TESTS OF BAELEY VARIETIES IN AMERICA

and on poor lands, none has yet been found that will produce as much grain on 
fertile soil as varieties of the Tennessee Winter group. 
JACKSON, TENN. 
Two varieties of barley, Union Winter (C. I. No. 583) and Beardless 20 
(C. I. No. 2745), were tested at the Jackson substation during the years 1915, 
1916, 1917, 1919, 1920, and 1921. The yields of these varieties (Table 89) 
are used through the courtesy of the Tennessee Agricultural Experiment Station. 
Union Winter produced an average yield of 19. 5 bushels for the six years, as 
compared with 16.5 bushels for Beardless 20. At Knoxville Union Winter was 
superior to all other varieties tested. It is a barley of the Tennessee Winter 
group which seems to be particularly well adapted to this region. Beardless 20, 
a hooded variety, produced good yields in all of the years it was grown with the 
exception of 1920. The hooded winter barleys are not, however, as high yielding 
as those of the Tennessee Winter type.

FAYETTEVILLE, ARK. 
The data from the Arkansas Agricultural Experiment Station at Fayetteville 
were furnished through the courtesy of that station. Only winter barley was 
grown, usually in connection with experiments with winter w^heat and oats. 
Comparative tests of these three cereals were conducted during the period from 
1915 to 1921, Inclusive. According to information received from this station, 
good stands were established each season. No winterkilling due to low tem- 
perature or to heaving vras observed. The crop proved more hardy than Turf 
oats, but is less hardy than either winter wheat or rye. Arkansas undoubtedly 
is in the humid winter-barley district where the varieties of the Tennessee Winter 
type are probably the ones generally cultivated. As this was not a varietal 
experiment, no varietal names were mentioned in the data received. 
STILLWATER, OKLA. 
The data on barley yields at Stillv\^atec, Okla., were furnished through the 
courtesy of the Oklahoma Agricultural Experiment Station. While these data 
were not adequate for tabulation, they are of enough significance to warrant 
consideration. Barley is becoming much more important as a feed crop in this 
section, but the experiments with this cereal so far have been very limited. 
For this reason any information as to types grown is of value. 
In 1920 the best results were obtained from the fall-sown varieties. A jdeld 
of 53.3 bushels was procured from a 6-rowed club barley, which is probably the 
variety known as Winter Club. It has been grown for many years in small 
localized areas in the Western States, particularly in Utah, where it is known 
as Utah Winter. Another 6-rowed variety, thought to be a barley of the Ten- 
nessee Winter group, is commonly grown in the vicinity of Stilhvater. It pro- 
duced the relatively low yield of 26 bushels, but an improved selection of this 
variety yielded 32.2 bushels. The barle3^s sown in the spring of 1920 were 
practically failures. Scarcely more than enough seed for 1921 was obtained 
from these plats. 
The fall-sown barleys also were the higher yielding sorts in 1921. The com- 
mon 6-rowed barley, which is thought to be of the Tennessee Winter type, 
yielded 36.6 bushels. It was again surpassed by the improved strain just men- 
tioned, which this year produced 50.1 bushels. Results with the spring varieties
