1 Of the acreage shown here, 9,931 acres was in 1912 seeded to alfalfa, with nurse crops of wheat, oats, or 

 barley, the grain yields of the nurse crops being included under the headings of wheat, oats, and barley, 

 respectively. 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 irrigated.

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
