Conteúdo:	This study evaluated the agronomic efficiency of bokashi-type fermented compost, formulated with brewery residue (RC), wheat bran (FT) and castor bean meal (FM), in the production of single-head broccoli under organic management conditions. Two field trials were conducted in Baixada Fluminense, Rio de Janeiro, considering three cultivars (Legacy, Veratto and Coliseu) and five doses of fermented compost (0, 100, 200, 300 and 400 kg/ha of ). The experiment was conducted in a randomized complete block design with a split-plot arrangement and four replications. The results showed differences in the performance of the cultivars according to the fertilizer doses and climatic conditions. The cultivars Veratto and Legacy stood out in terms of yield, reaching the highest yields at the dose of 400 kg of N ha⁻¹, whereas Coliseu showed a linear dose-response. The use of compost was effective in meeting the crop’s nutritional requirements, promoting yield levels consistent with commercial standards, despite adverse weather conditions that influenced the development pattern of the cultivars.
