Abstract

Fixed-furrow irrigation (FFI14 with 14 days interval and FFI7 with seven day interval) were used to investigate the impacts of deficit irrigation on maize yield, maize-water relations and economic return for the Middle Nile Delta soils compared with conventional every furrow irrigation method with 14 days interval (EFI). The results indicated that grain yield was increased with FFI7, whereas it tended to decrease under FFI14, in comparison to EFI. The water applied is reduced with FFI7 and FFI14 when compared to EFI. The crop water use decreased under the FFI7 and FFI14 techniques as compared to EFI. The FFI7 scheme exhibited improved crop water use efficiency values, compared to EFI. The results indicated also that FFI7 treatment does not only increase grain yield, benefit-cost ratio and net return, but also save irrigation water.
