Abstract

The objective of this research work is to evaluate the performance of surge and continuous furrow irrigation based on field experiments. The experiment took place on a private farm located in El- Santa district, Gharbeiah Governorate, middle of the Nile Delta, Egypt, cultivated with corn, having a clay-loam textured soil. In this study, two of main design and management variables (unit flow rate, Q0; and cutoff time, tco) are selected such that the corresponding performance indices (advance time, surface runoff, seasonal irrigation requirements, Qreq; application efficiency, Ea; water storage efficiency, Es; and distribution uniformity (CU) are measured and discussed. Surge flow with three numbers of surges (i.e. 2, 3 and 4 surges) were compared to continuous flow to opened long furrows of 120 m length without dikes, cultivated with corn (Zea Maize) during growing seasons of 2016 and 2017. Main results cleared out that the water applied during surge treatments advanced faster compared with continuous one. On the average, water saving of 18 to 30% was observed in surge-irrigated furrows under different rates of discharge and on-off cycles. Under surge technique performance indices such as, water needed per each irrigation, seasonal needs of irrigation water, surface run off, application efficiency, storage efficiency and distribution uniformity were enhanced. The surge mode of irrigation is convincingly better compared with continuous irrigation.
