During the years 1916 and 1917, deep-grained rough ears and 
shallow-grained smooth ears were selected in bulk and compared 
for yield with the original Hogue’s Yellow Dent corn. As an 
average for the two years, the grain yields were respectively 
64.0, 69.6, and 64.5 bushels per acre for the three lots. The 
smooth ears surpassed the original corn 5.1 bushels per acre and 
the rough corn 5.6 bushels, and showed a tendency for greater 
earliness. The results are given in Table 50.

corn. 1916 and 1917.

Further data from this Station, reported in part by Mont- 
gomery in 1909 in Bulletin 112, regarding the relation of ear 
type and yield are given in Table 51. During the six years 
1905-1910, long, smooth ears of Keid's Yellow Dent were con-
