ResumoThe experimental work was carried out in the areas belonging to the agriculturalproduction cooperative Augusto Cesar Sandino de La Palma, Pinar del Rio, Cuba, with the aim of evaluating the effect of the arbuscular mycorrhizal fungi G. cubenses and G. intraradices, in the initial growth phase of the Z. mays crop, using a Pardo clay soil with a fine texture, from the cooperative itself. To set up the experiment, a completely randomized design with four repetitions was used. The variables of growth, phytomass and nutrients in the crops were evaluated, as well as the percentages of colonization and visual density of the AMF species studied. The results showed that the highest the arbuscular mycorrhizal fungi efficiency - plant, in terms of colonization percentages and visual density, was obtained with G. cubenses, as well as the applied arbuscular mycorrhizal fungi strains show a favorable behavior in the evaluated indicators respectively, achieving height increases and diameter of the stem in the plants, without the need to apply fertilizers during the first 45 days after the seeds germinate.
