The production of sorghum (Sorghum bicolor) in Haiti faces a serious problem of yield at the national level (0.8 t / ha) which is mainly due to a lack of nutrients in the soil. To overcome this problem, the practice of the cultural association would be an interesting and very advantageous strategy. To this end, a study was carried out on the combination of two varieties of sorghum with maize (Zea mays) and pigeon pea (Cajanus cajan) in order to determine the most suitable cultivation method for growing sorghum in order to have better returns.
