    Think corn yield estimator is spot on but I have never seen an ear of corn with an odd number of rows as in your example. Always enjoy your articles very informative.

      Dear Charles,

      You likely won’t ever see an ear with an odd number of rows, because corn kernel rows develop as pairs as shown in the top photo.

      However, you must sample a lot more than one ear in order to obtain a reasonable yield estimate or any of the parameters needed to calculate it! Thus, the value in the yield estimate example noted above can be any number, including tenths, or even hundredths – although corn kernel row number typically ranges from 12-20. The bottom line is you need to sample a lot of ears to calculate a good estimate.

      Thanks for the question and hope your crop turns out well!

    When you go to the field and start pulling ears of corn and say there are 30 ears with 16 and 30 ears with 14 the average number will be an odd number.

      Yes, Landon.

      The average or mean for your example is 15.0.
