WHEAT, OATS, AND BARLEY IN SOUTH DAKOTA.

the number of bushels produced in excess of the average cost and thus 
represents the profit obtained. 
In determining which variety to grow in any given locality it is 
necessary to consider the milling quality, the time required from 
seeding to maturity, and the yield. These points will be discussed in 
subsequent paragraphs with regard to each of the leading varieties. 
The data in Table IV are arranged to present a comparison of the 
producing capacities of the two principal climatic areas of the State. 
This table shows that the average yields of the groups of improved 
varieties discussed in this bulletin, with one exception, have been 
greater than the average for the entire State from miscellaneous

Fig. 2. — Diagram showing the average production in bushels to the acre of the leading 
varieties of each type of wheat grown at Brookings and Highmore, S. Dak., for the 
eight years from 1905 to 1912, inclusive. The vertical line indicates the yield neces- 
sary to cover the estimated cost of production. 
varieties or mixtures. The one exception is the beardless fife group 
at Highmore. Considering that there have been two total failures 
at Highmore, this superior showing is a striking indication of the 
value of using good seed of productive varieties.
