High yields in intercropped only be attained with the adequate selection of an adequate plants arrangement system; therefore the aim of this project was to investigate which plat arrangement would better perform in a common beans/castor bean intercropping system. The experimental design was a completely randomized bloc with five replicates and four simultaneous sowings: beans sown on the castor beans row; beans sown between castor beans rows; beans sown on the row and between castor beans rows, and common beans and castor beans in monocrop. Results obtained from castor beans crop yields were not affected when intercropped with common beans. This intercropping system with castor showed that common beans cv. Pérola on the row and between rows provided higher yield of the legume. In general, the intercropping of common beans+castor beans is more efficient than the single crop system.
