 This study aimed to evaluate the initial growth of Mentha piperita L. under the omission of mineral macronutrients. The experiment was carried out in a protected environment, located at the Federal University of Recôncavo da Bahia – UFRB. It was arranged in a completely randomized design (DIC), consisting of 7 treatments, divided into one control with a complete solution, and 6 with individual omission of: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S), for 50 days. The data were collected and subjected to the analysis of variance and the Tukey test at 5% probability. The nutrientes omission interfered with the levels of chlorophyll a, b and total (a + b). The best indexes found were treatments with the calcium omission, the complete solution and the sulfur omission.
