Abstract

Egypt has the majority of productivity of date palm fruit all over the world due to its nutritional, economic, and social importance to the Egyptians. Therefore, study aimed to apply new technique such as simulation models for improving distribution uniformity and the water application efficiency under different surface irrigation system techniques to raise in order to select the proper decisions of integrated water management. Field experiments had been carried out for two successive growing seasons of (2018-2019and 2019-2020) on date palm (Phoenix dactylifera) at the Experimental Farm in El-Dakhla distinct, New Valley Governorate, Egypt. Modified surface irrigation with gated pips was used with three irrigation water distribution techniques :( Two-side furrows, basin and one side furrow with loop). Results revealed that the statistical indicators of R2 (> 0.9), RMSE (nearest to 0) and E (> 0.9) between measured and simulated advance time and recession time. However, data analysis indicated high satisfactory to use the software under the Egyptian conditions for furrow irrigation. In addition, data revealed that the highest values of yield, water use efficiency and distribution uniformity were (12288kg/fed, 2.1 kg/m3 and 90%) for one side furrow with loop treatment comparing with two side furrow and basin (5440 kg/fed, 1.6 kg/m3 and 87%) and (5760 kg/fed, 0.8 kg/m3 and 68%).
