Title: Assembling and Performance Evaluation of Centre Pivot Irrigation System New Hamdab Irrigation ProjectNorthern State, Sudan
Author: Elhassan, Zuhair Abdalmalik
Abstract: This study was conducted at new Hamdab agricultural project, one of the newly established resettlement projects associated with the implementation of Merowi Dam. The project lies on the western bank of the River Nile in the Northern state about 300 km north of Omdurman. Following the innovation technologies in the irrigation systems world wide, this study has come to make a comparison between modern irrigation systems and traditional ones in aspects of operation costs, irrigation water requirement and expected yield. The study comprised an updated comprehensive survey on the centre pivot systems introduced in Sudan; then assembling five Zimmatic centre pivot systems on predetermined locations on the sandy area (high terrace) of new Hamdab project. The systems were then evaluated for hydraulic performance namely, uniformity coefficient (Cu), distribution uniformity (Du) and application efficiency (Ea). The centre pivot system was then compared with surface irrigated field plots (pilot farm) while considering the traditional method (tenant field) as a control and wheat as an indicator crop. The centre pivot system wwhen run at two speeds (40% and 100%) respectively gave the following results: 1- Uniformity coefficient (Cu) 75% and 85%. 2- Distribution uniformity (Du) 60% and 76%. 3- Application efficiency (Ea) 53% and 47%. . With respect to wheat growth parameters and yield attributes, the centre pivot irrigation system showed highly significant difference over the pilot farm and the tenant farms, the average productivities of wheat per feddan were respectively: 1532 kg, 464kg, 159 kg for center pivot, pilot farm and tenant farm. On the other hand records of water consumed per feddan per season were 5344 m3 for the centre pivot and 9306 m3 for either one of pilot farm and tenant’s farm. The study clearly shows that center pivot irrigation system has gave prospects particularly in the high terrace soils in north Sudan.
