Arbuscular mycorrhizal fungi (AHM) are edaphic soil microbial that establish symbiosis with the plants influencing positively its growth and development. An experiment was conducted in experimental areas of the National Institute of Agricultural Sciences to study tomato (Solanum lycopersicum L. cv. 'Amalia') plants response to liquid biofertilization with Glomus cubense. Tomato seeds were disinfected with a solution of sodium hypochlorite 10 % for 10 minutes and it were sown in polyethylene trays at two seeds by cell. Glomus cubense (Y. Rodr. & Dalpé) was studied and reproduced in the culture collection of the Laboratory of Mycorrhizae and it was inoculated in the seedling stage. Inoculation was performed once during the experiment and the cycle was applied irrigation function of water evaporation tray. Three doses were inoculated AMF: 10, 20 and 40 esporas.mL^-1 water. Four treatments were studied following a completely randomized design. Indicators vegetative development (dry mass leaf and surface leaf) and mycorrhizal functioning (frequency and intensity colonization and total protein extraction) were evaluated. Results showed positive effect on vegetative development indicators and tomato mycorrhizal functioning of liquid inoculant. We found that a dose of 20 spores per plant was the best response to said.
