WHEAT, OATS, AND BARLEY IN SOUTH DAKOTA.

on the cost of production, but the Hannchen (S. Dak. No. 20, C. I. 

 No. 531) and the Bohemian (S. Dak. No. 27, C. I. No. 27) have 

 returned a profit of 44 per cent. The profit obtained from these 

 selected varieties shows the value of pure strains of superior merit. 

 At Eureka the best yielding variety, the Hannchen, has been grown 

 at an average loss of 15 per cent for the four years from 1909 to 

 1912, and the three varieties tested have been produced at an average 

 loss of about 33 per cent. The two varieties grown at Cottonwood 

 returned only about 10 per cent of the cost of production during the 

 four years of the test. For the entire State the average production 

 was 22.3 bushels for the eight years (Table XIV), or 6.3 bushels 

 more than the equivalent of the estimated cost of production (16 

 bushels). This is a profit of about 40 per cent.

From a commercial standpoint the growing of pure varieties is of 

 even greater importance in the production of barley than of oats or
