• Abstract: The use of organic fertilizers in agriculture has been increasing and necessary in order not only to offer plants balanced nutrition but also to reuse organic solid waste that could be disposed of inappropriately in the environment. Thus, the objective of this work was to evaluate the agronomic indicators of the R. sativus according to different doses of organic compost in two growing seasons (autumn and spring) in the conditions of the Coastal Tablelands of Brazil. We carried out the experiment in the experimental area at the Federal University of Recôncavo da Bahia (UFRB) from June to July (rainy season) and from October to November (dry season), in both periods arranged in randomized blocks, consisting of five doses of organic compost (0, 5, 10, 15 and 20 t ha-1). Thirty days after sowing, we evaluated: chlorophyll a, b, and total (in the rainy season only), plant height, number of leaves per plant, root diameter, dry and fresh mass of the aerial part and total, and mass and dry and fresh matter of tuberous root. The organic compost stimulated the growth and development of the R. sativus in the two growing seasons. The best agronomic performance of R. sativus was obtained with doses of 15.07 and 20 t ha-1 in the dry and rainy seasons, respectively.
