Title: HYDRAULIC PERFORMANCE OF AUTOMATED DRIP IRRIGATION SYSTEM UNDER SHAMBAT OPEN FIELD CONDITION
Author: Mohamed Ibrahim Abd Algabar, Mohamed
Abstract: This study was conducted in the Demonstration Farm of the Faculty of Agriculture, University of Khartoum during two consecutive seasons (2006/2007 and 2007/2008). An automated drip irrigation system was installed where an electronic timer together with electric solenoid valves were used to control the irrigation duration and interval. The study also included determining the effect of three different irrigation intervals on the growth of Damas ornamental trees. The study was executed using a randomized completed block design. The study on the hydraulic characteristic of drip irrigation system gave 23.8 l/h for average emitters discharge, 95.3% uniformity distribution, and 97.4% coefficient of uniformity, 93.3% emission uniformity and 1.05 scheduling uniformity. The results showed that the agronomic parameters of Damas were significantly (P =603; 0.05) affected by irrigation intervals. The group of Damas trees which were irrigated twice a day gave the best results with respect to plant height, number of leaves per plant, number of branches per plant, canopy diameter and stem diameter followed by plants, which were irrigated daily then those which were irrigated day after day
