Objective: To evaluate the effect of mycorrhizal inoculation and the use of vermicompost on the growth of red cedar (Cedrela odorata L.) seedlings under nursery conditions. Materials and Methods: The treatments were with and without a Glomus intraradices inoculum, combined with different amounts of vermicompost in the growth substrate (0, 10, 20 and 30%), in a completely randomized block design. The variables evaluated were plant height (PH), stem diameter (SD), number of leaves (NL), dry weight (DW), mycorrhizal colonization (MC) and number of spores (NS). Results: The addition of vermicompost to the growth substrate improved the growth of C. odorata seedlings, the best treatment being 30% of vermicompost without mycorrhizae. The percentage of mycorrhizal colonization and number of spores per 100 g of soil decreased when increasing the amount of vermicompost in the substrate.Study Limitations/Implications: None.Findings/Conclusions: Vermicompost was the leading promoter of C. odorata plant growth under nursery conditions.
