Properties of gliricidia wood (Gliricidia sepium) intercropped with cocoa (Theobroma cocoa) in Malaysia / Mohd Helmy Ibrahim, Mohd Nazip Suratman and Razali Abd Kader

Trees planted from agroforestry practices can become valuable resources in meeting the wood requirements of many nations. Gliricidia sepium is an exotic species introduced to the agricultural sector in Malaysia mainly for providing shade for cocoa and coffee plantations. This study investigates its...
