Increasingly high requirements for the seed material of medicinal crops are set, which must be harmonized with international standards and requirements. There are guidelines for good cultivation and harvesting practice (GACP) of plant raw materials. The production of medicinal plant raw materials requires not just varietal seeds, but also seed material with high sowing qualities. Therefore, seed quality control is a mandatory measure, which is not possible without established methods for determining its sowing quality. Particular attention in the study of these issues requires the seeds of medicinal plants that are grown for a short time in the culture, which includes St. John’s wort (Hypericum perforatum L.). According to the results of the analysis of scientific literature and normative documents, it is established that in Ukraine for a wide range of medicinal and essential oil crops, including St. John’s wort, there are no regulations (current standards) for methods of determining sowing qualities, technical conditions for seeds. At the same time, the most important indicator of seed sowing qualities is germination. The level of germination is established by the standard ensures normal germination of seeds in the field, the formation of optimal crop density and crop yields. This indicator is basic in the purchase and sale of seeds, the release of seeds for sowing. Therefore, the aim of the work was to develop methodological approaches to determine the germination of St. John’s wort seeds using standard procedures and techniques used in domestic and international practice. The methodological approaches given for other cultures in normative documents both in force in Ukraine and abroad were taken into account. It is established that the methodological features of determining the indicators of germination energy and seed germination of St. John’s wort are the possibility of using filter paper or sand as a substrate for germination. The optimal substrate is filter paper, and the method of germination — on the filter. For seed germination on filter paper and in sand it is recommended to use a constant temperature (+20°C) or variable (+ 20–30°C). Terms of accounting: germination energy — 10, germination — 21 days. Developed methodological approaches to determine the germination of seeds of St. John’s wort are recommended for use in testing laboratories, seed plants and research institutions.

Accumulation of environmentally hazardous agricultural waste, in particular cow manure without the proper treatment, creates an ecological threat to the environment. During the energy crisis, the search for alternative pathways to obtain energy is also one of the most urgent issues today. Cow manure is promising as a substrate for anaerobic fermentation with the production of a valuable energy carrier — methane. Fermentation of cow manure as a sole substrate is not spread. It takes place due to the low efficiency of the process. We hypothesized that low efficiency is caused by the inhibition of the microbiome of cow manure by the end products of fermentation in the gastrointestinal tract of cows and non-optimal conditions for microbial growth. Thus, the goal of the work was to develop the approach of methane fermentation of cow manure using a conversion succession for its effective degradation with the obtaining of a valuable energy carrier. The following methods were used: potentiometric measurement of pH and Eh, chromatographic determination of the composition of the gas phase. To study the patterns of methane fermentation of cow manure, the following treatments were analyzed: 1. fermentation of manure by the autochthonous microtome without regulation of the pH of the medium; 2. fermentation of manure with the addition of fermented sludge of methane tank as an inoculum without pH regulation; 3. via adding fermented sludge of methane tank and with pH regulation. As a result, the fermentation of cow manure by the autochthonous microbiome was shown to be inefficient. In this case, the methane yield was only 20 L/kg of substrate. The inhibition of the microbiome was suggested to take place due to the accumulation of the end products of fermentation. Conversion succession, i.e., the replacement of the autochthonous microbiome, due to the introduction of biomass of fermented sludge of methane tank, provided the increase in the yield of methane to 230 L/kg of substrate. This result testifies the application of another methanogenic microbiome is useful to increase the efficiency of the process. In this case, compounds that inhibited the autochthonous microbiome serve as the substrate for the introduced one. The regulation of the pH allowed creating of the optimal growth conditions for microorganisms and increased the yield of methane to 280 L/kg of substrate. So, the change of the microbiome, i.e. conversion succession, and the regulation the pH made it possible to 14-fold increase in the efficiency of methane fermentation of cow manure. This approach is promising for the effective degradation of cow manure with the production of a valuable energy carrier, methane. The obtained results can be the basis for the further development of environmental and energy microbial biotechnologies.

It is revealed that the fiscal ecological policy plays a principal role in the complex process of economic transformation. One of its functions is a direct participation in the realization of the nature environment conservation policy of European countries, which in turn react resolutely and balanced on the aggravation of resource problems and ecological crisis. The main purpose of this article is the influence identification of the environmental taxation on the realization of the environmental conservation policy of the European Economic Area (EEA) with financial and economic capability of the modern European countries considered. Complex indicators, which are investigated analytically with the comparative analysis considered, are utilized for the realization of the aforementioned endeavor. The experience of the European countries is recommended to be explored, generalized and engrained if possible in Ukraine for modern system of the environmental taxation formation. The indicators, which characterize the level of EU environmental taxation income, are analyzed systematically. As the realization of the fiscal and ecological policy has to become one of the stimulating factors of the environmental conservation, the basic aspects of environmental taxation implementation of the European countries are determined. The systematic approach for environmental taxation influence determination on the successive prospects of environmental conservation doctrine realization by the European community is applied in the article. The European community in turn has to make a balanced choice of the chief priorities for the further community and economic development. It has been proven that the environment degradation and irrational usage of the natural resources are the main motivating stimulus for the environmental conservation policy of Europe transportation. It should be pointed out that the efficacious implementation of the environmental taxation is obligatory for the full-fledged policy realization. The comprehensive investigating method which indicates the real influence of different kinds of the environmental taxation on an increase of the technical level of the production and the auspicious investment climate establishment. The realization of the investment policy of the environmental conservation and fiscal ecological reform are the paramount component of the sustainable development and its fulfillment must be directed to the increase of the quality level of the environment. European countries have already reached certain results, but the modification of nature conservation policy must be continuous and meet the requirements of time. It is investigated that ecotax can play a critical role in material and mental influence on a manufacturer, a consumer and non-ecological services.

The results of the experimental work on the evaluation of the bread-making ability of new varieties of winter triticale of Polissia ecotype, which were carried out in the department of selection and seed production of grain crops of the National Science Center «Institute of Agriculture of the National Academy of Agrarian Sciences», located in Fastiv district of Kyiv region in 2016–2018, are highlighted. The elasticity (P) of the dough on average by varieties was found at the level of 67.2 mm, which corresponds to the indicator of «good filler» wheat, and by varieties ranged from 44 mm (indicator of «weak wheat») in Aristocrat variety to 87 mm («satisfactory improver») in Kotyhoroshko variety. The stretchability (L) of the dough by variety varied from 18 mm (Aristocrat) to 30 mm (Lyubomir) and was 23.5 mm on average. The stretchability of the dough is closely correlated with indicators such as C, the expansion index and the area of the average diagram (r=0.62–0.67). According to the results of calculations, the P/L ratio in winter triticale varieties of Polissia ecotype varied from 1.7 units in Volemir variety to 4.4 units in Kotygoroshko variety, and on average it was found at the level of 2.9 units, winter triticale variety is closer to the optimal value Volemir. According to the flour "strength" alveograph indicator, Solodyuk and Lubomyr winter triticale varieties of Polissia ecotype were distinguished, which reliably prevailed over Poliskyi 7 standard variety (NIR05=17) and amounted to 93 J and 76 J, respectively. The amount of «raw» gluten in winter triticale varieties ranged from 6.4% in Aristokrat variety to 15.0% in KS 9-17 sample, and on average was 11.8%. After drying, the amount of «dry» gluten varied from 2.38% to 5.04%, and averaged 3.9%, which was 33% of the amount of «raw» gluten. The highest indicator of hydration capacity (233.3%) was observed in Petrol variety compared to Polisky 7 standard variety, which significantly exceeded it by 47.6 units (NIR05=14). The physical properties of triticale gluten resemble weak wheat gluten with low elasticity. Tight triticale gluten makes it possible to bake good bread. The volume yield of loaves from triticale flour was 298 ml on average and varied from 260 ml in Polisky 7 variety to 345 ml in Fanat and Solodyuk varieties. Selected winter triticale varieties of Polissia ecotype with satisfactory baking quality, according to the wheat baking technology without adding improvers, are advisable to use in the baking industry.

The taxonomic composition of the collection of subtropical plants of the Khorol Botanical Garden, consisting of 25 species: Asimina triloba (L.) Dunal, Cydonia oblonga Mill., Chaenomeles × californica Clarke ex Weber, Cormus domestica L., Mespilus germanica L., Crataegus azarolus L., Crataegus opaca Hooker & Arn., Prunus dulcis (Mill.) D.A. Webb, Prunus armeniaca L., Hovenia dulcis Thunb., Ziziphus jujuba Mill., Elaeagnus multiflora Thunb., Elaeagnus umbellata Thunb., Maclura tricuspidata (Carrière) Bureau, Ficus carica L., Passiflora incarnata L., Punica granatum L., Feijoa sellowiana O. Berg, Pistacia vera L., Citrus trifoliata L., Diospyros virginiana L., Actinidia chinensis Planch. Plants are presented in the collection areas «Garden of subtropical fruit crops», «Paradise Garden» and «Shaped Fruit Garden». The collection fund of the botanical garden was formed for a long time and each culture is at a certain stage of introduction. Subtropical fruit crops of the Khorol Botanical Garden: Asimina triloba L., Punica granatum L., Zizyphus jujuba Mill., Ficus carica L., Amygdalus communis L., Mespilus germanica L., Diospyros virginiana L. are studied as introductory populations. When creating garden compositions from subtropical species, attention was paid to the reaction of introducers to adverse weather conditions. According to the planting scheme, possible artificial forms of the plant crown are taken into account: formation of a plant with a low trunk and the same rounded crowns, in the form of spherical bushes, with main shoots-conductors formed in the form of ascending spirals. The search for the optimal life form for subtropical fruit introducers in the Forest-Steppe zone of Ukraine is carried out. The problematic moments are revealed and the ways of their solution are offered. During the modification of the crown shape, the morphological structure, peculiarities of growth and development of the introducer in new conditions, resistance to adverse weather conditions were taken into account. Asimina triloba, Cydonia oblonga, Chaenomeles × californica, Cormus domestica, Mespilus germanica, Prunus armeniaca, Ziziphus jujuba, Elaeagnus multiflora, Elaeagnus umbellate, Diospyros virginiana began to bear fruit at 6–9 years of age. The fruits have plants of typical and derived life form. This is the practical purpose of their introduction. Ficus carica, Punica have a modified life form. They are covered for the winter. It is established that most of the species composition of the collection of subtropical plants (22 species) have typical and derived life forms. 7 species: Laurus nobilis, Ficus carica, Camellia sinensis, Passiflora incarnate, Feijoa sellowiana, Punica granatum, Olea europaea in terms of introduction to the Forest-Steppe of Ukraine require mandatory modification of life form.

Berg, Pistacia vera L., Citrus trifoliata L., Diospyros virginiana L., Actinidia chinensis Planch. Plants are presented in the collection areas «Garden of subtropical fruit crops», «Paradise Garden» and «Shaped Fruit Garden». The collection fund of the botanical garden was formed for a long time and each culture is at a certain stage of introduction. Subtropical fruit crops of the Khorol Botanical Garden: Asimina triloba L., Punica granatum L., Zizyphus jujuba Mill., Ficus carica L., Amygdalus communis L., Mespilus germanica L., Diospyros virginiana L. are studied as introductory populations. When creating garden compositions from subtropical species, attention was paid to the reaction of introducers to adverse weather conditions. According to the planting scheme, possible artificial forms of the plant crown are taken into account: formation of a plant with a low trunk and the same rounded crowns, in the form of spherical bushes, with main shoots-conductors formed in the form of ascending spirals. The search for the optimal life form for subtropical fruit introducers in the Forest-Steppe zone of Ukraine is carried out. The problematic moments are revealed and the ways of their solution are offered. During the modification of the crown shape, the morphological structure, peculiarities of growth and development of the introducer in new conditions, resistance to adverse weather conditions were taken into account. Asimina triloba, Cydonia oblonga, Chaenomeles × californica, Cormus domestica, Mespilus germanica, Prunus armeniaca, Ziziphus jujuba, Elaeagnus multiflora, Elaeagnus umbellate, Diospyros virginiana began to bear fruit at 6–9 years of age. The fruits have plants of typical and derived life form. This is the practical purpose of their introduction. Ficus carica, Punica have a modified life form. They are covered for the winter. It is established that most of the species composition of the collection of subtropical plants (22 species) have typical and derived life forms. 7 species: Laurus nobilis, Ficus carica, Camellia sinensis, Passiflora incarnate, Feijoa sellowiana, Punica granatum, Olea europaea in terms of introduction to the Forest-Steppe of Ukraine require mandatory modification of life form. Modification of life form is pruning, as well as warming the crown in the cold season.","PeriodicalId":7521,"journal":{"name":"Agroecological journal","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89982141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ukraine ranks the second (out of 123 countries) in the exports of organic products to the EU according to the study of the organic market in 2019 conducted by the Information Center Green Dossier (OrganicInfo.ua), Organic Standard and the Research Institute of Organic Agriculture (FiBL). The official statistical reviews of IFOAM confirm that in 2018 there were about 510 organic farms in Ukraine, and the total area of the agricultural land on which the organic production is carried out was 429,100 hectares. Among the producers of organic products, more than 4.6% are involved in growing of the legumes. It should be noted that one of the main crops of the Fabaceae family grown in Ukraine is soybean (Glycine max (L.) Merr.). In recent years, there has been a significant increase in sown areas and soybean production, and the issue of its organic production is relevant. The aim of our research was to determine the effect of biological products based on bacteria: Bacillus subtilis, Azotobacter, Enterobacter and Enterococcus, on the main physiological groups of soil microorganisms in the cultivation of soybean plants. The research was conducted at the Institute of Agroecology and Environmental Management of the National Academy of Agrarian Sciences of Ukraine in the Department of Agrobioresources and Ecologically Safe Technologies in the laboratory and vegetative conditions. The soybean seeds of the Suzir’ya cultivar (selected by the National Research Center of the Institute of Agriculture of the NAAS) and Kent cultivar (selected by SAATBAULINZ, Austria) were treated with biological products produced by BTU Center: Phytocide (Bacillus subtilis, cell titer 1–4·109 CFU) cm3), PhytoHelp (B. subtilis — cell titer not less than 4·109 CFU) cm3), MycoHelp (B. subtilis, Azotobacter, Enterobacter and Enterococcus) according to the recommended doses. The methods prescribed in State Standard 7847:2015 was used to determine of the soil microorganisms and their associations. Statistical data processing was performed using the Microsoft Excel software package. The peculiarities of the influence of biological products based on bacteria: Bacillus subtilis, Azotobacter, Enterobacter and Enterococcus on the main physiological groups of soil microorganisms in the cultivation of soybean plants it has been demonstrate. It has been established that in the soybean and Kent soybean agrocenosis, MycoHelp and PhytoHelp biological products effect on the main ecological and trophic groups of soil microbiome, thereby increasing soil microbiological activity; significantly intensify the development of microorganisms that use mainly organic nitrogen compounds (in the system Kent variety — biological product MycoHelp this figure increased in 3.3 times, and at the variety Constellation — biological product PhytoHelp — in 5.3 — 18.8 times compared to the reference and control options, respectively).

Studies have been conducted to establish the influence of plant growth regulators and drip irrigation on the productivity of marshmallow in the first year of the growing season. It was found that the increase in dry grass yield from the use of growth regulators ranged from 0.15 t/ha to 0.88 t/ha without irrigation. In the variants with the use of irrigation, the increase in yield ranged from 0.29 t/ha to 1.16 t/ha. It was found that the yield of dry roots without irrigation with the use of growth regulators increased by 0.05–0.42 t/ha compared to the option without the introduction of growth regulators (control). Under irrigation conditions, the use of growth regulators helped to increase the yield of dried roots of marshmallow by 0.12 0.47 t/ha relative to control. The highest productivity of marshmallow grass was obtained with the application of Emistin and Vimpel, where the yield was 4.69 and 4.88 t/ha without irrigation, in the variants with irrigation the yield was 7.31 and 7.44 t/ha of dry raw materials. The highest yield of dried marshmallow roots without irrigation was in the variants with the application of Vimpel and Potassium Humate where it was 1.89 and 1.95 t/ha. Under irrigation conditions, the highest root yield of 2.22–2.34 t/ha was obtained in the variants with the introduction of Emistin, Potassium Humate and Vimpel. The study of the effect of drip irrigation on the yield of dry raw material of marshmallow showed a positive effect, on average, the increase in yield from the use of irrigation was 2.5 t/ha of grass and 0.39 t/ha of roots. In a study of the influence of growth regulators on the share of leaves in raw materials, it was found that without irrigation among the studied options, the percentage of leaves ranged from 43.5 to 46.7%. The use of Sodium Humate provided the raw material with the largest share of leaves. The smallest share of leaves was under the control and with the introduction of growth regulators of Potassium Humate and Emistin. Under irrigation, the share of leaves in raw materials ranged from 42.9 to 47.1%. The lowest percentage of leaves in the raw material was recorded in the version with the introduction of the growth regulator of Potassium Humate, the highest percentage of leaves was in the version with the introduction of Pennant.

The article reveals the requirements for immediate institutionalization of the current land norms of the Constitution of Ukraine as carried out over thirty years the so-called «land and agrarian reform» in Ukraine does not correspond to the declared land transactions, which aim at the development and real economic and legal strengthening of Ukrainian statehood. The aim of the article is to substantiate the basic principles of emergence of the system of property rights of the Ukrainian people to land and its natural resources in the accomplishment of land reform in New Ukraine as a new paradigm that develops at the highest quantum level understanding of the synergetic role legitimate interests of all citizens of Ukraine. The fundamental differences between the land norms of the Constitution of Ukraine (Articles 13, 14) and the Constitution of the Russian Federation (Articles 9) are revealed. It has been established that in the current hybrid environment of degradation and opposition to the development of the state by the unconstitutional corruption system, there is a need to unblock the resistance — in a constitutional way, by providing an immediate and fair official interpretation of the current constitutional land norms by the Constitutional Court of Ukraine. It was found that due to the absence of a constitutionally declared special Law of Ukraine «On the Right to Use Natural Objects of Property Rights of the Ukrainian People» for a quarter of a century, the rights of their owner (all citizens of Ukraine) are violated and the unauthorized use of the nation’s capital occurs. As a result, the rights, duties and responsibilities of users of natural objects are not standardized, as well as full-fledged requirements for their rational use and protection on a paid basis in accordance with established regulations. The necessity of urgent introduction of land reform to date is proved — in the current constitutional field of Ukraine, ensuring the institutionalization of constitutional norms regarding the land and its natural resources as natural objects of the property rights of the Ukrainian people and the main national wealth, which is under special protection of the state. It is proposed to adopt a number of relevant laws and regulations.
