The research was conducted in the nursery of the National Intercultural University of Amazonia, whose objective was to use effective microorganisms with plant protection ceramics in the initial growth of Theobroma cacao, "common cocoa". The experiment was conducted through a completely randomized design (DCA), with 5 treatments, 10 repetitions and 50 experimental units. The treatments were: T1 (Control); T2 (100 ml of efficient microorganisms (EM) + 20 g of phytoprotective ceramic (CF)); T3 (200 ml of MS + 20 g of CF); T4 (300 ml of EM + 20 g of CF) and T5 (400 ml of EM + 20 g of CF). As a result, the T3 treatment obtained better growth value in height, diameter and specific leaf area with: 25.56 cm, 6.86 mm and 90.77 cm2 / g respectively, compared to the control that reached 19.98 cm. 5.49 mm. 49.32. Regarding the quality indexes, the ratio of aerial dry biomass / dry root biomass (R BSA / RBSR), lignification index (IL), robustness index (IR) and Dickson quality index (DQI), did not show significant differences between the treatments, but the T3 had higher value over the IR with 3.76, the R BSA / RBSR with 2.45 and DQI with 0.85, and the T4 had greater value in the IL with 33.68.
