JERUSALEM ARTICHOKES AS COW-FEED. BY CHRISTOPHER SHEARER, TUCKERTON, PA. Butter and milk are not only luxuries, but in many families they are indispensable necessaries of life. In this article my principal purpose is to show how a cow can be kept with the greatest economy of land and labor. I consider these the essential points in the discussion. Where hay is dear and pasture scarce, a man who lives by the labor of his hands, cannot ordinarily afford to purchase the necessary food for a cow; and if he has only an acre or two of land at his disposal, he finds it more profitable to raise other products. Ordinarily it requires the yield of several acres of land to support a cow. But I propose to show that this can be done on less than one acre, by raising the proper crops, and treating the soil to the best advantage. A cow of ordinary size will consume about eleven thousand pounds of hay, or its equivalent, in a year. The equivalent of this amount of hay is—in potatoes, thirty thousand eight hundred pounds, or five hundred and thirteen bushels, and in Indian corn, seven thousand seven hundred pounds, or one hundred and thirty-seven bushels. These quantities cannot be raised on one acre, and if we examine the tables of equivalents of food, we find that most of the grasses, grains, and roots, are objectionable on account of unproductiveness, want of sufficient nutritive qualities, or of the labor that the cultivation of them requires. VALUE OF ARTICHOKES. There is, however, a root, or tuber, an acre of which affords enough nourishment to sustain two cows, with less labor than is employed in raising an acre of potatoes—and that root is the Jerusalem Artichoke (_Helianthus tuberosus_). We can depend upon an average yield of from one thousand to one thousand two hundred bushels of these tubers from an acre of land rich enough to produce fifty bushels of corn. Pound for pound they are equal in nutritive qualities to potatoes. One cow can therefore be subsisted a year on five hundred or six hundred bushels of the tubers, a quantity that can be raised on half an acre of land. But since these roots do not keep over summer, and as the cow will not thrive on them alone, it is necessary to supplement them with dry fodder during winter, and to subsist her on other forage during summer. With the aid of this plant, three-quarters of an acre of land under high cultivation, will nourish a cow during the whole year, and the soil will become rich without any other manure than that derived from the cow. This can be done with little expense, and with no more labor than is involved in ordinary farm culture. It is necessary to begin operations on the farm in most sections of the Middle States, a little earlier than the first of May.
