WILLISTON, N. DAK. 
Varietal tests of barley were conducted at the Williston (N. Dak.) substation 
in cooperation with the^ North Dakota Agricultural Experiment Station from 
1908 to 1918, inclusive. Records of j'ields of 1920 and 1921 were obtained through 
the courtesy of the North Dakota Agricultural Experiment Station. The an- 
nual 3'ields are shown in Table 41. Four groups of barley were compared, of 
which the Manchuria and Hanna were practically equal in rank, while the Thorpe 
ranked higher than the Hull-less. In the summarized digest of Table 41 the 
yields of eight well-known varieties are compared. Tartar (C. I. No. 1116) 
{produced slightly higher yields than Hannchen (C. I. No. 531). Yields prac- 
ticallv equal to those of Tartar and Hannchen were obtained from Manchuria 
(C. i: No. 882). Hanna (C. I. No. 203) was fourth and Svanhals (C. I. No. 187) 
fifth in point of yield. Tartar (C. I. 1116) is a selection made from the same 
stock as Trebi (C. I. No. 936). Under irrigation in southern Idaho Trebi has 
proved to be a highly productive variety. Tartar has not been widely tested, 
and its value is not known. Disregarding the Tartar, it would seem that the 
Manchuria barleys were probably slightly superior to the 2-rowed sorts at 
WiUiston. This means that the line separating the districts where Manchuria 
is superior from that in which the 2-rowed barleys grow best runs in a north- 
westerly direction through North Dakota. 
BROOKINGS, S. DAK. 
Yields are reported in this bulletin from several stations in South Dakota. 
These data are available only for those j^ears in which the work was carried on in 
cooperation at the various South Dakota stations or, in some cases, where the 
yields in other yesLTS have been published in bulletins of the State station. It is 
thought that the conclusions which are drawn from the results are not affected 
by the missing years. 
In Table 42 yields are reported from a large number of varieties grown at 
Brookings in one or more of the years from 1902 to 1919, inclusive. To facili- 
tate the study of the results six different groups of varieties were compared. The 
Manchuria was much superior to the other five groups. The Hanna, Chevalier, 
and Thorpe, in the order given, ranked next. The Coast group was not repre- 
sented in this comparison, but probably would have been inferior to the four 
named. 
In Table 42 the yields of 11 varieties representative of several different groups 
are compared. These are not necessarily the highest yielding ones of their groups. 
They are, however, well-known varieties which are of interest both because they 
are representative of a group and are widely grown. Of the 11 varieties com- 
pared the highest yield was obtained from Odessa (C. I. No. 182), which seems 
particularly adapted to eastern South Dakota. Manchuria (C. I. No. 241) was 
almost the equal of Odessa. The third variety in point of yield was Gatami 
(C. I. No. 575), which was tested in only a few years and was comparable with 
some of the varieties in only one year. Its place, therefore, is not conclusively 
determined. Following Gatami are three 2-rowed varieties of almost equal 
value. These are Gold (C. I. No. 1145), Svanhals (C. I. No. 187), and White 
Smyrna (C. I. No. 195). In recent j^ears three selections have shown promise. 
These are Manchuria (C. I. No. 2156), Manchuria (C. I. No. 2155), and Odessa 
(C. I. No. 2154). Oderbrucker (C. I. No. 1146) also yielded well. 
It is apparent from the original data (Table 42) and the summarized 
digest that barlej's of the Manchuria type have produced the highest yields 
in eastern South Dakota. Odessa has given somewhat better yields than the 
best strains of either Manchuria or Oderbrucker. This variety belongs to the 
same general group as the Manchuria. Selections have been made from Odessa, 
however, which differ very much from the Manchuria barleys. Odessa (C. I. 
No. 182) as tested in South Dakota, while containing a few of these variant types, 
was of the same general character as Manchuria. The advantage of early ripen- 
ing, which is so important in western South Dakota, was seen to have some in- 
fluence even at Brookings, for both Gatami and White Smyrna gave fairly good 
yields. Nepal (C. I. No. 595) produced very low yields at Brookings but not 
much lower than at most points in the Mississippi Valley.
