The kinetics of reaction of C2H5OH with N2O behind shock waves is studied. The quantitative measurements of the time profiles of concentration of O atoms were carried out by the method of atomic resonance absorption spectroscopy (ARAS) using resonance vacuum-ultraviolet line of O-atom at 130.5 nm. For the calibration of absorption intensity of oxygen atoms depending on its concentration, the special series of experiments in the mixture containing different amounts of N2O in Ar was carried out at T = 2100 ± 50 K when molecule of N2O is completely dissociated. An experimental study of the appearance and consumption of oxygen atoms during the reaction of ethanol with oxygen in mixture 10 ppm N2O + (10 ... 0.1) ppm C2H5OH + Ar at temperatures of 16002300 K and pressures of 200-300 kPa have been carried out. A kinetic analysis of obtained data was performed using the Chemkin package.

Faunistic review of amphibians in protected areas of Ukrainian Roztochia
Authors:   Ivan Franko National University of Lviv, Andriishyn B. O.
Published: December 2020

Background. Study of amphibian fauna as a necessary component of ecosystems is always relevant and requires a regular renewal of information, especially in protected areas. We conducted a field investigation of amphibians, a literature review and an inventory of the collections of herpetological funds in relation to three protected areas: the Roztochia Biosphere Reserve, the Yavorivskyi National Park, and the Cholgini Ornithological Reserve. Materials and Methods. The field study was performed by classical methods: route method with manual catching and with herpetological nets, vocalization method, sampling of amphibians crushed on the road, and catching individuals with frog fences. We also analyzed the literature and amphibian collections in the Zoological Museum of Ivan Franko National University of Lviv. Results. According to the available literature, the amphibian fauna of these three areas under protection is similar and typical of this region. The results of our field research slightly differ from the literature data, thus, there is a need for further studies. On the study areas, we found 12 species of amphibians, which is more than half of the number of amphibian species in Ukraine, in particular: Smooth Newt Lissotriton vulgaris, Great Cres­ted Newt Triturus cristatus, Fire-bellied Toad Bombina bombina, Eastern Tree Frog Hyla orientalis, Common Spadefoot Toad Pelobates fuscus, Common Toad Bufo bufo, Green Toad Bufotes viridis, Common Frog Rana temporaria, Moor Frog Rana arvalis, Marsh Frog Pelophylax ridibundus, Edible Frog Pelophylax esculentus and Pool Frog Pelophylax lessonae. We detected 2 species of Caudata and 10 species of Anura. 10 species of amphibians were found in the Roztochia Biosphere Reserve, 5 species – in the Yavorivskyi National Park, and 9 species – in the Cholgini Ornithological Reserve. Conclusions. According to the field results, 4 species inhabit all three protected areas – Common Toad, Eastern Tree Frog, Marsh Frog and Edible Frog. A relatively small variety of amphibians found in the Yavorivskyi National Park can be due to the homogeneity of habitats and a proximity of one of the largest military proving grounds in Europe, which limits amphibians in choice of the reproductive and trophic habitats. These habitats deserve special attention because of their fast degradation for the last 10 years.

The solvents to be compatible with polymethylmethacrylate (PMMA) were selected on the basis of qualitative and quantitative criteria. The features of the solvent bonding connecting seam of the irreversible bonding PMMA of various trademarks have been studied. It is shown that the method of solvent bonding with vinylacetate can be an alternative to adhesive bonding when sealing microchips since the solvent bonding connecting seam makes a smaller contribution to the change in the working volume of microstructures.
The weak ring of COVID-19: Elderly population
Authors: AISDL
Published: December 2020

The epidemic, which first appeared in Wuhan, China in December 2019 and spread to all continents in a short time, affected every nation in different dimensions. Although Covid-19 does not discriminate between individuals, it poses a heavy burden in the disadvantaged group in terms of the course of the disease and causes of death. Deaths in those with additional diseases and intensifying the age of 65 show that the epidemic is targeting a specific population. Therefore, pandemic-based elderly mortality rates are aimed to be seen more clearly with an international comparative table by considering a wide range of old age and other indicators. In this context, 85 countries with more than 5000 cases until September 25 were selected to the sample group. Cluster analysis was used to understand whether there is a relationship between Covid-19 case / death rates and the aging processes of countries. The relationship of the 5 clusters that emerged as a result of this, with the elderly mortality rates caused by Covid-19, was taken into the center and the relationship between Covid-19/Elderly-Death was understood more clearly when international comparisons were made. It was determined that elderly deaths from Covid-19 decreased from the oldest first cluster to the youngest cluster. In addition, elderly deaths from Covid-19 were higher in developed countries than in undeveloped countries. Potential support rate was low where deaths associated with Covid-19 were concentrated. Access to clean water, healthcare spending, and the proportion of female cabinet representatives were found to be weakly associated with deaths from Covid-19. Multiple Linear Regression Analysis was conducted to examine the relationship between epidemic mortality rate of the elderly and 11 factors consisting of socio-economic, health and political indicators. As a result, it was found to have a positive intermediate variance between Covid-19-related elderly mortality and other data. In the last part of the study, the Covid-19 outbreak in the capture and death rates of the elderly population in Turkey compared to other countries and assessed the current outbreak management.

Published: December 2020

Intelligent Tutoring Systems are a genre of highly adaptive software providing individualized instruction. The current study was a conceptual replication of a previous randomized control trial that incorporated the intelligent tutoring system Native Numbers, a program designed for early numeracy instruction. As a conceptual replication, we kept the method of instruction, the demographics, the number of kindergarten classrooms (n = 3), and the same numeracy and intrinsic motivation screeners as the original study. We changed the time of year of instruction, changed the control group to a wait-control group, added a maintenance assessment for the first group of participants, and included a mathematical language assessment. Analysis of within- and between-group differences using repeated measures ANOVA indicated gains of numeracy were significant only after using Native Numbers (η_p^2 = .147). Results of intrinsic motivation and mathematical language were not significant. The effect size of numeracy achievement did not reach that of the original study (η_p^2 = .622). Here, we compared the two studies, discussed plausible reasons for differences in the magnitude of effect sizes, and provided suggestions for future research.

Falsification of string theory - Thermal effects of quantum radiation
Authors: Chen Wen-Xiang
Published: December 2020

We know that string theory is purely geometric.It believes that, through the holographic principle, quantum effects can be generated by projecting onto the lower dimensional multidimensional geometry.There is a corollary here that quantum radiation cannot produce thermal effects.In this paper, in the case of superradiation, the boson boundary condition is presupposed first, which is possible to obtain higher energy than the traditional quantum effect, while the extra energy belongs to the classical domain, namely heat.
Autistic adult and non-autistic parent advocates: Bridging the divide
Authors: Gernsbacher Morton Ann , Rottier Helen
Published: December 2020

Purpose: Due to the developmental nature of autism, which is often diagnosed in preschool or elementary school-aged children, non-autistic parents of autistic children typically play a prominent role in autism advocacy. However, as autistic children become adults and adult diagnoses of autism continue to rise, autistic adults have played a more prominent role in advocacy. The purpose of this chapter is to explore the histories of adult and non-autistic parent advocacy in the United States and to examine the points of divergence and convergence. Approach: Because of their different perspectives and experiences, advocacy by autistic adults and non-autistic parents can have distinctive goals and conflicting priorities. Therefore, the approach we take in the current chapter is a collaboration between an autistic adult and a non-autistic parent, both of whom are research scholars. Findings: The authors explore the divergence of goals and discourse between autistic self-advocates and nonautistic parent advocates and offer three principles for building future alliances to bridge the divide between autistic adults and nonautistic parents. Implications: The chapter ends with optimism that US national priorities can bridge previous gulfs, creating space for autistic adult and non-autistic parent advocates to work together in establishing policies and practices that improve life for autistic people and their families and communities.
Whether and how semantic similarity impairs short-term memory: A test with a new index of semantic similarity
Authors: Ishiguro Sho , Saito Satoru
Published: December 2020

Semantic similarity appears to have a facilitative effect on short-term memory (STM), which contrasts with the detrimental effects of phonological and visual similarity on STM. Given that STM theories generally posit detrimental effects of similarity, it is theoretically and empirically important to test the semantic similarity effect. Recently, a review study proposed that semantic similarity per se would have a detrimental effect while semantic association and additional retrieval cues, which are facilitative of STM, would work as confounding factors for the semantic similarity effect. The present study tested this view by minimizing the influence of these possible confounding factors in the experiment and by utilizing a new index of semantic similarity in the analysis. The results of the present study indicated that the semantic similarity indeed had a detrimental effect on immediate serial recall correct-in-position scores. An examination based on two other scoring methods (i.e., item correct and absolute order errors) further suggested that the locus of the detrimental effect of semantic similarity is in order memory. In addition, other semantico-lexical variables (e.g., word length, frequency, and imageability) were also analyzed. Patterns of these variables’ effects on item memory were complementary to the effect of semantic similarity on order memory. From a theoretical point of view, as the detrimental effect of semantic similarity demonstrated by the present study is comparable to phonological and visual similarity effects, this finding implies a store based on semantic information or a general process for various types of information.

Published: December 2020

Background: Blood transfusion is an integral part of patient management. Good transfusion practice guided by standard protocols is considered ideal for optimal use of resources and manpower. Cross-match requests disproportionate to the actual requirement causes overestimation of blood usage and potential wastage. This study aims to determine the crossmatch, transfusion, and utilization rates for blood using transfusion index, and cross-match to transfusion ratio in the various departments of the hospital for the evaluation of transfusion practices.

Materials and Methods: A retrospective study was conducted using the records from the hospital blood bank for 12 months to obtain transfusion and cross-match records from various clinical units. Transfusion requests, units cross-matched, and completed transfusions were used to calculate the cross-match to transfusion ratio, and transfusion index for each department.

Results: A total of 5156 units of blood were cross-matched for 3437 transfusion requests, out of which 3752 were transfused, giving a mean cross-match to transfusion ratio of 1.37. The non-usage of blood was 27.2% and the transfusion index stood at 1.09. The cross-match to transfusion ratio for the individual clinical units ranged from 1.75 (Surgery) to 1.14 (Medicine).

Conclusions: The cross-match to transfusion ratio and transfusion index were within recommended ranges, showing good utilization and low blood wastage. The establishment of a blood ordering protocol via a multidisciplinary approach should be considered to further optimize blood transfusion practices.

Ça roule ! — un pragmatème à décortiquer. Une étude contrastive franco-italienne
Authors: Wylecioł Ryszard , Adamczyk Karolina
Published: December 2020

The aim of this paper is to present, after a short introduction to what pragmateme, or pragmatic phraseologism, is and how we understand it as a fixed expressive phrase with affective and emotive load, the results of the Polonium project entitled “Pragmatemes in contrast: from linguistic modeling to lexicographic coding”. In particular, we want to divulgate information concerning analysis of the French pragmateme Ça roule ! and its Italian corresponding phrase A posto!. Furthermore, equivalents of both pragmatemes are also investigated. However, as we consider cognitive linguistics tools as those which may give greater response to what the meaning of pragmatemes is, we broaden the project results with analysis of the trajector-landmark relation and of conceptual metaphors, that are the basis of the imagery for the aforementioned linguistic elements. In this way, we may also try to discern similarities and discrepancies in how close but still different cultures depict the same scene in similar speech events.
La reduplicación léxica como mecanismo metalingüístico
Authors: Urbaniak Ewa
Published: December 2020

The aim of the present article is to analyse the metalinguistic function of the nominal reduplication in Spanish. The lexical reduplication is a mechanism that consists in repeating a lexical unit within one phrase. The study shows that the nominal reduplication presents metalinguistic functions that reveal the interest of the speakers in a number of semantic issues related to the linguistic categorization and the concept of prototype. What is more, the metalinguistic aspect of the reduplicative constructions play a crucial role in a variety of situations as it entails some intersubjective meanings that are of a great importance for the interaction.
Varijabilnost populacija običnoga bora (Pinus sylvestris L.) na području sjeverozapadnoga dijela Male Kapele prema morfološkim obilježjima iglica i češera

Published: December 2020

U radu je istražena morfološka varijabilnost populacija običnoga bora na području sjeverozapadnoga dijela Male Kapele. Raznolikost i strukturiranost populacija utvrđena je na osnovi deset mjerenih morfoloških značajki iglica i češera, pri čemu su korištene deskriptivne i multivarijatne statističke metode. Provedenim istraživanjem utvrđena je niska varijabilnost morfoloških značajki, a razlike između stabala unutar populacija, kao i između populacija, potvrđene su za većinu istraživanih svojstava. Unutarpopulacijska varijabilnost bila je veća nego međupopulacijska, osim za značajke širina iglice, dužina češera i širina štitića. Istraživanjem je potvrđen i trend variranja populacija po ekološkom principu, kao i specifičan gradijent, odnosno promjena u morfološkoj varijabilnosti s obzirom na promjenu nadmorske visine. Populacije s nižih nadmorskih visina imale su manje češere u odnosu na populacije s viših nadmorskih visina. Osim toga, pionirski karakter običnoga bora u kojega ponekad vrlo mali broj jedinki sudjeluje u osnivanju novih populacija, rezultirao je malom varijabilnošću populacija te njihovom velikom diferencijacijom na tako malom području.

Authors: Mašić Amina
Published: December 2020

U većini europskih zemalja ne postoje pouzdana saznanja o zastupljenosti i ulozi žena u šumarstvu. Lewis (2005) navodi da su u SAD-u, u šumarstvu 1981. godine u tehničkom radu zaposleno 17,5%, a u administraciji 31,8%, 1991. godine je zaposleno u tehničkom sektoru 33,5%, a u administraciji 32,7%. Na Univerzitetu u Sarajevu prva žena stekla je diplomu inženjera šumarstva 1955. godine, iduće godine dvije žene, a 1957. pet žena. Anketno istraživanje provedeno je u cilju utvrđivanja zastupljenosti žena u šumarstvu, kao i pokušaja razumijevanja osnovnih razloga odabira ove profesije, s ciljem eventualnih poboljšanja uvjeta ili motiviranja novih generacija žena u šumarstvu. Uzorak je činilo 78 ispitanica, koje su uposlenice poduzeća: “Bosanskohercegovačke šume” Federalno ministarstvo poljoprivrede, vodoprivrede i šumarstva, Srednjobosanske šume d.o.o. Donji Vakuf, Unsko – sanske šume d.o.o. Bosanska Krupa, Zeničko - dobojske šume d.o.o. Zavidovići, KJP ,,Sarajevo-šume d.o.o. Sarajevo, JPŠ ” Šume Republike Srpske” a.d. Sokolac. Stalno zaposlenih žena sa diplomom Šumarskog fakulteta u Federaciji je 83, a u Republici Srpskoj 151. Samo u Šumama SBK rade žene sa SSS-III stupnja šumarske struke, što ukazuje da ne postoji interes za obavljanje takvog posla. Tijekom studije anketirano je ukupno 78 žena zaposlenih u šumarstvu, od čega je 19 završilo poljoprivrednu ili šumarsku školu, što čini ¼ u odnosu na žene koje su završile druge srednje škole. To ukazuje da je šumarstvo kao struka privlačnije ženama koje su završile druge srednje škole npr. umjetničke škole ili druge tehničke škole. Od 1981.godine šumarstvo postaje interesantnije ženama, od 522 diplomanta, 142 su žene. U Federaciji devet žena se nalazi na rukovodećim pozicijama, a u Republici Srpskoj 21.

The Acquisition and Learning of EFL in A Non-formal English Education in Indonesia
Authors: Rahayu Dwi Ide
Published: December 2020

The acquisition and learning of English as a Foreign Language differs from that of English as a Second Language. In the EFL setting, it is not sufficient if the teaching and learning processes only depend on formal institution. Because of that, the non-formal education plays an important role to support the processes. This research aims at exploring (1) how Kampung Inggris Kebumen – as one of non-formal educations in Indonesia – was built; (2) what the teaching method used to make the learners in Kampung Inggris Kebumen speak English without any reluctance; and (3) how the learners in Kampung Inggris Kebumen acquire and learn English. This research applies qualitative method i.e. a descriptive case study by means of observation and interviews. The result shows that (1) as one of non-formal institution, Kampung Inggris Kebumen plays a significant important role in the success of English teaching and learning in  Kebumen Regency, in terms of their collaboration with MGMP Sekolah; (2)  Kampung Inggris Kebumen applies the combination of direct method and audio lingual method which are confirmed supportive in the process of acquiring and learning English as a Foreign Language; (3) The students feel that they can decrease their affective filter since the instructors of Kampung Inggris Kebumen use many fun learning activities, provide rich exposures, and intensive time to apply the English in students’ real life. Keywords : acquisition, learning, EFL, non-formal education

THE 2017 AMENDMENTS TO THE LAW REFORM (MARRIAGE AND DIVORCE) ACT 1976: A MILESTONE OR A STONE’S THROW IN THE DEVELOPMENT OF MALAYSIAN FAMILY LAW?
Authors: Thambapillay Sridevi
Published: December 2020

The Law Reform (Marriage and Divorce) Act 1976 (LRA) which was passed in 1976 and came into force on 1st March 1982, standardized the laws concerning non-Muslim family matters. Many family issues concerning non-Muslim have emerged ever since, the most important being the effects of unilateral conversion to Islam by one of the parties to the marriage. There has been a lot of public hue and cry for amendments to be made to the LRA. After much deliberation, the Malaysian Parliament finally passed the amendments to the LRA in October 2017, which came into force in December 2018. Although the amendments have addressed selected family law issues, the most important amendment on child custody in a unilateral conversion to Islam was dropped from the Bill at the last minute. Howsoever, at the end of the day, the real question that needs to be addressed is whether the amendments have resolved the major issues that have arisen over the past four decades? Hence, the purpose of this article is as follows: first, to examine the brief background to the passing of the LRA, secondly, to analyse the 2017 amendments, thirdly, to identify the weaknesses that still exist in the LRA, and finally, to suggest recommendations to overcome these weaknesses by comparing the Malaysian position with the Singaporean position. In conclusion, it is submitted that despite the recent amendments to the LRA, much needs to be done to overcome all the remaining issues that have still not been addressed.

Health is one of the main concerns of society. Empirical evidence underscores the growing importance of prevention and health education as a fundamental instrument to improve the quality of public health. Recent health crises, such as Ebola, influenza A, SARS, and Covid-19, have highlighted the importance of communication. When designing communication campaigns during a crisis, the speed of the creation of messages and their effectiveness have relevant social consequences. The objective of this work is to design and develop a mathematical tool, based on Machine Learning techniques, to enable predictions of areas of visual attention quickly and accurately without the use of eye-tracking technology. The methodology combines deep learning algorithms, to extract the characteristics of the images, and supervised modeling mathematical techniques, to predict the areas of attention. Validation is carried out by analyzing various institutional communications from the Covid-19 campaign, comparing the results with the areas of attention obtained using an eye-tracking solution with proven accuracy. The results obtained using the tool in the investigated Covid-19 communication pieces are analyzed, resulting in conclusions of interest for the development of new campaigns.

Resumen
La salud es una de las principales preocupaciones de la sociedad.

Determination of the features and effectiveness of the pivot sprinkler with corner irrigation system
Authors:   L. Pogorilyy UkrNDIPVT, Mitrofanov O. , Sidorenko V. , Sidorenko S.
Published: December 2020

Introduction. Circular-action sprinklers, as shown by the practice of their long-term operation and previous studies, have significant advantages over front-end machines: maintenance is minimized, the ability to fully automate irrigation processes and network power supply, a one-hydrant water supply system, etc. At the same time, pivot irrigation leaves the corner sections of the field without irrigation, which account for up to 20% of its area - and this is a significant drawback of pivot irrigation machines. Foreign manufacturers of irrigation machines produce and sell additional swivel fenders for pivots that irrigate the corners of the field. They are also called "corner irrigation systems". Since 2018, such systems began to appear in Ukraine. Specialists of the South-Ukrainian branch of L. Pogorilyy UkrNDIPVT investigated the corner irrigation system of the company "Valley" by testing in the conditions of economic operation. Research goal. Determination of parameters and characteristics of the corner irrigation system "V-Flex Corner Valley", assessment of its effectiveness and prospects for widespread implementation. Research methods. Theoretical research was carried out by analyzing the studied information resources. Laboratory and field studies were carried out by testing the irrigation system under operating conditions. System parameters and characteristics were determined according to standardized methods. Results. The design features and principles of the irrigation system functioning have been investigated and described. The tests determined the main operational characteristics of the irrigation system in comparison with the characteristics of the pivot sprinkler (using materials from previous studies). The economic indicators of the irrigation system and the circular machine are determined in comparison. The factors of increasing/decreasing efficiency and their quantitative indicators have been investigated. The analysis of the results obtained and the reasons that hinder the widespread introduction of corner irrigation systems into the practice of irrigated agriculture in Ukraine are identified. Сonclusions. Tests and studies of the pivot sprinkler with corner irrigation system have proven the functional excellence and high operational reliability of the irrigation system. The use of a corner irrigation system made it possible to increase the irrigated area by 21.86 % without changing the basic infrastructure and borders of the irrigated field. Implementing a corner irrigation system requires significant capital investment: the cost of a corner wing, which irrigates 21.86 % of the field, is 79 % of the cost of a basic pivot, which irrigates 59.72 % of the field.. The increase in gross income due to an increase in the irrigated area provides a basis for predicting the return on investment when growing highly profitable crops.

Abstract. The work is devoted to the problems of solving the double problem of agricultural engineering (according to the international definition): "Feed the world and save the planet" using the ability to manage the environmental, energy and economic components of agricultural technologies. It was confirmed that the management process sets the conditions: to plan (program), execute, evaluate and continuously act on the creation and improvement of creative agricultural technologies based on the laws of the historical development of the planet's nature (biosphere laws).

The article analyzes the influence of the processes of decomposition of winter wheat straw under the influence of destructors, which are embedded in the soil with implements with different designs of working organs, in the grain-crop rotation of the research field of the South Ukrainian Branch of L. Pogorilyy UkrNDIPVT on productive indicators of production activity, such as the yield of sunflower seeds, the production cost of the resulting products and the profitability of production. The goal of the research is forming and determination of the optimal economically effective system of technical and technological support of farms, when using winter wheat straw for fertilization with its preliminary processing with destructors, which helps to reduce the technogenic load, increase the productivity of the crop production industry and preserve soil fertility in crop rotations on the irrigated lands of south of Ukraine. Research methods – field, quantitative-weight, visual, laboratory and mathematical-statistical. In the crop rotation investigated five systems of basic tillage different in methods, techniques and depth of soil loosening on a background of straw treatment with destructors. Results: it has been established that when growing sunflower in the arid conditions of the southern part of the steppe zone of Ukraine on non-irrigated lands, it is advisable to use winter crop residues for fertilizing, treat it with destructors in combination with ammonium nitrate and plant it in the soil using deep plowing, which creates favorable conditions for its decomposition and formation of seed productivity at the level of 2.58 t/ha. Conclusions: it has been established that the economic effect of the use of destructors with plowing on the 30-32 cm and moldless loosening on the 40-42 cm is several times higher than the additional costs of introducing a destructor and ammonium nitrate. Plowless and shallow tillage and sowing in pre-uncultivated soil proved to be ineffective in an arid Southern climate on non-irrigated lands with a low moisture coefficient, even when treatment with destructors, as a result of which additional costs were received from UAH 0.16 for each hryvnia up to UAH 1.63 loss.

The article is devoted to the study of the influence of the growth-regulating drug Regoplant on the productivity and growth processes of sugar corn in the conditions of the Southern Steppe of Ukraine on dark chestnut soils under irrigation. The aim of the work was to formulate current recommendations for agricultural producers on the use of the growth-regulating drug Regoplant, the selection of hybrids and the scheme of sowing sugar corn, based on the results of field experiments. Materials and methods. Studies to study the effect of the Regoplant preparation, the hybrid composition and the schemes of sowing sugar corn on the productivity of the crop were carried out on dark chestnut slightly solonetzic soils in the Kherson region. The experiment was carried out in four repetitions, in full accordance with modern requirements for the implementation of field experiments in agronomy. Regoplant preparation was used at a dose of 50 ml / ha in the phase of 7-8 leaves. The modern hybrids of the MNAGOR selection - Deyneris F1, Champion F1, NBM-2020 F1 were put to the study. Sowing patterns of the culture - 70 × 10 cm, 70 × 20 cm, 45 × 20 cm, 45 × 30 cm. Growth processes were assessed by the height of the plants in the panicle flowering phase, the crop yield was determined by the mass of marketable ears in wrappers collected from the experimental plot manually and weighed on an electronic analytical balance. Statistical processing of research results was performed at 95 % confidence level in the AgroStat software product. Results. All studied factors influenced the growth processes and productivity of sweet corn. The highest height (185.50 cm) of the crop plants was reached in the variant with the Daenerys F1 hybrid, where the treatment with the Regoplant preparation was not performed, with a seeding pattern of 45 × 30 cm, the minimum plant height was recorded in the areas of the NBM-2020 F1 hybrid with a seeding pattern of 70 × 20 cm and treatment with Regoplant preparation - 125.50 cm. The maximum yield was achieved on the variant with the NBM 2020 F1 hybrid with a seeding scheme of 45 × 30 cm and treatment with the growth-regulating preparation Regoplant in the phase of 7-8 leaves of the culture with a dose of 50 ml / ha - 25, 34 t / ha. The lowest crop yield was obtained on the variant with the Champion F1 hybrid with a seeding scheme of 45 × 30 cm and without treatment with Regoplant - 6.72 t / ha. Conclusions. According to the results of the studies, we consider it expedient to recommend for sowing in the South of Ukraine on dark chestnut soils with irrigation a hybrid of sugar maize NBM-2020 F1 according to the scheme 45 × 30 cm and to process the growth-regulating drug Regoplant in the phase of 7-8 leaves of the culture with a dose of 50 ml / ha. This combination of agrotechnical factors ensured the maximum crop yield in the experiment - 25.34 t / ha of marketable ears in wrappers.
