10 DEY-LAND GRAINS FOR NORTH AND SOUTH DAKOTA. 



BELLEFOURCHE. 



The highest average yiehl of sj)ring wheat at Bellefourche is 23.2 

 bushels per acre, as shown in Tabk^ III. This was obtained from two 

 strains of the Kubanka variety, G. I. No. 1440 '^ (better known as 

 S. P. I. No. 5639) and G. I. No. 1516.'' Several other varieties have 

 yielded nearly as much. 



Of the common wheats, Powers' Fife (G. I. No. 3025) has yielded 

 the most, 17.9 bushels per acre, or 5.3 bushels less than the Kubanka. 

 Kysting's Fife (G. I. No. 3022) is a close second. The Bearded Ked 

 Fife, which has yielded well at Highmore, has not been included in 

 these tests. Several strains of this valuable variety are being grown 

 m the })lant nursery. Some of these are very promising and will be 

 grown in comparison with the other varieties as soon as sufficient seed 

 is obtained. 



HIGHMORE. 



The Kubanka variety (G. I. No. 1516) has produced the highest 

 average yield of the durum wheats at Highmore, 22.4 bushels per acre 

 for the seven-year period from 1903 to 1909, as shown in Table IV. 

 The Ghirka Spring, the only common spring wheat grown for the full 

 period of seven years, gave an average yield of 14.5 bushels per acre. 

 The Bearded Red Fife has produced the highest average 3deld of the 

 common wheats for the five years from 1905 to 1909. Three varieties, 

 Pedigreed Bluestem, Minnesota No. 169, and Okanogan Valley Velvet 

 Chaff, have each produced an average yield of about 1.5 bushels below 

 that of the Bearded Red Fife. 



The common and durum wheats have bee'n grown on similar ground, 

 with the exception of the 1909 crop. A comparison of yield of the 

 two groups in 1909 can not be made for that reason. The average 

 yield of the Bearded Red Fife variety for the four years from 1905 to 

 1908 is 19.5 bushels per acre, or 7.5 bushels less than the yield of the 

 Kubanka for the same period. The former, however, is at present, 

 1910, discriminated against by the millers, although not to the same 

 extent as is the durum wdieat. Its greater yield, as compared with 

 other varieties of common wheat, is for that reason partly ofl'set 

 by the lower price usually received for it. The Kubanka variety 

 averages nearly 9 bushels more than the Pedigreed Bluestem, the 

 second common wheat in jjoint of yield, an increase of more than 

 48 per cent.

b The following strains of the Kubanka were obtained by Mr. M. A. Carleton: G.I. 

 No. 1440 in December, 1900, from Uralsk territory, Russia; G. I. No. 1516, from the 

 Paris Exposition in 1900 (originally from the Samara government, Russia); G.I. No. 

 1541 (S. P. I. No. 6009), from the Astrakhan government, Russia, in August, 1900; and 

 G. I. No. ir!.54 (S. P. I. No. 2758), from the Samara government, Russia, in 1898.
