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.
