7. Seed either with the drill or by broadcasting. Conditions must be right for either to succeed.
8. Fall seeding and spring seeding are both followed in Oklahoma with good success. If the conditions are not right at seeding time, or turn out unfavorable after seeding, or while the plants are small, either may fail.
9. As a rule fall seeding is preferable in Oklahoma, particularly on the less adapted soils.
10. Take due care in harvesting the hay that half its value is not lost at that time.
11. Don’t give up trying to raise the crop because you fail in your first attempt or even if the failure continues to the second and third attempts. Successful alfalfa raisers have stated that in instances they have failed as many as five times in getting certain fields started to alfalfa, and after they did get the field seeded, the returns from it would justify reseeding ten times if necessary.

George W. Dunn, Jackson county.—For eight years I have grown 60 acres of alfalfa on bottom land with granite loam soil, gravelly and sandy. The plant does not grow well unless the soil is deep and well drained, and will not grow where there is a clay subsoil or stagnant water. Well water is reached at a depth of 10 to 12 feet, and the soil, unless cultivated or irrigated, becomes dry and hard in the summer. As soon as the heavy frosts in the spring are over, seed may be put in, after thorough, deep plowing and pulverizing. I always sow broadcast, 20 to 25 pounds to the acre, then harrow in and clod-mash or roll. Water for irrigation is obtained from streams, and it should be applied as quickly as possible, the best way being to flood the whole field for a few days, and then take all the water off, as standing water will kill the plant quicker than anything else. The quantity of water needed the first and later years does not seem to differ materially. As soon as the young alfalfa is high enough, it should be mowed. This kills the weeds, and gives better chance for growth. Then I cut for hay, but it does not pay much the first year. If land is well drained, the plant lives through the winter easily, and by the second or third year is at its best. In ground adapted to its growth, it is almost everlasting, unless killed by gophers or hogs. After the first season, there are three or four cuttings, averaging each from one to three tons to the acre. For hay, I cut as soon as it begins to bloom freely, ordinarily raking the next day, and cocking the third, in this dry atmosphere. The stack does not shed water well, and the best plan is to put in a good barn. The hay bales well, and the size of bale is simply a matter of opinion or convenience, there being no difference in the keeping quality. The second crop is the one for seed, as the first always contains more or less foul stuff, and the third will not mature seed. I dispose of hay at from $4 to $10 a ton—the same price as other hay in the same market—and it is in great demand for milch cows. The seed costs me from 10 to 16 cents a pound. The straw makes good feed, but of course is not so good as the hay. For feeding farm animals, alfalfa is superior to clover or timothy. We produce as fine beef here, by feeding alfalfa alone, as can be done in Kansas or elsewhere by feeding ordinary hay and corn. The pasturage is profitable and satisfactory for horses and sheep, and for hogs it is unsurpassed—they will grow and fatten on it without other food. Cattle on the pasture sometimes bloat, but not when they are used to it, or when it is dry. I keep about 150 head, and in eight years have lost but two. The roots will grow to, but not into, water, and thrive in deep gravelly or sandy soil. The plant sends down a large, straight taproot, which, as it approaches water, branches and spreads out into numerous small rootlets.

Prof. George C. Watson, Pennsylvania experiment station.—The experiment station has received many letters requesting information pertaining to the growth and cultivation of alfalfa. From these communications it has been learned that many farmers have attempted to grow alfalfa on land that is not at all well suited for this purpose, and consequently, many failures have resulted. The first attempts to grow alfalfa were made wholly by spring seeding, which, in most instances, has proved quite unsatisfactory. As alfalfa starts slowly and exists as a small plant for a considerable length of time, the weeds have an abundant opportunity to germinate and outgrow the more delicate alfalfa plants. Whatever conditions favor the growth of weeds, particularly in the early part of the growing season, materially increase the risk of failure with alfalfa. Largely on account of the weeds and grass, late in summer or fall seeding has been most satisfactory. While a drouth at this time may seriously interfere with germination, yet the injury from insufficient moisture is not likely to be so great as that from a rank growth of weeds earlier in the season. Land that has been cultivated for a few weeks during the summer may be sown to alfalfa in August or September with comparatively little danger from annual weeds, which are so troublesome in spring seeding. Land that is infested with noxious perennial weeds and grass would not, of course, be in suitable condition for seeding after a few weeks of cultivation, no matter how thorough it may be. The most tenacious grasses and weeds, like Canada thistles and quack grass, should be given at least a few months of thorough cultivation before seeding. Experiments indicate that alfalfa will not survive continued alternate freezing and thawing if the soil contains very much moisture. Land that is at all inclined to “heave” is not suited for the growth of this crop. The soil of the station farm, upon which most of these experiments have been made, is a porous limestone clay underlaid with limestone rocks which afford abundant drainage through the fissures. Notwithstanding the fact that the soil is naturally well drained, in some places it seems to hold too much water to afford a most congenial home for alfalfa. This crop will endure severe freezing, provided the soil is sufficiently dry so that it has no tendency to “heave.” Land upon which clover will “heave” undoubtedly contains too much moisture for alfalfa. It seems to be able to endure the rigors of winter better than clover, provided the moisture conditions are favorable.
