ALVAREZ, Manuel; TUCTA, Franz; QUISPE, Evelyn  and  MEZA, Victor. Incidence of the inoculation of beneficial microorganisms in the strawberry (Fragaria sp.) crop. Scientia Agropecuaria [online]. 2018, vol.9, n.1, pp.33-42. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2018.01.04.

The effect of beneficial microorganisms (MOBs) on the development of the strawberry crop (Fragaria sp.) was evaluated. The investigation was carried out in three phases. (i) First: in the province of Azuay - Ecuador, samples were taken from different plants located on three altitudinal floors with different climatological characteristics. (ii) Second: in the laboratory of the National Agrarian University La Molina, in Lima - Peru, with each plant sample, the mother solution was prepared, as well as culture media for MOBs, after which the beneficial microbial flora was identified. (iii) Third: in the field stage, a microbial consortium was inoculated on the ground, with four repetitions for each altitudinal floor; subsequently strawberry was planted. In the culture medium the presence of yeasts, Bacillus spp., Lactobacillus spp., and actinomycetes were found. It was verified that, according to the provenance, the microorganisms have heterogeneous effects in the development of the plants. It is concluded that in each altitudinal floor exist beneficial microorganisms according to the plant species, that their inoculation in the soil increases the number of leaves, as well as it favors the longitudinal, diametral and roots development of the strawberry plants.
