In present study, three important multipurpose tree species, namely Aegle marmelos, Leucaena leucocephala and Parkia roxburghii were inoculated with better performing native arbuscular mycorrhiza fungi (AMF) species of the region. The AMF species viz., Acaulospora scrobiculata and Rhizophagus irregularis were inoculated individually and in combination under nursery conditions. Study consisted of four treatments i.e. three mycorrhizal [individual inoculation (A. scrobiculata, R. irregularis) and combined inoculation (A. scrobiculata + R. irregularis)] and a control (un-inoculated). All mycorrhizal treatments (individual and combined) significantly increased plant height, collar diameter, shoot, root and total dry weights of seedlings over control, barring few exceptions. This can be due to more volume of soil exploration for available nutrients and water by mycorrhizal plants than non-mycorrhizal plants, which improves plant biomass. The mycorrhizal dependency (MD) for AMF inoculants ranged from 42.6 to 44.3% (mean MD: 43.3%) in A. marmelos, -30.3 to 25.2% (Mean MD: 2.5%) in L. leucocephala and 51.2 to 58.8% (mean MD: 55.5%) in P. roxburghii. The seedling quality index, computed on the basis of growth parameters, also, showed that mycorrhizal treatments significantly improved plant heath. Thus, based on the results obtained from this study, we may expect a better establishment, survival and growth of the mycorrhizal inoculated seedlings in the fields.
