How to Compute Capacity | 
of Cribs and Bins 
Square or Rectangular Cribs—Mul- | 
tiply the length by the width by the | 
depth of grain (all in feet). Multiply | 
this sum by 2 and divide by 5. The | 
result is the number bushels ear corn | 
at 70 lbs. per bu. Correct for shelling | 
percentage and moisture as directed | 
on preceding pages. 
Round Cribs—Multiply the diame- | 
ter (distance across center) by the | 
Multivly this sum by the | 
depth (all in feet). Multiply the sum | 
The result is bushels at 70 | 
Ibs. per bu. Correct for moisture and | 
diameter.

Piles of Corn—When heaped in form | 
Square the depth and | 
square the inches of slant height (ie. | 
multiply each by itself). Subtract the | 
lesser of these amounts from the} 
Multiply the difference ob- | 
tained by the depth in inches. Multi- | 
vly this product by .0024. The result | 
is the bushels shelled corn at 70 Ibs. |

this result by two. 
The above formulas give bushels of | 
70 lb. basis ear corn. For shelled corn | 
capacities in bushels double number | 
bushels ear corn and correct for mois- | 
ture content. 

How to Compute Yields of 
Corn in the Field 
Hill Planted Corn 
Pick and weigh all corn from 25 
consecutive hills in four representa- 
tive locations. Multiply the weight 
of corn from these 100 hills by the 
correct factor in table below. Result 
is yield in bushels per acre, on 70-lb. 
per bu. basis, uncorrected for moisture 
and shelling percentage (see follow- 
ing pages).

Drilled Corn 
Take the weight of corn husked from 
the distance shown in the table below. 
Multiply by 100 and divide by 70. The 
result is yield in bushels per acre, 70
