Application of Moringa leaf extract as a seed Priming agent on Seed germination

Commercial growth enhancers have proven to be highly effective in promoting the growth and development of crop plants, especially under the challenging conditions associated with chilling stress. These enhancers are often costly and may not always be easily accessible to all farmers. In this regard, the leaves of Moringa oleifera L. present a noteworthy alternative. Rich in various beneficial compounds, such as zeatin, ascorbate, phenolic compounds, calcium, and potassium, Moringa leaves provide a natural solution for enhancing crop growth. This study aims to explore the growth-promoting effects of Moringa oleifera L. leaf extract, specifically focusing on its impact on the germination rates of Allium cepa L. and Abelmoschus esculentus L. To evaluate these effects, different concentrations of Moringa leaf extracts—25%, 50%, 75%, and 100%—were systematically applied and compared to a control group that received distilled water. The results demonstrate that the aqueous extracts of Moringa oleifera L. significantly enhance seed germination and positively influence various growth parameters, including shoot length and root length. Furthermore, the vigour index of the tested species shows considerable improvement. Notably, the growth-enhancing effects become more pronounced at higher concentrations of Moringa oleifera L. This study emphasises the significant differences in concentration levels and their complex interactions concerning the specific growth parameters investigated, highlighting the potential of Moringa oleifera L. as an effective and accessible growth enhancer for crops.
