CEREAL INVESTIGATIONS ON THE BELLE FOURCHE FARM.

the Manchuria, is a bearded wheat which does not belong to any 

 group now commonly grown in this country. 



Table X shows the average date of heading and of maturity, 

 height, and weight per bushel of these 10 varieties in 1908, 1909, 1910, 

 and 1913. In 1911 none of the varieties matured grain, so that 

 none of these data are available for that year, while in 1912 data 

 were obtained for 

 only two or three 

 varieties.

Fig. 2. — Diagram showing the average yields per acre, in bushels, of 

 the leading varieties of spring wheat at the Belle Fourche Experi- 

 ment Farm, for six years, 1908 to 1913, inclusive. 



Table X also shows 

 the average yields per 

 acre of grain and of 

 straw for these vari- 

 eties. The yield of 

 grain is the average 

 for the entire period 

 of six years, 1908 to 

 1913. These yields are shown graphically in figure 2. The yield of 

 straw is for five years, 1912 being excluded for the reason that only two 

 of the varieties were harvested, though all of them made some growth. 

 The groups and varieties are arranged in the table according to their 

 average yield of grain per acre.

LEADING VARIETIES OF SPRING WHEAT. 



As shown in Table X, the best yields of spring wheat at Newell have 

 been obtained from the durum varieties, Kubanka and Arnautka. 

 Some of the varieties of common wheat, however, have produced
