| Abstract: | Le Moringa oleifera, reconnu pour ses vertus nutritionnelles et médicinales, est également utilisé comme stimulant de croissance végétale grâce à sa richesse en nutriments et antioxydants. Cette étude examine l’efficacité de l’extrait de Moringa oleifera appliqué par pulvérisation et par irrigation sur la croissance du blé et de la luzerne, deux espèces couramment cultivées. L'objectif était de comparer les effets de deux modes d'application de l'extrait de Moringa oleifera—pulvérisation et irrigation—sur la surface foliaire, le volume racinaire, ainsi que les rapports de matière sèche et fraîche racinaire/aérienne des deux plantes. Nous avons cherché à déterminer l’impact de ces traitements sur la croissance aérienne et racinaire et leur efficacité en tant qu’activateur de croissance |
| Description: | Moringa Oleifera, well known for its nutritional and medicinal virtues, is also used as a plant growth stimulant thanks to its richness in nutrients and antioxidants. This study examines the efficacy of Moringa Oleifera extract applied by spraying and irrigation on the growth of wheat and alfalfa, two commonly cultivated species. The aim was to compare the effects of two modes of Moringa Oleifera extract application-spraying and irrigation-on leaf area, root volume, and root/air dry matter and fresh matter ratios of the two plants. We sought to determine the impact of these treatments on aerial and root growth and their efficacy as growth activators. Spray application led to a significant increase in leaf area for both wheat and alfalfa, indicating better direct uptake of nutrients by the leaves. However, for root volume, spraying showed a more marked effect on wheat, while irrigation had a slightly greater effect for alfalfa. Analyses of dry and fresh matter revealed that spraying favored aerial growth to the detriment of root development, while irrigation maintained a balance closer to that observed in the absence of treatment. Soluble sugar content also increased under spraying, especially for wheat, suggesting a better response to the nutrients supplied. Alfalfa, although showing an improvement under spraying, presented overall lower soluble sugar levels. Moringa Oleifera extract is an effective growth activator, with distinct effects depending on the mode of application and species. Spraying is optimal for aerial growth, while irrigation is preferable for root development, especially for alfalfa. These results underline the importance of tailoring treatments to specific plant needs to maximize benefits. |
