Abstract: In this study daily evaporation rate from class A pan and reduced pan installed inside the glasshouse with a class A pan installed outside were compared. The results showed that the mean weekly ET0 value estimated by the class A pan installed outside and inside the glasshouse were 27.6 mm and 17.6 mm respectively, and 20.3 mm for the reduced pan. The ET0 in the glasshouse was found to be 64% of outdoor ET0. With regard to the comparisons between the weekly ET0 values estimated by the class A pan and reduced pan, both inside the glasshouse, coefficient of correlation was obtained 0.95 for the reduced pan method and with comparing between the weekly ET0 values estimated by the class A pan outside the glasshouse and those estimated by the different methods inside, coefficient of correlation was obtained 0.71 for the class A pan and 0.68 by the reduced pan.
