To examine the intercropping system of roselle with mung bean, a field experiment was carried out at the research farm of the University of Zabol. Split plot experiment performed on the basis of an RCBD with three replications. The main plot consisted of three tillage systems (no-till, minimum and conventional tillage) and the subplot was 5 planting ratios (sole culture of roselle and mung bean, 50% roselle + 50% mung bean, 25% roselle + 75% mung bean, 75% roselle + 25% mung bean). The parameters studied in this experiment included land equivalent ratio (LER), relative crowding coefficient (RCC), completive index and dominance index. The highest RCC was obtained at no-till (3.02) and the lowest RCC was obtained in conventional tillage (2.51). The highest RCC was obtained at 25% roselle + 75% mung bean (4.63). Among different tillage systems, the greatest dominance index of roselle was obtained from the no-till system (0.79). The interaction of tillage systems and different ratios of intercropping showed that the highest dominance index for roselle was obtained from no-till and intercropping of 75% mung bean + 25% roselle (1.69). The highest LER was obtained in plants grown at 75% mung bean + 25% roselle. Comparison of competitive indices of intercropping of roselle and mung bean showed that roselle with higher economic yield is more competitive than mung bean.
