AKRON. COLO. 
The barley yields at the Akron field station (Table 64) were obtained in coopera- 
tion with the Oifice of Dry-Land Agriculture Investigations. Ten important 
varieties are compared in the summarized digest of the table. Smyrna (C. I. No. 
2642) is the best of the varieties included in the comparison. It was not grown in 
the same years as Hannchen (C. I. No. 531), Primus (C. I. No. 532), or ]\lanchuria 
(C. I. No. 244), so that a comparison with these varieties can not be made. 
Following Smyrna is Hannchen (C. I. No. 531). In 1915 this variety became 
confused with another. As a consequence, no comparison can be made after 
1914. Orel (C. I. No. 2190) is third in point of yield. This strain is thought 
to be identical with Orel (C. I. No. 351), which was grown from 1917 to 1921, 
inclusive. However, Orel (C. I. No. 351) was surpassed by Coast (C. I. No. 690) 
as well as by the two Smyrna varioties in this later period. ^ Orel is usually 
grown as a winter barley, and it is of interest that it is a high-yielding sort when 
so"^Ti in the spring at Akron. Coast (C. I. No. 690) was almost the equal of 
both Hannchen and Orel. For the 14 years of the experiment Coast produced 
an average yield of 113 per cent of the weighted mean. Hanna (C. I. No. 203) 
and Manchuria (C. I. No. 244) follow in the order named. Blackhull (C. I. No. 
878) was superior to Primus (C. I. No. 532), Baku (C. I. No. 709), and Horsford 
(C. I. No. 877) . (See PI. Ill, fig. 2, A and B.) Grown for thefuU period of the 
experiment, 1908 to 1921, inclusive, its average yield was 92 per cent of the weighted 
mean. Blackhull has yielded better at Akron than at most of the other stations, 
and those who have been in charge of the testing think that the uniformity of 
its yields and other excellent qualities make it a desirable variety. As can be 
seen in Table 64, the winter barleys, Tennessee Winter (C. I. No. 257), Arlington 
Awnless (C. I. No. 702), and Nakano Wase (C. I. No. 754), which were grown 
during different periods, were not high-yielding sorts as compared with the 
spring varieties. 
While the 2-rowed barleys are undoubtedly the highest yielding sorts at 
Akron, it is evident that Coast is also well adapted to this district. It appears 
that Akron, Archer, and Fort Collins are all near the border line between the 
2-rowed and Coast districts. Where the yield is equal, farmers usually prefer 
6-rowed varieties, as the straw of the 2-rowed ones is often weak and in White 
Smyrna is very short. 
SANDPOINT, IDAHO 
The yields of barley varieties at the Sandj^oint substation for the years 1920 
and 1921 were obtained through the courtesy of the Idaho Agricultural Experi- 
ment Station. These yields are found in Table 65. As the crop of 1921 was 
almost a failure, the yields for this year are of little value in determining the 
relative importance of the varieties grown. Han River (C. I. No. 206) produced 
the highest average vield for the two vears of the experiment, while White Smvrna 
(C. I. No. 910) ranked second. Baker (C. I. No. 975), Trebi (C. I. No. 936), 
and Peruvian (C. I. No. 935) follow in the order named. Winter Club (C. I. 
No. 488) was grown only in 1921, but was exceeded by both White Smyrna and 
Peruvian.
