Cabbage yield as a function of bokashi doses

Due to the lack of information on the response of cabbage (Brassica oleracea var. capitata) to bokashi type organic compounds, the present work was developed to evaluate the effect of different doses of bokashi (0.0, 5.0, 7.5, 10.0 and 12.5 t ha(-1)) on their development and productivity. A field trial was carried out in the conditions of Seropedica, RJ, from May to August, 2017. The hybrid Sekai I F1 was used. The compost was applied in the planting pits (50%) and in a cover fertilization (50%), at 38 days after transplanting (DAT). A randomized complete block design was used, with four replications. The plants were harvested at 75 DAT where the following variables were obtained: longitudinal (LD) and transverse diameter of head (TD), in cm, fresh head mass (FHM) in kg, and estimated productivity (t ha(-1)). Data were submitted to analysis of variance and regression at 5% of probability. A quadratic effect of bokashi doses was observed on all analyzed variables. The best bokashi dose was 10.0 t ha(-1) , resulting in the highest mean values for LD (12.31 cm), TD (19.09 cm), FHM (1.96 kg) and maximum productivity (32.63 t ha(-1)). It was concluded that the compound positively stimulated the vegetative development of plants by raising their productivity.
