Inoculation of Efficient Microorganisms (ME) and Arbuscular Mycorrhizal Fungi (FMA) in lettuce: a field work conducted in the community garden (HC) Vapabuçu, municipality of Sete Lagoas- MG

Abstract

Commercial substrates for the production of vegetable seedlings, in general, do not contain
arbuscular mycorrhizal fungi (AMF) and efficient microorganisms (ME). These favor a nutrient
acquisition and a resistance to biotic and abiotic stresses. We evaluated a response to inoculation
by two types of FMA inoculum (Rhizoglomus sp and On Farm) and EM in two phases:
seedling and seedling production. The study was carried out in the community garden (HC)
Vapabuçu, with lettuce cv. Tainá. A lettuce, cultivated at HC, presented a low rate of mycorrhization
when not inoculated. An inoculation of AMF in the nursery stage provided increases
in yield and mycorrhization rate. In the nursery phase, a seedling inoculation utilized in the
nursery phase showed a tendency of production gains, especially when inoculated with the
fungus MA Rhizoglomus sp. The technology of inoculation of microorganisms is simple and
can be operated by the farmer himself, increasing his autonomy in the productive processes
and ensuring the sustainability of his systems.
