Atmospheric nitrogen fixation by gliricidia trees (Gliricidia sepium (Jacq.) Kunth ex Walp.) intercropped with cocoa (Theobroma cacao L.)
Aims The objective was to estimate the fixation of atmospheric nitrogen (Ndfa) by legume
(Gliricidia sepium) trees for the benefit of cocoa (Theobroma cacao) trees in agroforestry
systems. Methods Four sites where cocoa and gliricidia were intercropped and one site
where gliricidia, cocoa, and orange trees were grown as separate stands were selected in
Ghana. Ndfa in gliricidia and cocoa leaves (from all sites) and in shoot axes (in one site
only) was assessed by the 15 N natural abundance technique. Cocoa trees distant (> 10 m) …
