| description | Nursery fertilization is a cultural practice with potential to improve seedling quality, but it is necessary to define adequate fertilization levels for each specie. This study evaluated the effect of fertilization levels on seedling quality of Pithecellobium dulce during the nursery stage. The applicated levels were nine; they consisted in regimes in which a controlled-release fertilizer (CRF) 18-6-12, in three doses (4 g L-1, 6 g L-1, and 8 g L-1 of substrate) was mixed with a water-soluble fertilizer (WSF) 20-20-20, in concentrations of nitrogen of 0 mg L-1, 75 mg L-1, and 150 mg L-1. The fertilization regimes effects were determined by assessing morphological attributes of seedling quality, net assimilation rates (NAR), and nutrimental status of N-P-K on four-month old seedlings. A seedling-quality test was designed to undergo the seedlings to a stress condition of both nutrient’s deficiencies and biomass loss, thereby measuring their resprouting capacity and growth. Statistical differences were observed by the effects of the fertilization regimes. Overall, an increase of the morphological quality and NAR was promoted by the mix of 8 g of CRF with 150 mg N L-1 of WSF, although the main responses in relation to the nutrimental status were of deficiency and dilution. In the seedling-quality test, the seedlings had limitations to induce either their resprouting or their growth according to the amount of nutrimental reserves. The fertilization with CRF and WSF have potential to enhance the seedling quality of P. dulce during nursery culture. |

La fertilización en vivero es una práctica cultural con potencial para mejorar la calidad de planta, pero es necesario definir niveles de fertilización adecuados para cada especie. Este estudio evaluó el efecto de niveles de fertilización en la calidad de planta de Pithecellobium dulce, durante la etapa de vivero. Los niveles aplicados fueron nueve; consistieron en regímenes en los que se combinó un fertilizante de liberación controlada (FLC) 18-6-12, en tres dosis (4 g L-1, 6 g L-1 y 8 g L-1 de sustrato) con un fertilizante hidrosoluble (FHS) 20-20-20, en concentraciones de nitrógeno de 0 mg L-1, 75 mg L-1 y 150 mg L-1. El efecto de los regímenes de fertilización se determinó analizando índices morfológicos de calidad, tasas de asimilación neta (TAN) y estado nutrimental N-P-K en plantas de cuatro meses de edad. Una prueba de calidad fue diseñada para someter a las plantas a estrés en una condición de escasa fertilidad y pérdida de biomasa aérea, para evaluar capacidad de rebrote y crecimiento. Hubo diferencias estadísticas por efecto de los regímenes de fertilización. En general, la combinación de 8 g de FLC con 150 mg de nitrógeno por litro del FHS propició un incremento en la calidad morfológica y en la TAN de las plantas, aunque nutrimentalmente las respuestas principales fueron de suficiencia y dilución. En la prueba de calidad, las plantas tuvieron limitaciones para favorecer su rebrote o crecimiento según la cantidad de reservas nutrimentales. La fertilización con FLC y FHS tiene potencial para incrementar la calidad de planta de P. dulce en vivero.
