THE INFLUENCE OF SHADE COFFEE AGRO-ECOSYSTEM ON PRODUCTIVITY AND FARMING SUSTAINABILITY. Shade trees provide ecological benefits such as soil conservation, biodiversity conservation, and providing nutrient through litter fall and nitrogen fixation by legume trees. Therefore, shade tree is a key factor for sustainability coffee production. To evaluate productivity and sustainability of coffee agroecosystems a study was conducted at Sumberjaya Sub-district, West Lampung, Indonesia, during 2007-2010. Farmers were interviewed and two plots of Coffea canephora were set. Plot I was a long-term experimental plot, established from shrub to young coffee agro-ecosystems with treatments of open-grown (sun) coffee and Gliricidae sepium, Erythrina indica and Michelia champaca shaded-grown coffee. Plot II was mature coffee fields of 15 years old with the same types of shade trees. The results showed that type of coffee agro-ecosystems determined productivity which legume-shaded coffee were higher than non-legume shade coffee or sun coffee. Based on the value of Sustainable Yield Index, Benefit Cost Ratio, Net Present Value, and Internal Rate of Return, Gliricidae sepium and Erythrina indica shaded coffee were more visible therefore more sustainable than 2 others coffee agro-ecosystems. Based on the survey and experimental plot, productivity of coffee agro-ecosystems of 3-26 years old showed two maximum points resulted in a regression of polynomial model. Key words: coffee, shade tree, productivity, sustainability
