Corn Yield Calculator
Estimate corn yield per acre using ear counts and kernel measurements.
Field Measurements
How It Works
Kernels per Ear = Rows × Kernels per Row
Yield (bu/ac) = (Ears × Kernels per Ear) ÷ 90,000
90,000 is a standard kernel weight conversion factor.
FAQ
Why divide by 90,000?
This is a commonly used factor that estimates how many kernels make up one bushel.
When should I use this calculator?
Use it during late grain fill to estimate yield before harvest.
Is this exact?
No. Actual yield depends on final kernel weight and harvest moisture.
About Corn Yield Estimation
Corn yield estimation allows producers to forecast production before harvest. By counting ears and kernels, farmers can quickly approximate expected bushels per acre.
Kernel weight varies by hybrid, weather, and management practices. The 90,000 factor assumes average kernel weight under normal conditions.
Yield estimation helps guide marketing decisions, storage planning, and crop insurance documentation.
