Abstract
The exact estimation of the amount of water consumed by a plant through the calculation of evaporation and perspiration is a method of improving agricultural water management. Most of the calculations of evaporation and perspiration are done according to the data collected from the reference stations, but aerological data are mostly taken from non reference stations. To consult these kinds of data for the calculation of evaporation and perspiration in development planning, may cause great mistakes. To overcome these mistakes, data should be corrected. In this research the effect of temperature data correction is investigated and the effect of correction is compared with the results from weighting lysimeter. Temperature correction did not affect the Hargreavs - Samani method, but Fao 24, priestly-tylore and Jensen- Haisepass were the most appropriate methods for the calculations of evaporation and perspiration.

Key words: evaporation and perspiration, reference stations, non-reference station.
