Relevance. Dill is a popular food and medicinal crop (Anethum graveolens L.) of the Celery family (Apiaceae). Seeds of dill are included in the 14th edition of the State Pharmacopoeia of the Russian Federation. However, this crop is characterized by a relatively low yield, which reduces the efficiency of its production. The use of environmentally friendly growth-regulating compounds can significantly increase the yield and improve its quality. As a growth-regulating, foliar treatment with a solution of the amino acid glycine was tested. The amino acid glycine is environmentally friendly and does not pose a danger to humans and animals. The aim of the work was to increase the productivity of garden dill using foliar treatments with glycine amino acid.Materials and methods. Dill varieties Gribovsky and Symphony were chosen as objects to study the effect of the foliar treatments with glycine. Sowing of seeds was carried out at an early date, which for the conditions of the Lipetsk region corresponds to the first decade of April, with a SZT-3.6 seeder with 15 cm row spacing. The seeding rate was 15 kg/ha, the seeding depth was 1-2 cm. were Treatment with glycine solution was achieved in plants rosette phase. The concentration of glycine was 25, 50 and 100 mg / l. The control plants were sprayed with distilled water. The crop was cut during the period of brown seeds on the central umbrella. The content of essential oil was determined by the 14th edition of the State Pharmacopoeia of the Russian Federation (method 1). The content of the main components was determined by gas chromatography.Results. As a result of the research, a positive effect of foliar treatments with glycine on both yield and the content of essential oil in the raw material of dill varieties Gribovsky and Symphony was revealed. As a result of treatments, regardless of concentration, the seeds yield and the yield of essential oil per unit area increased. The increase in the mass of 1000 pieces of fruits was not unambiguous. Based on the results obtained, the effective concentration of amino acid glycine 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 prior to harvesting, different aspects of the drug's action appear. According to the results of observations for 2 years and an assessment by the sum of the indicators, the optimal concentration of glycine in most cases was 100 mg / l, at the same time, for the Symphony variety for two years, two-foliar treatment with low concentrations of glycine (10 mg / l rosette + 10 mg / l budding).

Укроп огородный (Anethum graveolens L.) является востребованной пищевой и лекарственной культурой , но его урожайность относительно низкая Применение экологически безопасных рострегулирующих соединений позволяет существенно повысить урожай и улучшить его качество. Испытана эффективность некорневой обработки безопасным для человека и окружающей среды раствором аминокислоты глицин. Действие препарата изучали на сортах укропа огородного Грибовский и Симфония, которые возделывают на семена и зелень соответственно. Опыты проводили в Липецкой обл. в 2019 и 2020 гг. Посев проводили в ранние сроки (1-я декада апреля), сеялкой СЗТ-3,6 с междурядьями 15 см. Норма высева составляла 15 кг/га, глубина заделки семян – 1-2 см. Обработку растений раствором глицина в концентрациях 25, 50 и 100 мг/л проводили в фазе розетки. Контрольные посевы опрыскивали дистиллированной водой. Срезку проводили в период побурения семян на центральном зонтике. Содержание эфирного масла определяли методом гидродщистиляции, компонентный состав - методом газовой хроматографии. Выявлено положительное влияние внекорневых обработок глицином как на урожайность (достигавшую 11-15 ц/га у сорта Грибовский и 8-10 ц/га у сорта Симфония), так и на содержание эфирного масла в сырье (4-5% при минимальном требовании фармакопейной статьи 2%). В результате обработок независимо от концентрации повышалась урожайность и выход эфирного масла с единицы площади. Увеличение массы 1000 штук плодов было не однозначным. Исходя из полученных результатов, эффективная концентрация препарата определяется не только особенностями сорта, но и погодными условиями. По результатам наблюдений в течение 2 лет и оценке результата по сумме показателей оптимальная концентрация глицина для сорта Грибовский составила 100 мг/л, а для сорта Симфония в более эффективной была двукратная обработка раствором глицина с низкими концентрациями (10 мг/л в фазу розетки + 10 мг/л в фазу бутонизации). | Dill (Anethum graveolens L.) is a popular food and medicinal crop, but its yield is relatively low. The use of environmentally friendly growth-regulating compounds can significantly increase the yield and improve its quality. The efficiency of foliar treatment a human and environmentally friendly amino acid glycine solution was tested. The effect of the preparation was studied on dill varieties 'Gribovsky' and 'Symphony', which are cultivated for seeds and greens, respectively. The experiments were carried out in the Lipetsk region in 2019 and 2020. Sowing was carried out at an early date (the 1st decade of April), with a SZT-3.6 seeder with 15 cm row spacing. The seeding rate was 15 kg/ha, the seeding depth was 1-2 cm. Treatment with glycine solution in concentrations of 25, 50 и 100 mg/l was carried out in the rosette phase. The control plants were sprayed with distilled water. The crop was cut during the period of brown seeds on the central umbrella. The content of essential oil was determined by hydrodistillation. The content of the main components was determined by gas chromatography. A positive effect of foliar treatments with glycine on both yield (achieved 11-15 dt/ha in the variety 'Gribovsky' and 8-10 dt/ha in the variety 'Symphony') and the content of essential oil in the raw material (4-5% wity minimal requirement of pharmacopoeial item of 2%) was revealed. As a result of treatments, regardless of concentration, the seeds yield and the yield of essential oil per unit area increased. The increase in the mass of 1000 pieces of fruits was not unambiguous. Based on the results obtained, the effective concentration of amino acid glycine is determined not only by the characteristics of the variety, but also by weather conditions. According to the results of observations for 2 years and an assessment by the sum of the indicators the optimal concentration of glycine was 100 mg/l for the Gribovsky variety, two-foliar treatment with a glycine solution with low concentrations (10 mg/l in the rosette phase + 10 mg/l in the budding phase) was more effective for the Symphony variety.
