An experiment was carried out to evaluate the effect of different sources and doses of nitrogen and Rhizobium inoculation on the production of sesbânia seedlings (Sesbania virgata). The substrate was decomposed sugarcane bagasse + filter cake (3:2; v:v). The statistical design was a 3 x 3 x 2 factorial scheme (3N doses - 100, 200 and 300 mg/dm³ x 3 N sources - urea, ammonium sulfate and ammonium nitrate + two additional treatments - with and without Rhizobium inoculation. The experiment was arranged in a randomized complete design, with three replicates. Each experimental plot was composed of 80 seedlings. Height, diameter, shoot and root dry matter weights, leaf area and root regeneration potential of the seedlings were evaluated. It was concluded that, for this substrate, sesbânia seedlings can be produced without the addition of nitrogen fertilizers.
