ABSTRACTThe study the diet of Eneolithic populations is of great interest to archaeologists. However, the studies undertaken in the steppe and forest-steppe zones of Volga region in Russia have left many issues unsolved. Data collected recently through the comprehensive studies of Lebyazhinka VI settlement enable us to change this situation. Of particular importance at this settlement site is good preservation of animal bones, bone fishing tools, and ceramics of the same type with food crusts and connected to a large house pit. For the first time in this geographical area, bones of domestic animals were found in the fill of a dwelling. The aim of this paper is to present the results obtained through comprehensive studies of diet and economy in the Eneolithic based on the materials from Lebyazhinka III and Lebyazhinka VI settlement sites. The main results of the archaeozoological analysis— determinations of species, age and size of the animals—provide the necessary data for studying the diet. We conclude that there are differences between Lebyazhinka III and Lebyazhinka VI settlements. Lebyazhinka III settlement included bones of only wild species, however, Lebyazhinka VI settlement consists of wild and domestic species.

The work was carried out in 2018-2019 in the forest-steppe zone of Samara region. The purpose of the research is to conduct study samples of collection nursery of various ecological and geographical origins and identify new sources of economically valuable traits for breeding in the forest – steppe of the Middle Volga region. The material for research was 352 collection samples of spring soft wheat, including 108 foreign varieties and hybrids and 244 domestic samples of breeding institutions of the Russian Federation. Meteorological conditions during the research years were quite severe, and vegetation took place in arid and acutely arid conditions (hydrothermal coefficient in 2018 – 0.51, in 2019 – 0.48, with a long-term value in the region of 0.73). The greatest variability over the years of research was observed in the indicators of grain yield of samples (Сv=23.9...27.5 %) and plants height (Сv=10.8...12.9 %). According to the research results, 30 new genetic sources of economically valuable traits of spring soft wheat were identified. Sources of precocity (period of shoots-earing 35...37 days): Uralskaya kukushka, Chelyaba rannyaya, Tyumenskaya 25, Lutescens 70, Odeta, Libertina, Chi Mai, Long Fu 7, M83-1551.

The article presents results of studies of comparative productivity and cultivation economic efficiency of soybeans, peas, lupine and chickpeas, depending on main tillage systems in crop rotation and the level of plant protection from harmful organisms. Grain legumes are capable of forming a seed yield of 2.0 t / ha in the conditions of the forest-steppe zone of the Volga region. Three-year experimental studies have shown that the studied leguminous crops can be arranged in the following row according to the yield level: peas - 2.51 t / ha> lupine - 2.12 t / ha> chickpea –2.11 t / ha> soybean - 2.10 t / ha. Evaluation of the effect of soil tillage in cultivation of grain legumes showed a significant yield increase by plowing for 25-27 cm in comparison with tillage for 12-14 cm for all the studied crops, a yield increase for adaptive-integrated plant protection was also noted in comparison with minimum protection (protection only against weeds). Studies show that lupine crops had an advantage in protein content, its yield is from 533 to 802 kg / ha, as for soybeans, protein yield was 449-666 kg / ha, peas - 430-521 kg / ha, and chickpeas - 346-486 kg / ha with the advantage of the mentioned variants. A higher conditional net income was obtained on soybeans (31555-44584 rubles / ha) and chickpeas (27777-40037 rubles / ha), especially on combined tillage in crop rotation. Plant protection systems had an equal impact on economic efficiency of their cultivation; in some variants, adaptively integrated plant protection was less effective

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.

The article presents the results of the effectiveness studies of No-till technology on chernozem in a typical forest-steppe zone of the Volga region. Research has shown that No-till technology provides water, agrophysical and agrochemical properties of soil that are favourable for plant growth while effectively controlling weeds. There is also a tendency to increase the yield and product quality. According to our estimates, direct sowing increases the yield of spring wheat grain by 0.5 kg/ha, the mass fraction of gluten from 13.6% to 15.0%, the mass fraction of protein from 11.0% to 11.6% in comparison with traditional technology.

The modern development of world farming was announced at the UN Conference on Environment and Development, and is connected with the biosphere paradigm of nature management (1992), which implies the priority of maintaining the ecological functions of soils and landscapes (ecologization). In agriculture, ecologization is known as “organic farming” (ecological, biological, etc.), but in Russia, “organic farming”, in its pure form (without pesticides and chemical fertilizers), has not gained momentum yet. The legislative base for this was developed only in 2019 and in the coming years it is unlikely to receive widespread distribution among representatives of agribusiness for economic, social and cultural reasons. Further development of modern agribusiness is possible due to technological modernization through the technological upgrading by means of a system of biologization. In this article, we have revealed the main factors and practical methods of biologization of modern farming under the conditions of the forest-steppe zone of the Volga region.

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.

Grain Crops

In the conditions of the forest-steppe zone of the Volga region, winter wheat occupies the largest area among grain crops, which is associated with its relatively high productivity, economic efficiency and the ability to unload the peaks of field work in the spring. Winter wheat makes fuller use of the bioclimatic potential of productivity, especially in the arid conditions of the region. Despite the fact that the adaptive-integrated approach to the joint use of agricultural techniques and chemicalization means when growing grain crops provides significant and stable yield increases, they require regular study to adjust agricultural technologies. The article presents the results of 3-year studies in a stationary field experiment to assess the influence of predecessors, methods of basic soil cultivation and plant protection on the spread of diseases and weeds, as well as on the yield of winter wheat. Studies have shown that the placement of winter wheat after clean fallow helps to reduce the infestation of crops, and after cruciferous predecessors (white mustard, spring rape)— the spread of root rot (Bipolaris sorokiniana (Helmintosporium sativum)) and leaf rust (Puccinia recondita). Winter wheat yield after different predecessors varied from 5.16 t/ha for pure fallow to 3.77–4.04 t/ha after nonfallow predecessors with a significant increase in adaptive-integrated plant protection by 0.37 t/ha (9.2%) and insignificant — for combined tillage in crop rotation — by 0.19 t/ha (4.6%).
