The article presents an assessment of the productivity and quality of oilseeds of the Asteraceae family in the agro-climatic conditions of the forest-steppe of the Middle Volga region. The object of the research: safflower (Carthamus tinctorius), milk thistle (Silybum marianum), guizotia (Guizotia abyssinica). Insufficient amount of precipitation was observed during the growing season of 2019 (Selyaninov Hydrothermal Coefficient (HTC) – 0.68). In 2020, a moderate precipitation deficiency was observed during the growing season (166.9 mm); year was characterized as arid (HTC 0.78). The growing season 2018 was severely arid (HTC 0.34). The length of the safflower growing season during the monitoring years was 108–121 days, guizotia — 111–130 days, milk thistle — from 111 to 117 days. The number of developed flower heads per one safflower plant was 15.3, guizotia – 112.5, milk thistle – 7.5. The productivity of one plant varied from 9.2 to 19.2 g; the coefficient of variation (CV) was 8.1–29.3 %.1000-seed weight did not vary significantly; CV ranged from 2.5 (guizotia) to 7.3 % (milk thistle). All crops in the forest-steppe of the Middle Volga region formed a high yield of oilseeds (0.88–1.68 t/ha) with oil content up to 24.51–40.62 % and were characterized as highly drought tolerant (62.1–71.3 %). Guizotia abyssinica provided a high yield of seeds (1.54–1.68 t/ha) and a significant content of oil in them (40.62 %). The drought-tolerant coefficient (DC) was 68.5 %. Carthamus tinctorius is an amazing drought tolerant plant; DC – 71.3 %. On average, its seed yield amounted to 1.37 t/ha; oil content – 24.51 %. Content of oleic acid in Silybum marianum oil was high (29.43 %), seed oil content – up to 29.31 %, seed productivity – 0.70–0.88 t/ha. In general, these crops combine high oilseeds’ productivity and quality and are of interest for introduction in the forest-steppe of the Middle Volga region.

Целью исследований являлась оценка урожайных свойств и основных параметров адаптивности сортов сафлора красильного в агроклиматических условиях лесостепи Среднего Поволжья. Исследования проводили в 2017-2019 гг. на опытном поле Пензенского института сельского хозяйства. Объектом исследований являлись шесть сортов сафлора красильного. Метеорологические условия периода вегетации характеризовались как засушливые, где гидротермический коэффициент (ГТК) колебался от 0,4 до 0,82 единиц. Индекс условий среды варьировал в пределах от - 0,61 до 0,13 единиц. Наиболее оптимальные условия для развития культуры сложились в 2019 году (Ii – 0,13), где сформировалась наиболее высокая урожайность семян по всем сортам 1,34-1,53 т/га. Высокий урожай отмечен у сортов Заволжский 1 и Александрит, продуктивность которых составила 1,37 и 1,42 т/га, соответственно. Коэффициент изменчивости урожайности составил 6,58-14,19 %. Низкая вариация урожая по годам отмечена у сортов Ершовский 4 и Астрахансий 747 (6,58-7,71 %), что говорит об их стабильности. У данных сортов был наиболее высокий показатель уровня стабильности сорта (ПУСС) и составил 0,26 и 0,22 соответственно. Сорта Заволжский 1, Астраханский 747 и Александрит сформировали крупные семена, масса 1000 семян их достигала в среднем 41,4-41,6 г. Содержание жира в семянках колебалась в пределах 23,70-27,45 %. В условиях Пензенской области лучшими по экологической адаптивности были сорта Заволжский 1 и Александрит, параметры адаптивности которых составили bi = 0,99-1,01; σdr2 = 0,09. Наиболее высокие значения индекса стабильности (0,17 и 0,20) имели сорта Александрит и Ершовский 4, что показывает их большую приспособленность к конкретным условиям. The purpose of the research was to evaluate the yield properties and the main parameters of adaptability of safflower (Carthamus tinctorius) varieties in the agricultural climatic conditions of forest-steppe of the Middle Volga Region. The research was conducted in 2017-2019 on the experimental field of the Federal Scientific Center of Bast Crops. The object of research was the six varieties of safflower (Carthamus tinctorius). Meteorological conditions of the growing season can be characterized as dry; the hydrothermal coefficient (HTC) ranged from 0.4 to 0.82 units.

The results of the study of 250 collection samples of spring soft wheat of various ecological and geographical groups are presented in order to identify the source material that combines optimal plant height and high productivity for the conditions of the forest-steppe zone of the Middle Volga region. The work was carried out in 2017–2020 in the Samara region. The study and evaluation of samples was carried out according to the Methodology of the state variety testing and the methodological recommendations of the VIR. The average height of plants in the samples over the years of research varied within 68.5-109.2 cm, the coefficient of variation of the trait was 11.86-13.72 %. The presence of a positive average and weak correlation between the yield and plant height, regardless of the moisture conditions of the year (r = 0.15-0.47), was revealed. A strong positive relationship was observed between the height of the samples and the following weather factors: precipitation in June (r = 0.94), precipitation during the growing season (r = 0.87), hydrothermal coefficient of June (r = 0.93), hydrothermal coefficient for the growing season (r = 0.83). The highest grain yield was formed by samples from the group of undersized and medium-grown, on average 416 and 428 g/m2, respectively. A number of highly productive varieties were identified: 3 medium-grown samples (105 cm) with a yield of 419.7-435.7 g/m2 and 21 undersized samples (85-102 cm) with an average grain yield of 485.0-585.7 g/m2. Dwarf specimens sample a stable manifestation of short-stemmed growth over the years and high resistance to lodging were noted. According to the research results, it was found that the optimal height of plants for the forest-steppe zone of the Middle Volga region is in the range of 85-105 cm. The selected undersized and medium-grown samples with high grain yield and dwarf samples with high resistance to lodging are recommended for use in breeding programs of the region and places with similar conditions.

The work presents the results of studies for 2017-2019, aimed at developing methods for increasing the productivity of sunflower hybrids cultivated according to the Clearfield system when using the microfertilizing mixture Agromineral in the forest-steppe zone of Middle Volga region. The results of the studies showed that the safety of plants at the time of harvesting is up to 91.8%; the maximum safety is achieved when processing crops by vegetation with Agromineral microfertilizing mixture at a dose of 3 l/ha. The leaf area increased until the budding phase, reaching a maximum of 99.2 thousand m2/ha, on a mid-season hybrid when processing crops with a dose of 3 l/ha, and then, due to drying of the lower leaves, it begins to decrease to the phase of the onset of flowering to 37.8 ... 57.9 thousand m2/ha. The maximum value of the photosynthetic potential is formed by crops of the mid-season hybrid 8N477KLDM - 4.781 million m2/ha days. The use of fertilizers and micronutrient mixtures increases its value and, as a result, increases productivity by 9.09 ... 9.36 kg/ha with an absolute indicator of 27.2 ... 33.2 kg/ha.
