Abstract:
Irrigation enhances agricultural production and improves the food supply, income of rural population,
opening employment opportunities for the poor, supports national economy by producing industrial crops
that are used as raw materials for value adding industries and exportable crops. This study was conducted
to evaluate the performance of Burabure small irrigation scheme at Jawi district, Awi zone, Amhara
Regional State, Ethiopia by using internal and external performance indicators. The most used internal
indicators include conveyance efficiency, application efficiency, overall efficiency and external indicators
such as, irrigated agriculture Performance, water use performance, physical performance and output
performance so as to recommend appropriate measures. The size of the irrigation scheme is command area
of 80 hectare. To achieve the objectives, primary and secondary data were collected. Primary data
collection includes measuring discharge at unlike points of main and field canals, soil moisture before and
after irrigation and depth of water applied. The secondary data includes determination of crop types, total
yields, farm gate prices of irrigated crops, area irrigated per crop per season and cost of production. From
analyses of the internal performance indicators, the conveyance efficiency, application efficiency and
overall efficiency were found to be 83.66%, 69.21% and 57.9% respectively. From the analyses of external
indicators, the outputs per cropped area were found as 10200 kilogram and 285600 birr per hectare, the
value of outputs per command area of the scheme were 5100 kilogram and 142800 birr per hectare and the
output per unit irrigation supply of 1.1 kilogram and 30.07 birr per cubic meter of water, output water
consumed was 1.58 kilogram and 80 birr per cubic meter. The irrigation ratio supply of the scheme was
found to be 0.5 which means 50% of the command area was under irrigation during the study period. The
evaluation hydraulic performance beneficiary participation in regular maintenance and canal clearing was
very low. By this reason a number of irrigation structures are affected by flooding, weed growth, erosion,
sedimentation, problems. So the numbers of functional structures initially installed has been becoming
nonfunctional. Therefore System, regular canal cleaning, maintenance of broken irrigation infrastructures
and economical application of water at the field which in turn results in upgrading the yield of crops.
