This study aimed to evaluate the effect of the diluted application of Bokashi on seed germination and seedling development of tomato (Solanum lycopersicum) and cucumber (Cucumis sativus). The experiment was conducted in two stages: the first, in the laboratory, analyzed germination with two treatments: T1 (control), irrigated with water, and T2 (Bokashi), with a diluted solution (10 mL L-1 of water). Germination was monitored in a B.O.D. (Biochemical Oxygen Demand) incubator at 25 °C under a 12-hour photoperiod for 9 days. The results showed that Bokashi reduced tomato germination by 17%, but did not affect cucumber germination, which remained 100%. In the second stage, in a greenhouse, the seedlings were transplanted into pots with Ultisol (argissolo) and monitored for 33 days, receiving 150 mL of water daily. Parameters such as height, number of leaves, leaf area, and stem diameter were evaluated weekly, with no significant differences at the end. There were also no changes in physiological parameters (chlorophyll content, stomatal conductance, chlorophyll a transient fluorescence, and pigment content), indicating that Bokashi did not affect these variables. Thus, the results indicate that Bokashi use did not improve germinative performance or seedling development.
