Frequent monitoring of the performance of irrigation systems helps to distinguish whether the targets and objectives are being met or not. This study was conducted to compare performances of dragline and center pivot sprinkler irrigation methods using external and internal process performance indicators at Dodota expansion farm in Wonji/Shoa Sugar Factory, Ethiopia. The indicators relevant data include sprinkler discharge, soil moisture before and after irrigation; sugarcane harvested area, yield per ha, and price of a cane birr per quintal, water consumed, investment costs, and cost of production were collected. The external performances were checked on the basis of IWMI's performance indicators which include agricultural output indicators, water supply, and financial indicators. Similarly, application efficiency (AE), conveyance efficiency (CE), water storage efficiency (WSE), Christiansen uniformity coefficient (CU), and distribution uniformity (DU) were used to check the internal process performance of the two systems. The output per net harvested area and output per irrigation supply were found to be 73,947.93birr/ha and 2.03birr/m3 for center pivot and 69,184.81birr/ha and 0.26birr/m3 for dragline system which implies that center pivot relatively performs better. The relative irrigation supply and water delivery capacity were found to be 1.10% and 1.05%, for center pivot and 0.94% and 0.98%, for dragline. As the value is less than one in both cases, there is a constraint to meet the crop water requirement. The result of gross return on investment cost was found to be 34.41% for the dragline and 32.59% for the center pivot respectively. Whereas the result of financial self-sufficiency of the two systems were found to be ranges from 143% to165% for center pivot and133% to 158% dragline system. The result of self-sufficiency were greater than 100% in both cases which indicates that the out-grower capacities to manage irrigation system themselves without external assisting. The average result of AE and CE were found to be 85.54% and 95.145% for center pivot, and 48.41% and 93.515% for dragline system which implies that the center pivot utilizes water better than that of the dragline system. Further, the average values of CU and DU were found to be 55.61% and 47.27% for dragline, and 82.64% and 78.25% for center pivot system which indicates that the center pivot is performing better. In general, the center pivot system is relatively more efficient than the dragline system. However, the major problems to such under performance of the systems were observed to be pipe leakage and faulty on the electric pumps, which need prior attention to improve performance. Further, the frequent power supply interruption disturbs proper functioning of the pumps, which does have negative implication on the performance of the systems. Therefore, alternative power source shall be taken as an option to increase pumps running time.
