#' Calculate NUEyield
#' @description
#' The contribution of N supplied from the soil that is allocated to the yield N;
#' also often referred to as simply NUE.
#' Calculate NUEyield using the formula: NUEyield = NUpE * NUtE
#' @param NUpE N Uptake Efficiency
#' @param NUtE N Utilization Efficiency
#' @returns The calculated NUEyield value.
#' @examples
#' NUpE <- 33.63571
#' NUtE <- 1.009715
#' NUEyield(NUpE, NUtE)
