Efektivitas Pemberian Pupuk Organik Cair Berbasis Limbah Organik Terhadap Pertumbuhan Bayam Hijau (Amaranthus hybridus)
Abstract
The utilization of organic waste as liquid organic fertilizer (LOF) is an alternative approach to support sustainable agriculture and reduce dependence on inorganic fertilizers. This study aimed to analyze the effect of LOF derived from kepok banana peels, pineapple peels, lamtoro leaves, and eggshells on the growth of green spinach (Amaranthus hybridus L.). The experiment was conducted using an experimental design with four treatments, namely control (without LOF), LOF at concentrations of 15%, 20%, and 25%. The observed parameters included plant height and number of leaves. Data were analyzed using the Shapiro–Wilk normality test, Levene’s homogeneity test, and one-way ANOVA at a 5% significance level. The results showed that LOF application had a significant effect on the number of leaves (p < 0.05), while plant height exhibited an increasing trend but was not statistically significant. The 25% LOF treatment resulted in the highest average growth, with a plant height of 7.17 cm and an average of 6.67 leaves, which was higher than the control. The improvement in plant growth was associated with the availability of macro-nutrients, particularly nitrogen and potassium, which support vegetative tissue development. Therefore, LOF derived from organic waste has the potential to be utilized as an environmentally friendly alternative fertilizer to enhance the growth of green spinach.
