Kappaphycus alvarezii is the fifth most cultivated macroalgae in the world and has been commercially cultivated in Santa Catarina since 2020. Its cultivation has currently turned to the production of biofertilizers, however, the validation of this product is still a necessity in the sector. Thus, this study aimed to analyze the morphological and biochemical response of using K. alvarezii biofertilizer in basil plants (Ocimum basilicum) cultivated in a hydroponic production system. Using concentrations of 1%, 3%, 5%, and 7%, with weekly foliar application, it was found in the morphological analysis that the biofertilizer at concentrations of 3% and 5% increased the number of nodes, differing from the control. Additionally, the dry matter of the root was also increased when applied at 5%. In the biochemical analysis, an increase was observed in chlorophyll content (1% and 5%), total soluble sugars (5% and 7%), total starch (3%, 5%, and 7%), total carbohydrates (5% and 7%), and total amino acids (5% and 7%) compared to the control. These results indicate that the biofertilizer from K. alvarezii may be a promising alternative for the agricultural sector
