 Summary:
 Irrigation systems represent a direct measure which can solve the needs for quality water in agriculture. In order to successfully design an irrigation system, it is necessary to analyze the current plant needs for water, i.e. evapotranspiration, as well as the future needs. In this paper, the FAO-56 Penman-Monteith method was used to determine the reference evapotranspiration (ET0) from 9 meteorological stations in Serbia for the period 1980-2010. The obtained ET0 values were used for ET0 analysis and forecasting. Three smoothing techniques were used (moving average method, exponential smoothing and Holt-Winters forecasting model), and three statistical tests were applied for their comparison.
