Abstract

The use of environmentally friendly fertilizers is increasingly needed to support sustainable agricultural production. Cow urine and landfill leachate contain essential nutrients that can be utilized as raw materials for liquid organic fertilizer. This study aimed to evaluate the effectiveness of liquid organic fertilizer derived from cow urine and leachate on the growth of pakcoy (Brassica rapa L.) and to determine the most effective application concentration. The experiment was conducted in the Greenhouse of Universitas Negeri Medan using a Completely Randomized Design (CRD) with four treatments, namely P0 (control), P1 (10%), P2 (20%), and P3 (30%), each with three replications. Plant height and number of leaves were observed for 21 days. The results showed that the application of liquid organic fertilizer significantly increased plant height compared with the control treatment. The highest plant height was obtained in treatment P2 (20%) with an average of 9.50 cm, followed by P3 (30%) and P1 (10%). In contrast, the treatments did not significantly affect the number of leaves. The findings indicate that nutrients contained in cow urine and leachate were able to support vegetative growth, particularly plant height. Therefore, a concentration of 20% is recommended as the optimum treatment for improving pakcoy growth. Keywords : growth performance, nutrient availability, organic waste utilization, sustainable agriculture, vegetative growth
