Influence of Mineral Fertilization on the Capacity of Nodulation of Three Species of Legumes (Groundnut, Cowpea and Soybean)

Abstract

Groundnut (Arachis hypogaea), cowpea (Vigna unguiculata) and soybean (Vigna radiata) are the main food legumes grown in Côte 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 Côte 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 (<2 g) would be required for early growing legumes.

“…Indeed, aluminum-rich soils create toxicity in plants, resulting in a decrease in plant growth due to the precipitation of aluminum phosphates in the roots and blocking of cell division in root terminal meristems and aerial buds. Besides, exchangeable aluminum strongly inhibits the activity of soil microflora and particularly prevents the development of rhizobia [26].…”
