OATS. 



Their Importance. The production of oats is confined to the 

 Temperate Zones. The crop does best in cool climates and will not 

 thrive in the warmer regions unless the water supply is ample. It 

 reaches its best development in Norway, Sweden, Germany, Great 

 Britain, and Canada, and in the United States in Washington, 

 Idaho, and Montana. Good spring oats are seldom produced in 

 the southern part of the United States or in southern Europe, while 

 the northern limit of production is near the Arctic Circle, in Norway 

 and Alaska. The crop is very generally grown in the central and 

 northern portions of the North Temperate Zone. The world pro- 

 duction of oats in bushels is greater than that of either corn or 

 wheat, but as its weight per bushel is much less, the total produc- 

 tion in pounds is smaller than that of either of those crops. The 

 greater portion of the oat crop of the United States is fed on the 

 farms wnere it is grown. 



Chemical Analyses. The chemical composition of oats, oat 

 straw, oat hay, and the green plant, together with similar analyses 

 of other grains for comparison is shown in the following table:
