Inoculation Effect of Arbuscular Mycorrhizal Consortiums in Coffea arabica, Caturra Variety in the San Martín Region. Inf. tecnol. [online]. 2018, vol.29, n.1, pp.137-146.

The objective of this study was to determine the inoculation effect of nine consortiums of Arbuscular Mycorrhizal Fungi (AMF) in coffee seedlings Coffea arabica, Caturra variety, compared with a control (without inoculation), during seven months under greenhouse conditions. The production of coffee in San Martín-Perú, is one of the most important agricultural economic activities. An alternative to increase its production is the employment of AMF. The experiment was done using a completely randomized design, with nine treatments and three repetitions (6 plants/repetition). The origin of the mycorrhizal consortia came from coffee farms of provinces distributed at San Martín Region. The study was performed evaluating parameters as colonization (%), extraradical mycelium length, plant height, leaf area, aerial biomass and dry root mass. The results of the study show that three of the nine consortia studied were more efficient during the growth and development of coffee plants seedlings.
