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. This is why this work aimed to develop technical packages that helped improving crop yields, to imply at the same time an improvement of the profit. A variety of maize (Chiken corn) and sorghum (Baton Moyiz) intercropped respectively with the cowpea CAR9 were used.
Optimisation et effet de différentes doses d’azote, de phosphore et de potassium sur la performance agronomique de 3 variétés d’aubergine (Solanum melongena L.) en condition de sol alcalin à Cabaret
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.
