BARLEY 139 



some apparent exceptions in the Canadian provinces. 

 It might also be called the Manchuria barley district, as 

 the Manchuria variety is very generally and commonly 

 grown. Nearly or quite half the total barley production 

 of. North America is in this district. The states and 

 provinces of largest production are Minnesota, Wiscon- 

 sin, Ontario, and Manitoba. At the Wisconsin Experi- 

 ment Station, the average yields of different six-row 

 barleys in a five-year period ran from 32 to 51 bushels an 

 acre. The Oderbrucker, equivalent to Manchuria, was 

 found to be the best in yield, and has become the domi- 

 nant barley of the state and is now commonly grown 

 in adjacent territory. At the Minnesota station Man- 

 churia yielded 45 to 50 bushels an acre, while two-row 

 varieties made 37 to 41 bushels. In Ontario similar re- 

 sults have been obtained. At Brandon, Manitoba, in a 

 five-year test six-row barley yielded 60 to 67 bushels and 

 two-row barley 50 to 67 bushels an acre. In eastern 

 South Dakota, the Odessa six-row has given better results 

 for a long time than any other six-row variety, even in- 

 cluding selections. A little farther westward, both in 

 the United States and Canada, the two-row varieties soon 

 equal the six-row, and finally exceed them in yield.
