Impact of modernization surface irrigation on the different efficiencies of irrigating the maize crop

Field experiments for this research were conducted in the northern Nile Delta Kafr ElSheikh governorate. impact of modernization surface irrigation and its performance old lands through modernized Marwa traditional by replacing them with one methods (lined mesqa - buried pipes), was done estimating efficiencies water application rate increase crop productivity per unit most important summer crops (Maize) compared to system. The also includes a hydraulic study systems modernized, results can be summarized as follows average 82, 79 49 % pipes, lining earthen respectively. Also showed that values distribution efficiency pipe conventional 78, 75 72 It found value (FWUE) 1.52,1.36 0.99 kg
