Приводятся данные по изучению влияния некоторых проведенных агрофитотехнических мероприятий (дополнительной подкормки и поливов) на показатели продуктивности змееголовника. Было установлено, что применение дополнительной подкормки аммиачной селитрой и последующих поливов обеспечивает повышение урожайности сырья на 60%, сбора эфирного масла на 45%, сбора сухого фармацевтического сырья на 53% и составляет 22,5 т/га, 52,2 кг/га и 7 т/га соответственно.

The Moldavian dragonhead (Dracocephalum moldavica L.) is a promising essential oil, spicy and medicinal plant with versatile action, excellent taste and lemon aroma. Nowadays, the Moldavian dragonhead is in demand not only as an essential oil plant, but also as a pharmaceutical raw material, because it is used for of the biologically active additives, phyto teas, being a component of which it has not only a medicinal effect, but also improves the taste; As a component it is found in the recipe of such phyto teas as "Finetea naturii", "Digesti plus", "Baby ceai" and others, produced in Moldova by the company "Doctor Farm". There are presented data on the impact of some agrophytotechnical measures (additional fertilization and irrigation) on the productivity indicators of the dragonhead. The study included the following options of dragonhead cultivation: 1-cultivation under normal conditions - Control; 2-cultivation with additional fertilization N45, without watering in the phase of budding; 3-cultivation with additional fertilization N45 and subsequent 4 waterings on vegetation from the beginning of budding to full bloom. It was found out that application of additional fertilization with ammonium nitrate and subsequent irrigations provides increase of raw material yield by 60%, collection of essential oil by 45%, collection of dry pharmaceutical raw material by 53% and makes 22,5 t/ha, 52,2 kg/ha and 7 t/ha respectively against 13,9 t/ha, kg/ha and 4,5 t/ha in the control version. The raw material met quality standards - it was well foliated, contained a large number of flowers, buds, which gave the raw material its best taste and suitable trade dress. Additional fertilization without further irrigation was not so effective and gave an excess of 21% of raw material yield, 16% of essential oil yield and amounted to 16,9t/ha and 41.6 kg/ha. Collection of pharmaceutical raw materials was at the level of 5.4 t/ha, which is only 17% higher than the control option.
