Enhancing growth and productivity of medicinal and aromatic plants using natural plant growth promoters such as moringa (Moringa oleifera, Lam.) has recently gained wide attention. However, there are no elaborate reports on the impact of Moringa Leaf Extract (MLE) as growth promoter in mint crop. This study was conducted to investigate the effect of Moringa Leaf Extract (MLE) on growth, herb yield and essential oil content in Mentha arvensis L. var. Kosi. Foliar application with MLE at 1%, 2% and 3% concentration on plants were compared with the control (water spray). Results revealed that all the crop-growth parameters were significantly improved as compared to the control. Interestingly, not only essential oil content but also the marker compounds especially menthol and isomenthone, were also increased. Among applied treatments, foliar application of 2% MLE was the most effective in improving the crop performance. This treatment enhanced the menthol content in the oil up to 6.3% in comparison to control. Conclusively, the current study suggests that MLE may be used as a promising natural growth enhancer to improve productivity of Mentha arvensis.
