Optimization of dry biomass partitioning coefficients.

Usage

OpMaizeGro(phen = 1, iCoef = NULL, cTT, WetDat, data, plant.day = NULL, emerge.day = NULL, harvest.day = NULL, plant.density = 7, timestep = 1, lat = 40, canopyControl = list(), MaizeSeneControl = list(), photoControl = list(), MaizePhenoControl = list(), MaizeCAllocControl = list(), laiControl = list(), soilControl = list(), MaizeNitroControl = list(), centuryControl = list(), op.method = c("optim", "nlminb"), verbose = FALSE, ...)
