An area of 2,999 acres of alfalfa was also seeded without a nurse crop, from which no yields have been reported. This area added to the 47,251 acres shown in the table makes the total area of 50,250 acres actually Fig. 2.—Plats occupied by rotation 65, which consists of corn, flax, oats, and three years of alfalfa. The corn and the third-year alfalfa are pastured off by hogs. EXPERIMENTS WITH IRRIGATED FIELD CROPS. ROTATION OF CROPS UNDER IRRIGATION. In order to determine the relative Yalues of different crop sequences for local irrigated conditions, eighty |-acre plats are devoted to crop- rotation work. On these plats 31 rotations are carried, including alfalfa, sugar beets, corn, flax, oats, potatoes, and wheat, which are 1 These experiments arc un
