Fig. 5. Comparison of the additivecompensative and multiplicativecompensative models with the dominant factor model for the melon data from Shani and Dudley (2001). The additive and multiplicative model results were taken from Dudley and Shani (2003). Experimental (symbols) and computed (solid lines, assuming dominant factor model; dashed lines, assuming additive compensation; dotted lines, assuming multiplicative compensation) results. The term I is irrigation quantity, E0 is potential evapotranspiration, Y is yield, Ym is maximum yield, and EC is electrical conductivity.
