Abstract

Conservation coffee farming is practiced as shaded coffee systems which are important to soil conservation, biodiversity conservation, and ecosystem services such as nutrient cycling. Studies have been done on leguminous tree due to its ability to form nodules as simbiont of N-fixing bacteria. This study examined nodulation of four leguminous tree species commonly planted as shading tree in coffee farming at West Lampung. N fixing rate was analyzed using Acetylene Reducing Assay (ARA). The results showed that Gliricidia sepium had the highest genetic diversity and activity of nodule followed by Erythrina sububrams which had the highest nodule productivity. In contrast, Leucaena leucocephala had high nodule activity but low productivity while Paraserianthes falcataria had lower nodule productivity and activity. Key words: legume, shade tree, genetic diversity, nodulation, ARA
