The objective of this work was to evaluate the effect of different organic fertilization levels on the production of marigolds (Calendula officinalis L.) planted on living perennial mulch of Bahia grass (Paspalum notatum). The experiment was carried out in Montes Claros, on a Cambisol, in an experimental design of randomized blocks with four treatments (0, 3, 6 and 9kg of organic fertilizer m-2) and six replications. The addition of organic fertilizer increased the capitula dry matter mass linearly.
