The present research investigates the influence of organic and chemical fertilization on the essential oil yield and phenolic composition of Dracocephalum moldavica L., commonly known as dragonhead, and the effect of 3-month storage on the dried aerial parts of the plant. The primary objective was to evaluate how different fertilization practices affect the production of essential oils and phenolic compounds, which are essential for the plant's medicinal properties. The research also examined the impact of storage duration on the preservation of these bioactive compounds, a critical factor for the commercial viability of D. moldavica as a medicinal herb. Organic fertilization, with its potential for sustainability, and chemical fertilization, known for its high nutrient delivery, were compared to assess their influence on the plant’s biochemical composition. The storage experiment focused on understanding how prolonged storage could alter the stability of essential oils and phenolics, which are prone to degradation. This research aims to provide insights into optimizing agricultural practices for the production of D. moldavica with high-quality essential oils and phenolic content, which could enhance its use in pharmaceuticals and food products. Statistical analyses were performed to determine the significance of fertilization types and storage time on the chemical profile of the plant. Results revealed that organic fertilization enhanced the phenolic composition and essential oil yield more effectively than chemical fertilization. Furthermore, the 3-month storage period significantly reduced the concentration of volatile compounds, suggesting the need for optimized post-harvest handling. This research provides valuable information for both organic and conventional growers of D. moldavica and those involved in the production of natural health products.
