| Summary: | The objective of this study was to evaluate the effect of different organic substrates on the quality of the container-grown S. mahagoni seedling. For this purpose, an experimental trial was carried out in the technified nursery "Camarones", belonging to the Agroforestry Enterprise Baracoa. The substrates used were cocoa husk (Cc), coconut fiber (Fc) and pine sawdust (As) and volumetric mixtures of cocoa husk, coconut fiber and pine sawdust in a completely random experiment with eight treatments and five replicas. The substrates were characterized and the morphological parameters of the seedlings, destubetado characteristics, structural stability of the root ball and radical architecture were determined. The species showed a more favourable morphological response in mixtures Cc60 (Cc-60% + Fc-20% + As-20%) and Cc50 (Cc-50% + Fc-30% + As-20%), attributable to physical and chemical characteristics.
