The use of ozonized oil has now become an ecological biostimulant medium that contributes to morphological growth, control of pests, diseases, inactivation of viruses, bacteria and resistance to biotic and abiotic stress, when applied to any type of crop. The present research project was developed in the Juan Montalvo parish, belonging to the Ambato canton, with the purpose of evaluating the morphophysiological effects presented by the cultivation of sunflower (Helianthus annuus), Sunbright hybrid, with the application of four doses of ozonated oil ( Agrozoil) at 3, 5, 7, 10 cc/l, as a foliar applied biostimulant, the study factors that were evaluated were plant height, stem diameter, number of leaves, inflorescence diameter, number of petals, crop cycle, leaf area and dry mass. A completely randomized block design with five treatments and four repetitions was drawn, the application of the product was carried out every 15 days, making four applications. Obtaining as a result that the dose (D4) at 10 cc/l of ozonized oil, influenced the morphological growth of stem diameter with an average greater than 1.46 cm, number of leaves with an average of 13 and 14 leaves, mass dry root with a fresh weight of 29.2 g, stem with a weight of 223.8 g, and inflorescence reaching a weight of 30.58 g, compared to the other doses evaluated, on the other hand the dose (D3 ) at 7 cc/l of ozonated oil, influenced the variables plant height with a stem length of 115.45 cm, diameter of the inflorescence 13.6 cm, leaf area with an average greater than 84.18 cm2 and cycle of the culture reaching a cut-off point at 61 days compared to the other doses.
