAN
Prof. C. D. Smith, Director Michigan experiment station.—Alfalfa has had and is having a checkered career. Under favorable conditions it makes a good stand. Some fields have produced crops for many years, the ground being occasionally fertilized by manurial salts. The difficulties that environ the crop are: (1) The severe winters, which sometimes kill off whole fields, leaving scarcely a root alive; this has happened to fields two, three, or four years old. (2) The Blue grass crowds it out badly; (3) the ignorance of the farmers in regard to the requirements of the crop and the consequent imperfect preparation of the soil in the matter of tillage or fertilization, has made it difficult to introduce it in a broad way. Notwithstanding these difficulties and the farther consideration that alfalfa does not easily lend itself to a short rotation, the crop is advancing in the state by leaps and bounds. Hundreds of farmers are experimenting with it and are learning how to prepare the ground, sow it and care for the crop afterwards. Statistics are not at hand to show how many acres of alfalfa there are in the state, nor can definite figures be given as to the growth of interest in the crop and its actual acreage. When proper strains have been developed, it seems fair to presume that alfalfa will be one of the staple crops in Michigan. On the station grounds at the agricultural college fields of alfalfa have been continuously maintained from 1897 to 1904. There are fields here sown in 1903 bearing their three crops each year, yielding from 5 to 7 tons of dry hay annually per acre. There has been some difficulty in getting pure and vigorous seed.
MINNESOTA
Prof. W. M. Liggett, Director Minnesota experiment station.—Our experience with alfalfa has extended over 12 or 15 years. In the early days of this station, it was not very successfully grown. During the past eight or ten years, however, the changes in soil due to manures and cultivation and the discovery of several varieties of alfalfa which appear to be hardy, have made it possible to grow it successfully in nearly every part of the state. For the past five years we have cut three crops of alfalfa hay, yielding from 4 to 51⁄2 tons per acre each year. With the land properly prepared and some attention given to seeding at the right time, there is no difficulty in growing it on the state farm. Occasionally it will winterkill. We were unfortunate enough to have a heavy, driving rain during March of the present year which froze as it fell and smothered the alfalfa crop. We are not discouraged, however, as the clover crop in southeastern Minnesota was killed at the same time and from the same cause. We regard alfalfa just as sure as Red clover. It is sometimes a little difficult to get a stand under careless methods of farming. With the land nicely prepared and with a good supply of humus in such condition that the plant food is readily available, strong, vigorous growth and a good stand can be secured during any normal year. We have alfalfa growing at the northwest sub-station at Crookston, and in several localities in the northwestern part of the state, where even clover is not supposed to grow. The outlook at the present time for this crop is very bright. Dairymen, swine raisers and sheep men unite in praising its merits as stock food.
MISSOURI
Prof. M. F. Miller, Agronomist, Missouri experiment station.—Alfalfa is being grown with success on various types of soil, although many soils are not well adapted to its growth. A knowledge of the peculiarities of the plant will ultimately make it possible to extend Its culture to most soil types of the state. Liberal manuring is the key to successful culture on upland soils. The manure may be applied before plowing and also as frequent top-dressings. The value of the crop as a feed and its high yield, where favorable conditions are supplied, make it a particularly desirable one to grow, at least in small areas, on farms where mixed fanning or dairy farming is practiced. While alfalfa makes a most nutritious pasture crop, it does not lend itself well to pasturing unless certain precautions are taken. Where it is grown for hay, difficulty is often experienced in harvesting the first, and sometimes other cuttings, on account of wet weather. The silo may be used in such cases. The stiff subsoils of the state are responsible for most failures reported, because it requires some knowledge of the methods of handling the crop to make it succeed under such conditions. Alfalfa is not adapted to our soils, liming, manuring or drainage being necessary to prepare such for the crop. If sown on upland soils that have never grown alfalfa or Sweet clover, it is benefited by inoculation. On bottom lands or lands that are very fertile, inoculation has little or no effect. The surest and often the simplest means of inoculation is by means of inoculated soil. The cultures prepared for seed inoculation have in many cases given excellent results, but they are still in the experimental stage and some skill is required to handle them properly. The best preparation of the seedbed is that which allows of an early plowing and the use of a harrow every time a crust forms or weeds start before time to sow the seed. The seedbed should be much like that for wheat—loose above but firm below. The best time to sow in this state is between the middle of August and the middle of September, the last week in August usually giving best results. The amount of seed to sow is between 15 and 20 pounds, depending upon the quality and the character of the soil. It is best sown without a nurse crop. It must be clipped frequently the first and sometimes the second season, especially on soils to which it is not well adapted. It should usually be cut when the lower leaves begin to turn yellow.
MONTANA
Alfred Rasicot, Deer Lodge county.—Alfalfa is the most valuable crop that is raised in Idaho or Utah for hay, growing on any kind of land but that which is low and wet, yielding five to seven tons of hay to the acre, and providing excellent feed for all kinds of farm animals. For about 20 years I have grown from 20 to 50 acres on second bottom and upland of heavy clay soil, with gravel below and water at a depth varying from 16 to 100 feet on different localities. We irrigate from streams, flooding the land and turning the water off as soon as the land has been all covered, applying once for the first cutting and twice for each succeeding cutting, whenever the ground is dry. The first year on new land requires fully one-third more water than is needed afterward. Before seeding, the ground should be mellow, then harrowed with the back part of the harrow or brushed, and seeded with 15 to 20 pounds to the acre, between the first and middle of April. The plant will usually run out the weeds, and on that account no special treatment is needed. The first season will produce a small crop of hay, but no good seed. Unless water is allowed to freeze on the land, alfalfa does not winterkill here, and at two or three years of age it is at its best, continuing vigorous for 10, 20 or 30 years without seeding. The first cutting of the season yields about 21⁄2 to 3 tons to the acre, the second about 2 to 21⁄2, and the third 1 to 11⁄2 tons. The hay is cut when the plant has been in bloom 8 or 10 days, allowed to lie for 24 to 36 hours, and treated as Red clover is. The second crop is always the best for seed here. The cost in the stack, on $25 land, irrigation costing 50 to 75 cents an acre, is $2 a ton. To put this into 100-pound bales costs $2.50 a ton. On the ground it sells for $3 to $5 a ton, while the seed brings $3, $4 and $5 a bushel. An ordinary yield of seed is 300 pounds to the acre, and this is threshed with the same machine used for grain, at a cost of about one-fourth of the seed. The straw is worth about one-fourth as much as the hay. We consider alfalfa hay, for cattle, sheep, and hogs, far superior to clover, but for horses timothy is best. It will keep steers and sheep fat all winter, providing they are under shelter, and is excellent for milch cows. The pasture for swine and cattle is far better than clover, and for work horses and sheep it is good, but not the best for horses that are driven fast. Cattle will bloat about as they do on Red clover when turned onto it after rain, dew, or frost. To rid land of a stand of alfalfa is very difficult, requiring four stout horses with a very sharp plow to turn it over, but as a green manure it has about the same effect as Red clover, producing two or three extra crops afterwards.
