Reports of seed sown, varying from six to sixty pounds to the acre, indicate much ignorance of the nature of the alfalfa plant; or a great recklessness and extravagance. Twenty pounds to the acre, if all seeds germinated, would mean 2,500,000 to 3,000,000 plants, whereas a stand of 500,000 is ample. Most of the experiment stations favor twenty to thirty pounds to the acre, although several experts at these stations insist that fifteen pounds of clean, germinable seed to the acre is as much as should be sowed. Even if these all grew it would give nearly 44 plants to the foot square of land, or four to five times as many as would thrive after two years old. Of course the quantity may depend upon a variety of circumstances, such as the vitality of the seed, condition of the surface soil, condition of the subsoil as to moisture, the method of sowing, weather conditions at the time of sowing or immediately after, also the natural fertility of the soil and the bacterial life present, or at least the conditions for propagating or sustaining bacterial life. With land prepared by sowing a few pounds of seed six months or a year preceding, with a heavy application of stable manure plowed under six months before, perfect soil preparation, normal moisture, and clean seed, testing ninety per cent germinable, there should be no need for more than ten pounds to the acre. Disking that the field should have later will split the crowns and many new stalks will be sent up; so that in a few years a square foot of surface will not accommodate more than six to ten robust, vigorous plants, and having these the ideal stand has pretty nearly been attained. One plant has been known to send out as many as 360 branches from its single main root, resembling in form a spreading bush. A successful farmer in Geary county, Kansas, who has been raising alfalfa for twenty years, seldom sows more than six pounds of seed to the acre and never more than ten. A prominent Ohio farmer usually sows but ten, and never over twelve or fifteen pounds to the acre, although he has always introduced alfalfa bacteria into the soil one or two years before ready to give it a full seeding. Of strictly good seed, well cleaned, twelve pounds would likely be too much rather than too little, other conditions being right. WITH OR WITHOUT A NURSE CROP?
