The Regional Adaptation of Corn in Nebraska 
braska’s corn crop are heat, moisture, and soil fertility. Ne- 
braska’s great regional diversity of crop growing conditions 
affords a splendid opportunity for this study. The environ- 
mental and corn types surveys follow.

THE ENVIRONMENTAL SURVEY OF NEBRASKA’S CORN 
GROWING CONDITIONS 
Climate and soil are the chief variable growth factors in 
the State, where corn is grown, and variations within these ap- 
pear to be almost wholly responsible for the widely differing corn 
types found in various parts of the State. 
Climatic differences may be readily analyzed, and their 
collective effects on corn are very apparent. The effects of re- 
gional soil differences are far less pronounced. In general, thru- 
out the State where corn is grown, the land is fertile and capable 
of producing large crops. Greater local than regional differences
