SPRING OR FALL SOWING—WHICH?
This has been a much argued question with experimenters. Possibly it will be found to be of minor importance in itself, depending more upon other conditions than the season. From the northern tier of states many reports favor spring sowing, yet from each come letters in favor of fall sowing. Several experiment stations in the South are in favor of spring sowing, yet report satisfactory results from fall seeding. It seems pretty well established, however, that fall sowing is safer in the central latitude states, say including Ohio, Nebraska, Missouri, Kansas, Colorado and Utah, and states within the same parallels.
In other states prevailing opinions favor spring sowing. Nevertheless, when all conditions are understood, fall sowing seems likely to become the established practice throughout the United States. This is in line with the system for the more staple crops and common rotation; it gives opportunity to bring the ground into better condition; the preparation and sowing come at the most convenient season, and one of relatively greater leisure; there is less interruption by unfavorable weather; the soil, responding more readily to surface cultivation, permits the work to be done with less danger of surface water retarding normal root development, and the annual weeds being dead they cannot interfere with the first growth of the alfalfa. Sown in the fall, with time to secure some growth for winter protection, alfalfa will be ready to respond to the first call of spring, and for the mower early in June. Moreover, if it fails from freezing or other cause, little crop-time is lost. The farmer has but to disk and harrow in April or early May, and sow half as much seed as he sowed in the fall, and he will have prospect of a cutting in eighty or ninety days, at an expenditure of but few pounds of seed and a little labor.
