The study, which was conducted in the Plant Production Department of Agricultural Technical College Northern Technical University sought to demonstrate the effects of bio fertilizers and amino acids on enhancing the growth characteristics and mineral composition of one-year-old Santa Catrina seedlings. Two concentrations of the biofertilizer (Gorabac G) (0 and 10 g plants^-1) were applied once on March 15th, and three levels of amino acids (Tecamin Max commercial fertilizer) (0, 5 and 10 ml l^-1) were applied three times during the season (April 10th, April 30th, and May 20th). The experiment followed the design of an RCBD that had three repetitions of five different seedlings each, which resulted in a total of 90 seedlings. The results demonstrated that the utilization of the biofertilizer at a concentration of 10 g seedling and the amino acid fertilizer at a concentration of 10 ml liter had a significant effect on all vegetative growth indicators, including increased seedling height, diameter, and number. Its leaves and branches increased the efficiency of the mineral content of the leaves of nitrogen, phosphorus and potassium, thusplacing it in a position that surpassed the rest of the treatments and recorded the lowest values in all of the studied traits.
