Calculate Internal Efficiency (IE)
Description
The fraction of plant tissue N that is contained in the yield component. Calculate IE using the formula: IE = YieldNF / PlantNf
Usage
IE(YieldNF, PlantNf)
Arguments
YieldNF |
A numeric vector for yield N in fertilized Conditions. |
PlantNf |
A numeric vector of non-fertilized control yield values. |
Value
The calculated IE value.
