| dc.description.abstract | This study was conducted to evaluate the performance of Betho and Sitr-dirma small scale irrigation schemes. Evaluating the performance of Irrigation systems could play an important role in attaining to sustainability. The indicators used were Internal and External performance indicators. The selected internal indicators were Conveyance and application efficiency while the external indicators were water use, agricultural output and physical indicators. The conveyance efficiency was varied from 60.65% to 82.33% for Betho and 72.80% to 85.20% for Sitr-dirma small scale irrigation schemes. Here, Sitr-dirma is efficient than Betho because in the later scheme as observed water management practices was poor. The application efficiencies were in the order of 49.579% for Betho and 45.11% for Sitr-dirma small scale irrigation schemes. As observed from the result Betho performs better than Sitr-dirma, this was because the method of application of water at Betho was good. The result from the analyses of the water use performance indicators, the ratio of Relative Water Supply and Relative Irrigation Supply were 1.03 and 1.15 for Betho and 0.93 and 1.11 for Sitrdirma irrigation projects. The output per unit irrigation supply were 0.73$/m3 for Betho and 0.74$/m3 for Sitr-dirma. The output per water consumed was 0.66 $/m3 for Betho and 0.63$/m3 for Sitr-dirma. Outputs per cropped area were 3456.05 $/ha for Betho and 3209.37 $/ha for Sitr-dirma. The value of the output per command area were 4485.21$/ha for Betho and 4263.88 $/ha for Sitr-dirma. The irrigation ratio and sustainability were in the order of 87.6% and 129.8% for Betho and 84.4% and 132.9% for that of Sitr-dirma. In irrigation ratio Betho (87.6%) was better than Sitr-dirma (84.4) which means the degree of utilization of available land for irrigation at Betho was good, but with respect to sustainability Sitr-dirma (132.9%) has higher value than Betho (129.8%), this indicated that the irrigated area under irrigation is expanding at Sitr-dirma than Betho | en_US |
