EXPERIMENTS WITH DURUM WHEAT. 
Among the varieties distributed, the Kubanka and Arnautka proved 
to be well adapted. 
Production increased rapidly during the early years. It rose 
from 60,000 or 70,000 bushels in 1901 to about 6,000,000 or 7,000,000 
bushels in 1903, and probably about 50,000,000 bushels by 1906. 
As noted in the discussion of its history, the development of the 
market did not keep pace with the increased production. For this 
reason the price, which had always been less than that of common 
wheat, dropped to even lower levels, the difference sometimes 
amounting to 20 or 25 cents a bushel. This low price so discouraged 
the growers that the production in 1909 was slightly less than 
40,000,000 bushels. 
The census figures, taken for the crop year 1909, show that 87 J 
per cent of the durum wheat produced in the United States that

year was grown in North Dakota and South Dakota. Minnesota 
ranked third in production, with about 7 per cent of the total crop, 
and practically all of the remaining 5 or 6 per cent was grown in 
Nebraska, Kansas, Colorado, Wyoming, and Montana. Figure 2 is 
an outline map of the northwestern United States, illustrating the 
production of durum wheat in 1909. 
Since 1909 the Bureau of Crop Estimates of the United States 
Department of Agriculture has gathered annual data upon the 
acreage and production of durum wheat in the three States of Min- 
nesota, North Dakota, and South Dakota. In 1915 Montana was 
added. Table I shows the estimated annual production of durum 
wheat and of all other wheats and the percentage of durum in the 
total wheat production in the three States named during the eight 
years from 1909 to 1916, inclusive.
