20 days later, we inoculated a part of seedlings with the symbiotic fungus by placing the media containing the roots and the fungus hypha near the roots of seedlings. Three months later, the measure of the impact of symbiotic fungus on the plant growth was taken by comparing between inoculated plants, the control plants and plants treated with specific chemical fertilizer.

The results show a net positive influence of the symbiotic fungus on the growth of squash seedling comparing with control and with the seedling treated with chemical fertilizers especially root systems. Concerning melon plants, the positive effect of the fungus was only comparing with control. We can conclude that the use of Am fungus give a real positive influence on the growth of plants especially comparing with control and better or similar compared with plant treated by chemical fertilizer.
