Abstract. The purpose of the current scientific paper is to reveal the effectiveness of foliar treatment with various types of complex fertilizers with microelements in chelated form on the dynamics of nitrogen, phosphorus and potassium in the leaves and roots of sugar beet plants. The novelty lies in the fact that for the first time in the forest-steppe conditions of the Middle Volga region, the authors carried out the research towards the effect of liquid microelement fertilizers on the content of macronutrients in sugar beet plants. Methods. The records and observations were organized according to the generally accepted methods. Results. It was found that 10 days after the first foliar treatment, the nitrogen content in the leaves increased by 0.36–1.08 %. However, a decrease in the accumulation of phosphorus and potassium was noted. In root crops during this period, the nitrogen content decreased by 0.32–0.45 %. There is a tendency towards a decrease in the concentration of phosphorus and potassium in comparison with its content before foliar treatment. Determination of the content of macronutrients 10 days after the second treatment showed that after foliar treatment of plants with “POLIDON Amino Tsink” and “POLIDON Bor”, the nitrogen content in the leaves increased by 0.82–0.88 %. In the same variants, a tendency for an increase in the phosphorus content was noted, but for all variants of the experiment, a decrease in the intake of potassium in the leaves of sugar beets was obvious. It was revealed that the nitrogen content in the leaves increased by 0.07 % after the introduction of boric and zinc-containing micronutrients 20 days before harvesting. With the use of microelement fertilizers, a tendency to an increase in the phosphorus content in the leaves was significant. In root crops, in all variants with microelements, an increase in nitrogen was observed. In the phosphorus content, no significant differences were found regardless of preparation type; a decrease in potassium was noted. The highest yield of root plants was obtained with three-fold foliar treatment of crops with “POLIDON Bor” and exceeded the control by 11.1 %.

In the article, a mathematical expression is obtained that characterizes the effect of the doses of introduced fertilizers, the content of nutrients in the soil and their absorption by sugar beet plants on the yield of this crop. With the help of the developed mathematical model, the optimal values of the content of macronutrients in soil and plants are determined: nitrogen ~ 21.81 mg/kg and 1.02 %; phosphorus ~ 58.88 mg/kg and 0.33 %; potassium ~ 120.21 mg/kg and 1.33%, respectively, which accumulate when introducing a complete fertilizer at a dose of N80P80K80. This leads to the achievement of the maximum yield of root crops, which corresponds to the calculated value of this indicator ≈of 56.94 and 64.6 t/ha and coincides with the experimental one = 57.9 and 62.0 t/ha, respectively, obtained in this variant. The introduced fertilizers containing boron contributed to a more intensive absorption of nitrogen, phosphorus and potassium by root crops. The use of trace elements causes a tendency to increase the yield of this crop.

The complex effect of pre-sowing treatment of seeds with a protectant and liquid mineral fertilizer with subsequent foliar feeding on the growth processes and the formation of elements of productivity of hemp in the conditions of the forest-steppe of the Middle Volga region was studied. Studies have established that treatment of seeds before sowing by fungicide TMTD, VSC at the dose rate of 2.5-5.0 l/t provided the safety of the plant to harvest to 88,0-89,8 %, fertilizer Isagri Force at a rate of 1.0 l/t -- of 90.2 %. The positive influence of the investigated factors on yield structure elements: the length of inflorescence increased with the use of drugs TMTD, VSC and Isagri Force to study the consumption rates of 22.9 and 37.1 %, adding foliar treatment by 20,0% compared with the control without treatments. A significant increase in the diameter of the stem was observed when processing seeds with TMTD, VSK and Izagri Force in the consumption rates of 2.5 and 1.0 l / t by 9.5 % compared to the control. The increase in the number of internodes was promoted by treatment with drugs TMTD, VSC at a rate of 5.0 l/t and Isagri Force in doses of 1.0 and 0.5 l/t in comparison with control without treatments. Pre-sowing treatment with Izagri Force fertilizer in the consumption rates of 0.5-1.0 l / t increased the yield of seeds by 4.3 – 7.5 %. A statistically significant increase in this indicator relative to the control variant was found in the variants with Izagri Phosphorus treatment for vegetation (+0.17 t/ha or 13.6 %). The most responsive hemp plants were on the interaction of the mordant, fertilizer and foliar feeding of plants during vegetation, the increase in yield was 0.38 t / ha.

Term Storage

The paper deals with the results of research on the study of the technological traits changes in foreign hybrids root crops of the KWS company sugar beet enterprises under the influence of long-term storage and their economic efficiency. The conducted researches are especially relevant due to insufficiently studied issues of changes in the technological traits of the root crops of the newest hybrids during their storage in the crutches on the field or at the sugar factory. Estimation of new hybrids of sugar beet by regions of the Forest-steppe allows to predict the genetically determined degree of their plasticity and stability both in the yield and the quality. Hybrids with higher resistance to extreme temperatures are especially valuable. The researches were carried out during 2014–2015 at the "Rasavske" Ltd. of Kaharlyk district, Kyiv region. The sugar content in the root crops increased from 1.6% in the Alyona hybrid to 5.9 % in the Daria hybrid and 6.1 % in the Coryda hybrid, due to the loss of moisture during their prolonged storage. The content of soluble dry matter in the root crops increased from 1.7 % in the Alyona hybrid to 7.7 % in the Coryda hybrid for the same reason. The conducted calculations of cell juice quality showed that long-term storage resulted in the highest growth of this indicator by 8.2 % in the Cesaria hybrid and by 7.5 % in the Acatsia hybrid. In the Alyona hybrid, the growth rate of cell juice quality was only 0.8 %, while the Corida hybrid had the quality of the previous level. In the Olesya hybrid, this indicator decreased by 1.8 % compared with the previous determination period (October 10). The costs of growing root crops ranged from 17,859 to 20,726 UAH/ha. The highest profit was 17435 UAH/ha and the profitability level was 86.3 % for the Alyona hybrid, while the lowest economic efficiency figures were for the profit of 10,201 UAH/ha and the profitability level of 53.7 % in the Carmelite hybrid. The highest rates of the technological traits of root crops during the long-term storage of sugar beet were determined in the Alyona hybrid. The highest yield of root crops was in the Daria hybrid – 79.8 t/ha. According to the indicators of economic efficiency the Alona hybrid was the best in terms of profit (17,435 UAH/ha) and the profitability level of 86.3 %. Key words: sugar beet, hybrids, productivity, yield, sugar content, technological traits, profit, profitability level.

The results of field and laboratory research on podzolized heavy loam chernozem of the Right-Bank Forest-Steppe of Ukraine to study the effect of various fertilization systems on the infestation of sugar beet by cercosporosis and gray rot are presented. It has been found that changes in nitrogen, phosphorus and potassium nutrition have a different effect on the development of diseases. The semi-rotted cattle manure on straw bedding and mineral fertilizers in the form of aqueous ammonia, ammonium nitrate, granular superphosphate, mixed potassium salt, potassium chloride, ammonium nitrate phosphate fertilizer grade A and liquid complex fertilizers of grade 10–34–0 were used in the experiment. The rate of manure is 40 t/ha, the rate of mineral fertilizers – N120Р120К120. Fertilizers were applied in August during fall plowing, as well as in late autumn at the end of October, together with the soil subsurface loosening to a depth of 14–16 cm, and in spring – for presowing cultivation. The degree of the leaf apparatus damage by cercosporosis and the intensity of the disease development were determined. The resistance of root crops to gray rot was determined by a microbiological method. For this, cuttings from root crops were placed in Petri dishes with a provocative background of a pure culture of the fungus Botritis cinerea Pers. The conducted studies have established that, depending on the types, forms and timing of mineral fertilizers against the background of manure, the degree of the leaf apparatus infestation of beets with sugar cercosporosis varies from 24 to 48 % and increases both for insufficient and unbalanced phosphorus nutrition. At the same time, the improvement of nitrogen nutrition, especially with the late autumn application of aqueous ammonia, compared with its introduction for the August plowing, contributes to an increase in the degree of stability of the leaf apparatus of sugar beet to cercosporosis from 46.6 to 60.0 %. Improving the mineral nutrition of plants through the use of fertilizers helps to increase the resistance of root crops to decay. At the same time, depending on the fertilizer application system, the degree of stability compared to the control without fertilizers increases by 8.5–38.9 %. This was especially effectively promoted by the improvement of phosphorus nutrition of plants. A high correlation dependence was established between the damage of leaf apparatus of sugar beet by cercosporosis and the formation of a rotten mass of root crops (r = 0.85).

Modern sugar beet hybrids have a potential root crop capacity of above 50.0 t/ha and sugar content of 16.1–18.5 %. Seeds with a germination rate of not less than 90 % are being used in this case, highly efficient energy-saving technologies based on the use of agricultural techniques (crop rotation, fertilization system, soil tillage system, sowing at the final density), protection against pests and diseases, the method of harvesting root crops are used. The performance of the sugar beet hybrid is mainly determined by the genetic information contained in the seeds and the conditions in which the plants grow. The purpose of the research was to investigate the varietal features of growth, development and productivity of sugar beet in the conditions of the central part of the Right-bank forest-steppe of Ukraine. The following sugar beet hybrids were used for sowing: Olzhych, Etude, Zluka, Constanta and Anichka with the fraction of 3.5–4.5 mm and laboratory germination of 85–90 %. The growth and development of sugar beet plants of different hybrids differed. There was a tendency for more positive germination of seeds and a more complete density of seedlings in the hybrid Constanta. The productivity of the sugar beet root crops is determined by the yield, sugar content and sugar harvest. Crop capacity of the male sterile hybrids studied averaged from 46.4 to 55.6 t/ha over the three years of studies, sugar content – 15.6–17.0 % and sugar yield – 7.4–9.5 t/ha. Hybrids Zluka and Constanta appeared to be the most adapted to the conditions of the central part of the right-bank forest-steppe of Ukraine. Thus, over three years, the Zluka hybrid had an average crop capacity of 55.6 t/ha, the sugar content of the roots was 16.1 %, the sugar harvest was 9.0 t/ha, and the hybrid Constant had a yield of 55.1 t/ha, the sugar content of the roots – 16.2 %, sugar yield – 8.1 t/ha. Key words: sugar beets, hybrids, field germination of seeds, sugar content, sugar yield.

Fertilization Level

Soil tillage and fertilization level are important in the system of agro-technical measures that increase soil fertility and sugar beets productivity. Today the cultivation of this crop requires a great deal of expense, therefore, there is a need for a wider study of the use of cheap soil cultivation, soil protection, energy-saving soil tillage technologies and appropriate ferti-lization levels. Under western Forest-Steppe of Ukraine conditions, investigations were conducted on dark grey podzolic light loamy soils where the influence of tillage models and fertilization levels on the formation of sugar beets root crops was studied. Shallow no-plow tillage of the soil on 14-16 cm is expedient to use as a main tillage under sugar beets. Under favorable weather and climatic conditions, it can provide yielding capacity at the level of deep fall plowing. The use of shallow no-plow tillage helped to increase the yielding capacity of sugar beet roots relative to plowing by 28-30 cm for 1.3 t / ha and the biological sugar output – for 0.2 t / ha. Then the sugar content was by 0.1% higher in the application of deep fall plowing on 28-30 cm. The optimization of the system of sugar beets fertilization allows ensuring the growth of the yielding capacity of root crops. It is established that the application of fertilizer norm N300P225K350 provides the yielding capacity at the level of 90 t / ha. The sugar content of root crops at the given fertilizer rate was the lowest in the experiment - 16.5 – 16.6%. Thanks to the high yielding capacity of root crops in terms of N300P225K350, the sugar harvesting was the highest and depending on the method of basic soil tillage was 14.95 – 14.79 t / ha. That is in 3.2 times more as to the control, in 1.3 times more than the norm of N180P135K210 and in 1.1 more than the fertilization level N240P180K280.

In January 2021 the UK government granted an application for authorisation to use thiamethoxam, a neonicotinoid pesticide, to protect commercial sugar beet crops from attack by viruses transmitted by aphids. This was the first time such an authorisation had been granted in the United Kingdom (UK) and there were concerns that it signalled a weakening of environmental standards now that the UK was no longer part of the European Union. In fact, similar authorisations had been granted by several European Member States in the last 2 years, despite the ban on the use of neonicotinoids introduced in 2018. Nevertheless, the reasons for granting the authorisation do suggest that the balance between adopting a precautionary approach to environmental protection and taking emergency action to protect economic interests may have shifted. It was acknowledged that the proposed mitigation to safeguard bees and other wildlife was not entirely satisfactory. In the end, due to unforeseen weather conditions it meant that the pesticide is not necessary, which in itself demonstrates that short-term emergency measures are unsuitable for dealing with the problem. If the sugar beet industry is to continue to prosper in the UK, it will need to be managed in a way that provides resistance to virus infection without the use of controversial chemicals.

Abstract In 2017, an expedition of the Institute of Archeology of the University of Rzeszów (Poland) carried out excavations on a hillfort belonging to the Scythian cultural circle (its forest-steppe variant) in Chotyniec, in south-eastern Poland. The hillfort is the central and most important point of a large settlement cluster, which is the furthest north-western enclave of this cultural circle. In an excavated cult object – the so-called ‘zolnik’ – we made an interesting discovery. Here we show this unique finding for the first time: a Greek wine amphora, from the beginning of the sixth century BC. We were able to explore and reconstruct it almost entirely. Amphora is the only artefact of this type found in the present Polish borders. The amphora was subjected to archaeometric research with the use of PLM, SEM/EDS, TXRF and ToF SIMS. The massive fabric was made of high calcium clay enriched in quartz and volcanic lithoclasts. The lack of chromium and nickel among trace elements makes the vessel different from the amphoras from the Eastern Meditteranean analysed so far, suggesting a specific workshop. Red painting was executed with very fine grained iron compounds predominantly based on aluminosilicates, enriched in phosphorus. Obviously, since it is associated with the presence of Scythians in Eastern Europe, it simultaneously delimits (geography-wise) the borders of Greek influence.

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.
