Abstract

The aim of study was to assess the overall performance of Bedene Alemtena small scale irrigation scheme using internal and external performance indicators. Primary data were collected from three farmers’ field situated at the upper, middle, and downstream of the main canal. Discharge measurements and soil sample analysis were conducted, and secondary data were collected from Halaba Kullito Bureau of Agriculture. CROPWAT 8.0 computer model was used to calculate the crop water requirements. From the analysis of data, the indicative values of the output per unit command area for Bedene Alemetena were 65423.669 Br/ha, similarly the output per unit cultivated area for this scheme was 58940.242 Br/ha. The output per unit water consumed was 14.588 Br/m3 and the results of application efficiency, distribution efficiencies and water productivity are 54.9%, 90.23% and 4.314 kg/m3 respectively. According to these results, it can be concluded that expected results are best but to sustain the scheme more than this; it is recommended that all activities in the irrigation network should be monitored and checked, technical requirements should be met, training and extension should be enhanced, evaluations should be performed on a seasonal basis and the results should be delivered to the relevant individual and institutions with an efficient monitoring and evaluation system. Water users associations and cooperatives that undertake the operation and management of irrigation scheme should be empowered more than done in this time.
