Abstract

Eggplant (Solanum melongena L.) is a widely consumed vegetable in Indonesia, both as a fresh salad and in various prepared dishes. This vegetable is rich in nutrients, particularly vitamin A and phosphorus, and can help improve the nutritional diversity of the population. In Riau Province, average eggplant productivity has declined, necessitating improvements to the production system to meet steadily rising demand. This study aims to investigate the interaction between earthworm application and cabbage residue and to identify the combination that produces the best eggplant plants. The experiment used a factorial Completely Randomized Design (CRD) with two factors. The first factor was earthworm application (0, 20, and 30 earthworms per polybag). The second factor was cabbage residue application (0, 420 g, and 630 g per polybag). The observed parameters included plant height, days to flowering, days to first harvest, fruit length, fruit diameter, and fruit weight. The data were statistically analyzed using analysis of variance (ANOVA); if the calculated F-value exceeded the table F-value, the analysis continued with Duncan's New Multiple Range Test (DNMRT) at the 5% significance level. The results showed that there was no significant interaction between the two factors for any of the observed parameters. However, individually, the application of 30 earthworms and 630 g of cabbage waste tended to produce the best growth and yield. Based on the research results, it is recommended to use a combination of 30 earthworms and 630 g of cabbage waste.
