At present, one of the main tasks is to obtain high-quality and environmentally friendly phyto-products. The interest of consumers in healthy nutrition is increasing every year. Growing plant products using organic technology is becoming widespread. Among a wide range of economic management, organic agricultural production is the only environmentally friendly method on Earth that does not inflict damage on the environment. Organic production systems are based on specific and precise requirements (standards) for the production process aimed at maintaining the optimal state of the ecosystem at the social, environmental and economic levels. The level of plant damage is controlled naturally, as well as with the help of preventive, biological and other modern scientific methods. Organic agricultural production excludes the use of artificial fertilizers and pesticides, as well as genetically modified organisms and products (substances) derived from them. The developed system for the protection of winter spelt against fungal diseases under organic production is based on biological features of mycoses, introduction of varieties with the least degree of affection by pathogens of fungal etiology, application of optimal systems of soil tilling and fertilizing, sowing time and seed application rates, as well as rational use of effective mixtures of biological preparations and plant growth regulators for seed and crop treatment. Organic protection system involves the following: complex treatment of seeds with biological preparation Agat 25-K, PA (0.04 kg/t) and plant growth regulator Biosyl (0.01 l/t) before sowing; spraying of crops at the 31st stage with a mixture of Agat 25-K, PA (0.03 kg/ha) + Biosyl (0.01 l/ha); the same treatment of crops at the 39th stage; spraying of crops with biological preparation Phytodoctor (2.0 l/ha) at the 60th stage. Under organic production, the winter spelt yield preserved due to a set of protective measures amounts to 0.58-0.67 t/ha or 29.6-33.7%. At the same time, the protein content increases by 0.83% and gluten content by 6.9%.

AbstractBrassinosteroids are plant steroidal compounds involved in many functions related with plant development, metabolism, signalling and defense against a wide range of biotic and abiotic stresses. Plant architecture, which has a major effect on crop yield, is strongly influenced by brassinosteroids action. Brassinosteroids are recognized as key regulators of plant growth and development involved in a broad spectrum of processes at the molecular, cellular, and physiological levels. These roles suggest that many of the constraints of present agricultural production might be alleviated by manipulation of genetic determinants dealing with brassinosteroids, as well as by its exogenous application. Brassinosteroids are natural, nontoxic, non-genotoxic, biosafe, and eco-friendly, and can therefore be used in agriculture and horticulture to improve the growth, yields, quality, and tolerance of various plants to biotic and abiotic stresses. The present paper comprehensively reviews the latest results in the field of brassinosteroids and envisages future impacts in agriculture.

In the modern agricultural production, the use of herbicides and other biologically active substances is an important part of the cultivation technologies of most cereals, including the grain sorghum. It is known that most preparations, including the chemical ones, can directly or indirectly influence the development of microorganisms in the rhizosphere of plants, but the nature of their effect on the microbiota of grain sorghum rhizosphere has not been studied enough, which reasoned the relevance of this research. Microbiological activity of the grain sorghum rhizosphere (hybrid Milo W) was studied during 2019–2020 under the treatment by the herbicide Citadel 25 OD (0.6; 0.8 and 1.0 l/ha), plant growth regulator Endophit L1 (30 ml/ha) and biological preparation Bioarsenal (800 g/ 100 kg). The analysis of the obtained experimental data showed that use of the studied preparations both separately and in different compositions had a stimulating effect on the number of grain sorghum rhizosphere microbiota, which was observed in its increase, especially in variants with the combined use of the herbicide Citadel 25 OD, plant growth regulator Endophit L1 and the biopreparation Bioarsenal (compared to the control the number of rhizosphere microbiota increased by 29.4–80.6% in average by groups).

State Support

The goal of organic agricultural production is to provide humanity with high-quality food without genetically modified organisms and to support the sustainability of society. It is noted that the many benefits of organic agriculture make us think about the prospects for the development of global agriculture as one of the key factors influencing the future of the next generations. n this article we outline the main stages of evolution in the organic farming sphere and emphasize the characteristics that are relevant to each stage; define the term “organic farming” specified for Canadian and Ukrainian legislative systems. This paper also highlights the main prerequisites for the need for state support for organic production in the world on the example of two big organic producers – Canada and Ukraine. Based on the main indicators of the current state and level of development in both countries, the need for government regulation, support, and stimulation are considered. The main approaches to the stimulation and development of organic production in Canada are considered in order to determine priorities for Ukraine. It is established that subsidies for organic agriculture in Canada at one time gave an extremely important impetus to the development of this area of agricultural production, which ultimately led to significant progress in environmental protection, climate change mitigation, health, development of rural areas, and consumer protection. Also, it gave a significant boost for the national farmers, so they could grow in the area and improve their farming activity using innovative technologies. The domestic experience of financial and organizational and legal support of the organic sphere at the state and regional levels for the formation of areas for improvement is analyzed. The necessity of not only direct financial state support, but also active educational, research, and organizational support together with representatives of the active community and business has been proved. It was recovered that the main problems of the development of organic farming in Ukraine and obstacles to the formation of green policy in the field of agriculture include the following: lack of state control and statistical reporting of production, circulation, and sale of organic production; - lack of developed infrastructure in the organic sector of the agricultural sector; - imperfection of the system of certification and labeling of organic products, inconsistency of these processes with European standards; - lack of state support programs for organic producers and an insufficient number of local support programs. The necessity of a systematic approach to the stimulation and development of the domestic organic sphere to ensure the sustainability of the agricultural sector of Ukraine is substantiated. It is established that the policy of organic support in our country is not yet characterized by a high level of system and consistency, but important initial steps have been taken in the areas of organizational, legal, and financial support of organic production.

Introduction. Plant growth-promoting rhizobacteria have been successfully inserted in agriculture, aiming to find a better balance between agricultural production and environmental protection. However, there is a restriction on its application concerning the exploited species since the focus is on large-scale grain production, practically excluding small and medium-sized farms. Literature. Studies on the application of Azospirillum bacteria in horticultural species are still scarce, compared with those aimed at grain production. However, it appears that these bacteria are beneficial to the development and production of vegetables, whether they produce leaves, stems, bulbs, flowers, fruits, roots, or tubers, and may result in monetary gains, especially for small and medium agricultural producers. Conclusions. The use of Azospirillum bacteria to increase the quality and quantity of products from horticultural species and establish an environmentally friendly practice is a reality. However, the development of research that defines the best strategies for using this technology must be carried out continuously, aiming at the best conditions for producers.

AbstractThe agri-environment economy provides a significant database for environmental policy decisions. The prioritization of an actionable behavior regarding the agri-environment vulnerabilities, favors the orientation of the agriculture through more environmentally responsible methods, represents a current trend, with a broad support within the Common Agricultural Policy (CAP). The promotion of an agricultural model capable of ensuring its own sustainability implies the existence of a set of common values and rules in which to buy as many producers as possible, with a common objective, respectively to reduce greenhouse emissions and to promote an ecological responsibility of the production model. Agriculture can significantly contribute to achieving the objectives of reducing the negative effects of climate change, not only from the perspective of ensuring the conservation of carbon reservoirs, which are still present in the soil, or by expanding their size and favoring the formation of humus, but in particular by reducing the consumption of energy needed in agricultural production and the supply of biomass needed for renewable energy production., much greener. The transition to a low carbon economy, more environmentally responsible, in the national agricultural sector can contribute, both to the significant increase of food security, but also to the optimization of the agricultural production structures, which will thus conform more easy to environmental requirements. It becomes primarily the role of implementation in agriculture of feasible standards more environmentally friendly, and environmentally friendly in this context, the research in the field and the continuous training acquiring new values. An important role is played by the implementation of best practice methods in the proper management of the land and the promotion of organic production models can significantly contribute to increasing the carbon absorption in the soil and, at the same time, to indicate possible improvments in their performance.

The article presents the genetic characteristic of the Chukchi reindeer breed. The object of the study was of the Chukchi reindeer. In recent years, the number of reindeer of the Chukchi breed has declined sharply. Reduced reindeer numbers could lead to biodiversity loss. The Chukchi breed of deer has good meat qualities, has high germination viability and is adapted in adverse tundra conditions of Yakutia. Herding of the Chukchi breed of deer in Yakutia are engaged only in the Nizhnekolymsky district. There are four generic communities and the largest of which is the agricultural production cooperative of nomadic tribal community «Turvaurgin», which was chosen to assess the genetic processes of breed using microsatellite markers: Rt6, BMS1788, Rt 30, Rt1, Rt9, FCB193, Rt7, BMS745, C 143, Rt24, OheQ, C217, C32, NVHRT16, T40, C276. It was found that microsatellite markers have a wide range of alleles and generally have a high informative value for identifying of genetic differences between animals and groups of animal. The number of identified alleles is one of the indicators of the genetic diversity of the population. The total number of detected alleles was 127. The Chukchi breed of deer is characterized by a high level of heterozygosity, and the random crossing system prevails over inbreeding in the population. On average, there were 7.9 alleles (Na) per locus, and the mean number of effective alleles (Ne) was 4.1. The index of fixation averaged 0.001. The polymorphism index (PIC) ranged from 0.217 to 0.946, with an average of 0.695.

Reversible phosphorylation is a major mechanism for regulating protein function and controls a wide range of cellular functions including responses to external stimuli. The plant-specific SNF1-related protein kinase 2s (SnRK2s) function as central regulators of plant growth and development, as well as tolerance to multiple abiotic stresses. Although the activity of SnRK2s is tightly regulated in a phytohormone abscisic acid (ABA)-dependent manner, recent investigations have revealed that SnRK2s can be activated by group B Raf-like protein kinases independently of ABA. Furthermore, evidence is accumulating that SnRK2s modulate plant growth through regulation of target of rapamycin (TOR) signaling. Here, we summarize recent advances in knowledge of how SnRK2s mediate plant growth and osmotic stress signaling and discuss future challenges in this research field.

Abstract Field experiments were conducted in the growing seasons of 2017 to 2018 and 2018 to 2019 to evaluate the competitive effects of rattail fescue [Vulpia myuros (L.) C.C. Gmel.] in winter wheat (Triticum aestivum L.) and to assess whether delayed crop sowing and increased crop density influence the emergence, competitiveness, and fecundity of V. myuros. Cumulative emergence showed the potential of V. myuros to emerge rapidly and under a wide range of climatic conditions with no effect of crop density and variable effects of sowing time between the two experiments. Grain yield and yield components were negatively affected by increasing V. myuros density. The relationship between grain yield and V. myuros density was not influenced by sowing time or by crop density, but crop–weed competition was strongly influenced by growing conditions. Due to very different weather conditions, grain yield reductions were lower in the growing season of 2017 to 2018 than in 2018 to 2019, with maximum grain yield losses of 22% and 50% in the two growing seasons, respectively. The yield components, number of crop ears per square meter, and 1,000-kernel weight were affected almost equally, reflecting that V. myuros’s competition with winter wheat occurred both early and late in the growing season. Seed production of V. myuros was suppressed by delaying sowing and increasing crop density. The impacts of delayed sowing and increasing crop density on seed production of V. myuros highlight the potential of these cultural weed control tactics in the long-term management programs of this species.

Terrestrial plants evolution occurred in the presence of microbes, the phytomicrobiome. The rhizosphere microbial community is the most abundant and diverse subset of the phytomicrobiome and can include both beneficial and parasitic/pathogenic microbes. Prokaryotes of the phytomicrobiome have evolved relationships with plants that range from non-dependent interactions to dependent endosymbionts. The most extreme endosymbiotic examples are the chloroplasts and mitochondria, which have become organelles and integral parts of the plant, leading to some similarity in DNA sequence between plant tissues and cyanobacteria, the prokaryotic symbiont of ancestral plants. Microbes were associated with the precursors of land plants, green algae, and helped algae transition from aquatic to terrestrial environments. In the terrestrial setting the phytomicrobiome contributes to plant growth and development by (1) establishing symbiotic relationships between plant growth-promoting microbes, including rhizobacteria and mycorrhizal fungi, (2) conferring biotic stress resistance by producing antibiotic compounds, and (3) secreting microbe-to-plant signal compounds, such as phytohormones or their analogues, that regulate aspects of plant physiology, including stress resistance. As plants have evolved, they recruited microbes to assist in the adaptation to available growing environments. Microbes serve themselves by promoting plant growth, which in turn provides microbes with nutrition (root exudates, a source of reduced carbon) and a desirable habitat (the rhizosphere or within plant tissues). The outcome of this coevolution is the diverse and metabolically rich microbial community that now exists in the rhizosphere of terrestrial plants. The holobiont, the unit made up of the phytomicrobiome and the plant host, results from this wide range of coevolved relationships. We are just beginning to appreciate the many ways in which this complex and subtle coevolution acts in agricultural systems.
