    The tomato is a food consumed worldwide, it is known that it represents 30% of the world's horticultural production is this; Likewise, at the national level its consumption is in large quantities, so its production in the country has been increasing, however, one of the most common problems is fruit set in the flowering stage, decreasing production if external conditions or internal are not favorable for fruit set, the flowers drop after anthesis and even after pollination, so it is important to improve its performance. The objective of this study was to test three bioregulators Cytoquin®, New Gibb and Brasinolide, in different doses when applied in open flower and closed flower, it was carried out in the Paute canton, Secay sector, an area that is known for the tomato production. The results show that in all the variables both in open and closed flower there were significant differences (p-value < 0.05). It was evidenced that there is a tendency to obtain better results of some variables when applying the bioregulators in closed flower. The application of New Gibb in concentrations of 1250 mg/l in closed flower obtained the best performance, however, it deformed the fruit. The best bioregulator in diameter was Brasinolide at a dose of 0.0625 mg/l in a closed flower. Brasinolide 0.0625 mg/L was the best bioregulator applied in closed flower, it allowed to obtain greater weight, while in yield, Brasinolide 0.0625 mg/L in closed flower and Cytoquin 2.25 ml/L in open flower obtained very similar results. This research suggests that it is better to apply the bioregulators in closed flower as it allows the fruit to have better characteristics and is a starting point for further research in this phenological stage of the plant.
