Montana now ranks next to Minnesota 

 in average yields per acre of spring wheat, 

 being well ahead of North Dakota, the prin- 

 cipal spring wheat growing state. Montana's 

 ten year average yield, unless there is fur- 

 ther improvement in the average of Min- 

 nesota, promises ultimately to exceed Min- 

 nesota's when the effect of the 1917-1920 

 period of low yields has been passed. In the 

 accompanying graph is shown both the 1926 

 average yield per acre in the important 

 spring wheat states and the ten year aver- 

 ages as computed in October, 1926, from 

 preliminary estimates of yields in all of the 

 states. 



SUITABILITY OF MONTANA CLIMATE FOR WHEAT 



A variety of climatic conditions and soils characterizes the distribution of 

 wheat production throughout the world. The general requirements of wheat call 

 for a growing season of at least ninety days in length and moderate rainfall. 

 Wheat is most extensively produced, however, in areas where the average annual 

 rainfall is less than thirty inches. The bulk of Australia's production is grown 

 with less than twenty-five inches. In the United States a large part of the pro- 

 duction receives from twenty-five inches down to less than fifteen inches, with
