Effects Of Macronutrient Fertilization On Plant Growth, Essential Oil Content, And Chemical Composition In Medicinal And Aromatic Plants Grown Under Different Environmental Conditions: A Review

Abstract

The rates of macro-elements in the soil under different environmental conditions is one of the most investigated aspects of medicinal plants research worldwide. In cultivating vegetative crops, applying high rates of macronutrient fertilization increased plant growth and vegetative yield, but when the cultivation goal was growing medicinal and aromatic plant for large quantities of high-quality essential oils, the outcomes of macronutrient fertilization may vary dramatically. Macronutrient fertilization has been applied and its influence studied in detail for many medicinal and aromatic plants grown under different environmental systems. Based on the results of previous studies, it can be concluded that applying adequate levels of macronutrient fertilization, foliar and split applications, increases essential oil content and components for several medicinal and aromatic plants. The present review also revealed that it helps medicinal and aromatic producers increase the yield of essential oil and other secondary metabolites used in different commercial and industrial productions. Moreover, this review also presents important information for reducing environmental pollution, which is particularly important in developed and developing countries
