We would probably not be far wrong in estimating the average 
water requirement of corn in eastern Nebraska at 9 inches of 
rainfall, which amount fluctuates greatly, of course, in different 
years. The average annual precipitation in eastern Nebraska is 
approximately 28 inches, two-thirds of which is lost in ways other 
than by transpiration from the corn crop.
