heads, or weak straw. In some seasons the durum varieties have 
outyielded the common varieties, and in others the reverse has been 
true. 
Table 16 shows the annual and average yields of 18 varieties of 
spring wheat grown on both fallow and cornland during the 6-year 
period from 1917 to 1922, inclusive. Figure 14 presents graphically 
the yields of the most important spring-wheat varieties grown in all

Fic. 14.—Average acre yields of five varieties of spring wheat at the Akron Field Station during the 15- 
year period, 1908-1922, inclusive 
years. Agronomic data on 11 varieties grown on fallow and on corn- 
land from 1917 to 1922 are presented in Table 17. From the results 
obtained with winter and spring wheat, it is concluded that seeding of 
spring wheat at Akron is not to be generally recommended. Even 
when sown as late as the latter part of October, winter wheat is 
apparently safer than spring wheat.
