This study evaluated the influence of Ni addition to Hoagland - Arnon nutrient solution on the growth and mineral nutrition of Umbu (Spondias tuberose) tree seedlings. The experiment was in a completely randomized design with four replications and six Ni doses (0; 0.0005; 0.05; 0.1; 0.5; and 1.0 mmol L-1). Low Ni concentrations in the nutrient solution stimulated Umbu seedlings growth. The application of 0.03 mmol L-1 of Ni is recommended for the cultivation of Umbu seedlings in Hoagland - Arnon nutrient solution.
