CEREAL INVESTIGATIONS ON THE BELLE FOURCHE FARM. 19. 
Kubanka is higher. The best durum aon to grow in western South 
Dakota is the Kubanka. A field of this variety on the Belle Fourche 
Experiment Farm is shown in figure 4. 
Common wheat.—All the spring common wheats which have been 
erown at Newell for more than one year have hard or semihard red. 
kernels. They vary chiefly in the hairiness of the chaff, in the pres- 
ence or absence of beards, and in the quality of the grain. 
The highest yield of the spring common wheats has been produced 
by a variety called Manchuria, C. I. No. 2492. The average yield 
of this variety for six years is 11.1 bushels, slightly less than that of 
the best durum wheats. The Manchuria is an early, bearded variety, 
with hairless, brown chaff, and medium-sized, semihard, red kernels. 
It has produced fairly good yields at Newell because of its earliness. 
Its milling qualities are poor and it is not to be recommended. i 
Fic. 4.—Plats of Kubanka durum wheat on the Belle Fourche Experiment Farm in 1910. 
Three varieties of Fife wheat have given slightly lower yields than’ 
the best durum wheats. These three Fife wheats are the Power, 
Rysting, and Ghirka. The Power and Rysting are somewhat later 
in heading than the durum varieties, but mature at about the same 
time. The Ghirka is slightly earlier than any of the durums. 
The Fife is one of the standard groups of hard red spring wheat in 
Minnesota and the Dakotas. The Fife wheats all have slender, rather 
open, beardless heads, with white, hairless chaff. 
If common spring wheat is to be grown in western South Dakota, 
some variety of the Fife group should be chosen. In addition to the 
three here mentioned, the Marquis, a variety which originated in 
Canada and which tes given excellent results in the Canadian Prairie 
Provinces, is worthy of trial. Iti is very early in maturing and i is of
