FIFTT ANNUAL YEAR BOOK — PART I.

The presence of these nubbins greatly reduces the annual yield of corn. 

 Through extreme earliness, or extreme lateness, or owing to lack of vitality 

 they never produce good ears. They receive the same care and cultivation 

 as the good ears and in return yield very little. By carefully selecting only 

 vigorous seed ears we can greatly reduce this loss. In connection with this, 

 study "The Product of a Single Hill," Fig. 14. 



Figure 10, Ears Nos. 5 and 2 illustrate ears of corn with good kernels of 

 medium depth. Ears Nos. 1 and 3 illustrate very shallow kernels, and if the 

 kernels from these four ears are mixed it is impossible to plant them evenly. 



Ear No. 4 shows space between the kernels at the cob which indicates 

 weak vitality, low percentage of corn to cob and low feeding value, the 

 valuable portion of the kernel not being filled out. When examined exter- 

 nally these ears all appeared equally good. This shows the importance of 

 removing several kernels when selecting seed corn.
