Abstract

Rationalizing irrigation water and maximizing water use efficiency became the priority of irrigation planners and users under Egyptian conditions. Therefore, the aim of this study was to evaluate adjusted of self-compensating gated pipe for modified surface irrigation and to evaluate the pepper yield response and water use efficiency under three irrigation system (drip irrigation ,traditional gated pipe and modified gated pipe) and three water treatments (100, 75 and 50% of ETC) in old land conditions of Egypt. Hereby field experiments were carried out at the Experimental Farm of Faculty of Agriculture, Ain Shams University, Kalubia Governorate, which represents alluvial soils, for two successive growing seasons 2006 and 2007. Results revealed that. In laboratory experiments of self-compensating gated pipe out let average discharge from 29 L/min were obtained at pressure range of (2 – 9 kPa) with coefficients of variation less than 0.9%. Uniform discharge was obtained at modified gated pipe under pressure range of 45-90 cm. Corresponding field data were similar to laboratory data.  Regular uniform water flow from gates and regular uniform pressure head from each outlet was obtained along line at modified gated pipe under constant pressure.  Regular advance times approximately was obtained in modified gated pipe along furrows (0.6, 1.5, 2.6, 4, 5.4 and 6.7 min) at the first furrow and (0.7, 1.7, 3, 4.5, 6.2 and 7.7 min) in the end furrow at distance in meter (4, 8, 12, 16, 20, 24 m) respectively the same trend of recession time (min).Uniformity coefficient of distribution (CUD) along traditional and modified gated pipe was 82.7% and 96.3%, respectively. The highest total fresh pepper fruit yields (14319.5 kg/fed)with 75% of ETC under modified gated pipe, respectively. Water use efficiency treatment 50 % of ETC under drip irrigation was the superior in WUE (5.7 kg/m3).
