The cultivation of medicinal plants in the ecological system is a topical topic, with an increasing emphasis. The society is aware that products of plant origin that are not subjected to an industrialization process and are used directly in food and therapy should be free of chemical residues (chemical fertilizers, pesticides). The two plants studied are important for the aromatic and spicy role they have in the food alimentation, but also for the antiseptic capacity given by linalool (basil) and carvacrol (thyme). The study synthesizes a series of biometric and physiological determinations that highlight the productivity of herba mass and volatile oil. Planting was done at a distance of 70 cm between rows and 35 cm respectively 28 plants between rows. Harvesting of plants for the determination was done in full bloom. The obtained results show that for the variety with the highest foliar surface the volatile oil content is significant, of 2.4 ml / kg, and the highest quantity of herba was obtained for the variety with the most branches. The drying efficiency was 1: 2.1 for Lemon and Vert and 1: 1.7.
