Abstract

This study investigated the effects of liquid organic fertilizer (LOF) derived from tofu wastewater enriched with organic nitrogen (N), phosphorus (P), and potassium (K) on the growth and yield of green bean (Phaseolus vulgaris L.) plants. The research was conducted from June to August 2024 on farmers’ land in Noekele, Tuatuka Subdistrict, Kupang Regency, East Nusa Tenggara Province, Indonesia. A Randomized Complete Block Design (RCBD) was employed, consisting of six LOF concentration treatments: 0% (control), 5%, 10%, 15%, 20%, and 25%, each replicated four times. Data were analyzed using analysis of variance (ANOVA), and significant differences among treatments were further examined using the Honest Significant Difference (HSD) test at a 5% significance level. The results showed that the 5% LOF concentration had the most significant positive effect. At six weeks after planting, this treatment resulted in the tallest plants (191.12 cm), the highest number of pods per plant (23.75), the longest pods (16.14 cm), the greatest pod weight per plant (238.52 g), and the highest average pod weight (10.04 g). These findings suggest that applying LOF from tofu wastewater enriched with organic N, P, and K at a 5% concentration can significantly enhance green bean growth and productivity. Keywords: green bean, tofu wastewater, liquid organic fertilizer (LOF), organic nutrients, plant growth, yield
