<![CDATA[The productivity of red chili pepper (Capsicum annuum L.) continues to face various challenges, particularly due to declining soil fertility and the high dependence on inorganic fertilizers, which may have adverse environmental impacts. One promising alternative is the use of moringa leaf extract (Moringa oleifera Lam.) as a natural biostimulant rich in nutrients and growth-promoting compounds. This study aimed to analyze the effect of moringa leaf extract application on the growth of red chili pepper plants based on plant height, number of leaves, and stem diameter. The research employed a true experimental design using a Completely Randomized Design (CRD) consisting of seven treatments: P0 (0 mL), P1 (10 mL), P2 (20 mL), P3 (30 mL), P4 (40 mL), P5 (50 mL), and P6 (60 mL), each replicated five times. Data were analyzed using normality and homogeneity tests, One-Way ANOVA, and the Least Significant Difference (LSD) post hoc test at a 5% significance level. The results indicated that all data were normally distributed and homogeneous. ANOVA analysis revealed that moringa leaf extract application had a significant effect on plant height (p = 0.046), number of leaves (p = 0.044), and stem diameter (p = 0.037). The P6 treatment (60 mL) produced the best growth performance, with an average plant height of 13.20 cm, 10.40 leaves, and a stem diameter of 0.72 cm. These findings suggest that moringa leaf extract has considerable potential as a natural organic fertilizer alternative to enhance the vegetative growth of red chili pepper plants in a sustainable manner.]]>
