Equisetum giganteum L., commonly known as Horsetail, is a medicinal, herbaceous, marsh plant. Its harvesting is entirely from its natural habitat, and it is currently in danger of extinction. Given this situation, it is a priority to conduct studies on its propagation. The objective of this experiment was to evaluate the effect of substrates and containers on the vegetative propagation of horsetail. The experiment was carried out between July and September 2023, at the Multidisciplinary Center for Technological Research of the National University of Asunción. The experimental design used was completely randomized with the combination of factor A corresponding to the substrates 100% washed sand, 100% earthworm humus and the combination of humus and sand at 50% and factor B to containers with or without drainage with 12 replications, totaling 72 experimental units. The variables were evaluated 45 days after implantation; the percentage of survival, length of shoots and rootlets, number of shoots and rootlets were determined. The data were subjected to the nonparametric 5% Kruskal-Wallis test. The results showed that the 100% washed sand substrate in undrained containers had the best averages for the variables evaluated, making it an alternative for seedling production.
