yield and also their rank based on their average computed yield for 

 the same 4-year period are shown in Table VIII. A brief discus- 

 sion of the results of each year will be given. 



Results in 1908. — Fifty-eight varieties and strains of winter wheat 

 were planted on tenth-acre plats in the fall of 1907. The average 

 acre yield in 1908 of the 8 varieties which were grown at Nephi in 

 1907 was 27.2 bushels, or 3.8 bushels below the average yield of the 

 same varieties in 1907. The average acre yield in 1908 of the 42 

 varieties winch were introduced from Kansas in 1907 was 26.3 bushels; 

 while the average yield of the 5 varieties from California was 14.3 

 bushels per acre. The low yields of the California varieties undoubt- 

 edly were due to their inability to survive the winter conditions, as 

 there was a high percentage of winterkilling among them. It is inter- 

 esting to compare the yields in 1908 of all varieties at Nephi with 

 their yields in 1907 and 1908 in the States from which they were 

 brought. These data are presented in Table VII. 



Table VII. — Winter wheat varieties grown at the Nephi substation, Utah, in 1908, 

 showing their origin, the source of seed planted, and the yulds in 1907 and 1908 at their 

 source compared with their yields in 1908 at Nephi.
