NUtE: Calculate N Utilization Efficiency (NUtE)

In NUETON: Nitrogen Use Efficiency Toolkit on Numerics

Calculate N Utilization Efficiency (NUtE)

Description

The contribution of fertilizer N from the plant tissues towards the yield component. Similar to PE, but does not account for background N. Calculate NUtE using the formula: NUtE = Yield / PlantN

Usage

NUtE(Yield, PlantN)

Arguments

Yield	A numeric vector of yield values.
PlantN	A numeric value for plant tissue N.

Value

The calculated NUtE value.
