Résumé de la publication

Maize production faces many constraints, including declining yields due to the steady decline in the fertility of cultivated soils and attacks by maize plants by pathogenic microorganisms, despite its importance and increasing demand for environmental pollution in Benin. The exploitation of new biological tools in agriculture opens up opportunities for innovation and improvement of crop systems to minimize the risks of environmental pollution and food contamination. This study aims to evaluate the growth of maize (Zea mays L.) in response to arbuscular mycorrhizal inoculation. Five (5) natives’ strains (Glomus caledonius, Rhizophagus intraradices, Funneliformis geosporum, Acaulospora capsicula, Acaulospora dilatata and Diversispora globifera) were tested in greenhouse following a device in complete random blocks. Inoculated plants and chemically fertilized plants were used as controls. The results showed that co-inoculation of Glomus caledonius, Rhizophagus intraradices and Funneliformis geosporuma improved the growth of corn plants (80.54%) and dry matter production (109.5%) compared to controls without chemical fertilizers and not inoculated. This study exhibited that native mycorrhizal fungi halve the recommended dose of 200kg/ha of NPK and 100 kg of Urea for corn fertilization. Results offered an alternative for the recovery of native mycorrhizal fungi in the form of organic fertilizer.
