The smothering effect of four legume covers, Canavalia ensiformis , Lablab purpureus, Mucuna pruriens and Calopogonium caeruleum , on Pennisetum polystachion ssp. setosum , a troublesome weed in rubber plantations in southern Thailand, was evaluated. Growing legume covers with Pennisetum , M. pruriens , C. ensiformis and L. purpureus caused strong suppression of Pennisetum in this order. Pennisetum grew little under 10% relative light intensity (RLI), but almost normally under 40% RLI. The three legume species generally attained lower RLI than C. caeruleum . The high shading ability of these three species was thought to contribute to the suppression of Pennisetum growth.
