Abstract

Accurate calculation of irrigation water requirement, affects directly the crop production, water use efficiency (WUE), and energy use efficiency (EUE).  Two methods for calculating irrigation water requirement were compared under two types of emitters (R and T). The first method was based on the Moisture Allowed Depletion (MAD) while the second based on meteorological data (Met). Three percentages of MAD, 50, 60, and 70% of available water were experimented. Experiment has taken place under clay soil in the north of Nile Delta (Sakha region). Results showed that the treatments based on the meteorological data have consumed less amounts of water. In addition, Met treatments recorded the greatest values of water application efficiency (WAE). WAE has been significantly affected by the method of water requirements calculation while type of emitter did not significantly affect the WAE. The meteorological based method gave the greatest values of crop production, WUE, and energy use efficiency (EUE) for both emitters. There was a decrease in the production for the 70% MAD as a result for water stress. This production decrease caused a decrease in WUE and EUE. It was recommended to use the meteorological based method for optimized amount of applied water that will keep the crop production and increase WUE, EUE, and WAE.
