Fic. 24.—Averaze actual acre yields and average net acre yields obtained from sowing Turkey winter wheat 
at different rates, varying from 2 to 8 pecks per acre, in the 8-year period from 1914 to 1921, inclusive, at 
the Sherman County Branch Station, Moro, Oreg. The net yields are the actual yields minus the 
quantity sown. 
1914 and 1915, but the yields for these years are averages obtained 
from duplicate tenth-acre plats. In the years 1916 to 1921, inclu- 
sive, the yields from each rate are averages of the three twentieth- 
acre plats used for the three earliest dates of sowing, as shown in 
Table 27. The results are summarized graphically in Figure 24. 
The average yields obtained from the different rates of sowing are 
remarkably similar, indicating that on well-cultivated summer-
