Chemical Characteristics and Plant Growth Regulators of Organic Waste as Liquid Organic Fertilizer

Abstract

Abundant agricultural waste could be used to improve plant growth. This study was to obtain the nutrient characteristics and plant growth regulators (PGR) of organic waste (eggshells, banana peels, moringa leaves, onion peels, bean sprouts, and banana hump) which have the potential as liquid organic fertilizer (LOF). This research was conducted from July to August 2022 using a descriptive-analytic method. Organic waste was fermented anaerobically. The results showed that nitrogen content in banana peels, moringa leaves, onion peels, bean sprouts, and banana hump required the LOF standard (3-6%) and had the potential to be applied. In addition, eggshells had the highest calcium content (0.149%) compared to other organic wastes. Among the organic wastes, it was found that banana hump, moringa leaves, and onion peels had the highest PGR levels.
