Yield Results
Yield Per Acre
Total Field Yield
Financial Analysis
Formula used: Yield = Field Size × (Kernels per Ear × Ears × 1000) ÷ Kernels per Bushel
Sample calculation: 800 kernels/ear × 0 ears = 0 kernels per 1/1000 acre
Kernel size: Medium kernels (90,000 kernels per bushel)
Yield Performance Analysis
Example Calculation
Typical Corn Field Example
Sample data: 1/1000 acre plot
Kernels per ear: 800 kernels
Ears counted: 32 ears in sample
Field size: 40 acres
Kernel size: Medium (90,000 kernels/bushel)
Calculation Steps
1. Total kernels in sample: 800 × 32 = 25,600 kernels
2. Bushels per 1/1000 acre: 25,600 ÷ 90,000 = 0.284 bushels
3. Yield per acre: 0.284 × 1,000 = 284 bushels/acre
4. Total field yield: 284 × 40 = 11,360 bushels

Sampling Tips
Take samples from multiple representative areas
Count kernels in a full row, then multiply by rows
Sample after corn has reached physiological maturity
Use consistent sampling methodology across the field
Consider weather and growing conditions when interpreting results
Understanding Corn Yield Estimation
How the Calculator Works
This corn yield calculator estimates your harvest based on a small sample area (1/1000 acre) and extrapolates the results to your entire field. By counting kernels per ear and the number of ears in the sample, we can predict the total yield.
Why Sample 1/1000 Acre?
- •Provides statistically significant representation
- •Manageable size for accurate counting
- •Industry standard for yield estimation
- •Easy to scale up to full field calculations
Yield Formula Explanation
Yield = Field Size × (KPE × Ears × 1000) ÷ Kernels per Bushel
- KPE: Kernels per ear in your sample
- Ears: Number of ears counted in 1/1000 acre
- 1000: Multiplier to scale from 1/1000 to 1 acre
- Kernels per Bushel: Depends on kernel size
Factors Affecting Yield
- Weather: Rainfall, temperature, and growing degree days
- Soil quality: Nutrient content and soil health
- Planting date: Optimal timing for your region
- Plant population: Seeds planted per acre
- Variety: Genetic potential of corn hybrid
