In polycultures with high interspecific competition a decline in yield of one crop resulted in an increase in yield of another crop. Total polyculture yield was at a maximum at some point between zero interspecific competition and a point at which interspecific competition was equal to intraspecific competition.  aConsorciação de Cultura  aFeijão  aMilho  aSistema de Cultivo
