Resumo
Vegetable organic production has shown steady growth. However, it still needs research at some stages of production, such as fertilization. In the beet crop, information on the organic fertilization in topdressing is scarce. Thus, objective of this study was to evaluate the influence of doses of bokashi applied in top dressing in the production of beet. Two experiments were conducted at the Experimental Farm Sao Manuel (FCA/UNESP), with five rates in topdressing were tested (0, 150, 300, 450 and 600 g m(-2)), and a control with inorganic fertilization in topdressing, using a randomized blocks experimental design, with four replications. In first experiment, the planting fertilization consisted only of organic compost, and, in second one, besides the organic compost was carried out the inorganic fertilization with NPK 4-14-8. The following characteristics were evaluated: plant height, fresh and dry weight of the shoot and the root, root diameter and length, and yield. The application of up to 600 g m(-2) of bokashi in top dressing resulted in an increase in plant height, fresh weight of root, root length and beet yield in both experiments: with and without inorganic fertilizer at planting. The organic fertilization when associated to inorganic presented the best results of the evaluated characters, when compared to organic.
