Published: January 2024

Bishnu Prasad Rabha has been an accomplished musician, creative writer, acclaimed master of fine arts, social activist and politician. His contribution to Assamese social and cultural life is great. When we talk about modern Assamese music, we need to mention the name of the musician par excellence Bishnu Prasad Rabha. His contribution to modern Assamese lyrical literature is great. Bishnu Prasad Rabha was a profound composer and musician of his times. He has numerous songs to his credit which speak of the aspirations of the Assamese community at large. Whether be it a romantic song or a patriotic song yet unique quality of the composer Bishnu Prasad Rabha was always there. He was born to Sardar Bahadur Gopal Chandra Rabha, an efficient officer under the Governor of Bengal. He was honoured with Order of Merit of the British empire. Bishnu Prasad’s mother was Gethi Rabha. He was born as the eighth child on 31st January, 1909 at Dhaka. Gopal Chandra Rabha was a great lover of music. Music sessions were held at his residence where the little Bishnu Prasad got acquainted with all the stalwarts of music in Bengal. Unfortunately, his father Gopal Chandra met an untimely death and the family fell into adversity. His widow Gethi along with her children took shelter at their own house in Tezpur. Bishnu Prasad resumed his studies in Tezpur He continued with his other co-curricular activities as well.

It is no easy task to assess the worth of the multi -talented personality of Bishnu Prasad Rabha. In his lifetime he was a live legend. Music, fine arts, theatre performance, creative writing, politics, creating social awareness- he explored in all these diverse fields and won accolades for his exceptional contribution. His physical contribution towards the greater Assamese society came to a stop on 20th June, 1969 due to throat cancer. But the grand legacy of his craftsmanship lives on. In this Paper an attempt has been made to assess the socio-cultural elements present in his songs.

Published: January 2024

Physical education is seen as an essential subject for the development of healthy habits and well-being, in line with Sustainable Development Goal. Furthermore, the impact of technology on all aspects of life is now an undeniable reality. The field of education is no exception, and digitalisation has undoubtedly been accelerated by the emergency situation resulting from the COVID-19 pandemic. This paper aims to analyse the scientific production related to the field of physical education, technology, and the pandemic from a double perspective. A bibliometric approach was used to identify the variables of impact, collaboration, production, and dissemination. While the content analysis allowed us to delve deeper into the topics most frequently chosen by researchers, we found that the articles focused both on the circumstances experienced by practising teachers and on the adaptations made in the teaching/learning process with trainee teachers and students at different stages of education. Thus, technology has emerged as a fundamental tool in physical education during the pandemic, making it possible to develop or maintain better health and learning.

Association of Wilms Tumor with Crossed Fused Renal Ectopia in Children: A Case Report
Authors: Ali Sajid , Latif Tariq , Sheikh Muhammad , Shafiq Muhammad
Published: January 2024

Introduction: Wilms tumor is the most common renal malignancy in children. The occurrence of Wilms tumor with various congenital genitourinary anomalies has been reported, particularly in horseshoe kidneys, hypospadias, disorder of sexual development, and double collecting system. However, Wilms tumor with crossed renal ectopia is a rare finding.

Case Description: We are reporting a case report of Wilms tumor in a 3-year-old girl who presented with a huge left flank mass with cross-fused renal ectopia. After the initial workup and triphasic computed tomography (CT) scan of the chest, abdomen, and pelvis for confirmation of diagnosis and metastasis, the patient underwent image-guided tissue biopsy followed by neo-adjuvant chemotherapy, left radical nephrectomy with separation of fused right ectopic renal moiety and adjuvant chemoradiation.

Practical Implication: This report shows an association of Wilms tumor with cross-fused renal ectopia, a rare combination. Unusual findings on imaging with unilateral flank mass should be considered as part of the differential diagnosis for this rare finding. Adjuvant chemotherapy and modern imaging helped delineate the anatomy and ease the surgery for safe resection, improving the overall outcome.

Published: January 2024

Introduction: Renal artery embolization has been used in a palliative fashion for symptomatic relief of hematuria or flank pain in unresectable renal cell carcinoma in adults. There is limited data on using embolization for actively bleeding and unresectable tumours in the oncological pediatric population. Case description: A previously healthy, five-year-old boy with no significant past medical or surgical history presented to the clinic with gradually worsening abdominal distension associated with occasional abdominal pain, gross hematuria, and lethargy for four months. Diagnostic investigations showed an 18 cm left-sided metastatic (pulmonary) renal tumour (Wilms), which was deemed unresectable on imaging. Treatment was planned on SIOP-RTSG protocol. However, he became hemodynamically and vitally unstable with acute sudden distension of the abdomen on the left side after the first cycle of chemotherapy. Imaging showed active bleeding from an inferior branch of the left renal artery. Selective angioembolization was done, and chemotherapy was reinitiated with a patent left main renal artery. Following the fourth cycle of chemotherapy, he developed hemodynamic instability and abdominal pain; imaging revealed the resolution of pulmonary nodules and bleeding from the left renal artery (main); this was again embolized, and the patient was stabilized. The patient was operated on after optimization and complete resection of the mass was done with negative margins. On six months follow up, he is well. Practical implications: To the best of our knowledge, this is the first case where angioembolization has been done in conjunction with neoadjuvant chemotherapy to downsize a Wilms Tumor to achieve favourable outcomes. Continued research efforts are necessary to optimize strategies and improve the prognosis for pediatric patients, and this case is one of the prime examples.

In general, this report bears on the total forest area in Denmark, irrespective of ownership category and holding size. The reason is that from most points of perspective, almost all Danish forest holdings have the characteristics of small-scale forestry. Furthermore, the entire population is considered to be urban as only a small percentage is dependent on rural-type income. By far the most important limiting factor on forest entrepreneurship in Denmark is the ownership structure in combination with the wealth of the country. There area a large and increasing number of forest holdings in the smaller size classes, where forestry as a business and livelihood is not a primary aim. Recent decreases in the prices of traditional products and hence decreases in economic performance of the primary forestry sector represent an additional limiting factor. This development has made private forestry – but also public forestry to some extent – look for opportunities for increasing income generation from non-wood products and services. A few forest owners have demonstrated great inventiveness and creativity – proving that many services can become income generating. Society has developed some tools to remedy the potential welfare implications and support and improve the technological innovation and management processes of the sector in general. The key question and issue that research must study and private initiative deal with is how to build and develop markets for ever-increasing ‘softer’ goods and services from the forests at large.

In Lithuania forests occupy about 2 million hectares, it consists 31.3% of total land area. 32.2% of forests are privately owned. Annual removal is 6.5 million m³. The main production of the Lithuanian woodworking industry is sawn wood, furniture. Lithuanian forests are not only the source of wood products but also non- wood forest products such as berries, mushrooms, game etc. Forests are owned by 222.2 thousands private forest owners and 42 state forest enterprises. Forest industry consists 873 companies; most of there are SME’s. The main factors effecting the competitiveness of forest-wood /non-wood/servicesconsumer chain from the point of view of entrepreneurship in Lithuania: rich wood and non-wood products resources; low level of round wood prices;, favourable geographical location; low cost of labour; the possibilities to get financial support from EU funds. Barriers to entrepreneurship: low level of domestic market development for wood and non-wood products (especially for small-sized round wood); the small-scale private forestry; high transaction cost for entrepreneurship; low capital resources (GDP per capita is low; biggest part of consumption expenditures fall to food and housing); low level of investments and innovations; very weak integration of forest sector to rural development programmes; low knowledge of business establishment and management; weak connections between research and business. The main problems and research questions for enterprise development in the forest sector: domestic market development strategies; urban consumers demand for forest products and services, integration of forestry into rural development; clasterisation of wood working industry; social structure of small-scale private forest owners; conflicts resolutions of multipurpose forest utilisation.

Competitiveness of Romanian wood processing industry/NWFP on external markets is based mainly on the comparative advantage of lower labour costs. Competitiveness was affected till recently by the regulation of timber prices, restriction on timber trade and monopolistic position of the national forest administration. In the last decade the low level of internal consumption of forest products and the system of selling timber from public estate (NFA and the communal forests) had a high impact on firm development, particularly for firms from harvesting and primary wood processing. Before the years 2000 - 2001, the development of the SMEs and of the associations of the private owners faced difficulties because of lack of public programmes addressing them. Financial system started only recently to have special programmes and/or credit lines for SMEs.

Although there is a very wide size range of private forest/woodland units in the UK, the majority of non-industrial private forest (woodland) holdings are small. The objectives of many owners are more orientated towards amenity than commercial forestry. The low profitability of private forestry is compounded by relatively high wage rates and other production costs and low timber prices. In the UK there is a weakly developed wood culture. Other materials dominate construction and wood products are not seen as high performance materials. The wood product market is dominated by imports and there is a lack of skilled workers and designers in the UK. While there has been a growth of demand for many NTFPs, the same pattern of import dominance prevails. Even where market opportunities exist, firms are likely to remain small. In the UK labour costs are quite high and there may be labour shortages in areas with high levels of NTFP. There can be logistical problems with trying to aggregate supplies from small fragmented forests. In some non timber forest services, such as active recreation, the UK may be advantaged by a large and dense population, but the state forest sector, rather than private woodland owners may be in a better position to provide such facilities, although nearby related private service providers may benefit.

The rising discrepancy between increased demand of forestry products and their shrinking supply due to the restricted wood reserves is a common tendency for most of the industrialised and under industrialised economies. There are many reasons for it, which in most of the cases are rather individual for every country. The analysis of these reasons reveals important features for every country and the comparative analysis of these reasons allows drawing conclusions of utmost theoretical and practical significance.

Poprzez ogólne zdefiniowanie bezpieczeństwa starano się ukazać kwestię wielowymiarowości zadań polskiej Policji wodnej. Celem artykułu w związku z przedstawionymi założeniami, jest wskazanie sposobu zarządza bezpieczeństwem Policji wodnej nad wodą na przykładzie funkcjonowania Komendy Miejskiej Policji w Kaliszu. Kształtowanie, a zarazem utrzymywanie przez władze państwowe właściwego stanu bezpieczeństwa, zobowiązuje do postawienia w stan najwyższej efektywności zaangażowanych organów. Policja wodna, będąca jednym z filarów służb mundurowych, stanowi kluczową rolę w zapewnieniu bezpieczeństwa na obszarach wodnych. W artykule opisano zadania oraz wyzwania, z którymi Policja wodna spotyka się w codziennej służbie, a dokładniej: nadzór nad żeglugą – za sprawą kontroli i regulacji ruchu jednostek pływających na rzekach, jeziorach i morzach, zwalczanie przestępczości morskiej – przemyt i kradzieże, co wymaga skoordynowanych działań z innymi służbami, także na poziomie międzynarodowym, specjalistyczne umiejętności i wyzwania – umiejętność pływania, znajomość prawa, obsługa sprzętu oraz prowadzenie działań ratowniczych często w niesprzyjających warunkach atmosferycznych. Skuteczność zadań wykonywanych przez Polską Policję wodną uzależniona jest od prawidłowo działającego systemu doboru kandydatów do służby wraz z ich specjalistycznym przeszkoleniem zawodowym. W artykule zostały przedstawione najistotniejsze kwestie organizacyjne dotyczące tej formy służby policyjnej, obsady – kadry, zadań, sprzętu i regulacji prawnych. Podkreślono również, że praca w policji wodnej jest wymagająca i wiąże się z ryzykiem zawodowym, na co wpływają nielegalne połowy czy katastrofy morskie. Istotnym są także zmiany klimatyczne, które wpływają na warunki pogodowe na wodach, czego konsekwencją może być zwiększone ryzyko powstawania incydentów morskich. To sprawia, iż funkcjonariusze powinni wyróżniać się ogromną elastycznością i gotowością na szybkie reagowania w różnorodnych sytuacjach. Zatem zasadniczy problem badawczy brzmi: jakie metody zarządzania bezpieczeństwem wykorzystują funkcjonariusze Policji wodnej na przykładzie Komendy Miejskiej w Kaliszu?

Authors: Tsytsiura Yaroslav , Tomchuk Oleksandr
Published: January 2024

The article is devoted to the study of the role of micronutrients in their application in the form of foliar fertilization in view of their influence on the quality indicators of the formed crop, in particular on the oil content of seeds as a basic indicator that determines the value of winter rape as a crop for multipurpose use. The effectiveness of monocomponent application of the main physiologically active microelements in two phenological critical phases of growth and flowering of winter rape plants with different dominance of growth and growth-reproductive processes of plant organism differentiation - in the phenological phases of stemming and flowering - was investigated. The effectiveness of the influence of single-component microelements selected by the typological composition of modern multicomponent chelated microfertilizers in the form of sulfate salts, boric acid and ammonium sulfate at a physiological concentration of 0.2 %, taking into account the regulation of concentrations of physiologically active agrochemicals in the format of foliar feeding with aqueous salt solutions, was determined. It was found that the use of each of the studied microelements was effective and significant in terms of increasing the oil content of seeds in comparison with the control variant of water treatment. Individual peculiarities of seed oil content formation for two high-intensity varieties of winter rape for each of the studied microelements were established both from the standpoint of the increase in oil content to the control and from the standpoint of assessing the variability of its value, taking into account the two-year cycle of study and variation within the general set of the obtained accounting values within the replications of the experiment. On the basis of the data obtained, the expediency of the timing of foliar fertilization with microfertilizers of winter rape hybrids was determined and the role of the genotypic component in the effectiveness of the use of corrective foliar fertilization with various microelements was noted. It was established on the basis of a two-year research cycle for a guaranteed increase of oil content in seeds of intensive winter rape hybrids by at least 0.6-1, 8 % under the condition of one-component use of trace elements in the form of foliar feeding, they should be used in the following order of increasing expediency and validity of Co>Zn>B>Cu>Mn>Mo in the form of a solution of salt sulfates, boric acid and ammonium molybdate at 0.2 % concentration of the working solution for foliar feeding. Prospects for further research in the field of optimization of fertilization of intensive hybrids of winter rape with microfertilizers are formulated.

Published: January 2024

According to the research results, it was found that rooting and further development of rooted green viburnum cuttings of the usual variety depends on the area of the leaf blade. Analyzing the influence of the size of the leaf surface on the rooting of cuttings of the Velikoplidna variety in the studied period of cuttings, it should be noted the high rooting of cuttings in the variant without shortening of the leaf surface. A gradual decrease in the area of the leaf plate led to a significant decrease in the rooting of green cuttings. Green cuttings of the Velikoplidna variety harvested during the period of mass flowering from the basal part of the shoot with whole leaf plates were characterized by significantly higher rooting, number and length of the root system compared to cuttings harvested from the medial and apical parts.Green cuttings of the Velikoplidna variety harvested during the period of intensive growth of shoots from the medial part of the shoot with whole leaf plates were characterized by significantly higher rooting, number and length of the root system compared to cuttings harvested from the basal and apical parts. Green cuttings of the Velikoplidna variety harvested during the period of slow growth of shoots from the apical part of the shoot with whole leaf plates were characterized by significantly higher rooting, number and length of the root system compared to cuttings harvested from the basal and medial parts. Rooting and subsequent growth and development of rooted viburnum cuttings of the ordinary Velikoplidna variety depends on the area of the leaf surface. A decrease in the area of the leaf plate leads to a significant decrease in rooting and negatively affects the development of the adventitious root system. The best indicators are characterized by green cuttings from the basal part, harvested during the period of mass flowering, during the period of intensive growth of shoots, cuttings harvested from the medial part of the shoot, during the period of slow growth of shoots - from the apical part of the shoot.
VEGETATION PERIOD OF SOY VARIETIES OF DIFFERENT MATURITY GROUPS DEPENDING ON INOCULATION AND EXTRA-ROOT NUTRIENTS UNDER CLIMATE CHANGE
Authors: Korobko Alina
Published: January 2024

The article presents the results of studies of the influence of inoculation and foliar fertilization with multicomponent chelated microfertilizers on plant height, leaf surface area, and duration of interphase periods of mid-early and mid-ripe soybean varieties. We used biological preparations that do not harm the environment and meet all environmental standards. The medium-early variety of the Canadian selection Amadeus and the medium-ripening variety of the Ukrainian selection Samorodok were studied. It has been established that inoculation of seeds with bio-inoculants «Rizolain+Rhizosave», as well as foliar feeding with chelated microfertilizers in a complex with trace elements (bioactivator «Azotophyt-r» and growth stimulator «Organic-balance» in a complex with trace elements «HelpRost soybean» and «HelpRost boron» contributes to an increase in the leaf surface area by 3.2 thousand m2/ha in the Samorodok variety compared to the control. A slightly higher indicator was noted in the Amadeus variety, the leaf surface area in the same variants of the experiment increased by 3.4 thousand m2/ha compared to with control. In the soil and climatic conditions of 2022, a complex combination of pre-sowing seed treatment and foliar fertilization led to an increase in the height of plants of the investigated varieties by 10-23% compared to the control (from 1 cm in the phase of 2-3 true leaves to 14 cm in the phase of full maturity) . The increase in plant height of the investigated soybean varieties was associated with the extension of subsequent phenological phases of growth and development in connection with inoculation and foliar feeding. The use of high-quality inoculants with a high content of nitrogen-fixing bacteria for the treatment of leguminous seeds and biological preparations for feeding is now a necessity, as it allows to fully realize the genetic potential of modern varieties, and therefore to ensure the highest yields, which is especially important for organic cultivation. Obtaining a high-quality soybean crop with high profitability can be ensured due to the rational use of inoculants that have a positive effect on the accumulation of nitrogen in the soil. In this way, soybean plants are supplied with nitrogen and conditions are created for the accumulation of nitrogen for subsequent crops in the crop rotation.

Authors: Okrushko Svitlana
Published: January 2024

The article summarizes the research results on crops and weeds interaction, and the herbicide effect on weediness and their harmfulness in agrophytocenoses of winter wheat. A group of dicotyledonous weed species (89%) prevailed in the crops. Eliminating the competitive strain between plants by using the herbicide Ellay Super has had a positive impact on winter wheat vegetation. All experimental varieties responded by increasing both the total number of stems and the number of productive stems. A greater number of stems were formed in the areas where the herbicide was applied in autumn than when it was applied in spring for 2 experimental years. The share of productive stems from the total number ranged from 88.6% to 90.4%. There is a sharp decrease weediness level after the third stage of the crop’s cultivation (stem emergence) because the above-ground winter wheat shades and suppresses segetal vegetation. All experimental wheat varieties demonstrated a highly competitive ability to weeds, i.e., the index was above 80%. The mass of segetal vegetation was insignificant, i.e., 19-24 g/m2. However, their mass was 105-148 g/m2 on areas without crops. The lowest weed pressure index was in the Shestopalivka variety (80.4%), and the highest one was observed in the Legenda Bilotserkivska variety (83.8%) for two experimental years. Autumn application of Ellay Super herbicide provided better starting conditions for growth and development for all experimental varieties of winter wheat than spring application. It also allowed cultivated plants to realize their genetic potential and form a high yield level. The increase in grain yield was from 0.7 t/ha in the Karmeliuk variety to 0.73 t/ha in the Legenda Bilotserkivska variety. The highest yields (5.92 t/ha and 5.67 t/ha) were obtained on the plots of winter wheat of the Legenda Bilotserkivska variety.

At the end of the 20th century, the constant growth of the population and the rapid development of production brought the situation with the state of the environment in many countries and regions of the world to the brink of an ecological crisis. One of the main factors in the degradation of the natural environment is its pollution by various pollutants, among which one of the main places is occupied by heavy metals. Given the above, it becomes clear the relevance of research on the impact of heavy metals on plants. Currently, they are actively held in many countries of the world. The article is aimed at studying the influence of heavy metals on the main physiological processes that occur in plants. The results of studies on the influence of heavy metals on the main physiological processes of grain and leguminous crops are presented. Based on the results of the analysis, it was proven that accumulating in large quantities in plants, heavy metals cause a negative impact on growth, development and other physiological processes. It was established that in the presence of large concentrations of these elements in cereal plants, a decrease in the height of the stem, a decrease in the number of internodes, a decrease in the accumulation of raw and dry biomass, as well as a decrease in the size of inflorescences are observed. The main reasons for the decrease in above-ground biomass productivity in plants are the negative impact of heavy metals on the growth and development of plants and the intensity of photosynthesis. Individual types of plant groups show different ability to accumulate heavy metals. The results of our own research established that in the presence of high concentrations of heavy metals, a decrease in the linear dimensions of leaves was observed in almost all types of plants with which research was conducted. All of the above testifies to various aspects of the effect of heavy metals on metabolic processes and the viability of plants. They affect various functional groups of biologically important substances of the body, displace essential metals from metal-containing complexes, and also generate active forms of oxygen, which often leads to the occurrence of an oxidative explosion in cells and even the death of plants.

Growing corn is a complex process, the success of which depends on compliance with the cultivation technology. Increasing the productivity of modern maize hybrids without incurring high cultivation costs is possible primarily by optimizing the plant nutrition area by using different row spacing. The research on this topic was conducted during 2021-2022 in the conditions of Organic-D LLC in the village of Sutisky. We have found that row spacing significantly affects the complex of economically valuable traits and productivity of corn plants. Reducing the row spacing from 70 to 45 cm, especially for mid-early and mid-season maize hybrids, increases the competition of plants for light and promotes plant elongation and linear growth by 2-5 cm. Increasing the row spacing from 45 to 70 cm has a positive effect on increasing the length and weight of cobs in the group of medium-early and medium-ripening maize hybrids, causing an increase in the number of rows of grains by 1.2-1.3 pcs. For the group of early maturing hybrids, the change in row spacing did not have a significant effect on cob length and cob weight. The largest number of cobs at a row spacing of 45 cm was formed by early ripe corn hybrids Dniprovskyi 181 SV - 76.3 thousand pieces per hectare and DMS Coral - 75.8 thousand pieces per hectare. The use of row spacing of 70 cm for the mid-early and mid-season group contributes to the formation of the largest number of cobs for the mid-season hybrid - Vizir - 84.1 thousand units per hectare and the mid-early Bogatyr - 81.8 thousand units per hectare. Extending the duration of the growing season in the studied maize hybrids requires the use of row spacing of 70 cm, while the number of grains in a number of medium-early and medium-ripening hybrids increases by 4.2-9.5 pcs. The increase in yield due to the use of row spacing of 70 cm was significant for mid-early and mid-season hybrids and amounted to 0.36-2.07 t/ha, compared to the row spacing of 45 cm.

The process of photosynthesis and the intensity of its work are the basis of the formation of productivity and the level of productivity of agrophytocenoses of agricultural crops, including soybeans. One of the main tasks of modern intensive cultivation technologies is the creation of optimal conditions for the development of the assimilation surface, its long-term operation and the maximum accumulation of organic matter by plants. This scientific article presents the results of field research on the impact of biological preparations of different mechanisms of action created on the basis of phosphorus and potassium mobilizing and mycorrhizal forming bacteria on the photosynthetic productivity of soybean crops at different levels of mineral fertilization, namely on the dynamics of the leaf surface area, the formation of the photosynthetic potential of crops and net productivity of photosynthesis. Field research was conducted on gray forest medium-loamy soils at the experimental field of the Agronomic Research Field of VNAU during 2017-2021. According to the results of the research and the processing of the obtained data, it was established that the use of Groundfix soil biofertilizer at the rate of 5 l/ha during the pre-sowing cultivation period and the pre-sowing treatment of seeds with the biological preparation Micofrend at the rate of 1,5 l/t against the background of complete mineral fertilization ensured the formation of the maximum in the experiment the area of the assimilation surface was 40,4 thousand m2/ha, which exceeded the control by 11,6 thousand m2/ha. In addition, based on the calculations, it was found that this version of fertilizer provided the formation of the highest photosynthetic potential in the experiment at the level of 3,153 million m2 days/ha, and the net productivity of photosynthesis, which, depending on the interphase period, was 5,44, 2,16, 1,76, 2,53 and 1,34 g/m2 per day. The article also provides the results of correlation calculations of the closeness of the connection between the area of the leaf surface, the amount of accumulated dry matter and the level of productivity.
BIOLOGICAL NITROGEN FIXATION AS A WAY OF INCREASE YIELD OF SOY

The article highlights the importance of soybeans as one of the main agricultural crops for the life support of society with food. It is well known that soybeans have been the main high-margin crop for many global farmers, including Ukraine, in recent years. The interest in this crop continues to grow as new opportunities for its sale abroad open up, especially in such a giant country as China, the world's largest soybean importer. The right variety accounts for more than 50% of production success. It is important to identify and create optimal conditions for realising the potential nitrogen-fixing activity of soybeans of each variety in specific soil and climatic conditions. Scientists have pointed out that the main reasons that significantly limit symbiotic fixation in our conditions are relatively drier soybean cultivation conditions, especially in the face of abrupt climate change. However, it is also noted that the starting rates of nitrogen fertilisers + symbiotically fixed nitrogen can only offset part of the soybean plants' need for a yield of 4.0 t/ha. The air contains about 76% of nitrogen in the form of N2 gas, which is not available for plant nutrition. However, thanks to the unique ability of legumes to form symbiotic relationships with bacteria of the Bradyrhizobium and Rhizobium genera, N2 gas is converted into an ammonium form of nitrogen suitable for plant use. This interaction takes place in the nodules, which contain the respective bacteria. According to established data, up to 70% of the total nitrogen consumption of soybeans is obtained through biological fixation of nitrogen from the air through symbiosis with nodule bacteria. Based on the analysis of scientific publications on the symbiotic productivity of soybean crops in Ukraine and the world, the indicators of biological fixation by soybean crops in the context of the main soybean producing countries are presented and the importance of soybean cultivation in Ukraine is proved. It is confirmed that soybeans are an important strategic crop in Ukraine, which contributes to the stabilisation of agriculture, increase of soil fertility and nitrogen reserves, eliminates protein deficiency and helps to solve the food problem. The increase in gross soybean harvest is not only due to the expansion of sown areas, but also due to higher yields. To increase the efficiency of soybean production, it is proposed to introduce a set of innovative solutions at different stages of production, as well as to use new, productive varieties. In many publications, the authors emphasise that 30-35% of success in soybean cultivation depends on the right choice of variety and optimally selected technological methods of growing this crop.
