The demand for biofuels in the world is growing and some crops have presented great potential for producing raw material for biodiesel production. The objective of this study was to evaluate the feasibility of the use of sewage sludge associated with ecogypsum for crambe cultivation. The experiment was conducted in a greenhouse and the sludge was applied in the non-composted and composted form. The statistical design was completely randomized in a factorial scheme 5 x 2 + 2: five doses of sewage sludge (0 t ha-1, 5 t ha-1, 10 t ha-1, 15 t ha-1, 20 t ha-1), two ecogypsum (calcitic and dolomitic) based on the content of soil clay and its pH and two additional treatments (conventional fertilization with calcitic ecogypsum and with dolomite ecogypsum). Phytotechnical characteristics were valuated: plant height, collar diameter, seed dry weight, aerial parts dry weight, and seed oil content. It was observed that fertilization with sludge produced significant results in the development of Crambe plants. The best performance of the plants occurred with the dose of 13 t ha-1 of sewage sludge associated with application of ecogypsum for the cultivation of Crambe abysinica.
