The field experiment was conducted at Adola Rede district in Guji Zone of Oromia region. The objective of the study was to evaluate the performance of furrow irrigation systems on potato production and productivity. The furrow irrigation methods used were, i) Alternate Furrow (AF), ii) Fixed Furrow (FF) and Conventional Furrow (CF). The experimental design was a randomized complete block design (RCBD) with three replications. The climatic data of the Adola station were used for determination of water requirement and irrigation scheduling of potato crop using CROPWAT Version 8 software. The collected agronomic and yield data were subjected to ANOVA while irrigation water related performance indicators were computed using appropriate equations. The ANOVA indicated that there was significant (P ≤ 0.05) variation for marketable yield (t/ha), Unmarketable yield (t/ha), tuber weight (g), and No. tuber/plant, but in case of plant height (cm), and WUE (kg/m3) of potato tuber there were no significance difference but they were numerically different. Accordingly, the marketable potato yield for AF (18,472.84 kg ha-1), FF (13,744.75 kgha-1) and CF (24,557.72 kg ha-1) were significant different. Irrigation water productivity obtained were 8.286 kg m-3, 6.165 kg m-3 and 5.507 kg m-3 for AF, FF and CF irrigation methods, respectively. The water saved from AF and FF methods of irrigation was higher as compared to the CF method. And it can be concluded that the alternate furrow irrigation method (AF) was economic irrigation water productivity and environmental benefits for the study area, as it was higher water productivity (WP) compared to other furrow irrigation method. Therefore, the finding recommends alternate furrow irrigation for study area and all furrow irrigation users in irrigation water scarce area.
