Description
Return harvest/area for each plot and secondYield-firstYield.
Extension-training comparisons depend on score ranges, credit weights, unit factors, plot support and cost bases. A normalized difference or area-scaled harvest describes supplied records rather than proving learning, causal adoption or an agronomic effect. Caller-chosen factors need separate justification.
Return harvest/area for each plot and secondYield-firstYield.
When to use this tool
Use Extension Demo Plot Yield Comparison Term when checking the stated training, credit, demonstration-plot, unit or cost convention.
How to use the tool and how it works
- Enter firstHarvest, firstArea, secondHarvest, secondArea. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read firstYield, secondYield, gap. Use the output convention below.
Require positive plot areas and nonnegative harvests. Return harvest/area for each plot and secondYield-firstYield.1

| secondHarvest | Second Harvest | Required. Finite number; minimum 0. |
| secondArea | Second Area | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| firstYield | First Yield | Required. Finite number. |
| secondYield | Second Yield | Required. Finite number. |
| gap | Gap | Required. Finite number. |

}Limitations and assumptions
- Use compatible harvest and moisture bases; a two-plot comparison alone does not show causal treatment effects or statistical significance.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified representative observations and appropriate complete educational, statistical or budget analysis for substantive training, agricultural or funding decisions.
