A factorial experiment was conducted in the nursery unit of Aliko Dangote University of Science and Technology, Wudil. The experiment combined three pre-sowing treatments (hot water, acid, scarification, and control) with two sowing depths (1 cm and 2 cm). The results indicated that the interaction between pre-sowing treatment and sowing depth had a significant effect on seedling growth parameters, including leaf production, plant height, and stem girth. Notably, the study found that the acid treatment at a 2 cm sowing depth (B2) consistently resulted in the highest leaf production (9.867), plant height (13.70 cm), and stem girth (1.980 mm) at 8 weeks after sowing. The hot water treatment at the same depth (A2) also produced promising results, particularly in leaf production (9.200) and plant height (13.63 cm). These findings contradict previous reports suggesting that concentrated H2SO4 and mechanical scarification treatments were more effective, emphasizing the importance of seed quality variability, treatment duration, and concentration. This research contributes to developing effective procedures for producing high-quality Tamarindusindica seedlings, thereby facilitating efficient and widespread plantation establishment. It is recommended that the acid treatment and 2 cm sowing depth be adopted for optimal seedling growth and development
