Peppers (Capsicum spp.) have stood out in the food, medicinal, and ornamental sectors in Brazil and worldwide for more than 500 years. One of the most widely adopted management practices in recent years has been the use of bioproducts, which bring ecological appeal, ease of management, and cost-effectiveness to both small and large producers. Plant growth promoters, or biostimulants, establish a mutualistic relationship between bacteria and plants. Seed treatment with biostimulants and their application during the early developmental stages of peppers using Stimulate promote root growth, aid in germination, and induce resistance to abiotic conditions. Demonstrating the efficacy of these products is essential to support reliable technical recommendations for farmers. In this context, the objective of the present study was to evaluate the physiological quality of seedlings of Capsicum frutescens L. var. pirâmide, treated with plant growth-promoting bacteria under different application methods. The experiment was carried out at the experimental area of the Federal University of Pampa (UNIPAMPA), Itaqui/RS campus. Ornamental pepper seedlings were produced on-site, and a randomized block design was adopted, with seven replications and three treatments. The treatments consisted of: a control; a treatment with growth-promoting bacteria applied directly to the substrate after seedling emergence; and a treatment in which growth-promoting bacteria were applied before sowing as a seed treatment. The method of applying plant growth-promoting bacteria had significant effects on the physiological growth of Capsicum frutescens L. seedlings. Overall, when the biostimulant was applied as a seed treatment, it promoted greater seedling development, resulting in larger shoot and root systems.
