Abstract:
Appropriate irrigation practice is relevant for increased crop productivity and conservation of water resources. No or little concern has been given to the necessity and extension of existing irrigation technologies while the impacts of climate change are visible throughout Ethiopia.A field study was carried outfor determining optimal irrigation scheduling for maize production at Teppi, South west Ethiopia for three successiveyears. The objectivesof the study were to evaluate the effect of different irrigation regime (different soil moisture depletion levels)on yield and water use efficiency of hybrid maize (BH-140). The treatments were set based on the recommended soil moisture depletion levels for maize (MAD = 0.55). Then five levels of soil moisture depletionwere selected for evaluation of optimum irrigation scheduling namely SMD1 (60%), SMD2 (80%), SMD3 (100%), SMD4 (120%), and SMD5 (140% of the recommended value, 0.55). The result indicated that SMD4 has significantly (P
