PE: Calculate Physiological Efficiency (PE)

In NUETON: Nitrogen Use Efficiency Toolkit on Numerics

Calculate Physiological Efficiency (PE)

Description

The contribution of fertilizer N from the plant tissues towards the yield component. Formula: PE = (YieldF - Yield0) / (PlantNf - PlantN0)

Usage

PE(YieldF, Yield0, PlantNf, PlantN0)

Arguments

YieldF	A numeric vector of final yield values.
Yield0	A numeric vector of non-fertilized control yield values.
PlantNf	A numeric vector of plant N at the end of the experiment.
PlantN0	A numeric vector of plant N at the beginning/control.

Value

A numeric vector of PE values.

Examples

YieldF <- c(12, 13, 14)
Yield0 <- c(10, 10, 10)
PlantNf <- c(3.5, 4.0, 4.2)
PlantN0 <- c(2.0, 2.0, 2.0)
PE(YieldF, Yield0, PlantNf, PlantN0)
