Nitrogen fertilizers are widely used in agricultural fields to improve crop production. The main objective of the present study was to investigate the effect of nitrogen levels on the quantity and quality of essential oils present in plants of Mentha longifolia, Mentha microphyta and Ocimum basilicum. It was found that these plants had a maximum content of essential oils when 200 kg nitrogen fertilizer was used per hectare. The composition of the essential oil in the tested plant species also differed significantly. The results suggest that the use of nitrogen fertilizers may increase the production of essential oils in plants. The results indicated that the use of nitrogen fertilizers also improves the quality of the essential oils produced in the plants.

Key words: Oil essential quality, essential oil composition, biosynthetic pathway, basil, mint, antimicrobial activity.
