An Evaluation of the Effectiveness of Moringa (Moringa Oliefera) Leaf Juice Extract as a Foliar Fertilizer and Synthetic Fertilizer on the Growth and Yield of Cabbage (Brassica Oleracea) in Namlombwe Camp of Chilanga District in Lusaka

This study evaluates the effectiveness of Moringa (Moringa oleifera) leaf juice extract as a foliar fertilizer and synthetic fertilizer on the growth and yield of cabbage (Brassica oleracea) in Namalombwe Camp, Chilanga District, Lusaka. The research aims to provide a sustainable and environmentally friendly alternative to conventional synthetic fertilizers. Given the rising costs and environ- mental concerns associated with synthetic fertilizers, Moringa leaf extract is investigated for its potential to enhance cabbage growth, yield, and quality. The experimental design involves randomized complete block design (RCBD) with cabbage plants treated with different concentrations of Moringa leaf extract, synthetic fertilizers, and a control group. Key growth parameters such as plant height, leaf count, and head weight are measured throughout the study. Data are analyzed using SPSS version 25.0, with statistical significance determined through one-way ANOVA and Pearson correlations. The study highlights the importance of sustainable agricultural practices, aiming to reduce the dependence on synthetic fertilizers while ensuring optimal cabbage production. The findings are expected to contribute to the adoption of organic fertilizers and growth promoters in Zambian agriculture, promoting both food security and environmental conservation.
