Partial Factor Productivity (PFP)

Total yield per unit of nutrient applied, without deduction of control yield.

partial_factor_productivity(yield, nutrient_applied, verbose = TRUE)

Arguments

yield

Numeric vector. Crop yield (kg/ha).

nutrient_applied

Numeric vector. Nutrient applied (kg/ha).

verbose

Logical. If TRUE, prints informational messages. Default TRUE.

Value

Numeric vector. Partial factor productivity (kg yield per kg nutrient applied).

Details

$$PFP = \frac{Y}{F}$$

Examples

partial_factor_productivity(yield = 4500, nutrient_applied = 120)
#> PFP computed (kg/kg).
#> [1] 37.5
