TESTS OF BARLEY VARIETIES IN AMERICA 131 
Although the barleys grown in recent years at Union have not been tested 
sufficiently to show their relative value, the behavior of Trebi, Club Mariout, 
and Flynn here and in other sections of Oregon indicates that they would be 
desirable sorts to grow. 
BURNS, OREG. 
Dry-land oondiiions. — The yields of barley varieties grown on dry land at the 
Harney Valley Branch Station, Burns, Oreg., were obtained in cooperation with 
the Oregon Agricultural Experiment Station for the seven years from 1913 to 1919, 
inclusive, and through the courtesy of that station for the years 1920 and 1921. 
Burns is situated in an old lake bed on a high plateau between the mountain 
ranges. The annual precipitation is low, and although there are no such extreme 
climatic changes as in the humid States frosts may occur in any month of the 
year. Because of this fact and the low rainfall, there is only one good crop in 
about every three on the dry land. The yields of varieties tested on dry land 
are shown in Table 74. 
In the summarized digest of Table 74 a comparison of 12 well-known varieties 
is shown. The 2-rowed sorts, Hannchen (C. I. No. 531) and White Smyrna 
(C. I. No. 195), produced the highest yields. The data in Table 74 indicate 
that Hannchen was usually the better of the two in the years of heavier rainfall 
and that in the drier years the reverse was true. Following White Smyrna 
was Coast (C. I. No. 690), which was the best of the 6-rowed barleys compared. 
Svanhals (C. I. No. 187) was fourth in point of yield. Winter Club (C. I. No. 592) 
grown as a spring variety gave fair results. It was the poorest of the varieties 
compared, however, when fall sown. As can be seen from this table, the barleys 
of the Manchuria group are entirely out of their region of adaptation. The 
hooded and hull-less varieties, Horsford (C. I. No. 610), Nepal (C. I. No. 595), 
and Black Hull-less (C. I. No. 596), also produced very low yields. 
In the fail of 1912 two spring and four winter varieties were sown. They 
produced low yields as compared with the spring-sown varieties, probably 
owing to both lack of precipitation and partial winterkilling. Winter Club 
(C. I. No. 592) and Tennessee Winter (C. I. No. 257) were the only fall-sown 
varieties tested further. Neither of these could compete at all with those 
which were spring sown. Trebi (C. I. No. 936) was grown in 1919 and 1920, 
but it is evident that it can not succeed here without irrigation. 
Hannchen and White Smyrna are unquestionably the superior varieties on 
the dry lands. At the stations in eastern Oregon the 2-rowed varieties have 
yielded relatively higher than elsewhere in the region west of the Rocky Mountains 
although they have been promising at many other places. 
Irrigated land. — Barley varieties have been tested on irrigated land at the 
Harney Valley Branch Station, Burns, Oreg., for the five years from 1917 to 1921, 
inclusive. The data were obtained in cooperation with the Oregon Agricultural 
Experiment Station for the years 1917 to 1919, inclusive, and through the courtesy 
of that station for the years 1920 and 1921. The annual yields of these barley's are 
found in Table 75. While it is difficult to compare the varieties when grown for 
such varying periods of years, it is obvious that Hannchen (C. I. No. 531), "VMiite 
Smyrna (C. I. No. 658), and Trebi (C. I. No. 936) were superior sorts at this 
station v/hen tested under irrigation. Coast (C. I. No. 690) was inferior to these 
varieties in all the years for which it was comparable with them with the exception 
of 1920, when it gave the unusually high yield of 81.3 bushels, the highest in that 
year. Svanhals (C. I. No. 187) was fourth in point of yield. Under irrigation. 
Winter Club (C. I. No. 592) was quite successful when spring sown. It gave 
the highest average yield of all the varieties grown during the vears 1917, 1920, 
and 1921. Trebi (C. I. No. 936) was tested only in the years 1919 and 1920 but 
gave the highest average for those years. The hooded barleys Nepal (C. I. No. 
595) and Horsford (C. I. No. 610) were inferior in yield. 
While both Trebi and Winter Club are promising sorts, their values are not so 
well established as those of Hannchen and White Smyrna.
