Arbuscular mycorrhizal fungi (AMF) play a crucial role in facilitating nutrient absorption and enhancing plant growth through a mutualistic symbiosis in their roots. In the San Martín region, coffee and sacha inchi crops benefit from this symbiosis, but the relationship regarding this composition remains unknown. Thus, the following objectives were proposed: a) Identify the AMF through DNA sequencing with Illumina, and b) Investigate the richness and composition of the AMF in relation to geography and plant age. For this, root samples were taken from five locations in the San Martín region: Lamas, Bellavista, El Dorado, and Picota for sacha inchi (plots of 1 year and 2 years); and Lamas, El Dorado, and Moyobamba for coffee (plots of 1 year, between 3 and 4 years, and older than 6 years). Molecular characterization was performed using nested PCR, and sequencing was done with Illumina. Significant changes were determined in the alpha and beta diversity of coffee based on age and locations. Likely because environmental selection over time caused biotic and abiotic constraints that favored a set of AMF taxa. However, for sacha inchi diversity, only geographic influence was observed. Perhaps the time period was not long enough to show variations, but alterations due to agricultural practices did have significant relevance for this crop. This is a significant contribution to understanding the relationship of AMF composition with these plants and the variables studied, and also serves as a basis for improving coffee and sacha inchi cultivation.
