| dc.description.abstract | This study was conducted to evaluate the performance of two small scale irrigation schemes at North Wollo Zone, Amhara Regional State, Ethiopia using process and comparative performance indicators. The irrigation schemes were Golina with command area of 400 ha and Kokono with 80 ha command area. To achieve the objectives, primary and secondary data were collected. Primary data collection includes measuring discharge at diversion weir, soil moisture before and after irrigation and depth of water applied. The secondary data collection includes determination of crop types, total yields, farm gate prices of irrigated crops, area irrigated per crop per season, and cost of production. The two schemes were compared using minimum sets of comparative performance indicators which include agricultural, water use and physical performance indicators. The process indicators which include conveyance, application and storage were used to check the performance of the two irrigation schemes. From the analyses of the internal performance indicators, the conveyance efficiencies , application efficiencies, storage efficiencies and overall efficiencies were found to be 76.58%, 52.51%, 48.38% and 40.21% for Golina scheme and 38.02%, 65.93%, 44.89% and 25.07% for Kokono scheme respectively. From the analysis of comparative indicators, the outputs per cropped area were found as 1111.67 and 753.38 US$ ha-1, the value of the outputs per command area of schemes were 2166.37 and 768.44 US$ ha-1, the output per unit irrigation supply of 0.11 and 0.1US$m-3, output per water consumed was 0.2 and 0.18 US$ m-3 for Golina and Kokono irrigation schemes respectively. The water use performances of the two schemes were compared, relative water supply found to be 1 at both schemes and relative irrigation supply was found as 4 and 1.7 at Golina and Kokono respectively. The irrigation ratio of Golina was found to be 0.974 which means 97.4% of command area was under irrigation and that of Kokono was 0.51 which means about 49% of command area was not under irrigation during study period. In general, based on the assessment carried out, Golina irrigation scheme performed better than Kokono scheme. | en_US |
