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.
