averages is 11.7 bushels. 



The results reported in Table XIII show that the highest average 

 yields in the 8-year test at Brookings, 33.8 bushels to the acre, were 

 produced by the Odessa (6-rowed) and the Kitzing (2-rowed) 

 varieties. The Manchuria, another 6-rowed variety, has yielded 

 better than any 2-rowed variety except the Kitzing. In general, 

 it appears that the 6-rowed barleys are to be preferred in eastern 

 South Dakota. The reverse is true at Highmore, as the six 2-rowed 

 varieties which have been grown for eight years (1905 to 1912) 

 have averaged 21.6 bushels to the acre, while the Manchuria (Minn. 

 No. 6), a 6-rowed variety, has averaged only 18.7 bushels. The 

 highest average yield for this period, 23 bushels to the acre, was pro- 

 duced by the Bohemian and Hannchen varieties. Figure 9 shows 

 graphically the average yields of the leading varieties at Brookings 

 and Highmore. The Hannchen has given the best results at Eureka 

 in the four years from 1909 to 1912. At Cottonwood only two varie- 

 ties, the Hannchen and Manchuria, have been grown. Neither of 

 these varieties has produced a profitable crop at this station in any 

 of the four years the test has been conducted. 



If it is again assumed that the production of 16 bushels to the 

 acre will pay the cost of production, all the varieties of barley at 

 Brookings were grown at an average profit of 81 per cent on this 

 cost, while the Odessa variety (S. Dak. No. 182, C. I. No. 182) 

 returned an average profit of 111 per cent. At Highmore the 

 average profit on all varieties for eight years has been only 5 per cent
