12 TEN YEARS' EXPERIENCE WITH THE SWEDISH SELECT OAT. 



The figures for the Swedish Select and the Siberian varieties are 

 for the full 5-year period. The other varieties, except the Wisconsin 

 Wonder, were sown first in 1900, and the average yields are therefore 

 for 4 years only, while the Wisconsin Wonder was grown only in the 

 3 years from 1901 to 1903. The same varieties made the highest 

 yields for the 7-year period from 1899 to 1905, but in the following 

 order: D . , 



Bushels. 



Swedish Select 58. l 



Wisconsin Wonder 56. 1 



Big Four 55. 3 



Siberian 54. 9 



Early Gothland 53. 5 



Lincoln 53. 3 



Silver Mine 50. 9 



The Swedish Select is the only one of the seven varieties that was 

 grown every year of this period. The Siberian, Early Gothland, and 

 Silver Mine were grown for 6 years, and the Wisconsin Wonder, Big 

 Four, and Lincoln for 5 years. The average yield per acre of the 

 Swedish Select oat for 7 years is 2 bushels greater than that of the 

 Wisconsin Wonder, standing next highest, though from fifteen to thirty- 

 five good varieties were compared during this time, while during 8 

 years it averaged 3.3 bushels per acre more than the Siberian, which 

 yielded next highest for that period. 



Such figures as the foregoing do not, however, give an accurate 

 idea of the yields, as all varieties are not always grown the same years. 

 By substituting Tobolsk for Lincoln we have seven kinds, some or all 

 of which have been grown every year of certain periods. For exam- 

 ple, the seven were grown each of the 6 years from 1901 to 1904, 1906, 

 and 1907, with average yields per acre as follows:

Early Gothland 42 - 5 



Big Four 4L6

Six of these seven varieties were each grown every year of the 



7-year period from 1900 to 1904, 1906, and 1907, and another series 



of six was grown every year of the 7-year period from 1901 to 1904 



and from 1906 to 1908, with yields as follows:
