The research was conducted on the structure and characteristics of the growth of shoots of the genus Viburnum L. There are significant differences in the structure and dynamics of growth within the genus, so the determination of the structural features of the shoots of species of the genus Viburnum is relevant. The research of the dynamics of shoot growth was carried out according to the method of A.A. Molchanov and V.V. Smirnov (1967). The species studied by us belong to three sections of the genus Viburnum; the peculiarities of buds structure generally determine the structure of the shoots in the species of each section. It was found that the type of each of the three sections of the genus is characterized by a special structure of the shoots. It has been studied the rhythm of growth and development of native and introduced species of the genus Viburnum L. The terms of shoots growth of the species of the genus were analyzed, and the length of the annual growth of shoots was determined. Phenological date of the beginning and end of shoot growth was established. It was revealed that the onset of individual phenophases quite clearly correlates with the sum of effective temperatures above 5 ° C. The species of the genus Viburnum are characterized by the following types of shoots: tillering, stem, generative. Intensive growth of shoots of all studied species occurs in May - mid-June. In the species of the section Lantana, there are 2 peaks of shoot growth - May and mid-July. According to the duration of growth of shoots, viburnum can be divided into two groups: 1) with a short period of growth (65 - 75 days): V.opulus L., V.sargentii Koehne, V.prunifolium L., V.rufidulum Raf., V.lentago L; 2) with a long period of growth (100 or more days): V.lantana L., V.carlesii Hemsl., V.veitchii C.H. Wright, V.rhytidophyllum Hemsl., V.buddleifolium C.H. Wright, V.burejaeticum Rgl. et Herd. The data obtained demonstrated that the greatest annual growth of all Viburnum species was recorded at the age of 4-7 years. A decrease in the annual growth of axial shoots states the need for works on preliminary rejuvenation of the bush.

Purpose. To establish the optimal row spacing and so­wing rate of sorghum seeds of grain varieties ‘Dniprovskyi 39’ and ‘Vinets’, to substantiate their influence on the growing season and biometric parameters of plants in the Right-Bank Forest-Steppe of Ukraine. Methods. Field, laboratory, mathematical and statistical. Results. The most intensive growth and development of sorghum plants was observed when sowing seeds with a row spacing of 45 cm and a seeding rate of 200 thousand pieces/ha. In particular, the duration of the growing season under such conditions was the smallest: 108 days for the ‘Dniprovskyi 39’ variety and 106 days for the ‘Vinets’ variety. At the same time, the indicators of field seeds germination, plant height and stem diameter were maximum in the experiment: ‘Dniprovskyi 39’ – 88.7%, 137.3 cm and 1.7 cm, ‘Vinets’ – 86.9%, 121.8 cm and 1.6 cm, respectively. It was found that an increase in seeding rate reduced indicators of productive tillering, leaf area and weight per plant. The most intense tillering of sorghum plants was observed at a seeding rate of 150 and 200 thousand pieces/ha for all the studied variants of the row spacing: on average, up to two panicles well filled with grain per plant, depending on the varietal characte­ristics. At the rate of 250 thousand pieces/ha, tillering of plants in both varieties was somewhat weaker – 1.0–1.1 panicles per plant. The largest indicators of leaf surface area and weight of one plant were with a row spacing of 45 cm: 1528–2320 cm2 and 169.2–185.6 g in the variety ‘Dniprovskyi 39’ and 1476–2180 cm2 and 143.1–162.3 g in the variety ‘Vinets’ depending on planting density. Reduction of row spacing up to 15 cm and its increase up to 70 cm led to a decrease in the main parameters of plant growth and development. Conclusions. Sorghum plants developed better when sown with a row spacing of 45 cm and a seeding rate of 200 thousand pieces/ha, which were recommended for growing crops in the conditions of the Right-Bank Forest-Steppe of Ukraine.

Purpose. To establish the peculiarities of growth and development and formation of productivity of Savoy cabbage varieties (Brassica sabauda Lizg.) in the conditions of the Right-Bank Forest-Steppe of Ukraine. Methods. The research was conducted in the Research and Production Department of Uman National University of Horticulture in the years 2018–2020. Varieties of savoy cabbage (‘Vertu 1340’ – control, ‘Sphere’, ‘Rozali’ and ‘Vertus’) were planted according to the scheme 70 × 40 cm (35.7 thousand plants/ha). Results. During the sowing of seeds (April 25) on cold ridges in a row method with a row spacing of 10 cm, mass shoots of Savoy cabbage were observed on average in early May (7–8 days), the beginning of head formation – in the middle of August, and their technical maturity in late September. Intensive growth of heads took place in the middle and late August and ended in late September. On average, over the years of research, the largest diameter of the head was observed in the cultivars ‘Vertu 1340’ – 18.7 cm, the smallest in the ‘Rosalie’ – 16.1 cm. at one level – 17.5 and 17.6 cm, respectively. The smallest in height at the level of the rosette and head were plants of the ‘Sphere’ and ‘Vertus’ varieties – 25.4 and 23.4 cm and 26.9 and 24.6 cm, respectively. The control variety ‘Vertu 1340’ was characterized by the highest indicators of height of both the rosette (40.7 cm) and the actual head (36.5 cm). Slightly lower rates were observed in the variety ‘Rosalie’ – 32.9 and 31.8 cm, respectively. The highest yields were formed by Savoy cabbage varieties ‘Vertus’ (53.1 t/ha) and ‘Sphere’ (51.8 t/ha), which exceeded the control variant by 7.4 and 6.1 t/ha, respectively (‘Vertu 1340’ – 45.7 t/ha). The least productive among the studied assortment was ‘Rosalie’ yielding 39.9 t/ha. Conclusions. When grown in the Forest-Steppe of Ukraine, the highest yields of marketable products are formed by Savoy cabbage varieties ‘Sphere’ and ‘Vertus’.

As a result of the long-term (2011-2018) researches in plum orchards the intensity types of the plum fruit moth butterflies flight seasonal dynamics – low, normal and high have been established which are observed during the vegetation period. The two latters are dangerous for crop so they are problematic for producers and require the flight dynamics control. The weather conditions indicators have been systematized. The mathematical parameters have been determined between those indices and the insect imago population density. The types of intensity of the seasonal flight dynamics (low, normal, and high) that can be observed during the vegetation period have been established. The onset of the imago flight of the plum fruit moth after overwintering at the normal intensity is observed under the sum of effective temperatures (SET) of 80.9 and precipitations up to 33.1 with a probability of 0.545, whereas at high the intensity these indicators were 116.0 °C, 26.3 mm and 0.273 respectively. As for the generation which overwintered the usual flight type of G. funebrana Tr. has been noted at SET 332.7, precipitations 44.8 with a probability of 0.636, and high type, at 410.1 °C, 37.5 mm and 0.182 respectively. The summer generation under the normal intensity developed at SET 710.7, precipitations sum 48.3 and probability 0.555, at high intensity, 604.3 °C, 52.6 mm and 0.364 respectively. In the right-bank part of the Western Forest-Steppe of Ukraine, the imago flight began at the end of April – in the beginning of May. The imago flight ends mostly at the end of September but may last until mid-October when autumn is warm. The average number of the butterflies of the generation wich overwintered under normal and high intensity types, varied to 15.1 and 20.9 respectively, and in the summer generation decreased to 7.8 and 10.5 specimens. Under the low intensity type, the amount of imago after wintering average at 5.0 and for the summer generation 5.8 specimens. The maximum G. funebrana density after wintering under the normal and high types of flight intensity was 19.4 and 30.1 and for the summer generation 15.7 and 27.1 specimens respectively. These figures under the low flight intensity for the both generations were 8.7 and 5.9 specimens respectively. The analysis of variance showed that the average imago number in traps (56.9 %) was determined by the intensity type, the generation share was 24.7 %, and the interaction between the two factors was within 12.6 %. The maximum imago trapping rates depended mainly on the intensity type – 90 %, and the other factors proportions studied were 3.3 and 6.7 %.

Introduction of an important importance acquires issues of drought resistance of plants that are closely linked to the problems of studying the water regime. The main negative consequence of modern warming is drought. Therefore, we have been conducted by drought resistance to G. biloba and its varieties of G. biloba 'Mariken' and 'Troll', which were compared with the indicators of the water mode of the aboriginal leaves for the Right-Bank of Forest-Steppe of Ukraine species Carpinuз betuluз L. and Acer platanoideз L. Determination of the actual and potential drought resistance of the plant studied was carried out with the help of field and laboratory techniques. It is found that all G. biloba plants are characterized by high actual drought resistance. G. biloba plants by most of the water regime exceeds the value of aboriginal species C. betuluз and A. platanoideз. This indicates a high degree of acclimatization and wide plasticity G. biloba to the conditions of introduction.

Purpose. The aim of the study was to identify samples of chickpeas with economically valuable traits on the ground of the basic collection of parent material as a source of traits for breeding in conditions of the Right-Bank Forest-Steppe of Ukraine; to systematize them by yielding capacity, elements of crop structure, duration of the growing season, morphological features, areas of use in accordance with the two main groups of culture morphotypes – kabuli and desi – in order to plan areas of breeding. Methods. Field (conducting phenological observations), laboratory (assessment of the studied material). Results. 223 samples of chickpeas originating from different countries of Asia and Europe were screened in order to determine their breeding value in conditions of the Right-Bank Forest-Steppe of Ukraine. It is established that promising for selection in such conditions are samples originating from Russia, Syria and India, as well as varieties and new highperformance lines obtained from Plant Breeding and Genetics Institute – National Center of seed and cultivar investigation of NAAS of Ukraine, characterized by a set of features such as grain productivity (number of beans per plant, weight of 1000 seeds and others), and suitability for the mechanized harvesting (height of the plant, height of attachment of the lower bean and others). The studies were conducted in contrasting conditions of two years, 2018 and 2019, which differed significantly in the amount of precipitation and the sum of effective temperatures, and the nature of their distribution during the growing season, which allowed to obtain more objective information about breeding material. The nature of variability of the main economically valuable traits by groups of morphotypes as well as correlations between them is determined, this will allow to make targeted selections in breeding for the above mentioned traits, using this experimental material as genetic sources. Conclusions. A set of chickpea samples of different ecological and geographical origin with valuable breeding traits have been identified, which can be used as genetic sources in practical selection to create new varieties with specified parameters in conditions of the Right-Bank Forest-Steppe of Ukraine. The selected sources were unique in one feature as well as combined a set of features.

In carrying out an investigation into the explosion, among others, the investigative version of the use of a single-use reactive grenade launcher is being considered. The most common for criminal explosions are applied grenade launchers RPG-18, RPG-22, RPG-26. Their use is due to a number of such properties as small size and weight, which makes it possible to transfer them covertly, the range of the shot significantly exceeding the range of the hand grenade throw, the high detonating effect of the rocket grenade explosion. The single-use rocket launchers are generally of the same design. Their differences are in the features of the components construction and dimensional characteristics, which are given in the article. On the basis of expert practice, details ofgrenade launchers that remain at the site of the explosion and have the least damage are determined. These details are the objects of investigation of the explosion technical expertise. These objects include launchers of grenade launchers and rocket parts ofjet grenades. The design features of the launchers, their dimensional characteristics and marking symbols make it possible to determine their belonging to a specific type of jet grenade launchers. Missile parts of jet grenades differ in the form of the combustion chamber of the jet engine, nozzle, in the size ofthe outlet section of the nozzle, in the form and size of the stabilizerfeathers. To determine the belonging of the rocket part of the grenade to a specific type ofjet grenade launcher, it’s necessary to establish a set of structural features and dimensional characteristics. At considerable damage of the combustion chamber of the jet engine, as a rule, the nozzle block remains intact that allows to define diameter of critical section of a nozzle, and on it to establish type of the used single-use grenade launcher.

Choice of profession is a social phenomenon that every person has to face in life. Numerous studies convince us that not only the well-being of a person depends on the chosen work, but also his attitude to himself and life in general, therefore, the right and timely professional choice is very important. Research about factors of career self-determination of students of higher education institutions in Ukraine shows that self-determination is an important factor in the socialization of young person, and the factors that determine students' career choices become an actual problem of nowadays. The present study involved full-time and part-time students of Institute of Philology and Mass Communications of Open International University of Human Development "Ukraine" in order to examine the factors of career self-determination of students of higher education institutions (N=189). Diagnostic factors of career self-determination of students studying in the third and fourth year were carried out using the author's questionnaire. Processing of obtained data was carried out using the Excel 2010 program; factorial and comparative analysis were applied. Results of the study showed that initial stage of career self-determination falls down on the third and fourth studying year at the university, when an image of future career and career orientations begin to form. At the same time, the content of career self-determination in this period is contradictory and uncertain, therefore, the implementation of pedagogical support of this process among students is effective.

Розвиток проаналізовано як категорію,  явище і проблему психології розвитку в різних аспектах аналізу. Розглянуто місце розвитку в системі  споріднених психологічних понять. У статті також аналізуються психологічні аспекти теоретичних та  методологічних  постнекласичних  тенденцій  вивчення  природи,  характеру  та  визначення  психічного  розвитку. Постнекласична парадигма та плюралістична методологія пізнання визначають розмитість  дисциплінарної мови  та  врахування  ролі  соціокультурного  контексту  при  вивченні  психологічних явищ.  Важливими тенденціями сучасного теоретико-методологічного стану психологічних досліджень розвитку  також є визнання неефективності моністичного підходу до його вивчення, взаємозв'язок теоретичних ідей  та   спроби   створення   метатеоретичних   схем,   постнекласичне   розуміння   розвитку   як   принципово  незавершеного   процесу   саморуху,   актуалізація   антропологічного   діапазону   проблем   та   посилення  спрямованості на роль культурного контексту в дослідженні розвитку людини.  The article deals with the modern approaches to the interpretation of the category of development, reveals  the theoretical and methodological approaches to study of development in modern psychology, its psychological  content, patterns, structure and dynamics. Category of development is viewed as an epicenter of scientific issues in  modern  psychology  and  the  concept  of  the  integrative  type.  Category  of  development  is  considered  as  the  phenomenon  and  the  problem  of  developmental  psychology  in  various  aspects  of  the  analysis.  Analyzed  the  development site in the related psychological concepts. The article analyzes the psychological aspects of theoretical  and methodological postnonclassical contemporary trends in the study of nature, character, and determination of  mental  development.  Postnonclassical  paradigm  and  pluralistic  methodology  of  knowledge  determine  the  disciplinary blurring and increase of the role of the analysis of socio-cultural context in the study of psychological  phenomenon. The important tendencies of modern theoretical and methodological state of psychological researches  of development are facts of inefficiency of the monistic approach to its study, interconnection of theoretical ideas  and   attempts   of  creating   metatheoretical   schemes,   postnonclassical   understanding   of   development   as   a  fundamentally  uncompleted  process  of  self-motion,  actualization  of  anthropological  range  of  problems  and  strengthening of focus on the role of cultural context in research of human development.
