Estimate corn yield in bushels per acre from ear count, rows per ear and kernels per row, using the standard yield-component method.

How to use this tool
Count harvestable ears in a known area and scale to per acre.
Husk sample ears, count rows around and kernels along one row.
Use averages from several spots across the field.
Convert to kg/ha or tonnes/ha for comparison.
Formula & worked example
30,000 ears per acre × 16 rows × 35 kernels gives about 186.67 bushels per acre.
Limitations — read this before you rely on it
Estimate only. It assumes uniform ears, full grain fill and the standard 90,000 kernels per bushel; it does not adjust for moisture or harvest loss.
Frequently asked questions
A bushel of corn holds roughly 90,000 kernels, so total kernels divided by 90,000 gives bushels.
Count ears in a measured row length, then scale by row spacing to one acre.
It estimates biological yield before harvest loss, moisture adjustment and field variability.
Yes. Market bushels are adjusted to 15.5% moisture; wetter grain weighs more but shells down.
Good for planning when averaged over many samples; a single spot can mislead badly.
