Abstract

The work was performed in order to know the effects of different doses of a mycorrhizal inoculant in liquid support in growth variables, water relations and efficiency in the use tomato plants nutrients. For its realization, tomato plants INCA 9 [1] were grown in pots and placed in a polycarbonate greenhouse. Three doses were studied (D1, D2 and D3) 75 (D1), 150 (D2) and 300 spores plant-1, applied in seeding through injection by irrigation system and a non-inoculated control. At 25 and 40 days after germination (DDG ) evaluation of fungal variables, growth on dry biomass, leaf water potential and its components, stomatic conductance the concentration of foliar nutrients and efficiency use of these. The results showed that with any of the applied doses important benefits are achieved by symbiosis with increases of fungal variables, the content of dry biomass, water relations and the best efficiency in the use of nutrients. However, in general only with the application of the D1 dose, these benefits were obtained, resulting in this work the most appropriate and economic dose.
