The Nile River is the main source of water in Egypt, through which Egypt obtains its annual share of 55.5 billion cubic meters. The agricultural sector is one of the most important economic sectors that uses water resources, as it consumes about 86.5% of Egypt's share of water. The research problem is the limited water resources with the increasing demand for them in agriculture, which requires a review of water use. The research aims to estimate the economic value of water in the production of the most important agricultural crops in Egypt, whose cultivated area exceeds 50 thousand acres annually during the period (2019-2022). Among the most important results, grain crops accounted for the largest share of the cultivated area, with an average of about 7.1 million acres during the study period. It was also found that sugarcane and cotton crops had the highest production costs per acre, with an average of about L.E. 22.2, 19.8 thousand, while garlic and onion crops achieved the highest net return, with an average of about L.E. 26, 25 thousand. The cost of irrigation also increased for each of the crops of sugar cane, rice, peanuts, and cotton, with an average of about 3023.5, 1659.8, 1561.8, and 1546.5 LE /ton, respectively, while the lowest cost of irrigation was for the crops of sunflower and sesame, with an average of about 749.3 and 746.5 LE/ton, respectively. The highest productivity per cubic meter of water was for the crops of perennial clover and sugar beet, with an average of about 11.9 and 7.3 kg. The highest economic value per unit of water was for the crops of garlic, cotton, perennial clover, and onions, with an average of about 16.67, 11.08, 9.6, and 9.32, LE/m3 respectively. The net water return also reached its maximum for the crops of garlic, peanuts, and sunflower, with an average of about 10.6, 7.76, and 6.15 LE /m3. Also that the most crops the water requirement for producing one ton of crops is lupine and sesame, with an average of about 12.8, 5.7 thousand m3/ton, respectively. Sunflower, sugar beet and lupine crops are less expensive in terms of production energy, with an average of about 51.7, 29.9 and 16.5 LE/ton, respectively. While sesame, onion and sorghum crops were less expensive in terms of irrigation energy, with an average of about 0.23, 0.22 and 0.21 LE /m3, respectively.
