Abstract
Chili pepper (Capsicum frutescens L.) is a high-value horticultural commodity, but its productivity is often hampered by the excessive use of chemical fertilizers. This study aimed to evaluate the effect of planting medium composition and plant growth-promoting rhizobacteria (PGPR) concentration on the growth and yield of chili pepper. The study was conducted from May to August 2025 at the Kedungrejo Seed Garden, Madiun Regency, using a factorial Randomized Block Design (RAK) with two factors: planting medium (soil, soil + compost, soil + manure, and soil + compost + manure) and PGPR concentration (0, 8, 16, and 24 ml/L), each replicated three times. Significant interactions were found between planting medium and PGPR on plant height, number of leaves, and fruit weight. The combination of soil + manure with PGPR at doses of 8 and 16 ml/L produced the highest values for fruit weight (up to 2.99 g) and number of leaves (44). Soil and manure alone also increased root weight and fruit number while accelerating flowering. PGPR at a dose of 16 ml/L significantly increased shoot dry weight and shortened the harvest period. This study demonstrates that combining organic media with PGPR can sustainably increase chili productivity.
