CEREAL INVESTIGATIONS ON THE BELLE FOURCHE FARM. 4] 
for the six years was 21.2 bushels, of the best durum 11.8 bushels, and 
of the best sprmg common 11.1 bushels. 
The best average yields of oats for the six years were obtained from 
the Sixty-Day and Kherson varieties. The returns from this crop 
were much lower than from winter wheat and slightly lower than 
from spring wheat. 
The best rate of seeding for small-kerneled early varieties of oats, 
sueh as the Sixty-Day and Kherson, is about 6 pecks to the acre. 
The returns from barley were even less satisfactory than those from 
oats. The best average yield for the six years was only 10.7 bushels, 
and for the five years from 1909 to 1913, only 9.7 bushels. The most 
satisfactory varieties are those which mature early, such as the 6- 
rowed varieties, Gatami and Odessa, and the 2-rowed variety, White 
Smyrna. 
The yields obtained from winter rye and from winter and spring 
emmer have been much lower than those from the other cereals. 
_ These crops can not now be recommended for western South Dakota. 
The best yield from flax in a 2-year test was obtained from the 
Select Russian variety. It is probable that the best results will be 
obtained if this crop is sown as early as good germination and 
growth may be expected. 
The following varieties are recommended for the Belle Fourche 
section: 
Winter wheat.—Kharkof, Turkey, Crimean. 
Spring wheat—Kubanka durum, Arnautka durum, Power Fife, Marquis. 
Oats.—Sixty-Day, Kherson. 
Barley.—Odessa, Gatami, White Smyrna.
