CEREAL INVESTIGATIONS OK THE BELLE FOTJRCHE FARM. 41 



for the six years was 21.2 bushels, of the best durum 1 1.8 bushels, and 

 of the best spring 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, 

 such 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.
