Corn Yield Equation:
From: | To: |
The corn yield estimation by kernel count provides a method to estimate potential yield before harvest by counting plants and average kernels per ear in a representative area of the field.
The calculator uses the corn yield equation:
Where:
Explanation: The equation estimates bushels per acre by multiplying plant population by average kernels per ear, then dividing by the standard number of kernels per bushel.
Details: Early yield estimation helps farmers make informed decisions about harvest timing, storage needs, and marketing strategies.
Tips: Count plants in a 1/1000 acre area (typically 17.4 ft of row in 30-inch rows). Sample multiple ears for accurate kernel counts. All values must be positive numbers.
Q1: How accurate is this method?
A: With proper sampling (multiple locations and ears), accuracy is typically within 10-15% of actual yield.
Q2: What's the standard kernel count per bushel?
A: The standard is 90,000 kernels per bushel, though this can vary slightly by hybrid and kernel size.
Q3: When should I do yield checks?
A: Best done at physiological maturity (black layer formation) when kernel counts are finalized.
Q4: How many sample areas should I check?
A: For reliable estimates, sample at least 5 areas per field, more in variable fields.
Q5: Does this account for harvest losses?
A: No, this estimates biological yield. Actual harvested yield will be 5-15% lower due to harvest losses.
