Liming and Phosphating in Dalbergia nigra (Vell.) Allemão ex Benth. Seedlings

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

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.
