In the case of the average yield for 1896 with seven tillings when there was produced 343 bushels per acre, the amount of dry matter was 4, pounds, or tons. To mature this amount would require some tons of water. This was secured to the plants by early and deep plowing of the land to establish the earth mulch and to prevent loss of the spring rains, and then by frequent surface tillage the mulch was renewed to lessen the loss of moisture by evaporation. The conservation of moisture by frequent tillage cannot be too strongly enforced. The liberal application of fertilizers, or the presence of large amounts of readily available plant-food. 55.—Cultivator well suited to potato culture during earlier period of growth. will prove of but little value if the moisture supply is deficient. The old notion that tillage must cease as soon as the potatoes blossom, is wrong. It should be continued as late in the season as the growth of the vines will permit. As the tops spread out and begin to cover the space between the rows, they partially shade the soil and thus lessen the loss of moisture by evaporation. The cultivator should be narrowed and the middle of the open space kept covered with a loose earth mulch (Fig. 34). The implement best adapted to this work is one having many smiU teeth so that it will leave the soil com- paratively level. (See Frontispiece.) Fig. 35 shows an imple-.
