The research aimed to study the Egyptian water resources in terms of their sources and uses, and also aimed to identify the future water resources, and also targeted some technical indicators of the economic efficiency of using irrigation water in the developed irrigation system, and to identify the extent of significant differences in some of the average variables of the study crop, which is sugar cane, using Variance analysis method, and the economic impact of the developed irrigation projects on total costs, ransom productivity, the time of irrigation of acres, Total return, net return, and the cost of producing a ton for sugar cane crop was about  23374.44 pounds/acre, about 38.465 tons/acre about 4.50 hours/acre about 27693.12 pounds/acre, about 4318.70 pounds/acre, about 609.58 pounds/acre undeveloped irrigation system (traditional), while about 22760.07 pounds/acre, about 41.185 tons/acre, about 3.37 hours/acre, about 29655.54 pounds/acre about 6895.46 pounds/acre, about 554.28 pounds/acre irrigation system developed with its modular (pipes) PVC Lining with Concrete) corn respectively in Luxor Governorate, while in Aswan Governorate, the total cost of total costs, mortal productivity, Acre irrigation time, total return, net return, and the cost of producing a ton for sugar cane crop was about 23407.19 pounds/acre, about 42.10 tons/acre, about 4.86 hours/acre, about 30306.80 pounds/acre, about 6899.61 pounds/acre, about 556.15 pounds/acre, about undeveloped irrigation system (traditional), While it amounted to about 22941.79 pounds/acre, about 44.80 tons/acre, about 3.47 hours/acre, about 32257.18 pounds/acre, about 9315.40 pounds/acre, about 512.16 18 pounds/acre with the developed irrigation system Modular (P.V.C Pipes - Lining with Concrete) corn respectively.
