Objetive: The present study analysed the effects of the Volatile Organic Compounds (VOCs) of the foliage and flowers of Ocimum basilicum, Tagetes ere cta and Origanum majorana on the growth of the Saladette (Solanum lycopersicum Mill.).Design/Method/Approach: The aromatic species in their phase of development and flowering were transplanted between grooves of tomato plants. The treatments (Association of aromatic species 1, 2 and 3 in development tomato plant, association of aromatic species 1, 2 and 3 in flowering tomato plant and tomato plant without association) were randomized under a completely randomized experimental design, with arrangements in blocks. The indicators of the phenology and growth of tomato plants were measured. The information was analyzed according to the ANOVA (0.05) and based on the calculated F. Next, the Tukey method (0.5) was applied.Results: the association of aromatic species offers a positive effect on the growth of tomato plants; expressing more noticeable in the flowering stage of aromatic species. The species Tagetes ere cta produced a significant difference with respect to the control and Ocimum basilicum (Tukey 0.05), this suggests that Cempasúchil has some effect on the evaluated variables showing early flowering in the tomato (5 d).Research Limitations/Implications: The plantation interspersed between aromatic species and vegetables generated costs, this can be a limiting factor in the transfer of technology.Findings/Conclusions: The Volatile Organic Compounds of the aromatic species favors the height, the diameter of the stem, the biomass and presents an early flowering (5 d) obtaining an early harvest.
