Crop Simulation Maps and Figures Figure 28 Scatter plot of the actual (historically measured) and modeled yield for Tomato at Shendi research station. The x-axis represents observed yields (Yield_obs), and the y-axis represents modelled yields (Yield_mod). The green line represents the ideal 1:1 relationship where modelled yields perfectly match observed yields
Crop Simulation Maps and Figures Figure 27 a) Scatter plot of the actual (historically measured) and modeled yield for Onion at Shendi research station. The x-axis represents observed yields (Yield_obs), and the y-axis represents modelled yields (Yield_mod). The green line represents the ideal 1:1 relationship where modelled yields perfectly match observed yields
Crop Simulation Maps and Figures Figure 26 a) Time series of modeled Tomato yields at Shendi for the historical period and future period (2021-2080) under the two scenarios RCP 4.5 and RCP 8.5. (b) time series of downscaled climate variables, for the same periods and the same scenarios. (Top) rainfall in mm & (bottom) Reference Evapotranspiration (ETo mm/day). Climate variables are averaged over the growing season. Red, green and blue colors depict the historical, RCP4.5 and RCP8.5 periods, respectively
