Making plans for storage and marketing of the corn crop often calls for estimating yields before the crop is harvested. Estimating corn yields is done by making this calculation: Number of Ears x Number of Rows x Kernel Row Length.

Row Width
Number of harvestable ears in of row
Number of kernel rows around per ear*
Number of kernels per row*
Number of kernels per ear*
* three ear average

Estimated Corn Yield   bushels/acre
