Subject. The article addresses the economic, scientific, technological, and production activities of processing plants within the agri-industrial complex. Objectives. The study aim to analyze and describe the specifics of storing perishable agricultural products, and the impact on both the further processing and final results of a processing enterprise. Methods. We employ methods of analysis and synthesis, grouping and comparison, abstraction, generalization, and analogy. We provide a mathematical model that describes the sugar beet processing, taking into account the level of sugar content, based on methods of mathematical modeling and optimization theory. Results. Our analysis of the influence of storage time of perishable agricultural products on their further processing showed that this factor can have a serious impact on the results of processing enterprises. We investigated the issue, using the case of such an important technical culture as sugar beet. We highlight an important factor, which can significantly improve the results of economic activity of enterprises, i.e. the formation of a schedule for the order of processing of sugar beet with different levels of sugar content. Conclusions. To maximize the final output, the sugar beet processing should start with batches of maximum sugar content. We provide assessments, characterizing the level of final output, should this rule be violated. The findings may serve as a basis for developing more general mathematical models, which describe the sugar beet processing and consider other factors, including the dynamics of the process of beet pile fields replenishment with sugar beet of various sugar content.

This paper analyzes the impact of genes and proportional contribution of parental genotypes on the inheritance of root yield and sugar content in diploid hybrids of sugar beet. The survey included two diploid male-sterile monogerm lines and three single (SC) male-sterile hybrids as maternal components, while three multigerm diploids were used as pollinators. The partitioning of genotypic variance into additive and dominant components was performed by half sibling (HS) and full sibling (FS) covariance. The proportional contribution of individual components of crossbreeding (lines, testers, and interactions) was exhibited in the expression of certain characteristics of F1generation. Genotypic variance components showed a significant effect of nonadditive gene action (dominance) in the inheritance of root yield and sugar content, while the additive effect of genes was less significant. Maternal components had a greater proportional contribution to root yield, while lines, pollinators, and their interactions had an equal contribution to sugar content.

Moderate Climate

In Poland, under conditions of the moderate climate and transition between maritime and continental climates, the average rainfall totals of the growing season are in the range of 350–400 mm; however, they are distinguished by great temporal and spatial variability. Climatological studies demonstrate that the drought frequency is approximately 30%. Therefore, under such conditions, irrigation has a supplementary and intervention nature and is applied only when dry periods occur. The aim of this study was to determine the impact of sprinkler irrigation and increased nitrogen fertilization on the yield and quality of sugar beet roots and yield of sugar. The average increase of the yield under irrigation was 18.1 t·ha−1 which constituted a 22.8% increase in the yield. Furthermore, there was a marked tendency of a higher sugar content in the roots of irrigated plants. The absolute, relative, and unit average sugar beet root yield increases obtained under the influence of sprinkler irrigation and the lack of a significant diversity in the sugar content in roots confirm that irrigation contributed to an appropriate pace of plant growth and development. The increased rate of nitrogen fertilization (N2) of 160 kg N·ha−1 plus an additional 40 kg N·ha−1 resulted in the significantly greater root yields compared to the control (N1) (160 kg N·ha−1), i.e., an average of 7.6 t·ha−1 (9%). Based on the crop-water production function, the maximum root yields were obtained for the N1 rate at a total precipitation and irrigation amount of 382 mm, compared with 367 mm for the N2 rate.

The Impact

Sugar beet is considered as biogas substrate because of its high yield. However, varieties differ in quality, in particular sugar content, which might affect biogas formation. The study aimed at analysing the impact of different beet qualities on biogas formation. Furthermore, parameters describing beet quality for anaerobic digestion should be found. From 2009 to 2011 field trials with several sugar beet varieties and a fodder beet variety were conducted with different N application rates at sites near Göttingen and Regensburg to get a broad range of beet qualities. The dry matter composition of beets, leaves, winter beet, bolters and maize was analysed. Discontinuous batch trials with fresh beet material were conducted to determine biogas formation. Sugar beet varieties did not differ in their dry matter composition and thus in biogas formation, whereas differences occurred between sugar beet and other substrates. Sugar beet was characterised by a high content of organic dry matter (98% oDM). The degradation time was mainly affected by the crude fibre content of the material. Therefore 90% of the biogas from sugar beet was formed within 3.5 days, whereas from winter beet, bolters and maize it took more than 10 days. The calculation of the specific biogas yield of different sugar beet qualities with two formulae resulted in lower values than determined in batch trials. A formula was derived to assess sugar beet quality for anaerobic digestion based on the sugar content, as increasing sugar contents lead to increasing specific biogas yields per kilogramme fresh matter.

Small-plot trials conducted in 2013–2015 studied the impact of longer vegetation periods (by means of earlier drilling and/or later harvest) on production results of two sugar beet cultivars – one nematode-tolerant cultivar and one cultivar without such tolerance. The trials took place at two sites with different Heterodera schachtii infestation levels. In all trial seasons, root yield was significantly higher in the earlier drilled plots. On average, prolongation of the vegetation period in spring by 13 days increased root yield by 10.9%. Therefore, each day by which drilling is postponed represents a 0.7–0.8% loss of yield. As to sugar content, no statistically significant benefit of vegetation period prolongation by early drilling was found. The spring gain was slightly higher for the non-tolerant cultivar than for the tolerant one on average over all trial seasons. This result confirms the theory that nematodes impact the crop mainly in later stages of vegetation, and early drilling can thus help eliminating, to a certain degree, the risk of nematode damage. In the autumn, root yield increased by 14.3% on average over 39 days. The autumn daily gain was about half of the rate found in the spring. The increase in sugar content was between 0.6% and 1% (abs.) on average. Autumn growth achieved at the non-infested site was much higher than at the infested site.

The Impact

Given the turbulence of the external and internal environment caused by the coronavirus pandemic, the agro-industrial complex is one of the few sectors that continued to show growth during the crisis of the global and Russian economies. Factors of the stability of the agro-indus-trial complex development were not only active state support, introduction of innovations, use of import substitution programs, but the fact that the sector did not stop working during the Covid19 pandemic. This has had an impact on the change in the Russian foreign trade system in terms of the geography of supplies, their volumes, and the commodity structure. The agricultural sector has become export-oriented and, in the sales structure, the traditional group of leaders, which include various types of raw materials for energetics, has given way to the sale of agricultural products. The article analyzes statistical information on foreign trade in agricultural products, concludes about the impact on the agricultural trade balance of the corona-virus pandemic, the ruble devaluation, changes in consumer demand and gap in international supply logistics due to restrictions on movement be-tween countries.

Crop Density

The economic growth and welfare of the state largely dependent on the efficiency of the agro-industrial complex, including the beet-sugar subcomplex. In Russia, including the middle CIS-Ural region, sugar beet is the main technical crop that provides raw materials for the sugar industry. More than 70 % of the area is sown in the Central and Southern Federal Districts. On the territory of the middle CIS-Ural region, sugar beet is currently cultivated on an area of more than 100,000 ha (Kornienko, 2014) The purpose of the research was to identify the productivity and technological quality patterns of new sugar beet hybrids, the influence of varietal characteristics on the content of molassigenic sub-stances, nitrogen fertilizer dosage, crop density and harvest time to obtain the highest yield of root crops with high technological qualities in the middle CIS-Ural region of Russia. Four field studies were conducted. The sugar content was determined by cold digestion with saccharimeter-polarimeter. To determine the α-amino nitrogen, the method of Stanek and Pavlas modified by Wininger and Kubadinov was used. The results showed that with an increased dose of nitrogen fertilizer, the sugar content of the root crops naturally decreased. As the crop density increased, the sugar content also increased. The highest sugar content in the root crops was revealed at a crop density of 95,000 and 110,000 plants/ha. The authors proposed recommendations to obtain the highest gross yield of purified sugar in sugar beet cultivation: for early harvesting – cultivate a sugar beet hybrid of normal-sugary type (Christella), for late harvesting – a hybrid of yielding type (HM-1820); apply nitrogen fertilizer at a dose of 160 kg of active agent/ha;cultivate sugar beet with a density of 95,000 plants per hectare; remove sugar beetroot crops with modern beet harvesters on October 10–25.

Abstract. The Russian agrarian sector of the economy ensures the food security of the state and, solving the tasks of minimizing the import of agricultural products, raw materials and foodstuffs, the vector of its strategic development focuses on the export of food products and other agricultural products. The purpose of this study is to identify the actual state of exports of agricultural products produced by domestic agricultural producers. Methods. The article uses such research methods as the method of analysis and synthesis, the method of forecasting and the method of comparative analysis. The results of the article are that the analysis of statistical and other official documents in the field of export of Russian agricultural products shows that the direction of the agrarian sector of the economy in the field of food self-sufficiency is receiving sustainable development, despite the existing problems in the field of geopolitics and geoeconomics, which have a transformational impact on Russian agriculture. economy and agro-industrial complex. If we cite statistical data, then more than 1030 suppliers of Russian-made products appeared only in 2019, and the share of domestic goods is now 89 %. Moreover, 35 % are Sverdlovsk producers. This is a prerequisite for supporting domestic producers. And domestically produced goods have now received high recognition from the townspeople, as they are the most environmentally friendly and high-quality, and most importantly, fresh, because fresh products can be bought in a shop near the house. The scientific novelty of the research is characterized by a new approach to the formation and development of the international agri-food market with the active participation of Russian agriculture and the agro-industrial complex.

The Impact

In this paper it is noted that the important problem of the existing economic relations in the agrarian sphere is the choice of forms of management. The practice of reforms in agriculture has shown that more than 80% of gross output in Kazakhstan is currently produced by "households" and peasant (farmer) farms which provides further increase in the production of agricultural products namely crop production and increase its economic efficiency. Currently the agricultural sector has a tendency to small-scale production. As the situation has shown one of the main factors negatively influencing investment activity is financial instability of the majority of agricultural producers, low level of its profitability and significant risks.  Factors of low profit growth of the agricultural sector are related to the peculiarities of demand for agricultural products and seasonality of production in this industry. The analysis of the structure of gross agricultural production of the Republic of Kazakhstan by categories of farms, the returnability of agricultural production for 2012-2016 shows the impact of the price and yield of grain on the level of farm income. Proposals for further improvement of grain pricing are given.

Key Questions

The article discusses the impact of the growing urbanized world on the agro-industrial complex and agriculture, as well as a decrease in the attitude of agricultural producers to consumers. On a global scale, agriculture meets the needs of a rapidly growing urban population, including products that are becoming more energy-intensive, resource-intensive. Thus, the key questions regarding agriculture and urbanization are whether it is possible to meet the growing and changing demand for agricultural products from the growing urban population, while supporting the prosperity of agriculture and modernizing the principles of urban development. The article concludes that there are increasing trends in urbanization of rural regions in the conditions of new global economic realities, as well as the simultaneous process of deurbanization of countries with low economic potential.
