Abstract

This study aimed to evaluate the effect of liquid organic fertilizer (LOF) derived from rabbit urine on the growth and yield of several eggplant (Solanum melongena L.) varieties. The experiment was conducted at the Greenhouse of the Faculty of Agriculture, Warmadewa University, from March to November 2025, using a factorial randomized block design with treatments consisting of LOF doses (50–200 ml) and eggplant varieties. Observed parameters included plant height, number of leaves, number of flowers, number of fruits, as well as fresh and dry fruit weight. The results showed that LOF application significantly affected all variables, with the 50 ml + 6 g salt treatment on the green eggplant variety producing the highest growth and yield. These findings highlight the potential of rabbit urine-based LOF as an eco-friendly alternative to improve eggplant productivity.
