Lactuca sativa is a widely distributed oleracea species, commonly used in various Western and Asian cuisines. This study aimed to evaluate the initial development of L. sativa cv. Psique by applying different concentrations of the commercial biostimulant and bioactivator Vitakelp (mL/L-1) and assessing total fresh weight, total dry mass, root length, and aerial part length of seedlings in two foliar application periods. In the first application, increases were observed in total fresh mass, total dry mass, and aerial part length. In the second application, positive increments were found in total dry mass and aerial part length. The commercial product Vitakelp showed good improvements in the initial development of Lactuca sativa seedlings at different concentrations, especially between 2-6 mL/L-1.
