Исследования проводились в лесостепи Восточной Сибири в 2018–2019 годах. Для создания сортов гороха (Pisum sativum L.) с высокой кормовой продуктивностью необходимо включать в селекционный процесс листочковые формы вместо более технологичных усатых сортов. Цель исследования — анализ коллекции гороха листочкового морфотипа для селекции на кормовые цели. Материалом для исследования послужили 20 образцов гороха листочкового морфотипа. Образцы оценивали по укосной и зерновой продуктивности. Погодные условия в годы проведения исследований отличались от среднемноголетних значений: 2018 год был очень засушливым (ГТК — 0,60), 2019 год — засушливым (ГТК — 0,89). Урожайность зависела от биологических особенностей сорта и погодных условий годов исследований. Следует отметить высокую продуктивность сорта гороха полевого Интенсивный 92: в оба года он попал в верхнюю часть ранжированного списка, превысив стандарт. В среднем по урожайности зелёной массы сорт Интенсивный 92 превосходил стандарт Радомир на 3,40 т/га, по урожайности семян — сорт Орпела на 0,10 т/га. Рентабельность производства зелёной массы сорта Интенсивный 92 оказалась на 53,7% выше стандарта. По рентабельности производства зерна сорт Орпела превысил стандарт на 8,8%. Выделены источники важных хозяйственных признаков: для селекции на увеличение урожайности семян — горох полевой Орпела; урожайности зелёной массы — сорта Апостол и Интенсивный 92; в качестве источника семенной продуктивности растений — сорта Тюменский кормовой, Шал, Орпела; устойчивости к полеганию — Альбенс и Орпела; устойчивости к аскохитозу и тле — Clause и Id 29200910. The investigation took place in the forest-steppe of the Eastern Siberia in 2018–2019. To create pea (Pisum sativum L.) varieties with high feed productivity, it is necessary to include leafy forms in a breeding process instead of leafless varieties suitable for machine harvesting. The research aimed at screening a collection of leafy peas for breeding feed varieties. 20 leafy varieties were analyzed according to their green mass and grain productivity. Weather conditions differed from the long-term average values: 2018 was very dry (hydrothermal index = 0.60), 2019 — dry (hydrothermal index = 0.89). Productivity depended on plant biology and meteorological conditions. Pea variety “Intensivny 92” showed high productivity ; it hit the top of the ranked list, exceeding the standard in both years. “Intensivny 92” exceeded the standard “Radomir” in green mass yield by 3.40 t ha-1 and“Orpela” — in grain productivity by 0.10 t ha-1. The profitability of green mass production of “Intensivny 92” was 53.7% higher than the standard. The profitability of “Orpela” grain production exceeded the standard by 8.8%. The sources of economically important traits were found: field pea “Orpela” — to increase grain yield; “Apostol” and “Intensivny 92” — for high green mass yield; “Tyumenskiy kormovoy”, “Shal”, “Orpela” — high seed productivity; “Albens” and “Orpela” — lodging resistance; Clause and Id 29200910 — resistance to Ascochyta leaf spot and aphids.

The article presents findings of the influence of different levels of mineral nutrition on plant growth and development, the impact of fertilizers on the botanical composition, on the productivity and forage benefits of cereal-bean agrocenoses in the forest-steppe zone of the Baikal region. The objects of research were mixed crops of oats with peas and millet with vetch, peas, and Austrian winter pea. Legumes are the main source of protein increase in feed. In the field, the most widespread, among legumes, were vetch, sowing peas, field peas (Austrian winter pea). As a result of phenological observations, it was found that the growth and development of plants depended on the biological characteristics of crops, weather conditions and directly on the mineral nutrition level. The millet reacted most effectively to the application of mineral fertilizers, starting from the exit phase into the tube. The introduction of mineral fertilizers in pre-sowing tillage contributed to an increase in the proportion of legume components in the total green mass yield and a decrease in cereals. The highest competition in agrocenoses of millet with legume components was vetch, its share in the mixture increased, compared to the unfertilized background, by 6 and 14.5%, depending on the background of fertilizers. It was found that, compared with the unfertilized background, mineral fertilizers increased the yield of green mass from 1.5 to 4.9 tons per hectare, the collection of dry matter from 0.4 to 2.0 tons per hectare and the collection of feed units from 0.3 to 1.3 tons per hectare. Digestible protein content in 1 unit increased with the introduction of nitrogen fertilizer (N45), depending on the type of components in the mixture, from 3.2 to 6.6 g, and with the introduction of complex mineral fertilizer (N45P30K30) from 2.5 to 9.6 g. All are millet-bean mixtures at all levels of mineral nutrition comply with zootechnical standards.

Полевые опыты проведены в 2017–2020 годах на опытном поле кафедры растениеводства и плодоовощеводства Красноярского государственного аграрного университета в УНПК «Борский» (Сухобузимский район Красноярского края), расположенном в лесостепной зоне. Посев многолетних бобовых трав был проведён в 2017 году. Люцерну гибридную высевали с нормами 5, 10, 15 и 20 кг/га, клевер луговой — с нормами высева 5, 10 и 15 кг/га. Контрольными были нормы высева, рекомендованные в лесостепной зоне Сибири для люцерны гибридной и клевера лугового, — 15 кг/га. Учёты урожайности зелёной массы проведены фазу цветения в 2018–2020 годах. Целью работы являлось определение эффективности производства кормов из люцерны гибридной и клевера лугового при различных нормах высева. Доля влияния нормы высева на урожайность зелёной массы люцерны гибридной составляла 25,8%, клевера лугового — 10,6%. Самый высокий вклад в рост урожайности зелёной массы вносило взаимодействие факторов «норма высева × год». Регулирование нормы высева при любых погодных условиях приводило к высокой реализации адаптивного потенциала многолетних бобовых трав и повышению урожайности зелёной массы. Максимальная урожайность зелёной массы люцерны гибридной получена при высеве с нормой 5 кг/га, клевера лугового — при 15 кг/га. Производство кормов из люцерны гибридной и клевера лугового при всех исследуемых нормах высева являлось рентабельным и экономически эффективным. Использование многолетних бобовых трав для производства зелёной массы при нормах высева, показавших максимальную урожайность, позволило снизить затраты на производство кормов за счёт роста урожайности и снижения себестоимости в сравнении с прочими исследуемыми нормами высева. Лучшей нормой высева люцерны гибридной с экономической точки зрения была норма 5 кг/га с рентабельностью 212,2%, клевера лугового — контрольная норма высева (15 кг/га) с рентабельностью 93,2% The field trial took place at the Department of Crop, Fruit and Vegetable Production of the Krasnoyarsk State Agrarian University in 2017–2020. Perennial legume grasses were planted in 2017. Seeding rates of hybrid alfalfa were 5, 10, 15 and 20 kg ha-1, red clover — 5, 10 and 15 kg ha-1. Seeding rates recommended for Siberian forest-steppe were considered as standard — 15 kg ha-1. Green mass yield was calculated at flowering stage in 2018–2020. The research aimed at testing the effectiveness of forage production from alfalfa and clover under various seeding rates. Only 25.8% of alfalfa productivity and 10.6% of clover yield resulted from the effect of seeding rate. Seeding rate–year interaction had the highest impact on green mass production. Optimization of seeding rate led to higher crop adaptability and green mass yield regardless of weather conditions. The highest green mass productivity of alfalfa happened under the seeding rate of 5 kg ha-1, red clover — 15 kg ha-1. Fodder production from both hybrid alfalfa and clover was economically effective regardless of seeding rate. Perennial legume grasses decreased costs for feed production due to their yield increase and lower prime costs under the most effective seeding rates. The alfalfa seeding rate of 5 kg ha-1 was the most profitable, the payback amounted to 212.2%. Seeding 15 kg ha-1 of red clover resulted in payback of 93.2%

The paper highlights the results of agroecological experiments on 11 varieties of winter triticale. The experiments were conducted in the steppe climate zone of thePrimorskTerritoryin 2017-2018. The research aims at identifying the best varieties of fodder and grain forage, which are characterized by high productivity of green mass and grain with valuable economic features. Extreme weather conditions observed during the research period contributed to exploration of the crop response to bad environmental factors. Winter triticale winterhardiness was 0.3-2.1 points on average for varieties. The green mass decreased by 69% due to freezing. The researchers observed the highest prospective green mass yield (28.6-35.7 t/ha) in the following varieties: Tyumenskaya zernokormovaya, Zimogor, Kornet, which significantly exceeded the winter rye Spasskaya mestnaya productivity by 6.3-13.4 t/ha. The crop yield of these varieties was stable and changed insignificantly by 2.6-3.4 t/ha. The experiment revealed Agraf and Tornado varieties that contributed to the highest yield of digestible protein - 5.9 c/ha and available energy - 69.3-66.7 GJ/ha, exceeding the indicators of winter rye by 2 c/ha and 16.6-19.2 GJ/ ha. The authors claim the prospective variety is Tyumenskaya zernokormovaya, which had the highest yield of dry substance and available energy - 7.5 t / ha and 85.5 GJ / ha. These parameters were higher than those of the standard grain and productivity was by 0.5 tons / ha higher. This variety can compete with winter rye for fodder purposes. The winter triticale is a crop for risky cultivation in this climate zone. It can grow in the areas with high snow cover.
