EXPERIMENTS WITH DURUM WHEAT.

two years. The resulting data from these and from representative 

 varieties of the Fife and Preston groups are shown in graphic form 

 in figure 12. In the 11-year period, the durum variety is seen to 

 outyield Red Fife by 8.1 bushels and Preston by 11.2 bushels per 



acre. 



RESULTS AT INDIAN HEAD, SASKATCHEWAN. 



The Indian Head Experiment Farm has an average annual pre- 

 cipitation of 19.4 inches, based on a record covering 10 years. It 

 is maintained by the Canadian Department of Agriculture, and the 

 results given in Table XXVI are taken from the published annual 

 reports (Canada Experimental Farms, 1896-1908).

 varieties of common wheat grown on the Indian Head (Saskatchewan) Experiment Farm , 

 during periods of varying length in the thirteen years from 1895 to 1907, inclusive.

The experiments extend from 1895 to 1907, a period of 13 years. 

 The same varieties are included as at Brandon, viz, a durum called 

 Goose, probably Arnautka, with Preston and Red Fife, two spring 

 common wheats. As at Brandon, two other durum varieties, Mah- 

 moudi and Yellow Gharnovka, are included during the last five and 

 four years, respectively. Arnautka outyielded the other two durums 

 in the short period during which all were grown. In the 13-year 

 period it outyielded Preston by 1.8 bushels and Red Fife by 1.9 

 bushels per acre. A market for durum wheat was not developed in 

 Canada, so the wheat was not recommended for general cultivation 

 by the Dominion Cerealist, and finally the varieties were discon- 

 tinued from experimental tests. 



RESULTS IN THE ARID BASIN AND COASTAL AREAS. 



This geographic division includes most of the territory west of 

 the Rocky Mountains. In the basin area are included the States and 

 portions of States between the Rockies and the Sierra Nevada and
