The research aimed to study the impact of developing the flood irrigation system to the developer on the productive and economic efficiency of the wheat crop in Assiut Governorate. The results of the availability criterion indicate that wheat production reached a minimum of about 7.17 million tons in 2010, and a maximum of about 16.79 million tons in 2018. According to the capacity standard, the minimum level of self-sufficiency in wheat was about 41% in 2010, and the maximum was about 67% in 2009, and according to the sustainability standard, the number of imports reached its minimum in 2009, about 4.06 million tons, and its maximum in 2021 reached about 10.05 million tons. Regarding the sustainability criterion, the wheat gap reached a minimum of about 4.06 million tons in 2008 and 2009 and a maximum of about 10.05 million tons in 2021. The results of production efficiency also showed that improved irrigation contributes to saving about 90.9 m3 in wheat cultivation, and it also achieves a surplus in both acreage productivity. Nitrogen and phosphate fertilizers and pesticides used in the amount of 0.5 tons/F, 22.5 nitrogen units, 13.7 phosphate units, 0.86 kg/F pesticides, respectively. According to economic efficiency, the surplus net return, cost savings, and net return from the water unit was estimated at about 5029 g/F, 7%., 3 c/m3, respectively, by following the developed irrigation methods. The research recommends increasing reliance on developed irrigation methods in Assiut Governorate, reducing tax burdens for crops that consume less water, providing the necessary funding to shift towards developed irrigation methods, and rationalizing the use of water for various uses.
