An experiment was conducted to determine the effect of arbuscular mycorrhiza fungal (AMF) isolates on various growth parameters and enzymatic activity in maize grown under protected conditions. One hundred and eight AMF isolates, collected from apple, pear and cherry rhizosphere, were chosen to assess their efficiency in improving growth of maize cv. “C6”. The plant height, root biomass, shoot biomass, root mycorrhizal colonization and root and shoot phosphatase in AMF inoculated maize plants ranged from 16.0 to 27.9 cm, 2.75 to 4.60 g, 9.37 to 14.26 g, 17.78 to 65.15%, 3.59 to 40.66 m moles PNP/g fresh root weight and 3.20 to 30.73 m moles PNP/g soil, respectively, as compared 18.1 cm, 3.25 g, 10.74 g, 0%, 3.66 m moles PNP/g fresh weight and 3.33 m moles PNP/g soil in control. The AMF isolates collected from different hosts, revealed variable behaviour with respect to plant growth improvement and enzyme activities. The AMF isolates showed almost similar pattern with a little variation. The AMF isolates of cherry, apple and pear rhizosphere showed 23.2 to 65.2, 19.8 to 53.1 and 17.8 to 61.5% root colonization, respectively. On the basis of initial screening twenty most efficient isolates were compared statistically which showed significant increase of 7.0 to 54.6, 12.6 to 41.5 and 11.7 to 32.8% in plant height, root biomass and shoot biomass, respectively, in maize.
