MENDIVIL-LUGO, Cecilia et al. Elaboration of an organic fertilizer type bocashi and its evaluation on germination and growth of radish. Biotecnia [online]. 2020, vol.22, n.1, pp.17-23.  Epub Aug 03, 2020. ISSN 1665-1456.  https://doi.org/10.18633/biotecnia.v22i1.1120.

The present study consisted in the elaboration of a bocashi and the evaluation of its effects on germination and development of radish. The mixtures of bocashi were: saw dust-mangoose-banana (BA), mangoose (BM) and traditional (BT). For physicochemical characterization, 1 kg of each bocashi was taken. To evaluate emergence of radish seeds, an essay was realized in polystyrene trays with a mixture of bocashi - peat moss (1:1 v/v), in triplicate. The reference was agricultural soil (A). To evaluate the effect on plant quality, plants were transplanted to wooden organoponic tables, with a mixture of bocashi - peat moss (1:1 v/v). The irrigation was daily for a month. After thirty days of transplant, we measured: plant height (cm), number of leaves and root dry biomass (g). Treatment A promoted the higher germination of radish seeds; as to the plant development, treatment A stimulated the height and leaves number of radish plant; but nevertheless, treatment BT favored the greater accumulation of dry biomass. The radish plants fertilized with bocashi showed better development than those germinated in agricultural soil.
