Abstract The growth of tomato (Solanum lycopersicum L.) plants under the influence of arbuscular mycorrhizal fungi (AMF) and PGPF was studied under natural conditions. The mycorrhizal efficiency index (MEI) and interactive effect of AMF with other fungi (IEF) were calculated on the basis of dry biomass of plants. Fresh weight, dry weight and length of shoot and root of the tomato enhanced due to the application of AMF alone or mixed with other plant growth promoting fungi (PGPR). The mycorrhizal efficiency index showed maximum biomass production due to the application of AMF + Aspergillus niger followed by AMF + Trichoderma harzianum. Interactive effect of AMF with other fungi (IEF) was calculated. It was highest with A. niger, followed by T. harzianum, T. viride, Alternaria solani and Rhizotonia stolonifer. When the plants were treated with the indigenous AMF consortium, shoot length increased by 83.2%, shoot fresh weight by 78.3% and shoot dry weight by 40.7% over control. The root length also increased by 6.3%, root fresh weight by 8.6% and root dry weight by 28.1% over un-inoculated plant.
