Of the varieties grown at Brookings for the seven years from 
1906 to 1912 the best average acre yields were produced by the Sixty- 
Day, 43.5 bushels, and the Swedish Select, 39.2 bushels. These 
} T ields were considerably higher than those of any other variety in 
the test, exceeding those of the Banner, which, as already noted, is 
quite typical of the oats generally grown in the State, by 13.9 and 
9.6 bushels, respectively. 
Similar data are shown in Table VIII for the trials at Highmore, 
which are representative of the central portion of the State. At 
that point it will be noted that there were two total failures, though 
in the area as a whole there was only one — that of 1911. Of the 
varieties here recorded five yielded less than 20 bushels per acre, 
and were therefore produced at a loss. The average for all varieties 
reported for all years shows a profit of 4 per cent of the cost of pro- 
duction, while on the best variety there was a profit of 33 per cent of 
the cost of production. It is evident, therefore, that the profit or 
loss in growing oats under conditions similar to those at Highmore 
during the seven years from 1906 to 1912 would have depended upon 
the variety used. 
The highest average yields at Highmore were produced by the 
Swedish Select and Kherson varieties. The Swedish Select averaged 
26.7 bushels to the acre for the 7-year period from 1906 to 1912; 
the Kherson, 24.2 bushels; and the Sixty-Day, 22.9 bushels. The 
Sixty-Day was slightly exceeded in yield by the Belyak and the Red 
Algerian.
