الملخص EN

Water is a specific resource for agricultural production, and this is why the water problem tops the priorities of agricultural policy makers in Egypt, as it depends entirely on its share of the Nile River water, which amounts to about 55.5 billion cubic meters annually, which represents about 73.5% of the state's water resource inputs.

In the decrease in the quantities of irrigation water available for use in the Dakahlia Governorate, as a result of waste and wasteful use of those water resources, especially in agriculture, This study mainly aims to estimate the technical, productive and economic efficiency of the modern irrigation systems used in the irrigation of potato and tomato crops in the new lands.

Ton / acre under the three surface irrigation systems, sprinkler and drip respectively, and it amounted to about 14.48, 18.75 and 22.43 tons / acre under the three irrigation systems respectively for summer tomato crop.The study recommends expanding the use of modern irrigation methods and systems represented in sprinkler and drip irrigation in new lands, as well as generalizing them at the level of Dakahlia and the Republic, and the necessity of rationalizing the use of irrigation water in a way that does not exceed the water limits for both the summer tomato and winter potato crops.
