<![CDATA[Tabia Sala chili pepper (Capsicum chinense var. Tabia Sala) is a local chili cultivar with potential for development through the selection of superior varieties and appropriate fertilization management in lowland areas. This study aimed to determine the effects of two Tabia Sala varieties, five fertilization packages, and their interaction on the growth, physiological characteristics, yield, and fruit characteristics of Tabia Sala chili pepper. The experiment evaluated two varieties, namely Sala 1 (V?) and Sala 2 (V?), combined with five fertilization packages: NPK single 5 g/L (P?), compound NPK 5 g/L (P?), single NPK 5 g/L + Gandasil B 2 g/L (P?), compound NPK 5 g/L + Gandasil B 2 g/L (P?), and AB Mix 5 mL/L (P?). The observed variables included number of leaves, stem diameter, leaf chlorophyll content, relative water content (RWC), days to flowering, days to first harvest, number of fruits per plant, fruit diameter, fruit weight per plant, fruit flesh thickness, number of seeds per fruit, placenta length, placenta weight, and light intensity. The results showed that variety significantly affected several growth, physiological, yield, and fruit characteristics, while fertilization significantly affected several growth, physiological, flowering, yield, and fruit characteristics. The interaction between variety and fertilization was highly significant for relative water content and number of fruits per plant, and significant for days to first harvest, fruit diameter, and placenta weight. Sala 1 combined with single NPK 5 g/L (V?P?) produced the highest number of fruits per plant (55.44 fruits), the largest fruit diameter (6.59 cm), and the highest fruit weight per plant (106.72 g), while also producing the thickest fruit flesh (6.03 mm). AB Mix 5 mL/L (P?) resulted in the earliest flowering (25.40 days after planting), while the earliest first harvest was obtained from the combination of Sala 1 with AB Mix (V?P?) at 11.96 days after flowering. These findings indicate that Sala 1 combined with single NPK 5 g/L is the most promising treatment for increasing yield and several fruit quality characteristics of Tabia Sala chili pepper under the conditions of the study.]]>
