Establishment of Calopogonium mucunoides and Centrosema pubescens

Fabaceae family. They are shade tolerant plant and can quickly establish a dense cover and secrete chemical substances which inhibit the growth of other weeds. In recent years, both legume species had been used as cover plant for oil palm and rubber plantation. The goal of this work was to analyze t...
