Biochar (charcoal) is the term given to biomass subjected to the process of decomposition or change in the composition by the action of heat at high temperatures. The potential use of biochar as a soil amendment to mitigate the stress induced by salt in the plant has received little attention. This study aimed to evaluate the effects of biochar in the development of crambe irrigated with saline waters. The experiment was carried out in a greenhouse, following a completely randomized design with five levels of biochar and two irrigation waters, with four replications, totaling 40 experimental units. The analyzed parameters of plants were height, shoot and grain weight. Crambe growth was decreased as an effect of the doses of biochar used in this study. The electric conductivity of the waters used in this experiment did not caused influence in the analyzed parameters.
