The average yields of the eight varieties are shown graphically 

 in figure 12. 



The White Smyrna (Ouchac, C. I. No. 658), a 2-rowed hulled 

 variety, has given the highest annual and average yields. The 

 Hannchen (C. I. No. 531), also a 2-rowed variety, has yielded weU. 

 In the 6-rowed hulled group, the Coast (C. I. No. 690) has been the 

 highest yielding variety, with the Manchuria (Minn. No. 6, C. I 

 No. 638) second. In the 6-rowed naked group, the Black Hull-less 

 (C. I. No, 1106) has yielded quite well. There has been less than

Fig. 12. — Diagram showing the average yields of the five leading varieties of spring barley on the Cheyenne 

 Experiment Farm, 1913 to 1915, inclusive. 



1 bushel difference in the yields of the White Smyrna and the Coast, 

 the two leading varieties. The Hannchen has also yielded weU, 

 since the yields here presented are averages from several check 

 plats of this variety in 1913 and 1914. 



KATE-OF-SEEDING EXPERIMENT. 



A rate-of-seeding experiment with the Svanhals barley has been 

 conducted at the Cheyenne Experiment Farm during the 3-year 

 period, 1913 to 1915, inclusive. In 1913, plats were sown at the 

 rates of 2, 3, 4, and 5 pecks per acre. In 1914 and 1915 sowings 

 were made at the rates of 2, 3, 4, 5, 6, and 7 pecks. The annual and 

 average yields obtained in the rate-of-seeding tests are shown in 

 Table XXII.
