Where there are differences in soils, often it is wise to 
use several varieties to match the different soil types. 
DeKalb research has built varieties for almost every 
kind of soil. 
Farmers interested in feeding will find almost any 
degree of dent in DeKalb varieties — from round and 
shiny to deep and rough and texture from hard and 
flinty to the very soft types. 
For the silo you can have your choice of extra-leafy 
corn or high grain content. Some DeKalb varieties 
have both large leaf area and high grain yield. Uni¬ 
form in height and maturity 
If you were to visit DeKalb's remarkable corn breeding 
nurseries to walk up and down the alleyways between 
neat, uniform plots of precious foundation stock „. and 
to travel through the States of DeKalb Country to all of 
DeKalb's 39 experimental corn farms and 2700 proving 
grounds .. . no doubt you would be amazed at the vast¬ 
ness of this tremendous program of far-reaching corn 
research. Amazed and confused too, by the maze of in¬ 
tricate details involved in DeKalb's "search through 
research" for superior hybrid corn. DeKalb feels justified 
in spending unstintingly for research because they know 
that only through research, can present hybrids be im¬ 
proved and still more efficient varieties created. And so 
research goes on and on—year after year—under the 
ever-watchful eye of DeKalb's corn breeding specialists. 
Thus a large part of the price on every bushel of DeKalb 
seed sold is passed on to research as an investment for 
better corn hybrids of the future ...
