Title: Water and Crop Productivities of Alfalfa (Medicago sativa) Under Centre Pivot Irrigation Systems in Khartoum State
Author: Mohamed, Abdelmoneim Elamin; Adam, Adam Bush; Abd Aldaim, Amir Mustafa
Abstract: Experiments were conducted at three centre pivot irrigation projects in Khartoum State during the period from April 2011 to April 2013 with the objectives of determining water productivity and crop productivity of alfalfa (Medicago sativa) for export. The study was conducted on the Indian, Arab Authority for Investment and Agricultural Development (AAIAD) and Sedonix projects. In each project, three irrigation systems were randomly selected for the study treatments. Soil physical properties and textural class were determined at the Laboratory of the Department of Soil and Environment Sciences, Faculty of Agriculture, University of Khartoum. Water productivity (kg/m3) and crop productivity (ton/ha/cut) were determined from field data collected during the study period. SAS statistical package was used to analyze the data. The variations among the means were checked by the least significant difference (LSD). The results showed that, water distribution uniformity significantly (P ≤ 0.05) affected by three irrigated projects. Sedonix and India projects gave the highest water distribution uniformity as compared to AAIAD (71%). The highest water productivity was obtained under Sedonix and Indian projects (0.4 kg/m3/cut), while the lowest mean values (0.3 kg/m3/cut) was recorded in AAIAD project. On the other hand, Sedonix project gave the highest value for crop productivity (3.3 ton/ha/cut), while AAIAD project ranked the least (2.3 ton/ha/cut). It can be concluded that for optimum yields at each centre pivot location, proper technical guidelines for system management, operation and scheduling should be developed and followed.
