The Corn Yield formula estimates the amount of corn produced by a field.  This is based on the acres (a) in the field, and the results of a thousandth acre sample with (e) ears of corn, (r) rows of kernels in the head, (k) kernels per row and (S) size kernels.  The result is the approximate number of bushels of corn (yield) for the field.

Method to count the kernels in an ear of corn.

Note: the rounded ends of the head are not considered since the combine will often not collect those kernels.

This formula uses the default of average sized kernels of corn in a bushel.  The ratios are as follows:

• small - small kernels require 120,000 kernels in a bushel
• medium - medium (average) sized kernels require 90,000 kernels in a bushel.
• large - large kernels only require 80,000 kernels for a bushel.
