South-West Ethiopia is known for tropical humid and crop cultivation including coffee Arabica which is cash crops to Ethiopian as well as for the world. Coffee production in Ethiopia especially in jimma zone is dependent on rainfall. Different study has been conducted on coffee productivity and its quality improvement. In Ethiopia, there exists a wide genetic diversity among Arabica coffee cultivars for yield potential, quality and resistance to diseases. However, in spite of periodic and frequent occurrence of drought, little attention has been paid to study the response of coffee cultivars to moisture stress. Coffee cultivars are very sensitive to soil drying based on differences in mean stress score, percent plants wilting at noon and recovering during the night time, mean days to complete wilting, rate of leaf shed and rate of survival at seedling stage. On the other hand, soil moisture depletion level effect coffee growth, yield and water productivity. Proper irrigation scheduling, by which the precise timing and amount of irrigation determined has long been advocated as an improved water management technique. In this regard decreasing or increasing the amount of allowable soil moisture depletion level had significantly reduced the coffee yield, water productivity and plant height in areas like Jimma zone Gera woreda. Thus proper determination of coffee water requirement is essential, since CWR was lowest during the initial stage and highest during mid-season stage. Hence, the aim of this review was to provide information on sensitivity of coffee genotypes to moisture stress at seedling as well as reviewing the allowable soil moisture depletion level of coffee Arabica in case of Jimma area.
