How to Use the Corn Yield Calculator
- Enter Plants per Acre – Input the number of corn plants per acre (e.g., 32,000). Must be ≥ 0.
- Enter Ears per Plant – Typical value is 1.0. Adjust if needed (≥ 0).
- Enter Kernels per Ear – Average count per ear (e.g., 600). Must be ≥ 0.
- Enter Kernel Weight – Weight in pounds per 1,000 kernels (e.g., 0.3). Must be ≥ 0.
- Click "Calculate Yield" – The result shows estimated bushels per acre.
Formula: Yield = (Plants × Ears × Kernels × Kernel Weight) / (56 × 1000)
Note: All inputs must be greater than zero for a valid calculation. Use imperial units (pounds, acres). The result is in bushels per acre (1 bushel = 56 lbs).

Frequently Asked Questions
Yield (bu/acre) = (Plants per acre × Ears per plant × Kernels per ear × Kernel weight in lb per 1000 kernels) / (56 × 1000). The 56 represents pounds per bushel of corn.
Kernel weight varies by hybrid and environment, but a common value is about 0.3 lb per 1000 kernels (or 300 mg per kernel). Adjust based on your specific conditions.
This calculator is designed for grain corn yield estimation. For silage, yield is measured in tons per acre and uses different factors.
