Biomass (a–e) and yield (f–j) ratios of wheat under elevated carbon-dioxide concentration [eCO2] for APSIM, CropSyst, DSSAT, EPIC, and STICS at three Pacific Northwest sites. Three coloured lines represents sites at Pacific Northwest with ± standard errors and each box represents Model outputs for Biomass and Yield. Means are averaged over three replicates.
