Satureja montana L. is a valuable perennial medicinal and aromatic plant belonging to Lamiaceae family. In this paper, the effects of mycorrhizal fungi (mix of spores of Glomus mosseae and G. intraradices) were studied on growth of the aboveground part of S. montana potted plants. Winter savory plants were grown in low carbonate Chernozem with high clay content and typical Arenosol with low plant-available phosphorus in both soil types. It is known that mycorrhizal fungi can improve the phosphorus nutrition of plants under phosphorus limiting conditions, enhance plant growth, and increases the yield of crop plants. Prior to the pot experiment made in a field, the winter savory was vegetatively propagated by softwood cuttings. Rooted cuttings were transplanted into 1.5 L plastic pots (one plant per pot) filled with Chernozem and Arenosol taken from the plow layer of the soils in a disturbed condition. The experiment was set in a split-plot design with 4 replications. The main plots were soil types, while sub-plots were 2 treatments (inoculated and non-inoculated plants) with 6 pots in a random arrangement in each repetition. Plants were watered regularly with an installed drip irrigation system and weeds were regularly removed. At 60 days after inoculation with mycorrhizal fungi, non-inoculated and inoculated plants were harvested and the absolute stems and leaves dry masses of plants were recorded. Inoculated plants, in both soil types, had higher absolute stems and leave dry masses compared to absolute stems and leaves dry masses in non-inoculated plants. The absolute stems and leave dry masses in Chernozem and Arenosol of inoculated plants ranged from 0.37 to 1.16 g and from 0.35 to 0.73 g, respectively; while in non-inoculated plants in ranged from 0.069 to 0.27 g and from 0.17 to 0.53 g, respectively. The mean values for absolute stems and leaves dry masses in Chernozem and Arenosol in treatments of inoculated plants were 0.75±0.21 and 0.58±0.10 g/plant; while in treatments of non-inoculated plants were 0.18±0.06 and 0.36±0.09 g/ plant, respectively. These preliminary results indicate that the mycorrhizal fungi have a positive effect on plant growth and development. Further research should focus on studying how mycorrhizal fungi affects the content of essential oil, as well as the supply of phosphorus to plants in the soils examined by this study.
