Agregar Etiqueta | Sumario: | The present research work had the purpose of evaluating the influence of Rhizobium japonicum on the fermentative mass of the hybrid cacao variety. A completely randomized design (DCA) was used, with 3 treatments with their respective control (National), and 4 repetitions. Statistical analysis was performed using the ANOVA analysis of variance, to establish the differences between means, the Tukey test (p≤0.05) was applied. The results achieved in this research were: % test on T3 (R3I0) (15.15) and T6 (I3N0) (15.50); Seed index (I.S.) on T3 (1.40) and T6 (I3N0) (1.46). For fermentation, for the fermented grains the T5 (I2N0) with 77.75% followed by the treatment T6 (I3N0) with 68.50% and T3 (R3I0) with 66.00%, in violet grains the T5 (I2N0) (21.75) and the grains slates with the lowest is T3 (R3I0) (0.50). According to the sensory evaluation, the T6 (I3N0) (27.40%) and T2 (R2I0) (26.03%) stood out since they were selected as those with the best attributes, the most accepted in (aroma, presented lower acidity, a adequate bitterness and highlighting the floral aroma of cocoa) approaching the characteristics of cocoa, said processes were carried out with 10 semi-trained tasters. In T3 (R3I0) (0.36 mg / kg) there was a decrease in cadmium of 0.01 mg / kg and in T6 (I3N0) (0.35mg / kg) of 0.002 mg / kg according to T1 (R1I0) and T4 (I4N0) (0.37 mg / kg) evaluated without the addition of Rhizobium japonicum. An economic analysis was carried out showing variability in the treatments due to the formulations used, resulting in that the treatment has a higher cost in the application of 5% and the treatment with the application of 3%.
