Allelopathic potential of the leaf and seed of Pueraria javanica Benth. on the germination and growth of three selected weed species

Pueraria javanica Benth. is one of the most common leguminous cover crop used in oil palm plantations of Malaysia. A study was conducted to determine the allelopathic potential of this plant, using the aqueous extract, sandwich and dish-pack methods, with the seed and leaf (of P. javanica) on three...
