Effect of the arbuscular mycorrhiza on tomato plants in the pot experiment was studied. Three different fertilization regimes (optimum - H1, stress a - H2, stress b - H3) and three different mycorrhizal treatments (control, Glomus mossae - Gm, Glomus intraradices - Gi) were used. Tomatoe yield, nutritional characteristics (vitamin C content, phosphates and minerals content, total antioxidant capacity), and level of root colonization were studied. The yield was influenced by the basic dose of the fertilization, especially in the H2 and H3 treatments. The highest yield was in the H2 treatment in Gm (938 g per plant). The positive effect of the inoculation resulted in the increased content of the vitamin C. The highest significant influence was observed in the H2 treatment (plants inoculated with Gi) with the average content of the vitamin C 289 mg/kg. The average rate of the colonization was in the range from 39 % to 65 %.
