The aim of this work is to study the effect of a composite endomycorrhizal inoculum on the growth of argan tree plants under nursery conditions. Analysis of the obtained results after ten months of inoculation showed a significant effect on the growth of the inoculated plants as compared to the controls. Indeed, the mean values of arial fresh weight (27.54 g) and root (23.64 g). The length (59.87 cm), the collar diameter (3.93 cm) and the number of branches (7.37) of the inoculated plants are superior to those observed in the control plants, 13.36 g, 13.43 g, 35.83 cm, 2.83 cm and 4.66 cm, respectively. In addition, frequency (100%), intensity (63.66%) and arbuscule contents (51.79%) and vesicles (25.52%) are very important. The roots of the control plants are not mycorrhizal. The mean number of spores formed in the rhizosphere of the inoculated plants is 246 spores per 100 g of soil. These spores are those of 29 endomycorrhizal species belonging to six different genera: Acaulospora, Scutllospora, Pacispora, Glomus, Entrophospora and Gigaspora. Representatives of the Glomus genus are the most dominant.
