Abstract
There are some pressurized irrigation projects launched in Ethiopia. Yet, there are no more research works on the performance evaluation of pressurized irrigation systems because of researchers believe that pressurized system has good performance. But practically, it is not true especially in developing countries such as Ethiopia, which has poor water resource management system. So to fill this gap, this research was studied on performance evaluation of Hormat Golina– 4 drip irrigation systems in Kobo Girana Valley. The objective of this study was to evaluate the performance of Kobo Girana pressurized irrigation, specifically Hormat Golina-4 drip irrigation. The emitter discharge and soil moisture content were collected from seven experimental plots fields. The emitter flow was collected by using a total of 63 catch cans, 9 catch can per plot area and measured by using graduated cylinder. Hydraulic performance indicators such as application efficiency (Ea), irrigation adequacy (Pa), equity performance (PE), dependability performance (PD), delivery performance ratio (DPR) and distribution uniformity characteristics; percent of clogged emitters (Pc), emission uniformity (EU), emitter flow rate variation (qvar), coefficient of variation (Cv) and uniformity coefficient (Uc) were evaluated accordingly. The average values of the above discussed parameters in the scheme were found that Ea (61.41%), Pa (41.52%), PE (0.33), PD (0.23), DPR (2.21), Pclog (33.33%), EU (47.71%), pvar (71.03%), CV (45.31%) and UC (53.42%), respectively. Results showed that the overall performance level of Hormat Golina – 4 drip irrigation systems is low and poor.
