| Zusammenfassung: | In this study, the biometric parameters and the percentage of endophytic colonization of the fungus Trichoderma spp. in cocoa plants at the nursery stage were evaluated. A completely randomized experimental design was used, employing two organic mineral fertilizers (Agrohúmicos Plus and Agrodol) and the fungus Trichoderma (TrichoVita product composed of Trichoderma asperellum and T. virens), provided by the companies PROMIVECA and TecnoVita. Each fertilizer was evaluated separately and in combination with the fungus, resulting in eight treatments, including a control. The results showed that there were no significant differences in biometric parameters among the treatments studied; however, they fell within the ranges reported in previous studies, highlighting a trend of improvement in plants treated with Agrodol and Trichoderma during pre-germination compared to the control. The physicochemical parameters of the substrate were within expected ranges according to various authors, reflecting adequate conditions for cocoa plant growth. Regarding endophytic colonization, 50 % of the treatments exhibited a symbiotic relationship with the fungus Trichoderma. |
