Abstract
The Mexican marigold flower (Tagetes erecta) is a plant native to Mexico, the uses are: pigments, flavoring, perfumery, ornamental, insecticides, nematicides and medicinal. In the soil there is a great richness of microorganisms mycorrhizal fungi and plant growth promoting rhizobacteria with an important role in the processes that affect the transformation of nutrients in the soil and their availability for plants and protection against phytopathogenic microorganisms. The objective of this work was to evaluate the effect of the use of beneficial microorganisms in the development of the cempasúchil flower compared with the application of a fertilizer. The bacterial strains were identified as 225, 254, 302 and an inoculum of mycorrhizal fungi. The Blue Garden fertilizer. Fresh weight, dry weight, number of flowers, root size were determined. A completely randomized experimental design and Tukey test were used. According to the results obtained, the best treatments that could have a potential use were the following treatments: fertilizer, strain 254, strain 302 and strain 254 and mycorrhiza. The use of beneficial microorganisms for the production of Mexican marigold flowers was shown to be effective and comparable with the application of fertilizer, therefore reducing its use and even eliminating it.
