In NUETON: Nitrogen Use Efficiency Toolkit on Numerics
NHI R Documentation
Calculate N Harvest Index (NHI)
Description
The percent of plant tissue N that is contained in the yield component.
Calculate NHI using the formula: NHI = YieldF / PlantNf
Usage
NHI(YieldF, PlantNf)
Arguments
YieldF
A numeric vector of final yield values.
PlantNf
A numeric value for plant tissue N.
Value
The calculated NHI value.
