The varied parameters were the irradiation modes: frequency (Hz), magnetic induction (mT), exposure time (min).</p> <p><bold>RESULTS:</bold> An increase in the yield rate of the irradiated industrial batches of grain seeds compared with the non-irradiated ones up to 22% was found, while an increase in laboratory germination up to 17%, field germination up to 10%, germination density up to 10%, plant density before harvesting up to 11% were found.</p> <p><bold>CONCLUSIONS</bold><italic>:</italic> The effectiveness of the irradiation modes of industrial seed masses has been proven by an increase in yield rate for the following varieties: 16 Hz, 25 mT, 25 min — for the Ester spring wheat varieties (an increase of 13%); 50 Hz, 25 mT, 25 min — for the Znatny spring barley (an increase of 5%); 75 Hz, 25 mT, 5 min — for the Povolzhskaya 21 winter wheat varieties (increase of 22%); 16 Hz, 10 mT, 25 min — for the Povolzhskaya Niva winter wheat (increase of 19%), Moskovskaya 39 (increase of 13%).</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Проведённые лабораторные исследования влияния низкочастотного магнитного поля на показатели продуктивности семян зерновых культур выявили стимулирование биофизических и биохимических свойств семян, увеличение их всхожести, энергии прорастания и рост растений, что соответствует плану научных исследований Федеральной научно-технической программы развития селекции и семеноводства зерновых культур до 2030 года.</p> <p><bold>Цель работы</bold> — изучить влияние низкочастотного электромагнитного поля на показатели продуктивности промышленной партии семян зерновых культур.</p> <p><bold>Материалы и методы.</bold> Исследования проводились в соответствии с ГОСТ на опытном образце оборудования для электромагнитного воздействия на 11 сортах зерновых культур по 5 показателям продуктивности: лабораторной всхожести, полевой всхожести, густоте всходов, густоте растений перед уборкой, урожайностью. Варьируемыми параметрами являлись режимы облучения: частота (Гц), магнитная индукция (мТл), время воздействия (мин).</p> <p><bold>Результаты.</bold> Установлено повышение урожайности облучённых промышленных партий семян зерновых культур по сравнению с необлучёнными до 22%, при этом установлено повышение лабораторной всхожести до 17%, полевой всхожести до 10%, густоты всходов до 10%, густоты растений перед уборкой до 11%.</p> <p><bold>Заключение.</bold> Эффективность режимов облучения промышленных масс семян доказана приростом урожайности для следующих сортов: 16 Гц, 25 мТл, 25 мин — для сортов яровой пшеницы Эстер (прирост 13%); 50 Гц, 25 мТл, 25 мин — для ярового ячменя Знатный (прирост 5%); 75 Гц, 25 мТл, 5 мин — для сортов озимой пшеницы Поволжская 21 (прирост 22%); 16 Гц, 10 мТл, 25 мин — для озимой пшеницы Поволжская Нива (прирост 19%), Московская 39 (прирост 13%).</p></trans-abstract><kwd-group xml:lang="en"><kwd>low-frequency electromagnetic field</kwd><kwd>industrial batch of seeds</kwd><kwd>seed treatment</kwd><kwd>yield</kwd><kwd>germination</kwd><kwd>plant density</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>низкочастотное электромагнитное поле</kwd><kwd>промышленная партия семян</kwd><kwd>обработка семян</kwd><kwd>урожайность</kwd><kwd>всхожесть</kwd><kwd>густота растений</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>075-15-2022-1210</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Levina NS, Tertyshnaya YuV, Bidey IA, et al.
