The amounts of seed to sow will vary with the character of the soil and climate, with the use that is to be made of the alfalfa, and with the manner in which it is sown. On soils and in climates quite favorable to the growth of alfalfa it is common to sow more seed than in those with less adaptation, and with a view, probably, to check coarseness in the growth of the stems. If sown thinly in such areas, the rank growth which follows would be coarse. This explains why in the Western and mountain States more seed is usually sown than in the Eastern and Northern States. Averaging the whole country, 20 pounds of seed per acre is more frequently mentioned as the proper amount to sow than any other quantity. In the Northern States many growers sow 15 pounds per acre, and judging by the yield obtained, this amount of seed has proved satisfactory. Some growers even mention 10 to 12 pounds as satisfactory. The amounts last named are certainly too small for average conditions. Fifteen to 20 pounds may be fixed upon as the proper amounts to sow on soil in good condition for speedy germination. But many growers claim satisfactory results from sowing larger amounts of seed than those named. Under semi-arid conditions, where irrigation cannot be given, a moderate amount of seed will be more satisfactory than very thick seeding, as when sown too thickly the plants would suffer more from want of moisture than if sown more thinly. The aim should be to obtain a stand that will cover the ground evenly and as thickly as will admit of the vigorous growing of the plants. Because of the relatively long duration of the period of the growth of alfalfa fields, it is specially important that good stands shall be obtained at the first, and for the further reason that the plants will then be better able to contend with intruding weeds, the great bane of alfalfa meadows. When alfalfa is grown mainly for seed, it should be more thinly sown than when it is grown for hay or soiling food. It has been noticed that when the plants stand thickly beyond a certain degree, they do not seed well. Twelve to 16 pounds have been mentioned as quite enough to sow for such production in the mountain States. Where both objects are important, medium thick sowing would be the most suitable.
