The objective of this work was to verify allelopathical and physical effects of black velvet bean (Stizolobium aterrimum Piper e Tracy), jack bean (Canavalia ensiformes DC) and sunnhep (Crotalaria juncea L.) on the development of the weeds in American Lettuce and Cabbage crops. The experiment was performed at the Vegetables Sector of Universidade Federal de Lavras, in Lavras MG, from December 2001 to August 2002. The experimental design used was random blocks in the 4 x 2 factorial scheme with 3 repetitions. One factor consisted of the three leguminous, black velvet bean, jack bean and sunnhep, and the control (spontaneous vegetation); the other factor consisted of the cultures of Lettuce ( Raider cultivar) and Cabbage ( Kenzan cultivar). The results showed that the black velvet bean and jack bean controlled the sedge and the cabbage cultivation reduced the sedge infestation.
