Hormat-Golina small irrigation scheme was found in Ethiopia that was contributes to enhancing food security and economic growth of the local society. This scheme have two types of irrigation systems. Drip and furrow irrigation types were practicing at Hormat-schemes, but water productivity of this irrigation type were not evaluated yet. Thus, the aim of this paper was to evaluate the water productivity under drip and furrow irrigation systems. CROPWAT8.0 tool was used to determine the crop water requirement for selected crops. The well discharge capacity were determined by regular field measurements. Under drip irrigation method crop water productivity resulted were 1.53, 1.02, 1.06 and 2.24 kg/m3 for chickpea, garlic, onion, and watermelon respectively. Whereas, under the furrow irrigation method, the crop water productivity resulted were 0.52, 0.66 and 1.52 kg/m3 for chickpea, onion, and watermelon respectively at the first season. However, at season two it were resulted as 1.18, 1.03 and 2.29 kg/m3 for chickpea, garlic, and watermelon respectively under drip irrigation system and 0.47, 0.57, 0.64 and 1.43 kg/m3 for chickpea, garlic, onion, and watermelon respectively under furrow irrigation system. Moreover, the economic water productivity under drip irrigation method has resulted as 0.34, 1.29, 0.41 and 1.20 $/m3 for chickpea, garlic, onion, and watermelon respectively; and also 0.14, 0.25 and 0.85 $/m3 for chickpea, onion, and watermelon respectively under furrow irrigation system at the first season. But, in the second season, it becomes 0.4, 1.41 and 1.74 $/m3 for chickpea, garlic, and watermelon respectively and 0.15, 0.77, 0.31 and 1.06 $/m3 for chickpea, garlic, onion, and watermelon respectively with the respective of drip and furrow irrigation methods. Based on these results drip irrigation system is the advisable method for such irrigation schemes, and also it is the water saver irrigation mechanism in water scarce area.
