Corn Yield Formula:
From: | To: |
The corn yield calculation estimates the number of bushels per acre based on plant population and kernel count. This method provides a quick field estimate of potential yield.
The calculator uses the corn yield formula:
Where:
Explanation: The equation accounts for plant population and average kernel count to estimate total yield in bushels per acre.
Details: Early yield estimation helps farmers make harvest and marketing decisions, assess hybrid performance, and evaluate field management practices.
Tips: Count plants in a representative 1/1000 acre area (for 30" rows, this is 17'5" of row). Sample multiple ears for kernel count. All values must be positive numbers.
Q1: How accurate is this yield estimate?
A: This provides a rough estimate. Actual yield may vary ±20% due to kernel weight variations, harvest losses, and other factors.
Q2: What's a good sample size for kernel count?
A: Sample at least 10 representative ears from different areas of the field for reliable average.
Q3: When should I do yield checks?
A: Best done at dent stage (R5) when kernel number is finalized but before significant drydown.
Q4: Does this account for test weight?
A: No, this assumes standard 56 lb/bushel test weight. Higher test weight corn will yield more pounds per bushel.
Q5: How do I measure 1/1000 acre?
A: For 30" rows: 17'5" of row. For other row spacings: divide 43,560 by (row spacing in inches/12) then divide by 1000.
