sci.crop-yield-gap-analysis Calculator
Calculates the yield gap (YG = potential yield − actual yield) and yield gap closure ratio as a percentage of potential. Global average yield gap closure: 51% for maize, 50% for wheat, 56% for rice — irrigation, fertiliser, and improved varieties together account for most of the attainable yield.

Results
total yield gap (t/ha)
The combined total across all inputs and components.
resource gap (water/climate limit)
The value at the specified point or condition.
management gap (exploitable)
Sample size or count used in the calculation.
yield potential achieved (%)
Sample size or count used in the calculation.
current profit ($/ha)
Electric charge flow rate (A). Governs wire sizing — too much current causes dangerous heating. Fuses protect circuits from overcurrent.
profit at 80% potential
Revenue minus all costs -- the net gain from the activity.
