Phytosanitary condition and yield of winter wheat in crop rotations of the forest-steppe zone of the Volga region

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%).

GRAIN YIELD OF SOYBEAN VARIETIES OF DIFFERENT MATURITY GROUPS IN THE FOREST-STEPPE ZONE OF THE MIDDLE VOLGA REGION

The experiments were carried out in non-watering conditions of the forest-steppe of the middle Volga region in the fields of Samara Research Institute in 2016-2018. The purpose of the research is to study the features of grain yield formation in soybean varieties of different maturity groups in order to create new varieties of Volga ecotype with high and stable grain yield. The material for the study was 29 soybean varieties of different agroecotypes and maturity groups. Standard is Samer 3. Observations and records were carried out according to the generally accepted methodology. Meteorological conditions in 2016-2018 characterized as arid, the hydrothermal coefficient varied from 0.5 to 0.7. On average, over the years of testing, the studied varieties were classified as very early – with a vegetation period of 86…90 days (8 varieties) and early 91…109 days (21 varieties), including the Samer 3 standard, ripeness groups. The high grain yield over the years of testing was in the early ripeness group - 1.95 t/ha. The sum of active temperatures above 10°C (r=+0.993…+0.999) and the amount of precipitation (r=+0.845…+0.939) had a significant impact on the duration of vegetation of both groups of ripeness in all years. A significant influence of the hydrothermal coefficient and the average daily temperature on the duration of vegetation was, revealed in 2017 and 2018. The correlation of vegetation duration with the hydrothermal coefficient was r=-0.767…-0.977, and with an average daily temperature of r=-0.902…-0.970. Among the varieties of different groups of ripeness, high seed yields (2.00…2.21 t/ha) on average over the years of testing had: Oressa, Swapa, Samer 1, Lira, Cordoba, Lisbon, Malaga

‘The province…But, indeed, that is Russia!’

“The Imagined Province” investigates the shifts in what the “idea of the province” in the period of world war and the Russian revolution and civil war. I argue that the mental and emotional valence of Russia’s map changed markedly over these nine years as regionalist and provincial pride came into literary culture, urging a fresh view of central Russia outside the capital cities. This change of perspective emerges in essays, stories, and poetry throughout Central Russia, though this article focuses mainly on the Volga Region. Authors of many different political stripes contributed to this shift—among them, regionalists like Evgenii Chirikov and Nikolai Kliuev, pro-revolutionary socialists such as Maksim Gor’kii and Matvei Dudorov, and Bolsheviks like Aleksei Dorogoichenko and Fedor Bogorodskii. As the Bolsheviks regathered Russia, these provincial voices were overpowered by more prominent voices from the center. Nonetheless, they established a “usable history” that remains a substrate of Russian culture even today, challenging the simplistic binary juxtaposing “capital” and “province.”

Coin Finds in 14th-Century Burials in Saryarka (Central Kazakhstan)

Excavations of two significant archaeological sites were carried out in 2020 in Akmola and North Kazakhstan regions of Kazakhstan. The mausoleum of Janibek and the mausoleum on Kyzyloba site were examined. Brief descriptions and characteristics of these archaeological sites are given. Only the found Juchid coins are considered in detail in this paper. The analysis of numismatic material showed: 1. the burial in Janibek’s mausoleum contains 13 coins of the 14th century and dates from the first half of the 760s/1360s; 2. the burial in Kyzyloba’s mausoleum contains 4 coins of Khan Uzbek and dates from the second half of the 730s/1330s. The authors compare the coins with similar finds from other graves of the 14th century in Central Kazakhstan. The obtained data indicate a possibly different dynamics and scale of the spread of plague in Saryarka compared to the Volga region. A larger statistics of coin finds in 14th-century burials is required for relevant conclusions.

Typological originality of secondary dialects with the south Russian basis in the Middle Volga Region

The article highlights the problem of the typology of dialects of the Middle Volga region. Particular attention is paid to secondary dialects with signs of South Russian dialect bases, the status of which in the Volga atlases is determined ambiguously. The area of the described dialect type is indicated. It is indicated that in the left-bank part of the Middle Volga region, in the so-called Trans-Volga region, there is a high probability of the existence of secondary Central Russian dialects with the preservation of signs of southern Russian maternal stems. The main source is data from regional atlases. The materials of dialectological expeditions to the villages of the Samara region are used. The description of the typological characteristics of the secondary dialects with a southern base, which are designated on the maps of regional atlases as Central Russian, is based on the analysis of isogloss of phonetic, grammatical and proper lexical dialect phenomena. In dialects with a completed transition to Central Russian, typologically significant South Russian features are types of yakany with the preservation of vowel dissimilation, obstruent pronunciation of g of secondary origin and other phonetic, morphological and lexical features that make up the series of two-term dialectal correspondences. According to the linguistic basis, such dialects are often polydialectal. In some dialects, the South Russian basis is not in doubt, and we can only state the beginning of the transition to the Central Russian type. The question is raised about the existence of secondary dialect types, formed as a result of the assimilation of dialects of the South Russian dialect with other dialects, not only in the Volga region, but also in other territories with favorable conditions for inter-dialectal contact. It is concluded that the presence of the Central Russian type and South Russian bases in the described dialects is possible only if there is a sufficient amount of information on typologically significant levels of the dialect language, in which systemic relations are clearly manifested and which are represented on linguistic maps by stable isoglosses. Data on secondary types of dialects should be based on the structural-typological classification of dialectal phenomena of various levels, including the lexical one.

Biological and economic evaluation of AMISTAR Gold fungicide against sunflower rust in the Lower Volga region

Rust is one of the most economically important foliar diseases of sunflower. The problem of sunflower disease control was considered. The article presents the results of a two-year experiment studying the efficiency of AMISTAR Gold fungicide, concentrated suspension (active ingredient: Azoxystrobin 125 g/L, Difenoconazole 125 g/L) in sunflower hybrids in the Lower Volga region. Flowerbud development stage was the best application timing for increasing productivity. Therefore, sunflower yield averaged 34 c/ha. The biological efficiency of the fungicide ranged from 85 to 90 %. The calculation of economic efficiency showed 145255 % profitability depending on the year.

Expenditures of Rural Societies and Volost Boards in the 1880s – 1890s (Based on the Materials of the Middle Volga Region)

Introduction. The comparative analysis of the expenditure part of rural and township budgets of the Middle Volga provinces in the 1880s – 1890s is presented. Materials and Methods. The study is based on the comparative method. Quantitative, problem-chronological, system analysis and structural methods were of auxiliary importance. Results. The comparison of data on the Middle Volga provinces shows that in the 1880s – early 1890s, the mundane expenses of rural societies were twice as high as the costs of the volost boards. A significant part of the worldly fees went to pay employees of volost boards; much more modest funds were allocated to representatives of peasant self-government bodies, and, in their totality, these funds were steadily declining at the end of the XIX century. Discussion. In many areas of the Middle Volga region in the 1890s, rural electors did not receive any payment at all. The item of expenditure of local self-government bodies designated as “other expenses for the management and conduct of all kinds of public affairs”, which included the costs of renting apartments for officials, paying for the travel of officials and elected officials, delivering taxes to the treasury, the costs of conducting court cases, hiring servants and accounting officials was quite noticeable for rural societies at the very beginning of the 1890s, but gradually decreased. The amounts spent under this article by rural societies significantly exceeded the volost ones. During the period under review, the protection of public safety and fire-fighting measures were financed mainly from the fees of rural societies. An important component of the “mundane budgets” were the so-called “agricultural expenditures”, which included a wide range of operations aimed at organizing agriculture and animal husbandry. Conclusion. The reform of taxation and the system of local self-government in Russia in the 60–70s of the XIX century provided rural societies with wider opportunities for spending funds to meet urgent needs. A certain independence in the approval of expenditure items can be traced in the specifics of the costs of individual volosts and rural societies of the Middle Volga provinces. Allocating a significant part of worldly fees for payments to employees of volost boards, the peasantry preferred to minimize their own expenses on self-government bodies. The costs of “managing and conducting all kinds of public affairs” were quite palpable for the villagers at the very beginning of the 1890s, but also gradually decreased.
