Abstract. The research on studying of influence of the increasing doses of nitrogen fertilizers on growth and development of Agastache rugosa was conducted on the collection site of herbs located in the Beloyarsk district, Sverdlovsk region. The object of this research was the type of Agastache rugose of the essential-oil plants group, possessing valuable medicinal properties. Transplanting method was used in the experiment. Seeding was carried out in the second decade of April. Landing of seedling to the open ground – in the middle of May: distance in a row of 25 cm, width of row-spacings – 50 cm, landing density – 8 plants on m2. The experiment purpose was to study influence of the increasing doses of nitrogen fertilizers on growth and development of Agastache rugosa. Objectives of the experiment included studying of the main aspects of growth and development of plants against the background of the increasing doses of nitrogen fertilizers. The scheme of experience has included 4 options differ- ing on doses of nitrogen fertilizers: 1st option – w/f (without fertilizers – control); 2nd option – N30P30K30; 3rd option – N45P30K30; 4th option – N60P30K30. It is established that development of plants is in close dependence on doses of nitrogen fertilizers: the heavier the dose, the better the development. In the fourth option (N60P30K30) the considerable advancing of plants in growth and development was observed, the average daily gain varied from 0.9 to 2.7 cm. Under the influence of nitrogen fertilizers the quantity, weight, percent of large leaves and inflorescences increases. The best biometric indicators are characteristic of plants in the fourth option (N60P30K30).
