Five Gliricidia sepium provenances, comprising three central American native populations and two land races, were grown at five sites. Replicated leaf samples were evaluated by an in vitro gas production technique, estimation of crude protein (CP), acid detergent fibre (ADF), neutral detergent fibre (NDF) and coumarin content. Differences between provenances in fermentation characteristics generally achieved statistical significance (p
