COST PER UNIT ON FARMS HAVING DIFFERENT YIELDS 
The cost records of the seven crops are arranged in Tables 53 to 
59 in groups according to yield per acre. These tables show the 
variation in the yield of each crop; the number of records falling within 
each yield group; and the average cost per unit on the farms having 
different yields. 
Wheat ranged in yield from as low as 16 bushels per acre to as 
much as 93 bushels; alfalfa hay (three cuttings) from 2.2 to 7 tons; 
potatoes from 42 to 260 hundredweight; beans from 106 to 2,455 
pounds; sugar beets from 1.5 to 22.5 tons; red-clover seed from 55 
to 720 pounds; and alsike-clover seed from 141 to 625 pounds. 
Low yields go hand in hand with high cost per unit of product and 
high yields with low cost per unit. The exceptions are due to the 
fact that yield per acre is not always the dominant factor in determin-
