Estimated Corn Yield
Expert Tip
Perform counts at multiple representative spots in the field. This method is most accurate after the grain has reached the milk stage (R3) or later.
Calculation Methodology & Details
Formula
Calculates the yield based on the industry-standard University of Illinois formula. 1/1000th acre row length is: 43,560 / (Row Spacing / 12) / 1000.

How to Estimate Corn Yield
Follow this guide to execute a field estimate:
Determine Test Row Length
For 30-inch row spacing, measure exactly 17 feet, 5 inches.
Count Productive Ears
Count the number of harvestable ears inside that length.
Inspect Kernel Details
Pick 3 random ears, count kernel rows and average kernels per row.
