churia group, Featherston (C. I. No. 1120) and Manchuria (C. I. No. 956), 
were third and fourth, respectively. Lion (C. I. No. 923), a 6-rowed smooth- 
awned barley, also gave a high average yield. Oderbrucker (C. I. No. 537) 
produced the highest yield of the five varieties introduced in 1920. It was, how- 
ever, surpassed by Trebi, Sandrel, and Lion. The 2-rowed sorts were quite 
inferior. Frankish (C. I. No. 953) and Horn (C. I. No. 926) were the only ones 
w^hose averages exceeded that of the weighted mean. While a 3-year test is not 
of sufficient length to make any definite statements regarding the value of the 
individual varieties, it would seem that there is an overlapping of growing con- 
ditions here. Barleys of the Manch\iria group and such varieties as Sandrel 
and Trebi, usually grown under the more arid conditions of the Western States, 
gave relatively high yields in this locality. The barley commonly grown in this 
region, however, is of the Manchuria-Oderbrucker type. 
The Missouri station has conducted barley experiments at four of its soil- 
experiment fields. These are located at Lewistown, Warrensburg, Carthage, 
and Maryville, Mo. At each of these places four varieties were tesi^d, two of 
which, Manchuria (C. I. No. 244) and Horsford (C. I. No. 507), were carried at 
all of them. 
At Lewistown Manchuria (C. I. No. 244) and Oderbrucker (C. I. No. 537) 
produced the best yields, the former having been grown in the years 1911 and 
1912 and the latter in 1912 only. Horsford (C. I. No. 507), grown in 1911 and 
1912, and Nepal (C. I. No. 595), grown in 1911, did not compare favorably with 
the other two. 
At Warrensburg these same four varieties were tested during the years from 
1914 to 1916, inclusive, and in 1920 and 1921. Manchuria (C. I. No. 244) was 
again the leading variety, but Horsford was superior to Oderbrucker at this 
station. Nepal (C. I. No. 595) gave such a low yield in 1914 that it was not 
continued further in the experiment. 
The results at Maryville are quite comparable to those at Warrensburg. 
Oderbrucker (C. I. No. 537) was first in point of yield, Horsford (C. I. No. 507) 
second, Manchuria (C. I. No. 244) third, and Black Hull-less fourth. The 
Manchuria and Oderbrucker varieties belong to the same varietal group and are 
almost identical. At Warrensburg, however, Manchuria gave the higher yields. 
Varieties were tested at Carthage during the years 1910 and 1911. Oder- 
brucker was not grown at this station, but both Nepal and Black Hull-less were 
included. Manchuria (C. I. No. 244) was again the leading variety, with Hors- 
ford following. The Hull-less varieties Nepal (C. I. No. 595) and Black Hull-less 
(C. I. No. 596) were grown for only one year, Nepal in 1910 and Black Hull-less 
in 1911, and were the lowest in point of yield in these years. 
Results at these four stations indicate that Manchuria (C. I. No. 244) and 
Oderbrucker (C. I. No. 537) .were the best of the varieties tested. At both Mary- 
ville and Warrensburg, however, Horsford gave relatively higher yields than is 
usually the case. 
FARGO, N. DAK. 
Varietal tests of barley have been made at the North Dakota Agricultural 
Experiment Station at Fargo since 1892. There were developed at this station 
a number of strains which have been tested at other places. The North Dakota 
station, like those of Minnesota, Wisconsin, and Ontario, was a center for the 
distribution of varieties to other stations. It is an important link in the tracing 
of varieties. At Fargo, as at many other places, the same variety was introduced 
more than once and in some cases was carried under different numbers at the 
same time. Manchuria (C. I. No. 244) was grown under North Dakota Nos. 
788 and 792 for eight years. The average yield of the variety under each of these 
two numbers was exactly the same at the end of this period. The average 
deviation from the mean was only 0.9 bushel, while the maximum deviation 
from the mean was only 1.6 bushels. This is of special interest, since many 
agronomists feel that the earlier tests, which were conducted without any rep- 
lication of plats, are not of significant value. It is unlikely that the slight varia- 
tions of yield shown by these two varieties are typical of what might be expected. 
Probably the actual accuracy is far less than is indicated by this comparison. 
The writcis feel, however, that the value of this early work has been under- 
estimated. Certainly, the deviation from the mean was very slight when com- 
pared with an average yield of more than 38 bushels. 
The data reported in TaV^le 36 were obtained through the courtesy of the 
North Dakota Agricultural Experiment Station. A group digest of the varieties 
was made, which showed the Manchuria group to be the best of six compared.
