Abstract: Anthropogenic changes in land use have led to significant loss of vegetation globally, causing a biodiversity crisis through habitat destruction. This issue is acute in biomes like the Caatinga, characterized by low rainfall, high temperatures, and nitrogen-poor soils. Addressing this degradation requires multifaceted strategies, including changing human behaviors and adopting silvicultural techniques such as nitrogen fertilization. Prosopis juliflora, adapted to semi-arid conditions, is a promising species for rehabilitating this biome. This study investigated the impact of varying nitrate levels on the initial growth of P. juliflora seedlings, using a randomized design with nitrate concentrations ranging from 0.0 to 10.0 mmol dm-3. Measurements of seedling height, stem diameter, and biomass were taken periodically up to 55 days after sowing. Findings reveal that high nitrate levels do not enhance P. juliflora seedling growth, with optimal concentrations between 3.5 and 6.5 mmol dm-3. P. juliflora's adaptability to infertile soils makes it a cost-effective and sustainable choice for restoring the Caatinga. Further research is recommended to refine these findings and improve reforestation practices, ensuring the species' full potential is utilized.
