Within the sowing period, the maximum height is achieved by plants that receive intensive irrigation. Slightly lower indicators were recorded in moderate irrigation and almost half as low in plants with natural moisture. The highest yield of aboveground mass in all species was noted in the intensive irrigation variant. However, the essential oil content within the sowing periods is highest in the natural moisture variant: in Moldavian snakehead – 0.15%, in garden savory – 0.50%, in ciliated alsholtsia – 0.25% of freshly harvested raw materials. It was determined that the highest yield of essential oil from one plant during the second sowing period in the moderate irrigation variant: in the Moldavian snakehead – 0.50 g, in the garden savory – 0.78 g, in the ciliated elsholtsia – 0.58 g. According to the research results, a database of indicators of niche essential oil crops was developed and filled with data from field research in 2025. Mathematical models were created that allow determining the amount of essential oil yield depending on the yield of the aboveground mass. The CROPGRO model from the DSSAT package was adapted for the types of essential oil crops under consideration. The potential possibility of using the Moldavian snakehead model as part of information systems was shown. Product Description popup.authors Knysh Vladyslav V.
