The present work aimed to evaluate the response of sesame to salt stress during germination and initial growth. The design was completely randomized with a multifactorial scheme of 2x3x3, Factor A variety K2 and IPTA K07, Factor B (doses of 0, 3g. L-1 and 6g. L-1 of salt and Factor C immersion time of 0, 12 and 24 hours, with 18 treatments and 4 repetitions, totaling 72 experimental units. The determinations evaluated were hydration capacity, emergence speed (VE), aerial and root length of the plant and germination percentage. For the hydration capacity of the plant the (T3) obtained optimal results; while for the dose of solution used the results were statistically equal to each other. A favorable relationship was recorded with (T1) for the interaction AxB. The determination of emergence speed obtained better results with the control. Regarding the aerial length of the plant the (T16) obtained better results, not so with the determination of root length where no significant differences were found. For the interaction AxB and BxC obtained better interaction for the determination of aerial length (T1). The K2 variety obtained 93% germination, with the other factors being statistically equal to each other. It is concluded that the K2 variety obtained better results in most of the determinations evaluated.
