The problem of planting density and irregular rainfall are two major constraints that farmers face in growing maize. Many farmers do not master the practice of planting density and cannot optimize their yields. To this end, a study on the effect of different planting densities and mulch on the agronomic performance of three varieties of “zea Mays” maize was carried out in the commune of Croix des Bouquets in the locality of Digneron with the aim of finding which combination of density and mulch will optimize yield. The study area receives about 1022 mm of rain per year and according to the classification of Köppen and Geiger the climate is AW with an average temperature of 26.20 Celsius.

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.
