INTRODUCTION: Tagetes lucida Cav. has been cultured in Cuba in gardens due to the beauty of its foliage, but to exploitation for medicinal aims it is necessary to establish its culture. OBJECTIVE: to determine before the fundamental agricultural parameters together with the necessary information to direct the experiment supplying the introduction to T. lucida culture. METHODS: authors used the species spreading by sexual multiplication and asexual by stakes, the establishing of the stretch with pegs and the percentage of rooted stakes, as well as the processes relative to culture: determination of 1 m wide planting in plots, to place 2 and 3 plant rows and a 30 and 40 cm distance among them; the assessment of the better variants was carrying out by results obtained in two foliage harvests. In parallel we made another preliminary experiment related to the distance among plants, where the rooted stakes were placed in two rows and the distance was of 30 and 50 cm among plants assessing 6 foliage harvests. RESULTS: under our conditions, seeds no germinate; multiplication of T. lucida must be carried out by terminal buds stakes obtained from young branches from the prior pruned selected mother plants achieving high percentages of rooted stakes that my be cultured in broad daylight during 25 to 30 days. Its culture by means of three row plantation by plots separated 30 cm was the better method and authors determined that in the second harvest yields are duplicate and remain increasing until the sixth harvest, where values decrease and the plants have a high ratio of lignified sprouts, suggesting the need of a low pruning looking for new buds or to eliminate the plantation, a feature that will be subsequently studied. CONCLUSIONS: these results are the basis for latter experiments to determine the agro-technology of this species due to its medicinal properties.
