Production of Saladette-type Tomato (Solanum lycopersicum L.) in response to the association with aromatic species

Objective: This study analyzes tomato production in response to Volatile Organic Compounds (VOCs) emitted by the foliage and flowers of Ocimum basilicum, Tagetes erecta, and Origanum majorana, intercropped with the vegetable. Design/methodology/approach: The development of tomato and aromatic plant species (Ocimum basilicum¹, Tagetes erecta², and Origanum majorana³) was evaluated during both vegetative and flowering stages. Treatments were distributed using a completely randomized block design. Indicators of tomato fruit production and quality were measured and analyzed. Results: The associations with aromatic plants emitted VOCs based on alkaloids, glycosides, and terpenes, which act as stress regulators and enhancers of tomato plant growth and yield. This demonstrates the importance of aromatic species in improving the quality and size of tomato fruits. Limitations of the study/implications: During the course of the research, challenges related to VOCs (aroma) arose, as they are difficult to control between experimental units and treatments. The use of 2-meter polyester nylon barriers between treatments prevented the exchange and leakage of VOCs. Findings/conclusions: The association of aromatic plants with tomato affected fruit yield and quality indicators, resulting in higher production per plant and better fruit quality compared to the control.
