3.5 Mapping carbon and nitrogen content of aboveground plant and grain at maturity
In view of the better performance of DArs, the maps of updated W above, yield,N above and N grain at the experimental site at maturity were generated (Fig. 9) by assimilating the in-season crop growth simulation and leaf traits’ prediction (Fig. 5). Differences in the indirectly updated biomass and N content of aboveground plant and grain caused by the different N input were observed between the experimental plots. The variances of those updated simulations within each experimental plot were also shown in their corresponding maps (Fig. 9), in line with the existing variances in the maps of predicted leaf traits (Fig. 5).
