Leucaena seedlings, due to its nature as an arboreal plant, and the capacity it develops for the symbiotic fixation of nitrogen, the producer does not consider fertilization plans in these species, however it is a considerably viable practice in the first phenological phase of the plant, basically because in this way a vigorous seedling would be obtained and in good physiological conditions for its transplant and/or development in the field directly.
▶ In this sense, the stimulation of seedling growth obtained through the use of bioproducts is a way to obtain excellent quality seedlings; biofertilizers or biological fertilizers are based on microorganisms that promote and benefit plant nutrition and growth.

From this point of view, a sustainable and environmentally friendly agriculture could be generated by providing an important alternative to limit the use of chemical fertilizers, reducing their negative environmental and economic impact and improving crop productivity.
Currently in the local market, there are organic products formulated from earthworm humus, bovine manure and shrimp exoskeletons, which have been promoted as growth stimulants, so it is important to study their effect on the behavior of this species.
Through organic fertilization of the seedlings under controlled conditions, in order to ensure the survival of the seedlings, counteract competition and have healthy, strong and vigorous seedlings, essential at the time of transplanting them to the field.
