Зернобобовые культуры — главный источник растительного белка в мире, а в Российской Федерации таким является горох посевной. В технологии возделывания сортов этой культуры, особенно в новых районах, важная роль в формировании высокой урожайности принадлежит установлению оптимальных сроков посева и нормы высева. В связи с этим цель полевого опыта состояла в установлении оптимального сочетания у перспективных сортов гороха посевного норм высева и сроков посева для получения наибольшей урожайности зерна.</p></sec><sec><title>Методы</title><p>Методы. Эмпирические исследования представлены полевыми наблюдениями, учетами и анализами, направленными на реализацию поставленной цели полевого эксперимента.</p></sec><sec><title>Результаты</title><p>Результаты. В результате исследований выявлено влияние изучаемых факторов на густоту посевов, ростовые процессы, фотосинтетическую деятельность посевов, урожайность и адаптивность перспективных сортов. Наибольшее влияние на структуру урожайности зерна гороха оказали сроки посева. При посеве в 1 декаде марта возрастает масса зерна с одного растения, обусловленная увеличением числа бобов. Отмечена обратная корреляционная зависимость между нормой высева и массой зерна с одного растения и числа бобов. Комбинирование самого раннего срока посева и средней нормы высева (1,4 млн шт/га) обеспечивает получение сортами селекции ФИЦ «Немчиновка» Немчиновский 50 и Немчиновский 100 урожая на уровне 5 т/га, однако сорт Немчиновский 50 обладает лучшими показателями адаптивности к конкретным почвенно-климатическим условиям, так как, по результатам комплексного рейтинга, имеет наименьшую сумму баллов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Leguminous crops are the main source of plant protein in the world, and in the Russian Federation this is sown peas. In the technology of cultivars of this crop, especially in new cultivation areas, an important role in the formation of high yields is played by the establishment of optimal sowing dates and sowing rates. Therefore, the purpose of the field experiment was to determine the most effective combination of sowing dates and sowing rates, which ensures the highest yield of promising varieties of sown peas.</p></sec><sec><title>Methods</title><p>Methods. Empirical studies are represented by field observations, surveys and analyses aimed at realizing the goal of the field experiment.</p></sec><sec><title>Results</title><p>Results. As a result of research, the influence of the studied factors on the density of crops, growth processes, photosynthetic activity of crops, yield and adaptability of promising varieties was revealed. It was established that the timing of sowing had the greatest impact on the yield structure of pea grain. When sowing in the 1st decade of March, the mass of grain from one plant increases, mainly due to an increase in the number of beans. The inverse correlation between the seeding rate and the grain weight from one plant and the number of beans was noted. The combination of the earliest sowing period and the average sowing rate (1.4 million pcs./ha) ensures that the selection varieties of the Nemchinovka Federal Research Center Nemchinovsky 50 and Nemchinovsky 100 harvest at the level of 5 tons/ha, however, the Nemchinovsky 50 variety has the best adaptability to specific soil and climatic conditions, since it has the lowest score according to the results of the comprehensive rating </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>горох</kwd><kwd>сорта</kwd><kwd>сроки посева</kwd><kwd>нормы высева</kwd><kwd>урожайность</kwd><kwd>структура урожайности</kwd><kwd>адаптивность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>peas</kwd><kwd>varieties</kwd><kwd>sowing time</kwd><kwd>sowing rates</kwd><kwd>yield</kwd><kwd>yield structure</kwd><kwd>adaptability</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Цахуева Ф.П., Алемсетова Г.К.
