Coriander is the leading essential oil crop and occupies vast areas, both in our country and abroad, and is be used to produce linalool, with subsequent processing into other aromatic substances. Increasing its yield and quality of raw materials with the help of modern preparations is an urgent problem of essential oil production.Purpose of the work: increasing the productivity of coriander with combined use of foliar treatments with glycine and auxin-containing preparations for directed control production process in coriander seed.Material and methods. As objects for studying the effect of the drug, varieties of coriander sowing Yantar and Avangard were chosen. Plants were sown in the first or third decade of April, depending on the conditions of the year, using a SZT-3.6 seeder with row spacing of 15 cm. The seeding rate was 25 kg/ha, the seeding depth was 2 cm. concentration 10 mg/l. Drug concentrations: IAA-glycol phosphate – 25, 50 and 100 mg/l, DvaU - 2 ml/l. Treatment with a solution of IUKGF and DvaU was carried out in the phase of budding-beginning of flowering. The cutting was carried out during the period of browning of seeds on the central umbrella. The content of essential oil was determined according to SP XIV method 1.Results. As a result of the research, a positive effect of foliar treatments with glycine was revealed, both on the yield and on the content of essential oil in the raw material of coriander seed varieties Yantar and Avangard. Based on the results obtained, the effective concentration of the drug is determined not only by the characteristics of the variety, but also by weather conditions, when, depending on the conditions during the processing period and the previous harvest, different aspects of the drug action appear. The maximum increase in the collection of essential oil of coriander variety Yantar (11.1 kg/ha) was noted during the combined treatment of plants with glycine at a rate of 10 mg/l in the leaf rosette phase and IAA-GF at a rate of 50 mg/l in the budding phase; varieties Avangard (8.6 kg/ha) - with combined treatment of plants with glycine at a rate of 10 mg/l in the leaf rosette phase and DvaU at a rate of 2 ml/l in the budding phase.
