Study of the impact of traditional and zero-tillage systems and organo-mineral fertilization systems with the use of green manure crops in intermediate post-harvest sowings on crop weediness and soybean yield when growing it in an irrigated short-rotation crop rotation of the Southern Steppe of Ukraine. The research was carried out on the basis of a stationary experiment laid out in the fields of the Askanian State Agricultural Research Station Institute of Irrigated Agriculture of NAAS in the area of operation of the Kakhovka irrigation system. The scheme of the experiment included three variants of the main tillage and four variants of fertilization with post-harvest sowings of green manure of buckwheat (Fagopyrum esculentum Moench.), phacelia (Pracelia tanacetifolia Benth.) and white one-year-old sweet clover (Melilotus albus). Field, quantitative-weight, calculation-comparative, and mathematical-statistical methods were used. The average number of weeds in soybean crops when plowing was the lowest and was 28.5 pcs/m2. With zero tillage, both in the second year and longterm use, an increase in the weediness of crops was observed by 16 and 8.5 pcs/m2 , respectively. When sowing soybeans according to zero technology, weediness was lower in the options with post-harvest sideral sowing of phacelia and buckwheat, where the number of weeds, compared to the control, was 10 and 16 pcs/m2 fewer. For all methods of the main tillage, an increase in soybean yield was recorded when using post-harvest green manures, which was 0.22–0.57 t/ha when sowing buckwheat on green manure, 0.06–0.23 t/ha when using white one-year-old sweet clover, and 0.29–0.67 t/ha when using phacelia. It was established that when growing soybeans in an irrigated short-rotation crop rotation in the Southern Steppe zone of Ukraine, the least weediness of crops and the highest crop yield at the level of 3.77 t/ha was provided by plowing to a depth of 28–30 cm. Sowing of post-harvest green manures contributed to an increase in soybean productivity from 0.06 to 0.67 t/ha. When growing soybeans according to zero technology, using buckwheat in the intermediate post-harvest sowings and phacelia for green manure can reduce weediness of the main crop by 24 and 39%, respectively, and increase productivity by 0.22 and 0.29 t/ha.

The main indicators of soil fertility based on the results of an agrochemical survey of agricultural lands in Chernivtsi region in the XI round (2016–2020) are given. It was established that the acidity of the soil solution in the region is dominated by lands close to neutral (31.8%) and neutral (36.5%). The weighted average indicator of saline pH is 5.8, which corresponds to a close to neutral reaction of the soil solution. According to the level of humus provision, soils with an average humus content prevail (66.7%), and the weighted average humus content in the region is 2.7%. According to the content of easily hydrolysable nitrogen, most of the lands have very low (48.3%) and low nitrogen content (48.7%). The weighted average indicator of easily hydrolysable nitrogen content for the reporting period is 106.4 mg/kg of soil, which corresponds to the low availability of this element. The region is dominated by lands with an average content of mobile phosphorus compounds (31.5%) and the average weighted indicator of the content of mobile phosphorus compounds is 56 mg/kg, which corresponds to average availability. In terms of the content of mobile compounds of potassium, lands with a very high content of potassium prevail (51.5%), although the weighted average indicator of the content of mobile compounds of potassium is 78 mg/kg, which corresponds to the average supply of the macroelement. It was established that in the Chernivtsi region the largest area is occupied by soils of average quality (68.5%), and the weighted average assessment of agricultural land in the Chernivtsi region is 51. A comparison of the quality assessment of the soils of the Chernivtsi region for the 10th (2011–2015) and 11th rounds (2016–2020) of agrochemical surveys was made. The results showed that the quality of the soils in the Kelmentsi and Kitsman districts has hardly changed. The soil quality assessment of Novoselytskyi, Hertsaivskyi, Vyzhnytskyi and Hlybotskyi districts improved by 3–6 points. The qualitative assessment of the condition of the lands of Khotynskyi (+8 points), Storozhynetskyi (+13 points) and Sokyryanskyi (+19 points) districts improved significantly. A decrease in land quality indicators was recorded in Zastavnivskyi (–3 points) and Putilskyi (–4 points) districts.

To ensure the maximum protection of agricultural crops from climatic factors unfavorable for their growth and development, it is necessary to create an optimal number of field protection forest strips. In particular, for the Forest-Steppe zone of Ukraine, less than half of the optimal needs are available, which indicates an urgent need for their additional creation. The expediency of creating fast-growing and multifunctional field forest strips is substantiated, and the productivity of new bioenergy crops during their formation for use in beekeeping and as biofuel is determined. For this purpose, a model of the artificial formation of a forest strip with its possible further exploitation is proposed. The most optimal one is to develop the concept of creating field forest strips with the use of multifunctional tree species, which, in addition to the function of wind, water and dust retention, will also perform other economic tasks. In particular, along with their intended purpose, they can be used as raw materials for biofuel production and as early honey plants. For the accelerated creation of field protection forest strips, it is advisable to use mixed 6–8- row plantings, where the middle 2–3 rows are planted with the involvement of tree species, including the use of species valuable as raw materials for beekeeping. These forest strips are complemented on both sides by planted strips of energy crops, which are important for beekeeping and are a valuable resource for obtaining fuel raw materials. For this purpose, it is advisable to plant 10–12 thousand pieces on one hectare poplar cuttings (Populus sp.), 1250 pieces of paulownia plants (Paulownia tomentosa Steud.) with a row width of 2×4 m and 17–18 thousand pieces cuttings of energy willow (Salix viminalis L.). It is also possible to replace part of the poplar cuttings with cuttings of common robinia (Robinia pseudoacacia L.) and linden (Tilia cordata Mill.). The creation of such plantations near settlements will contribute to their significant use of raw materials and will be quite effective in carrying out their main function of ecological stabilization of agro-landscapes.

The study deals with the evaluation of drinking water quality in rural settlements of Hoshcha (Rivne) district of Rivne region. It has been analyzed the concentration of biogenic (copper, zinc) and nonbiogenic (plumbum, cadmium) heavy metals in the water of the wells in the villages of Sadove, Zhalianka, Yuchyn and Tuchyn and artesian wells in the village of Tuchyn during 2012–2018. The research has given fundamental sources of underground waters pollution with heavy metals. It has been revealed that in the water of the wells Cu and Zn concentration does not increase maximum permissible concentrations during the whole period of research. The study demonstrates that water quality of the wells springs is not appropriate to the standard indicators according to the plumbum and cadmium. The authors point out the increasing of maximum permissible Pb concentrations in the wells of the villages of Sadove by 1.02–1.37 times (2012–2014, 2016, 2018) and the village of Tuchyn by 1.17–2.07 times (2012–2018). It has been stated that Cd concentration increases maximum permissible concentration in the wells of the villages of Sadove (by 1.6–3.8 times), Zhalianka (by 1.8–2.5 times), Yuchyn (by 1.3–2.7 times) and Tuchyn (by 1.8–4.5 times). Under the conditions of optimal concentrations biogenic heavy metals are necessary to provide life activities and functions of physiological processes of all organisms. However, continuous consuming of drinking water that is polluted with heavy metals negatively impacts on the organism and may cause acute and chronic diseases. Their impact depends on the concentration of the element, characteristics and intensity of its getting, absorption speed, retention and removal speed, and also human’s general state of health. In the village of Tuchyn according to cuprum, zinc, plumbum and cadmium concentration the water of artesian wells is appropriate to the permissible standards during 2012–2018 and is suitable for consumption and use. It is obviously that the use of deeper underground water horizons provides the inhabitants of the village of Tuchyn with qualitative drinking water. In the water of settlements wells where the increasing of standard Cd and Pb concentrations was observed it should be developed and implemented effective measures to develop the water quality.

The volume of coarse woody detritus in the 112- year-old hornbeam-maple-ash forest stand of natural origin in «Medobory» Nature Reserve have been studied. The study of dead wood was carried out on a sample plot (0.48 ha) by the method of full accounting. The volume of woody detritus in the forest ecosystem is 62.7 m3∙ha–1and consists of fallen (82.9%) and standing (17.1%) deadwood. The main part of the dead wood volume is formed one tree species — common ash (Fraxinus excelsior L.) (93.0%). In general, woody detritus is characterized by I–IV classes of decomposition, while detritus of decomposition stage I prevails (44.2%), shares of other stages are slightly smaller: II (30.9%), III (23.6%) and share of stage IV is insignificant (1.3%). No coarse detritus of the last (V) decomposition stage was found on studied plot. The volume of standing dead wood is 10.7 m3∙ha–1 and is formed by broken dead trees. In terms of tree species composition, common ash dominates (94.4%), and the share of hornbeam (Carpinus betulus L.) is insignificant (5.6%). In the total standing dead wood volume, wood of decomposition stage I predominates (9.4 m3∙ha–1, 87.9%), compared with stage II (1.3 m3∙ha–1, 12.1%). Volume of fallen dead wood is 52.0 m3∙ha–1 and is formed by whole fallen trees, fragments of fallen trees (trunks) and rough branches. In terms of species composition, woody detritus of common ash predominates (48.2 m3∙ha–1, 92.7%), and the proportions of other species are insignificant. Fallen dead wood is represented by four stages of decomposition (I–IV). In terms of volume, decomposition stage I (18.3 m3∙ha–1, 35.2%) and stage II (18.1 m3∙ha–1, 34.8%) prevail, detritus of stage III is less (14.8 m3∙ha–1, 28.5%), and the share of stage IV is insignificant. Low volumes of late decomposition stages of woody detritus is explained mainly by influence of forestry activity in the past and relatively short period of strict regime of nature conservation, during which the forest ecosystem developed without human intervention.

The problem of regulation of plant growth and development by physiologically active substances is one of the most pressing problems in modern biology. The widespread use of plant growth regulators (PGR) is an important factor in the effectiveness of crop cultivation technology. A significant achievement is revealing the role of biologically active compounds in the regulation of the most important vital functions of a plant organism, increasing resistance to adverse environmental factors (high and low temperature, drought, soil salinity, diseases, etc.), increasing the yield and quality of agricultural products. Plant growth stimulants are biologically active substances of natural origin that enhance the intensity of metabolic and growth processes in plants and increase crop productivity. A range of scientists has proved the practical application of Basidiomycota in agriculture, namely in creating biocompositions and preparations based on them to stimulate the growth and development of crop plants and protect them against diseases and pests. In this regard, research in the field of biologically active substances used in the production of tomatoes is a necessary step toward the creation of new technology elements for their cultivation — one of the realistic prospects of realizing this crop’s biological resources and productive resources potential. The study aimed to investigate the impact of biocomposition «Bioekofunhe-1» on tomato growth and development. The biocomposition was created based on Basidiomycota and plant components to stimulate productivity and protect against diseases of agricultural plants. Seeds of three varieties of tomatoes were selected for the experiment: Hibryd Tarasenko 6, Lahidnyi and Prydniprovskyi Rozhevyi. Laboratory tests about matching concentrations of biocomposition and determining their impact on the growth processes of tomatoes were done. We proved that the «Bioekofunhe-1» biocomposition stimulates tomato growth and development. We matched its optimal concentration (0.1%) for effects on the growth processes of seedlings of tomato varieties. The application of the «Bioekofunhe-1» biocomposition in that concentration provides increasing the aerial part length of tomato seedlings of all three varieties.

In this regard, research in the field of biologically active substances used in the production of tomatoes is a necessary step toward the creation of new technology elements for their cultivation — one of the realistic prospects of realizing this crop’s biological resources and productive resources potential. The study aimed to investigate the impact of biocomposition «Bioekofunhe-1» on tomato growth and development. The biocomposition was created based on Basidiomycota and plant components to stimulate productivity and protect against diseases of agricultural plants. Seeds of three varieties of tomatoes were selected for the experiment: Hibryd Tarasenko 6, Lahidnyi and Prydniprovskyi Rozhevyi. Laboratory tests about matching concentrations of biocomposition and determining their impact on the growth processes of tomatoes were done. We proved that the «Bioekofunhe-1» biocomposition stimulates tomato growth and development. We matched its optimal concentration (0.1%) for effects on the growth processes of seedlings of tomato varieties. The application of the «Bioekofunhe-1» biocomposition in that concentration provides increasing the aerial part length of tomato seedlings of all three varieties.","PeriodicalId":7521,"journal":{"name":"Agroecological journal","volume":"6 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78486680","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}

The paper presents three-year field and laboratory research on studying the sunflower hybrids of different cultivation technologies, types of ripeness groups with yield indices depending on using different fertilisers and different types of soil cultivation. The study was conducted when using new hybrids of domestic and foreign selection. The hybrids Grand Admiral and Pegas were selected according to their biological characteristics that are more typical for the zone of Polissia when using standard cultivation technology. It was noted that on sod-podzolic soils with a light mechanical composition, the use of disk tillage tools (BDVP-4.2) to a depth of 10–12 cm was not significantly inferior to the deep loosener (GR-4.5) to a depth of 40–45 cm, which was a shortfall grain yield from disking in both experiments was 0.08 t/ha (37.7%) and 0.21 t/ha (23%). The above-mentioned type of soil is naturally poor in terms of its physical and chemical composition, namely the content of humus (1.0–1.3%), availability of exchangeable potassium and mobile phosphorus (32–52 mg/kg), which creates the need to use scientific approach to the reproduction of soil fertility with the use of organic and mineral fertilizers. It has been proven that when using fertilizers N16P16K16 + N46 (nitroammophosca, 200 kg + urea fertilizer, 75 kg) an increase in sunflower seed yield equals 1.66–1.72 t/hа (281–322%), when using the fertilizers N10P26K26 + N46 (diammophos, 200 kg + urea fertilizer, 75 kg) the increase in yield equals — (287–328%) and when using P5K55 + N46 (phosphorus-potassium fertilizer, 20 kg + urea fertilizer, 75 kg) the increase in yield is the highest and equals 1.85–1.97 t/ha depending on the experiment variant. It is noted that the Pegasus sunflower hybrid was inferior to the Grand Admiral hybrid in all indicators of the experiment, from the form of mineral fertilizers to soil cultivation, and is: when applying N16P16K16 + N46 — 0.66 t/ha; N10P26K26 + N46 — 0.39 t/ha; P5K55 + N46 — 0.38 t/ha.

The number of colony-forming units (CFU) of micromycetes in soybean seeds of Suzirya and Kent varieties, created by Filazonite technology, was determined. A significant suppression of micromycetes was found in soybean seeds of Suzirya and Kent varieties compared to the control sample. It was established that the formation of CFU micromycetes on soybean seeds of the specified varieties is influenced by seed growing technologies and climatic conditions. Depending on these factors, the number of CFU micromycetes on soybean seeds of different varieties ranged from 0.2·104 CFU/g of seed to 1.5·104 CFU/g of seed, which is almost 2.5 times less than the amount in the control sample (from 0.8·104 CFU/g to 2.7·104 CFU/g of seeds). It was established that the species of phytopathogenic micromycetes belonging to the genera Alternaria, Fusarium, and Penicillium dominate in the soybean seeds of Suzirya and Kent varieties. They are factors of biological pollution of agrophytocenoses and reduction of biosafety of products. The changes in the quality indicators of the researched varieties of soybean seeds, grown under conditions of organic production using biological technologies, were determined. Based on the results of three-year research, it was established that the indicators of the content of protein and oil in the seeds of Kent and Suzirya varieties in all variants were higher than the normative indicators specified in DSTU 4964:2008. TU. SOY. At the same time, the indicator of the mass fraction of seed moisture did not exceed the permissible norms. It was established that the biochemical composition of soybean seeds had a certain influence on the genotypes of the varieties, as well as the types of soil and the climatic conditions of the growing technology. Depending on these factors, the content of protein in the soybean seeds of the studied varieties ranges from 37.5% to 41.11%, fat from 19.02% to 21.7%, and the mass fraction of moisture from 8.8% to 11.4%.

According to V. Vernadskyi, life on Earth has existed forever. The academician paid considerable attention to the study of soils. The latter are able to accumulate and redistribute chemical elements entering the biosphere between landscape elements. Heavy metals (HM) and other priority toxicants from various sources eventually end up in the upper soil horizons, where their subsequent transformation is determined by soil properties. The residence time of heavy metals in the soil is much longer than in other components of the landscape; they are also slowly removed by leaching, absorption by plants and as a result of exogenous processes. Due to the unique role played by chemical elements in the biosphere, their content in the soil is one of the essential and equal ecological factors that determine the development of living organisms in ecosystems. In connection with the rather intensive development of agriculture in the Forest Steppe, special attention was paid to the distribution of Zn2+ and Cu2+ in the soil cover of this zone. The study of the question of the majority of scientists regarding the arrival of chemical elements in the agro-ecosystems of the soil-climatic zones of Ukraine proved that the largest amount of them comes with mineral fertilizers in the foreststeppe zone. Considering the fact that heavy metals are one of the main sources of environmental pollution, particularly in Ukraine, a comprehensive study of their migration halos in the soil is necessary for the development of effective environmental protection measures. Currently, conducting intensive agriculture using modern agricultural technologies is impossible without the use of fertilizers. Fertilizers are the most effective means of increasing soil fertility, productivity, and improving the quality of crop production. However, a significant drawback of many mineral fertilizers is the presence of toxic heavy metals. Yes, some of these elements in small quantities can have a positive effect on the growth and development of plants. The effect of systematic application of fertilizers on the fertility indicators of typical and gray podzolized chernozem, as well as their effect on the content of mobile compounds of elements in soils, was studied. According to the data, with the systematic introduction of increased doses of fertilizers, elements can accumulate in the soil in significant quantities, which negatively affects the properties and fertility of the soil, the harvest and its quality. Heavy metals are among the main toxicants contaminating grain products. As you know, the rates of dispersion and involvement of chemical elements in the biogenic cycle have increased significantly over the past decades, and their extremely high impact on living organisms gives reason to classify them as particularly dangerous pollutants of the biosphere. This is due to the fact that heavy metals are characterized by high toxicity at low effective concentrations, accumulate in individual links of

In order to study invasive species as dangerous elements of foreign flora, modern monitoring studies are needed under the conditions of various ecotopes of a wide range of their transformation. According to the «Strategy of biosecurity and biological protection», alien species are a threat to biodiversity at its various levels. Taking into account that railway tracks are one of the main ways of penetration and initial establishment of synanthropic species in new territories, in 2018–2021, the flora of the tracks in the areas of the Dniester floodplain was studied. 34 invasive species from 14 families were noted, they included Asteraceae (26.47% of species), Brassicaceae and Poaceae (17.65% each), Amaranthaceae (8.82%) and others. The majority of species (55.88%) grows both on track sections and (in addition) next to ruderalized sections of overburden. Another 11 species (32.35%) can be found on tracks, ruderalized areas of overburden and on the roadsides of the nearby highway. Only two species (5.88%) are cultivated. Two more species such as Amaranthus powellii S.Watson, Oxybaphus nyctagineus (Michx.) Sweet are noted only on railway tracks and sections of railway infrastructure. According to the life form, nine species (26.47%) are hemicryptophytes. 23 ones are therophytes (67.65%). Two species are fanerophytes (5.88%). According to the chronotype, 41.18% of the species are aschaeophytes. Kenophytes make 58.82%. Among archaeophytes, most plant species have a frequency of occurrence — «scattered» and «abundant» (35.71% each). Among the kenophyres, there are the most species whose plants were «scattered» (40.00%). In general, the majority of invasive species, by frequency of occurrence, belong to the «scattered» (38.25%) and «abundant» (23.53%) categories. Also there are «single» (17.65%), «usually» (11.77%), «single locality» (8.82%). Most species (70.60%) are represented by wide ranges: cosmopolitan (and hemi-cosmopolitan) make 44.12%, Eurasian form 14.71%, Euro-American make 11.77%. Eight species (23.53%) are particularly dangerous for the environment, as they are transformers of local growth. Most of the plants of invasive species of railway tracks were also found on adjacent ruderalized areas. Therophytes, kenophytes and species with a wide range prevail. They are found, mostly «scattered» and «abundant». Eight species (23.53%) are the most dangerous for environment, because they transform ground place (Ambrosia artemisiifolia, Centaurea diffusa, Conyza canadensis, Grindelia squarrosa, Iva xanthiifolia, Elaeagnus angustifolia, Anisantha tectorum, Setaria glauca).
