This study aimed to verify the effect of phosphorus and liming doses on the morphological and nutritional characteristics of D. nigra seedlings. The experiment was conducted using a completely randomized 4x4 factorial design. The treatments consisted of 4 levels of liming and 4 phosphorus doses. Morphological characteristics and nutritional analyses of plants were measured. There were no significant interactions between liming x P. Morphological characteristics presented differences for liming and phosphorus when analyzed separately. The best productive performances were found between an increase in base saturation between 48.07% and 54.76%. Morphological characteristics showed a linear behavior for P. Both the application of liming and P promoted positive effects on D. nigra growth.
