TESTS OF BAELEY VARIETIES IX AMERICA 
85 
MANDAN, N. DAK. 
Six varieties of barley were grown at the United States Northern Great Plains 
Field Station at Mandan, N. Dak., from 1916 to 1921, inclusive. This work 
was carried on in cooperation with the Office of Dry -Land Agriculture Investi- 
gations, United States Department of Agriculture. The barley varieties, although 
few in number, represent several groups. White Smyrna (C. I. No. 195) gave the 
highest yields, as will be seen in Table 39. Hannchen (C. I. No. 531) was some- 
what less productive than White Smvrna, and Svanhals (C. I. No. IST") was 
third in point of yield. Coast (C. I. No. 690) and Club Mariout (C. I. No'. 261) 
ranked fourth and fifth, while Manchuria (C. I. No. 244) was last. Here, again, 
it is evident that the ^lanchuria barleys are not better adapted than those of 
other types. The six years reported, however, contain no years of high yields. 
It is likely that the Manchuria would produce relatively higher yields in'^years 
of greater rainfall. The best three varieties were 2-rowed sorts.

DICKINSON, N. DAK, 
The yields of barley varieties grown at the Dickinson (N. Dak.) substation 
were obtained in cooperation with the North Dakota Agricultural Experiment 
Station. Results furnished for all of the 15 years from 1907 to 1921, inclusive, 
are reported in Table 40. Only one variety, Hanna (C. I. No. 203), was grown 
for the entire peiiod. Five varieties were included for 14 years. A comparison 
is made between 10 well-known varieties in the summarized digest of the table. 
Hannchen (C. I. No. 531) gave the highest yields of the 10 varieties compared. 
Svanhals (C. I. No. 187) was almost as good as Hannchen. The average yield 
of Hanna (C. I. No. 203) was 97 per cent of that of Svanhals and Hannchen. 
Gatami (C. I. No. 575) was the best 6-rowed variety, but it was not so good as 
Wliite Smyrna (C. I. No. 658), the lowest yielding 2-rowed sort in the comparison. 
Manchuria (C. I. No. 244) was not higher than sixth in yield. Since the tests 
at Dickinson cover a period of 15 years, the results are much more conclusive 
than those at Edgeley or ]\Iandan. The best vaiieties at Dickinson are un- 
questionably 2-rowed sorts. At Lethbridge, Alberta, they were also superior. 
It would seem that the ecological conditions that favored this type of barley in 
southern Alberta obtain in western North Dakota.
