Authors: BAŞKAYA Sadiye Kübra , ÇEŞME Mustafa
Published: December 2021

Carbon quantum dots (CQDs); It is a carbon-based nanomaterial that has become popular in recent years due to its advantages such as biocompatibility, tunable fluorescent properties, simple and economical synthesis methods. In this study, synthesis of N-doped carbon quantum dots by hydrothermal synthesis method using tangerine juice, onion shell and ethylenediamine was investigated. The structures and optical properties of the synthesized carbon quantum dots were illuminated by photoluminescence (PL), X-ray Diffractometer (XRD), Infrared (IR) and UV-vis spectrometer. Electrochemical properties were examined by the cyclic voltammetry (CV) technique. The stability of N-doped carbon quantum dots (at 1st, 10th, 15th and 26th days) and pH-dependent emission properties were investigated. Peaks are seen at 285 nm and 347 nm in the UV-vis spectrum proved the presence of C=O and C=N bonds. It has been observed that there is a redshift in the absorption peak due to the amine groups in the structure of the N-doped carbon quantum dots. As a result of the XRD analysis, it was seen that the N-doped carbon quantum dots were in an amorphous structure. The FTIR spectrum of N-doped carbon quantum dots characteristic absorption bands of shows N-H vibration stretching and C-H bending peaks at 3240 and 2923 cm-1, respectively. These functional groups seen in the structure showed that N-CQD is bonded by hydrogen bond. In 1574 cm-1 and 1336 cm-1 C=O vibration stretching peaks and C-N vibration stretching peaks are observed. In the next step, the electrochemical properties of the carbon dots were examined by cyclic voltammetry technique. Different scanning rates (10-1000 mV/s) were used to understand and clarify the substance (mass) transport to the electrode surface.

Akciğer kanseri, dünyada kansere bağlı en yüksek ölüme neden olan kötü huylu ve saldırgan tümörlerden biridir. İfosfamid, akciğer kanserinin de dâhil olduğu birçok kanser tedavisinde kullanılan alkilleyici bir antineoplastik ajandır. Curcuma longa rizomundan elde edilen bir flavonoid olan kurkumin'in, insan kanserlerinde hücre büyümesinin inhibisyonu, hücre döngüsü dudurulması ve pro-apoptotik etki yoluyla kemoterapötik aktiviteye sahip olduğu gösterilmiştir. Bununla birlikte, İfosfamid ve Kurkumin kombinasyonunun küçük hücreli olmayan akciğer kanseri (NSCLC) üzerindeki etkileri henüz doğrudan ele alınmamıştır. Bu çalışmada akciğer kanseri hücre hattı A549'da, İfosfamid ve Kurkumin kombinasyonunun, hücre proliferasyonu, hücre içi ROS birikimi, apoptozis ve hücre göçü üzerine olan etkileri gerçek-zamanlı hücre analizi, DCFDA floresan işaretleme, western blot ve yara iyileşme-hücre göçü testleri ile araştırılmıştır. A549 hücrelerinde, İfosfamid-kurkumin kombinasyonu ile tedavi sonrasında, hücre içi ROS birikiminde ve pro-apoptotik Bax proteinin düzeyinde bir artış olduğu belirlendi. Ayrıca, kombinasyonun, tedavi edilmeyen ve tek ajan ile tedavi edilen hücrelere kıyasla, anti-apoptotik TIGAR protein düzeyinin azalmasında ve çizilen alana hücre göçünün bastırılmasında etkili olduğu belirlendi. Bulgularımız, Kurkuminin, küçük hücreli olmayan akciğer kanseri hücre hattın A549’da İfosfamidin etkinliğini artırdığını göstermektedir.

Melatonin Enhances the Chemosensitivity of Pancreatic Carcinoma Cells (PANC-1) to Cisplatin and Cetuximab through modulation of p21, p27, p53, p57, MDM2 and KRAS Genes
Authors: GÜR Cihan , ÖZKANLAR Seçkin
Published: December 2021

We investigated the effects of melatonin, cetuximab and cisplatin treatments alone or in combination on PANC-1 cells from a human pancreatic carcinoma of ductal cell origin through cell viability and gene expressions. The cells were left for 48 h incubation after applying chemicals on the PANC-1 cells. The metabolic effects of the substances on cell viability at the end of incubation were measured by MTT assay. The gene expressions of p21, p27, p53, p57, MDM2 and KRAS were determined by RT-PCR. The use of melatonin combined with cisplatin or cetuximab increased p21 and p57 genes and decreased KRAS gene. Furthermore, melatonin combined with cetuximab increased p27 gene expression and decreased the cell viability compared to cetuximab alone. The cell viability was the lowest in cisplatin and cisplatin plus melatonin and/or cetuximab groups. The p53 were highest in the cisplatin groups while cisplatin plus melatonin decreased the p53 gene and its autoregulator MDM2 gene compared to cisplatin alone. In conclusion, melatonin in combinations with cisplatin and cetuximab enhances the tumor suppressor genes p21, p27 and p57 along with a modulation of the oncogenic gene KRAS suggesting the potential of melatonin as a therapeutic approach in combination therapy of pancreatic ductal adenocarcinoma.

A Pós-modernidade sob análise: reflexão e crítica dos teólogos da libertação
Authors: Lavôr e Silva Isabel de
Published: December 2021

A pós-modernidade ficou conhecida como um período fortemente marcado pelo individualismo, pelo uso excessivo da tecnologia, e perda de valores tidos como certos pela modernidade. Tais mudanças alteraram a cultura, a arte, a política e a relação entre os indivíduos, estabelecendo novos vínculos entre a religião e a espiritualidade. Diante deste cenário, o presente artigo tem por objetivo, refletir acerca desse período histórico, tendo como referência teórica, a Teologia da Libertação. A partir das contribuições dos teólogos da libertação, busca-se compreender de que maneira esses líderes interpretam a religiosidade pós-moderna. Os representantes da Teologia da Libertação defendem uma corrente teológica que sempre buscou a emancipação dos pobres e a justiça social, conclamando a Igreja a uma maior participação política. Deste modo, o olhar destes pensadores irá nortear a pesquisa, haja visto seu engajamento com temáticas recorrentes da pós-modernidade, em busca de uma relação dialógica com a espiritualidade e teologia.
Pós-modernidade e a busca de sentido da vida: o neopentecostalismo da IURD e a racionalização da magia como identidade
Authors: Barsalini Glauco , Mororó Natália Fernandes
Published: December 2021

Este artigo investiga a crise de identidade na pós-modernidade e, também, como os novos movimentos religiosos pentecostais ganharam espaço neste contexto. A proposta acontece em torno de uma instituição neopentecostal que se aproxima dos sujeitos em crise através das mídias sociais, inclusive por meio de programas televisivos presentes no cotidiano dos brasileiros. Perscruta, através de pesquisas já realizadas com membros desta instituição e do site oficial da Igreja Universal do Reino de Deus (IURD), os significados que a sua teologia (denominada por Teologia da Prosperidade) ganham no dia a dia dos fiéis, que esta instituição religiosa chamará de organização de vida e superação das dificuldades do cotidiano. Ao referenciar-se em pensadores contemporâneos como Zygmunt Bauman, Stuart Hall e Anthony Giddens, na teologia crítica, na sociologia da religião, na antropologia da religião e nas ciências da religião, o método utilizado combina o estudo bibliográfico com a netnografia.

Healt h capital as the basis for the functioning of human capital in the context of the COVID–19 pandemic
Authors: Yessimzhanova S. R.
Published: December 2021

The article examines health capital as the basis for the functioning of human capital. The issue of understanding of human capital importance is still relevant for Kazakhstan, as well as in the development and implementation of its development model. Based on the analysis of demographic indicators characterizing the health of the population of Kazakhstan, revealed the negative trends in indicators of life expectancy and mortality caused by COVID–19. Marketing research conducted by interviewing patients showed for the most part their dissatisfaction with the quality of medical services provided, and the results of the expert survey made it possible to identify problems in medical care in the conditions of COVID–19 and identify ways to solve them. The analysis of the indicators allowed us to conclude that the health of the population in Kazakhstan has deteriorated over the past two years. Today, there is an acute shortage of personnel in healthcare institutions, especially in rural areas. Insufficient number of medical personnel leads to exceeding the specific weight of the time required for patient care, which affects the timeliness and quality of medical services. Not everyone receives a guaranteed amount of free medical care under the CSHI, the unemployed and the self-employed left behind. As a result, there is an objective need to increase investments in healthcare both from the state and from companies, as well as an individual.

Published: December 2021

The purpose of the article is to examine the state of the tax system in an unstable economy. The initial condition is the lack of uniform methodological and methodological approaches to the formation and organization of the tax system. This study is based on the theoretical provisions of the institutional theory, systemic and synergistic approaches. The main research methods used were analysis and synthesis, methods of induction and deduction, the method of designing hypotheses. The article examines the dynamics and structure of tax payments in the traditional approach to tax regulation. The question of determining the role of direct and indirect taxes is undoubtedly important for a comprehensive analysis of the taxation system since the influence of each of them on the economy is differentiated. The directions of modernization of the system of taxation regulation, the impact of mechanisms, methods, and instruments of tax regulation on various segments of the national economy, primarily on industries that ensure economic growth, have been investigated. The lack of a clear structuring of the elements of tax revenues becomes a serious obstacle to obtaining an adequate assessment of the impact of tax policy on various aspects of the country's socio-economic development. The state tax policy should be aimed at balancing the budget, improving the quality of its implementation, adhering to the timing of the budgetary process and, as a result, ensuring socioeconomic growth. The theoretical and practical significance of the study is to substantiate the need to adapt the tax system to ensure sustainable growth of the national economy.

Den (din ) – spiritual divergence of the prayers of the ancient akyns and the teachings of Zarathushtra
Authors: Alshanov R. A.
Published: December 2021

The purpose of the study is to consider the problem of the spiritual divergence of the prayers of the ancient Akyns and the teachings of Zarathustra. The words «den koyu» – «pay attention to someone, something»; «den koyyp tyndau» – «listen carefully, make sure of something» can mean as a call to listeners to carefully delve into the text of prayers, listen and make sure of the arguments and messages of the prayer appeal. There was a long-term struggle for their understanding, perhaps there were also supporters of the new teaching, new prayers. The reflection of customs, everyday life, rituals, as well as natural events, including cataclysms in legends, prayers in one form or another were a kind of translation of the accumulated experience, the transmission of what they saw to the next generations. Zarathustra initially presents himself as a preacher of the prayers of Akhuna Bairi and, his ascetic, brings to the people the chants of Bayyr akyn, who eventually transformed from Bayyri Akhun into the most ancient, Bayyrgy Akyn. During the evolutionary reinterpretation of prayers, Zarathustra went through a stage of transformation, rebirth from a violent preacher into a fierce reformer who opposed the traditionalists – supporters of the prayers of the ancient Akyns. Zarathustra's departure from the established foundations was considered by his countrymen as a betrayal of ancient prayers. The article examines the question: what did he say to his people, that they did not understand him.

Published: December 2021

Pregledom postojeće literature moguće je zaključiti kako se karakteristike i sklonosti pojedinih generacija bitno razlikuju, što dovodi do nesporazuma u poslovnoj komunikaciji. U ovom radu ispitano je 144 zaposlenika, pripadnika generacije X i Y radi utvrđivanja preferiranih oblika komunikacije i učestalosti međusobnih nesporazuma. Također ispitana su međusobna viđenja po različitim elementima radnog ponašanja, deriviranih iz prijašnjih istraživanja. Rezultati pokazuju visoko međusobno slaganje pripadnika generacije X u percepciji generacije Y, većinom u smjeru koji sugeriraju prijašnja istraživanja. S većinom se takvih percepcija slaže i najveći dio ispitane generacije Y, no s vidljivo manjim stupnjem međusobnog slaganja. Pronađene su i razlike u preferiranim oblicima komunikacije, pri čemu generacija X preferira više usmenu komunikaciju, s čime je moguće povezati i nalaz kako ta generacija rjeđe doživljava komunikacijske nesporazume, nego generacija Y.

Peas, as a valuable nutritious and cultivated plant (Myers et al., 2010), have recently received special attention for the improvement of new varieties (Kreplak et al., 2019). They are increasingly adapted to any kind of environmental conditions. Thus, we want an increased production of grains, contents in active principles as high as possible (Pownall et al., 2010), but also to increase its proportion in the structure of crops on a farm. The Alvesta variety, studied for its specific morphological characters, is one of the newest creations. Even in the slightly drier conditions of the last period (two years), this variety formed plants with heights of 42-45 cm, with a total plant weight of 7.5 g. 10 knots were formed on a pea stem (at one node the floral and fruit raceme are caught and formed). Each plant formed 4 pods, weighing 6 g and 16 berries weighing 4.5-6 g. The bean had a diameter of 7 mm and the absolute weight of the berries was 215 g. Among these morphological characters were obtained significantly positive correlations in most cases. Insignificant situations were between the absolute mass of the berries with the size of the plant, with the number of nodes, with the total number of pods and with the number of berries on a plant. Only one insignificant negative correlation was observed between the number of nodes on the stem and the diameter of the grains. Regarding the variability of the determined characters, slightly higher values were found, mainly due to the existence of the dry bottom. And yet the Alvesta variety, with improved morphological characters proved to be a good adaptability to zonal cultivation conditions.

Published: December 2021

The personal recovery movement is beginning to gain traction within Singapore’s mental healthcare systems. We believe it is timely to give a broad overview of how it developed and provide suggestions on how it can evolve further. From the early custodial care in the 1800s to the community-centric programmes of the 1900s and early 2000s, we now find ourselves at the forefront of yet another paradigm shift towards a more consumer-centric model of care. The following decades will allow personal recovery practitioners and researchers to innovate and identify unique but culturally appropriate care frameworks. We also discuss how the movement can continue to complement existing mental healthcare systems and efforts. Keywords: Asia, legislation, lived experience, mental health services, personal recovery
PREDICCIÓN DEL PRECIO DE MAÍZ EN MÉXICO
Authors: López García María del Rosario , Martínez Damián Miguel Ángel , Arana Coronado José Jaime
Published: December 2021

El maíz (Zea mays) es el cereal más importante en México porque es una parte esencial en la dieta de los mexicanos y tiene importancia económica en producción pecuaria e industrial. Los productores se enfrentan a la volatilidad en los precios del grano y a la falta de información porque en México no existe una señal del comportamiento de los precios futuros de maíz blanco. Bajo la hipótesis de que los precios de Estados Unidos tienen influencia sobre los precios de maíz en México, el objetivo de esta investigación fue construir estimadores de predicción del precio de maíz blanco con series de precios del Estado de México y Sinaloa. Los datos fueron del periodo de 2000 a 2018 y se usó la metodología Box-Jenkins con los modelos, autorregresivo integrado de media móvil (ARIMA), vectores autorregresivos (VAR) y vectores de corrección de error (VEC) con los datos mexicanos y con series de precios de futuros de maíz y precios de maíz en físico de Estados Unidos. Los modelos multivariados proporcionaron pronósticos más cercanos a los valores observados debido a la influencia de los precios de Estados Unidos sobre los precios de México. La capacidad predictiva de los modelos se evaluó con el error porcentual medio absoluto (MAPE) y el coeficiente U de Theil. El modelo VAR proporcionó predicciones del precio en Sinaloa con MAPE y U de Theil menores; en cambio con la serie del Estado de México el modelo ARIMA tuvo pronósticos con valores menores de error porcentual absoluto medio y U de Theil. Entonces, existe influencia de los precios de Estados Unidos sobre los precios de Sinaloa; pero el uso de modelos multivariados no es determinante para obtener pronósticos más cercanos a los valores observados.

Authors:   School of Business and Management Institut Teknologi Bandung, Kamila Mayta
Published: December 2021

Competition between state-owned enterprises (SOEs) and private mining companies are getting bigger and stronger, but state-owned holding companies such as MIND ID have decreased performance due to several factors such as business focus and small business scale. This should be supported by the optimization of resources and the transformation of the competence of each employee to encourage the entrepreneurial spirit. This study was conducted to examine the corporate entrepreneurship culture in three state owned mining companies (PT. ABC, PT. DEF, and PT. GHI) and compared with private mining companies (PT. XYZ, PT. OPS, and PT. RTU). This study uses two methods, Entrepreneurial Orientation Survey (EOS) and Entrepreneurial Leadership Questionnaire (ELQ). EOS is used to measure corporate entrepreneurship culture and ELQ to see entrepreneurial characteristics in expected leadership and actual conditions of its implementation. EOS results show that the corporate entrepreneurship culture of mining SOEs has advantages in Cross-Functionality and Support to New Ideas while private mining companies have significantly higher Speed and Focus dimensions than mining SOEs. The ELQ results show that mining SOEs have the type of leadership in entrepreneurship (Miner type) and the leadership type of private mining companies in Explorer has a higher score than mining SOEs. Mining SOEs are advised to increase the dimensions of corporate entrepreneurship, one of which is by providing scholarships for employees taking magister program and creating a competition program that supports future innovation also the companies should provide training on corporate entrepreneurship.
Defense Diplomacy Strategy in Global Governance to Face the Global Threats
Authors:   Indonesia Defense University, Nurmala Maharani
Published: December 2021

Global developments that are full of dynamics are marked by the emergence of interdependence between countries. Global developments are in line with the development of science and technology which causes countries to seem borderless. The blurring of boundaries between countries and the development of an increasingly dynamic environment are also accompanied by the development of increasingly broad and multidimensional threats. This global development is also marked by the emergence of new actors in international relations. The development of threats and increasing global issues that cannot be handled by the state alone have created a new phenomenon in the international relations order, namely global governance. Previously, the state was the sole actor in the order of international relations. However, with global governance, there is a new arrangement in the international relations system that accommodates all actors who play a role. This research will use a qualitative phenomenological method. The theory used in this research are global governance, defense diplomacy and international organization as a basis theory and concept, and also a security theory as supporting theory. In the end, we can see that the change of international order can bring the positive effect for countries in achieving their national goals and accomplish their national interests.

Araştırma Türkiye Cumhuriyeti Merkez Bankasının (TCMB) gerçekleştirmeye hazırlandığı Dijital Türk Lirası (DTL) kullanım kabulü ve kullanımıyla ilgili bir sistem önerisi içermektedir. Araştırma nitel veri analiz yöntemlerinden yarı yapılandırılmış derinlemesine görüşme tekniğiyle gerçekleştirilmiştir. Çalışmaya konusu itibariyle ekonomi ve finans alanında 10 uzman öğretim üyesi ve öğretim elemanı dahil edilmiştir. Blokzincir ve DTL hakkında çok sayıda kişinin bilgi sahibi olmaması nedeniyle araştırmada kartopu örnekleme yöntemi kullanılmıştır. Çalışma gelecekte DTL’nin piyasaya entegre olmasıyla birlikte şirketlerin daha uygun maliyetler ile borçlanabilmesini sağlamayı planlarken yatırımcılarında spekülatif ve kırılgan yapılara sahip kripto para ve token piyasalarından ziyade arkasında belirli bir değeri olan varlıklara yatırımlarının kaydırılmasını sağlayarak Türkiye ekonomisine katkı sunulması hedeflenmiştir. Çalışmanın önerileri arasında şirketlerin çıkaracağı tokenler yani Dijital Türk Akçelerinin ve bu akçelerin işlem görebilecekleri Dijital Türk Akçesi Borsası özelinde sistem önerilmiştir. Araştırmanın verileri incelendiğinde ise uzmanların büyük çoğunluğu önerilen söz konusu sistemin gerekli finansal ve hukuki düzenlemeler ile gelecekte şirketlerin borçlanmalarında kullanılabilecek bir yöntem olarak görmüştür. Bu bağlamda çalışmanın dijital para alanında keşfedici bir araştırma niteliğinde olup literatüre Dijital Türk Lirası (DTL), Dijital Türk Akçesi (DTA), Dijital Türk Akçesi Borsası (DTAB) ve yeni dönemde şirket borçlanmalarında uygun maliyetli bir sistem önerisiyle literatüre mütevazı bir katkı sunması beklenmektedir. DTL çalışmaları olumlu sonuçlandıktan sonra kullanımına yönelik uygulamalar hayata geçtikçe bu alandaki çalışmaların artacağı düşünülmektedir.

Purpose. Regarding the area of maize in Hungary, we can state that it is one of the largest crops grown in the area. Maize was grown on 1,048,070 hectares in Hungary in 2019. The purchase price depends, among other things, on the size of the sown area and the yields, but many other things can also have an impact in either a positive or negative direction. In recent years, the purchase price of maize has been around HUF 50,000/tonne. Maize is one of the heat-demanding plants that needs 500 mm of rainfall during its growing season to develop smoothly. The expected yield is significantly influenced by the type of soil grown. Meadow chernozem and brown forest soil are the most favorable for maize.

Methods. The maize was sown on April 17, 2020. In the experimental area were selected 5 squares. A square has a floor area of 4 m2. In the research area were conducted three weed surveys. The dates were: May 18, June 22, and July 29, 2020. The following herbicides were released on 15th May: Sulcotrek (sulcotrione and terbuthylazine); Tegoplant (trisiloxane); Trend (adjuvant).

Results. The area was harvested on 21 September by a combine harvester equipped with a corn tube breaker adapter. From an area of one hectare, 9.4 tons of crops were harvested with a moisture content of 14%.

Conclusions. In the case of chemical weed control, it is recommended to use an agent or combination which is specifically aimed at reducing unwanted, in this case pine sorghum.

Purpose. To study the quality formation in bread from different flour of spelt wheat (premium, whole-wheat) depending on the variety and line.

Methods. Laboratory, mathematical and statistical, physical and chemical.

Results. The bread volume made from high-grade flour varied from 303 to 523 cm3, which corresponds to 1.0–7.6 points depending on the variety and line of spelt wheat. The bread volume made from whole-wheat flour was 10–20% less than the bread volume made from premium flour. The average bread volume obtained from whole-wheat flour of ‘Zoria Ukrainy’ variety was 470 cm3, while low bread volume was obtained from flour of ‘Shvedska 1’ variety and LPP 3132, LPP 3117, TV 1100 lines which corresponded to 2.8–3.2 points. In other varieties and lines, these indicators were very low and ranged between 270 and 328 cm3 or less by 142–200 cm3 compared to the standard variety. The convexity of pan bread made from high-grade flour was the highest in ‘Zoria Ukrainy’ spelt wheat variety and NAK 34/12‑2 line: 0.49 and 0.54, respectively, which corresponded to 5.0 points. Significantly higher indicators were found in P 3, NAK34/12–2, and LPP 3122/2 lines: 0.38–0.51 (1.0–5.0 points). In ‘Shvedska 1’ variety and five lines, the indicator of bread convexity varied from 0.27 to 0.37 (from 3.0 to 4.0 points). In other varieties and lines it was significantly lower (0.07–0.21) than in the standard. The indicator of bread convexity from whole-wheat flour in ‘Zoria Ukrainy’ spelt wheat variety was 0.37 which corresponded to 4.0 points. Significantly higher indicators were found in P 3, NAK34/12–2 and LPP 3122/2 lines: 0.38–0.51 (1.0–5.0 points). In ‘Shvedska 1’ variety and five lines, the bread convexity indicator varied from 0.27 to 0.37, that corresponds to 3.0–4.0 points). In other varieties and lines it was significantly lower (0.07–0.21) than in the standard. Culinary quality of bread was high in all samples: 7.2–8.4 points (80–93% of the maximum value). However, the highest quality had the bread made from ‘Zoria Ukrainy’ variety, LPP 3132, NAK34/12–2, and TV 1100 lines. The overall culinary quality of whole-wheat bread was very high as it varied from 8.3 to 9.0 points. However, the bread made from ‘Shvedska 1’ variety and LPP 3117, LPP 3122/2, P 3, LPP 3132, NAK34/12–2 lines had the highest quality (9.0 points).

Conclusions. Gloss index of bread surface and its overall estimate is affected by the protein content in grain. Gluten content has a slightly smaller effect on bread quality. In addition, crust surface, bread texture, the overall estimate of bread quality is also affected by the gluten deformation index. Bread obtained from ‘Zoria Ukrainy’ flour, LPP 3132, NAK34/12–2, and TV 1100 lines had the highest overall culinary evaluation.

Authors: Mandrovska S. M.
Published: December 2021

Purpose. To determene the productivity of switchgrass (Panicum virgatum L.) agrophytocenoses under the long-term use.

Methods. Field, statistical, calculation and comparative.

Results. During long-term switchgrass cultivation, the lowest yield was obtained in the first vegetation year: 19.7 t/ha in the control treatment, 25.3 and 17.5 t/ha in the experimental treatments. The average raw biomass yield was as following: 30.3 t/ha in the control (variety ‘Cave-in-Rock’), 32.6 t/ha and 26.5 t/ha in the experimental treatments (varieties ‘Kanlow’ and ‘Morozko’, respectively). The yield of solid biofuel (17.3 t/ha) indicates the advantage of ‘Kanlow’ over the control (11.7 t/ha). The lowest yield (15.7 t/ha) was obtained from ‘Morozko’ variety. The energy yield over the treatments: 312.8 GJ/ha in the control, 397.5 and 367.2 GJ/ha in the experimental treatments, respectively. The cost of the grown production was as following: 416.03 UAH/t in the control (‘Cave-in-Rock’), 312.01 UAH/t in ‘Kanlow’, and 366.42 UAH/t in ‘Morozko’. The profitability of the control (‘Cave-in-Rock’) was 69.5%, ‘Kanlow’ – 101.4%, ‘Morozko’ – 66.8%. Economic evaluation of the productivity of switchgrass agrophytocenoses resulted in the following ranking: ‘Kanlow’, ‘Cave-in-Rock’, ‘Morozko’. When analyzing the energy equivalent of switchgrass biomass production and energy consumption, it was found that ‘Kanlow’ yielded 588.8 GJ/ha and the control – 468.3 GJ/ha, which is lower by 120.5 GJ/ha.

Conclusions. The yield of switchgrass agrophytocenoses on average over the years of research (2014–2019) was 30.3 t/ha in ‘Cave-in-Rock’ (the control), 32.6 t/ha in ‘Kanlow’, and 26.5 t/ha in ‘Morozko’. The energy equivalent of the obtained yield was 468.3 GJ/ha in ‘Cave-in-Rock’ and 588.8 GJ/ha in ‘Kanlow’, which is by 120.5 GJ/ha higher than in the control.

Purpose. Establish the impact of basic tillage and weed protection measures on soil density in winter wheat and sugar beet crops. Investigate the criteria for the formation of winter wheat and sugar beet productivity depending on weather conditions, measures of basic tillage and protection against weeds.

Methods. Field, laboratory.

Results. Soil density for the period of winter wheat harvesting for plowing to a depth of 20–22 cm and direct sowing was in the same range at the level of 1.22 and 1.23 g/cm3, which can be explained by the peculiarity of the soil and the root system of the plants themselves. In sugar beet crops, the combination of plowing to a depth of 25–27 cm with subsequent shelfless loosening at 34–36 cm makes it possible to maintain the density of the arable soil at the level of equilibrium for this type of soil. In other treatments, the soil density increases to 1.27 and 1.28 g/cm3, with compaction of the upper 0–10 cm layer of soil to 1.25 g/cm3 for plowing by 30–32 cm and 1.29 g/cm3 – for shelf-free loosening by 34–36 cm, which has a negative impact on the productivity of sugar beets.

Conclusions. With the optimal sowing period for the conditions of Kyiv region on September 12–15, the most optimal sowing rate remains 4.5 million units. nas./ha, for increase in density of standing of plants we note lodging of plants and damp years and essential shortage of grain in arid. According to our research, the main tillage for winter wheat plowing by 20–22 cm remains the most rational for obtaining stable yields of winter wheat (yield was 5.03 t/ha). At the same time, good predecessors of peas for grain, rape, buckwheat can be used direct sowing with the introduction of herbicide continuous action Roundup, 48% v.r. 3.0 l/ha. The highest productivity of sugar beets was obtained by using the main tillage plowing by 25–27 cm + shelfless loosening by 34–36 cm yield of root crops at the level of 52.13–51.73 t/ha, sugar content – 14.80–14.83%, sugar harvest – 7.73–7.81 t/ha. On deep medium loam chernozems, this tillage allows to ensure optimal agrophysical indicators of the soil, remove the plow sole, earn crop residues and ensure yields in arid conditions. Application of sugar-free loosening to sugar beets to a depth of 34–36 cm reduces the yield of root crops by 5.32 and 7.20 t/ha compared to plowing to a depth of 30–32 cm, which is associated with an increase in weediness of crops and soil density.
