Abstract
SUMMARY Upland rice and Stylosanthes guyanensis were sown simultaneously in pure and mixed culture at varying densities at Na Pheng, central Laos. Vegetative growth of the rice was negatively related to stylo density over the range o to 81 stylo plants/m. 2 Rice grain yield varied from 98·4 gm./m. 2 in monoculture to 63·4 gm./m. 2 when grown with 81 stylo plants/m. 2 Rice was more competitive than stylo, but stylo growth was relatively independent of rice density over the range 20 to 120 rice plants/m. 2
