Abstract
The use of vegetable biostimulants as an agronomic technique to optimize the production of seedlings has been used in crop management, this makes it possible to obtain plants with higher quality in less time nursery. This study aimed to evaluate the effects of Stimulate® bio stimulant, in the early development of passion fruit plants 'BRS Rubi Cerrado'. The experiment was carried out in a nursery with 50% shading, a randomized complete block design with subdivided plots. The plots correspond to the doses of Stimulate® (30, 60, 90, 120 and 150 mL L-1) and the control, and the sub-plots for the evaluation periods (0, 15, 30, 45 and 60 days after application of the product). Sprays were made at 0, 7, 14 and 21 days after transplantation of the seedlings for plastic bags. The product was diluted with water and the corresponding control plants was applied only water. The length of stem and largest root, stem diameter, number of leaves, leaf area, specific leaf area, leaf area ratio, leaves, stem and root dry weight, and SPAD index were evaluated. Data were submitted to analysis of variance and regression, at 1 and 5% probability levels. The use of the Stimulate® biostimulant, promoted inhibition of the growth of passion fruit cv. BRS Rubi do Cerrado and the effect of the doses does not differ according to the days after the application of the product.
