 Reference Evapotranspiration (ET0) is a critical component for developing meaningful irrigation schedule for important crops. As a result, accurate forecasting of future ET0 is critical for better management of restricted water resources in many regions of the world. The potential of a Hierarchical Fuzzy System (HFS) optimised using the Particle Swarm Optimization (PSO) method (PSO-HFS) to forecast daily ET0 is investigated in this work. The climatic variables and predicted ET0 were used as inputs and outputs for the PSOHFS model, respectively. The climatic variables gathered from two meteorological stations in Bangladesh, Gazipur Sadar and Ishurdi, were used to compute ET0 values using the FAO 56 PM technique. We evaluated the PSO- HFS model's prediction accuracy to that of the FIS, M5 Model Tree, and Regression Tree (RT) models. The effectiveness of the PSO-HFS FIS, M5 Model Tree, and RT in calculating daily ET0 was assessed using a number of statistical performance assessment metrics. The idea of Shannon's Entropy, which takes into consideration a number of performance assessment indices, was used to rank the models. The PSO-HFS model outperformed the treebased models, according to the results. The overall findings suggest that the PSO-HFS model might be used to reliably and efficiently simulate ET0 values
