Relative Yield of Varieties of Corn at Auburn 



In the following table the average yield of all vari- 

 eties for each year is taken as a standard for that year, 

 or as 100 percent. The yields of each variety are then 

 expressed in terms of percentage. The following table 

 shows the average percentage yield of each variety 

 for all the years during which it was tested:

 ent years except in 1909 when two of the improved strains ex- 

 celled the yields of the parent unimproved variety. 



**The above note applies to Unimproved Henry Grady and 

 its selected strains.
