abstract = "Glycine max is one of the most common crops produced in nurseries. Application of microorganisms such as arbuscular mycorrhizal fungi to enhance salt tolerance is quite well-known, but the interaction of mycorrhiza and salinity to growth and nutrient uptake of salt-sensitive soybean (Giycine max) seedlings has been less studied. Therefore, the aim of this study was to investigate the effect of AMF inoculation on growth and nutrient uptake of soybean grown under different salinity levels. A pot experiment was conducted under green-house conditions in Hawassa University College of Agriculture. The non-colonized seedlings and seedlings colonized by Gigaspora rosea and Rhizophagus clarus were exposed to salt stress by irrigation with 50 mM, 100mM and 150mM NaCl solutions. There was no mycorrhizal colonization recorded in the control plants. All plants inoculated with AMF showed mycorrhizal colonization (the formation of arbuscules and vescicles) and the formation of spores. Salt stress significantly depressed the colonization and spore formation of both Gigaspora rosea and Rhizophagus clarus. The maximum root length colonization (RLC) and spore density (SD) were recorded in plants grown under salt free soils (non-salinized soils) while the minimum RLC and SD were observed in plants grown under highly salt stressed (150mM NaCl) used soils. Mycorrhizal association  markedly increased both growth performance (length and diameter of stem, length of root, number of leaf, wet and dry weights of shoot and root) and nutrient uptake (concentrations of  N, P, K, Ca and Mg) of soybean seedlings exposed to salt stress at all salinity levels. Belsa 95 groups inoculated with Gigaspora rosea shown better growth performance and nutrient uptake than those groups inoculated with Rhizophagus clarus while AfgatM5 groups inoculated with R. clarus shown better growth performance and nutrient uptake than those groups inoculated with G. rosea. Generally, it is clear that mycorrhizal inoculation possesses the potential to enhance salt tolerance of Glycine max. Therefore, intelligent nursery inoculation with commercial AMF seems to be a viable solution to promote growth and mineral uptake of Glycine max that are grown under salinity-stressed soils.",
