Abstract
Farmers have a good understanding of the positive and negative interactions between the shade canopy and the coffee crop. Coffea arabica L. is extensively cultivated by households under a variety of shade trees in Anfillo District of Kelem Wollega Zone. This study was conducted in Anfillo District of Kelem Wollega Zone, Oromia Regional State. The aim of this study is to identify the most important shade tree species and to document farmers' knowledge on the environmental and socioeconomic benefits of the shade trees in coffee production systems. Ethnobotanical data were collected through structured and semistructured interview, guided field walk and field observation. Data analyzed using the standard ethnobotanical methods. A total of sixty five informants which are between the age of 25-70 were involved in this research, of which eight were selected as key informants. of which, eight were selected as key informants. A total of twelve coffee shade tree species that have more than 10 major use categories were recorded. The ranking analyses showed that Albizia gummifera, and Millettia ferruginea as the most preferred coffee shade trees. Leguminous trees (Fabaceae) are the most diverse group in both semi-forest and semiplantation coffee system. Farmers preferred these species in their coffee plantation due to their soil fertility improvement. In addition to shade provision, coffee shade trees are important in improving soil fertility (leaf fall provide mulch), increasing the yield and size of coffee beans, and others. However, denser shading resulted in lower yields and under full sun, cup quality and coffee bean size decrease. There is a need to determine the appropriate density of shade trees to maximize the productivity of coffee plants.
