We established a Mamdani fuzzy logic model to determine the effect of wastewater evapotranspiration on citrus cultivation. The model uses most influential variables of soil and leaves samples. Since the number of the input variables to the model is large, these variables were classified into five categories as follows: (i) soil macro-element concentration, (ii) soil essential elements concentration, (iii) soil electrochemical properties, (iv) leaves macro-elements concentration, and (v) leaves essential elements concentration. For simplification, the model was divided into seven submodels and one main model. The output of the main model considered the outputs of all submodels to the final decision. The model applied to a citrus orchard suggested the optimal wastewater irrigation rate at 125% of crop evapotranspiration. (AU)
