The present study was carried out in cattle farms in two localities of the department of Sucre, Colombia, established with colosoana grass (Bothriochloa pertusa (L) A. Camus) with the objective of determining the percentage of colonization of arbuscular mycorrhizal fungi (AMF) in roots of this grass species. Soil samples with roots were collected from cattle farms in the municipality of Sincelejo and San Marcos, from which the percentage of AMF colonization in roots was determined. The results of the analysis of variance for the percentage of colonization in roots of Colosuana grasses showed that there were statistically significant differences (p<0.001) in the samples analyzed, reporting values from 38 ± 44.17% in the municipality of San Marcos to 69 ± 71.17% in the municipality of Sincelejo. The results obtained show that mycorrhizal fungi colonize colosoana grass under different climatic conditions.
