1. What is the Corn Yield Equation?

The corn yield equation estimates bushels per acre based on ear count and kernel count. It provides a quick field estimate of potential yield before harvest.

2. How Does the Calculator Work?

The calculator uses the corn yield equation:

Where:

• Ears per acre — Count of corn ears in one acre
• Kernels per ear — Average number of kernels per ear
• 90 — Standard number of kernels representing one bushel

Explanation: The equation converts ear and kernel counts into standard bushels per acre measurement.

3. Importance of Yield Calculation

Details: Early yield estimation helps farmers make harvest decisions, plan storage needs, and evaluate field performance.

4. Using the Calculator

Tips: Count ears in several representative areas of the field and calculate average ears per acre. Select typical ears to count kernels.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this method?
A: This provides a rough estimate. Actual yield may vary ±20% due to kernel weight differences and harvest losses.

Q2: How many ears should I count?
A: For best results, count ears in at least 5 representative 1/1000 acre areas (17.5 ft of row in 30" rows).

Q3: Why divide by 90 kernels?
A: Industry standard assumes 90,000 kernels per bushel, so 90 kernels represent 1/1000 of a bushel.

Q4: When should I do ear counts?
A: Best time is after pollination but before black layer formation, when kernel count is final but before drydown.

Q5: Does this work for all corn types?
A: The calculation works best for field corn. Sweet corn and popcorn may need adjustment factors.
