The searching was carried out in the provinces of the San Martín, region: Moyobamba, Lamas and Huallaga; Aiming to determine the relationship between the population of native arbuscular mycorrhizal fungi with Meloidogyne spp. in coffee plantations (Coffea arabica). The investigation was of correlational type, the design in chance (DCA) with trifactorial arrangement: 2A(Epoch)x3B(Province)x3C(Variety) obtaining 18 treatments. The first samples were collected between March and May (rainy season) and the second ones in August (dry season) in 2017. The highest values were: for mycorrhizal colonization, T6 with 12.49% in mycorrhizal intensity (IM) and 50.91% in mycorrhizal frequency (FM) (rainy season), IM: 15.37% FM: 53.07% (Lamas) and IM: 16.70% FM: 61.67% (national variety); For the number of live spores, with an average of 55.11; 56.30 and 53.47 spores/10g. of dry soil in dry season, Moyobamba and national variety respectively. In extra-root mycelium, 50.87 cm/g. of soil (rainy season), 45.61 cm/g. of soil (Lamas) and 42.91 cm/g. of soil (national variety). For Meloidogyne spp., in number of gills, 371.71, 375.2 and 485.80 galls/5g. of roots in the rainy season, Lamas, national variety correspondingly; the population in the soil, T8 with 13.62 individuals/100g. of soil (rainy season), 12.4 individuals/100g. of soil (Huallaga) and 11.53 individuals/100 g. of soil (variety pache). Concluding that the highest values were in the rainy season, it is indicated that the attack of Meloidogyne spp., accelerates the development and colonization of the fungus inside the root.
