The thesis of the researcher (Safa Shanan Hachem) included the treatment of mint with three concentrations of humic acid (2,1,0) g.l and three concentrations of seaweed extract (2,1,0) mg.l. The study aims to identify the effect of humic acid and seaweed extract on vegetative growth, oil yield and active ingredients in mint leaves. The study concluded that treatment with humic acid at a concentration of 2 g.L led to a significant increase in most of the vegetative growth indicators, chemical characteristics, oil yield and the active compounds of the oil and did not differ much with a concentration of 1 g.L. The treatment with seaweed extract at a concentration of 2 mg.L also led to a significant increase in Some indicators of vegetative growth, chemical, oil yield and active compounds. The letter recommended the use of lion humic and seaweed on the rest of the vegetables.
