ABSTRACT

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.

Effet de différentes densités de semis et de l’association culturale sur les performances du maïs (Zea mays) et du sorgho (Sorghum bicolor) en culture intercalaire avec le pois inconnu (Vigna unguiculata) dans la commune de la Croix-Des-Bouquets.

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.

In order to improve the yield and production of eggplant (Solanum melongena L.) by fertilization taking into account the problem of soil infertility, a lack of official recommendations on the use and optimal doses of fertilizers used and the low rate of their application in Haiti, this study was carried out on the fertilization of eggplant during the period from June to December 2019.

Etude du comportement de quatre variétés de riz ( face aux attaques des maladies foliaires et de la pourriture des gaines en Système de Riziculture Intensif (SRI) et en Système de Riziculture Traditionnel (SRT) à Bocozelle 5ème section communale de Saint-Marc.

In Haiti, the presence of the various rice diseases in the fields, the yield losses caused by them and the control mechanisms have been very little studied. During the period from June to October 2019, a study was carried out in Saint-Marc, more precisely in Bocozelle in the locality of “DEZIRE”, in order to study the behavior of four local rice varieties against the attack of certain fungal diseases in natural conditions in two different rice-growing systems (IRS: Intensive Rice Growing System; TRS: Traditional Rice Growing System).
