Abstract

FAO-Penman method is reliable to predict the reference evapotranspiration, ETo under climatic conditions in Nile-Delta region, Egypt. This method is developed by comparing and evaluating selected estimation methods (PA0-Penman, FAO-Radiation, and FAO-Blaney-Criddle) with results obtained from field data (Class A Pan). Monthly values of Eto are estimated by each of the selected methods using climatic data collected from six observation stations (records of 1995) within the area under study. The irrigation/crop water requirements, ETC, for main crops growth in this region are then computed. Considering FAO-Pengan formula, an empirical equation is developed to predict ETc for each crop under climatic data. The predicted seasonal Etc are generally comparable with those adopted by Ministry of Public Works and Water Resources, (WPWWR) with an average relative error of 157 for most of the main crops.
