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.

Intercropping is the main farming method practiced in Haiti. It occupies more than 65% of the useful agricultural areas, with the dominance of cereals (maize, sorghum), cultivated mainly with legumes such as the cowpea. Poor farming practices is one of the main constraints encountered in this system, especially in terms of densities. The plants are grown at low seed densities, so finding an optimum density that promotes better yields is difficult.
