Abstract: The use of Arbuscular Mycorrhizal Fungi (AMF) is considered one of the effective organic ways to increase the crops productivity. The aim of this study was to evaluate the growth promoting effect of three mycorrhizal fungi (Glomus cubense, Rhizophagus intraradices and Funneliformis mosseae) on maize crops in a ferruginous soil of Northern Benin. Maize seeds were inoculated with mycorrhizal fungi in combination with or without minerals fertilizer. Study was conducted in a completely randomized block design with nine treatments and four replicates. The endomycorrhizal infection was evaluated on 68th days of sowing while the crop was harvested after 90 days. Results of study revealed that application of AMF have significant effect (p< 0.01) on the growth attributes and performance of maize. Compared to the control, maximum height (increases of 29%) was recorded in the plants treated with a complete dose of NPK, followed by the plant treated by F. mosseae combined with 50% NPK (increases of 20.28%). Same treatments have better leaf growth, high production of biomass (air and ground) and better seed yield. As far as endomycorrhizal colonization is concerned, plants inoculated with R. intraradices had best frequency of mycorrhization (38.50%) and a high number of spores (1.73 spores/g soil), while those inoculated with F. mosseae had the best intensity of mycorrhization (11%). Results of present study suggest the use of endomycorrhizal fungi for enhancing the growth and maize seed yield in ferruginous soil in the North of Benin.
