Fig. 3. Estimation of parameter (dark gray region) and total (light gray
region) uncertainty of GECROS with the nitrogen input of 0 kg
ha-1 (a-f) and 240 kg ha-1 (g-l) in
2019. Red lines represent the simulations from estimated mean values of
uncertain parameters. The solid circles with vertical bars denote the
means and standard deviations of measurements.W above, aboveground biomass;W grain, grain weight;W leaf, leaf weight;N above, aboveground N content;N grain, grain N content; andN leaf, leaf N content in the canopy.
