Fig. 5.—Wheat growing on plat on which rye was grown and plowed under in 1908. (See figure 1, F.) land and all were plowed to a depth of 6 inches and harrowed. Plat 1 was allowed to remain fallow. Plat 4 was sown to wheat. Plats 2, 3, 5, and 6 were sown, as indicated, to horse beans, Canadian field peas, rye and vetch, and rye alone. The vetch in plat 5 made a very poor stand, while the horse beans and peas made a fairly good stand. The stand of rye was excellent. In March, 1908, plats 1, 2, 3, 5, and 6 were plowed 8 inches deep, harrowed, and kept clean throughout the summer and fall. Plat 4, 178.
