Abstract

This study evaluated the effects of Trichoderma sp., chicken manure, and their interaction on the growth and yield of purple eggplant (Solanum melongena L.). The experiment was conducted in Medan Deli, North Sumatra, Indonesia, from December 2024 to March 2025 using a factorial Randomized Block Design with three replications. The first factor was Trichoderma sp. at 0, 10, and 20 mL/polybag, while the second factor was chicken manure at 0, 500, and 1,000 g/polybag. Observed variables included plant height, stem diameter, number of leaves, flowering age, total fruit number, fruit weight per plant, root length, and root weight. Data were analyzed by analysis of variance and significant effects were separated using Duncan's Multiple Range Test at 5%. Trichoderma significantly affected plant height at 2, 6, and 8 weeks after planting and root length, with the 20 mL/polybag treatment producing the highest values for these responses. Chicken manure significantly affected plant height at 2 weeks and stem diameter at 8 weeks. The interaction between the two factors significantly affected plant height at 8 weeks and stem diameter at 4, 6, and 8 weeks. Most yield-related variables were not significantly affected. Overall, the treatments were more consistently associated with vegetative growth than with fruit production.
