ABSTRACT: Groundnut (Arachis
hypogaea), cowpea (Vigna unguiculata)
and soybean (Vigna radiata) are the
main food legumes grown in Cote d’Ivoire and the localities of Haut-Sassandra. These legumes are highly
valued for their nutritional, agronomic and economic value. Groundnut, cowpea and soybean are the main food legumes grown in
Cote d’Ivoire
and in the localities of Haut-Sassandra. On the other hand, Ivorian soils are
characterized by a tendency towards acidification and a decrease in the content
of nutrients such as phosphorus and nitrogen which have a direct impact on the
products. To restore soil fertility, farmers use mineral fertilization. However,
this fertilization has an influence on the nodulation of these legumes. The study took place at Jean Lorougnon University. We adopted
a completely random experimental block
device. The parameters measured included the number of nodules, the length and weight of the plant, the length and weight
of the root system. Our results showed that mineral fertilization reduced the
nodulation capacity of legumes. However, a small dose of phosphorus ( g) would be required for
early growing legumes.
