In all the studied groups of sheep, A and B allelic variants of the GDF9 gene, alleles A and B of the GH gene were established. The analysis of the data revealed a breed aspect in the distribution of the frequency of alleles and genotypes of the GDF9, GH genes in the populations under consideration. Conclusion. The results of the study of the genetic structure of the populations of sheep of the Volgograd and Edilbaevsky breeds showed that the frequency distribution of alleles and genotypes of the growth hormone (GH) and differential growth factor (GDF9) genes have some features associated with the breed affiliation of the studied sheep.

Features of the use of information technologies in agriculture

The article shows the features of the use of information technology in the agricultural sector of the economy. The main information technologies used for the innovative development of the country’s agriculture in recent years are considered. It was revealed that one of the factors of effective agricultural production is the use of modern information technologies, and this is not only computer technologies (equipment and software) for the production and storage of information, but also technologies associated with the transfer of information. The questions of the use of resource-saving technologies in agriculture have been studied in details.

Comparative analysis of the efficiency of application of different methods of tillage in the system of resource-saving agriculture technologies

Relevance. The article presents a comparative analysis of methods of basic tillage-classical dump plowing and technologies of minimal and no-till tillage. Question about the benefits of minimum and zero tillage on intensive up to the present time remains controversial. However, minimum and zero tillage systems are becoming increasingly common in the world as a response to increasing degradation and reduced soil productivity.Methods. Various publications on this topic were analyzed. Various studies show mixed results.Results. The analysis shows the following advantages of minimum and zero processing: costeffectiveness; prevention of soil erosion; maintaining fertility in the upper soil layer; preservation of soil moisture and vertical soil structure. The use of resource-saving technologies can not only preserve soil fertility and reduce the economic costs of its cultivation, but also prevent the degradation of farmland caused by erosion processes. Resource-saving technologies mean not only the abandonment of annual moldboard plowing, but also leaving crop residues on the field, the use of integrated weed control measures, the use of scientifically based crop rotations. Failure to meet these conditions will negate the effectiveness of minimum tillage. Minimum processing continuity is of particular importance. Any soil cultivation in the transitional phase means a return to the initial phase, and this should not be allowed. To ensure high productivity of resource-saving technologies, it is necessary to apply a well-grounded crop rotation system. An important factor in the use of resource-saving technologies in agriculture is economic efficiency. As experience shows, at the same yield level (20 cwt / ha), profitability with resource-saving technologies reaches 93.7%, while with a usual one — 55.4%. A comparative analysis of the methods of basic tillage shows that the advantages of minimal and no tillage are possible only in the presence of a high culture of agriculture. These advantages are as follows: cost-effectiveness; prevention of soil erosion; maintaining fertility in the upper soil layer; preservation of soil moisture and vertical soil structure.

Application of resource-efficient technologies in the framework of lean management of industrial enterprises

The article deals with the problem of processing Apple waste in production. It is shown how efficiently food production can be organized with the least losses and costs. It is proved that the technogenic type of development formed in the world economy, which does not sufficiently take into account the environmental and social costs of economic activity, reproduces the problems and dangers that threaten human civilization. Humanity is caught in a vicious circle: to create comfortable living conditions, it is necessary to increase the volume of gross domestic product, which requires more and more resources (primarily mineral), and their extraction, processing and consumption cause serious damage to the environment, contributing to the deterioration of living conditions and the growth of diseases, which negates efforts to create living comfort, and threatening climate change can make life on Earth itself problematic. Within the framework of lean management, the effectiveness of the process of obtaining Apple powder from waste is considered. Development of technologies for processing Apple pomace is an important task, the solution of which is necessary for the improvement of economic indicators of resource efficiency main by-products of fresh Apple pomace in the form of pectin containing products (extracts, pastes, powders, gelling concentrates); canned fruit (pur?ed foods, jam, secondary juice); drink (alcoholic and nonalcoholic); Apple powder; phenolic compounds; products of fermentation (food grade organic acids, enzymes, high-protein animal feed), etc. The use of resource-saving technologies will help strengthen the competitive advantages of industrial enterprises.

Synthesis and properties of ion-exchange materials based on hydrolysis lignins

Hydrolytic lignin is a large-tonnage waste product of ethyl alcohol production and is a renewable resource. The structure of lignin is characterized by the presence of a large number of hydroxyl groups, which provides the value of lignin as a raw material for synthesis in polymer chemistry. But due to their low chemical stability in dilute alkalis, acids and solvents, lignins are of little use for wide practical use. The introduction of additional functional groups into the lignin maromolecule by oxidative modification with the use of resource-saving technologies makes it possible to obtain new products for the synthesis of composite materials. On the basis of electrochemically modified lignin in polycondensation reactions with phthalic acid, ion-exchange materials have been obtained: weakly acidic cation exchangers with a exchange capacity of 0.1 mol/l NaOH 3.5-3.8 mmol/cm3, capable of sorbing cations in a wide range of pH values, and ampholyte (exchange capacity for sodium cation 6.4-6.6 mmol/cm3, for chlorine anion - 1.1-1.3 mmol/cm3). Ion exchangers synthesized on the basis of chlorine and nitro-containing lignins have been investigated in comparison with generally known industrial ion exchangers; they have high exchange and physic-mechanical characteristics and chemical resistance.

FEATURES OF FORMATION THE COSTS OF THE ORGANIC CROP PRODUCTS PRODUCTION

Improving the efficiency of agricultural production while reducing the anthropogenic load on the environment and natural resources can be achieved through the development of organic production as an alternative model of management. Unlike other methods of agriculture, organic production is based on the use of resource-saving technologies, minimization of mechanical tillage and eliminates the use of synthetic substances. The priority for organic agriculture is the use of materials and technologies that improve the ecological balance in natural systems and contribute to the creation of sustainable and balanced agro-ecological systems. The peculiarity of organic production is that the production, processing, packaging and storage of products are subject to certification by the relevant authorized institutions. The lack of own national standards for organic products necessitates certification with the help of international standards and national standards of other countries. Under such conditions, the products obtained are exported mainly to the countries of jurisdiction of the companies that have authorized the relevant certification bodies. In addition, the development of domestic organic production is complicated by the underdevelopment of the regulatory framework. Organic production allows implementing the concept of balanced development of the agricultural sector on the basis of socio-economic, natural resource balance and aims to provide society with safe and quality food, as well as preserving and improving the environment. The main goal of an organic agricultural enterprise, along with the production of organic products and meeting consumer demand, is to maximize profits. Profit generation is a continuous process that includes a set of actions to ensure the coordination of income and expenses of the enterprise in order to obtain and maximize their positive balance. Costs are the main limiter of profit and at the same time the main factor influencing the supply of organic products. The lack of developed standard documents for accounting for the costs of production of organic crop products necessitates the independent formation of a package of primary documents by business entities. At the same time, the standards of organic production, the requirements of current legislation on the production, circulation and labeling of organic plant products, the technology of its production must be taken into account. When determining the cost items, it is necessary not only to competently form their structure, but also to give comprehensive characteristics of the composition of each item. This is especially true of the specific costs of organic production. The use in practice of accounting for the proposed nomenclature of cost items will allow differentiating the costs provided by the technological conditions of organic production and allowed by law and the costs of which there are certain restrictions. This, in turn, will improve the information support of the control function of organic production management and provide an opportunity to reasonably calculate the cost of organic crop production.

ЕКОЛОГІЗАЦІЯ ТУРИЗМУ ЯК УМОВА СТАЛОГО РОЗВИТКУ

The rapid development of the tourism industry leads to increased pressure on tourism resources and the growing contradictions between meeting tourist demand and the rational use of tourism resources. Since most types of tourism are carried out in the natural environment, it is extremely important to preserve natural tourist resources, their rational use and restoration. This task is solved by greening tourism, that is, the transition to ecologically balanced use of nature in tourism, the implementation of ideas of sustainable development. It is shown that the greening of tourism requires the consolidation of efforts of the state, tourism enterprises and tourists aimed at reducing the negative anthropogenic impact on the environment, natural and historical and cultural tourism resources. Among the main tasks to be solved on the way to sustainable development of tourism are the implementation of environmental regulations, environmental management, introduction of non-traditional, renewable energy sources, ecological modernization of existing energy sources, use of resource-saving technologies, improvement the functioning of tourist infrastructure, increase environmental literacy of tourism workers, travel organizers, development of environmental tourism product, use of environmental education and educational potential of natural areas in order to increase the environmental awareness of citizens and implementation of environmentally friendly tourism development programs, reduction of recreational load on natural objects, implementation of greening of tourist infrastructure, involving the general public and tourism industry to participate in environmental activities.

Peculiarities of formation the grain productivity of spring barley depending on terms and norms of foliar fertilization.

One of the ways to improve the nutritional conditions of plants and therefore increase the productivity of agrocenoses of spring cereals, is the use of mineral fertilizers, both in their main application and in the spring fertilization of vegetative plants. And that is why the purpose of study was to improve agro-technical measures for growing spring barley, which would be based on the use of biological potential of the crop and the use of resource-saving technologies in the Northern Steppe of Ukraine. The study was conducted at the Erastivka Experimental Station of SI Institute of Grain Crops of NAAS during 2017–2019, according to generally known methods. Soil of experimental field – ordinary chernozem, low-humic, loamy. The humus content in arable soil layer (0–30 cm) – 4,0–4,5 %, total nitro-gen – 0,23–0,26 %, phosphorus – 0,11–0,16 %, potassium – 2,0–2,5 %, pH of water extract – 6,5–7,0. Field experiments were laid in six-field crop rotation after predecessor winter wheat. In experi-ments seeded spring barley of variety Stalker with seeding rate 4,5 million of grains/ha. Soil prepara-tion, sowing, care of crops and harvesting were carried out strictly according to the zonal recommendations. Variants in a field experiment designed systematically, with three replications. Accounting plots area – 25 m2. Arid conditions of Ukraine’s Steppe zone is quite complex. Two-thirds of land in Ukraine referred to zone of risky agriculture, but even here you can use 30–50 % and more of varieties capacity, in consideration of importance the local gene pool in creating highly adapted varieties based on local varieties and using the developed agrotechnical growing measures, that promotes plants to be resistant to dry conditions of Steppe zone of Ukraine. Weather conditions during the investigation were different, which made it possible to fully assess its impact on grain productivity potential of spring small cereals. Phenological observations, analysis of yield structure elements and grain productivity of spring barley of variety Stalker when grown without fertilizers and fertilizing with N30P30K30 as well as the use of different terms and doses of foliar fertilization of plants with ammonium nitrate and humic preparation humisol plus in conditions of Steppe zone of Ukraine are presented. It was found that the growth, development and formation of productivity elements of spring barley plants were significantly influenced by the timing and dosing of fertilization. Earlier fertilization of plants with ammonium nitrate and humisol plus, carried out on seedlings and in the tillering phase, contributed to better plant growth and development, formation of productive tillering and yield structure elements, compared with fertilization in the phase of stem elongation as in the variant of fertilized background (N30P30K30), as in the variant without the using of mineral fertilizers. Key words: spring barley, mineral fertilizers, foliar fertilization of plants, elements of head structure, grain yield.

ЭКОЛОГИЧЕСКИЙ СПОСОБ ВОЗДЕЛЫВАНИЯ СТОЛОВОЙ СВЕКЛЫ В ГОРНОЙ ЗОНЕ РСО – АЛАНИЯ

In the context of the limited use of technogenic resources to regulate agricultural crops productivity of and soil fertility, the cultivation of varieties and hybrids that are resistant to abiotic and biotic stressors acquires a special role. In this regard, the organization of adaptive vegetable growing is of importance, for it provides for the creating highly productive agrocenoses that most fully realize the bioclimatic resources of the region, as well as for the use of resource-saving technologies. Our research is aimed at optimizing biologized soil-protective crop rotations in the mountainous zone in order to achieve an increase in crop productivity and preserve soil fertility. The studies were carried out in the mountainous zone of North Ossetia – Alania on mountain meadow soils. The influence of the biological product and micronutrient fertilization on the biological parameters of soil fertility in beet crops showed that the maximum loss of flax tissue was observed when seeds were inoculated with a 2% solution of "Extrasol" (29.6%). The enzymatic activity of the soil was higher in the variants with the use of a biological product and microfertilizer: the activity of catalase – by 0.2–0.5 ml of О2 per 100 g of soil, phosphatase – by 0.1–0.3 ml of Р2 О5 per 100 g of soil. The yield increase from the introduction of "Extrasol" and "Kristalon" on the crops of table beet is 0.8–1.6 t/ha. The profitability from the use of the Extrasol biological product and the Kristalon micronutrient fertilizer was 75.1–120.8%. Thus, for the efficiency of farming in mountainous land-poor areas, one should take a differentiated approach to the choice of crops and territories in which they are grown. The implementation of this approach fully meets the conditions for land use in mountainous areas and household plots.

Peculiarities of forming a root system of plum seedless in a fruit kennel with drip irrigation

Relevance. Currently, there is a problem of satisfying the demand in the domestic market for fruit and berry products in accordance with current recommendations. One of the ways to intensify agricultural production is the use of resource-saving technologies, which include drip irrigation. The issues of regulating the water balance of the soil when growing planting material for fruit crops in modern conditions require experimental studies aimed at studying the biological characteristics of economically important plants and their reactions to the complex of external environmental factors. Methods. Field studies were conducted on the territory of the educational experimental farm of the Michurinsky Garden fruit growing laboratory of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy. A two-factor experience in the study of different ranges of moisture for the formation of varietal plum seedlings grafted on plum tree stock was laid in the spring of 2018. The first factor included options for maintaining soil moisture in the range of: 1) 60-80% of the lowest moisture capacity; 2) 70-90% of the lowest moisture capacity; 3) 80-100% of the lowest moisture capacity; 4) control (without irrigation). Plum varieties “Mashenka” and “Utro” were the second factor. Results. Constructed humidification contours according to the years of research and experimental options showed that drip irrigation contributes to the optimum moisture concentration in the soil for seedlings. The most developed root system compared with the control was obtained on irrigated options with maintaining humidity in the range of 70-90 and 80-100% of the lowest moisture capacity. Here, the maximum values of the volume of the root system, the number of roots and the average root length are obtained. It was revealed that in the variants with irrigation, the root system of seedlings spreads in the upper layer (mainly 20-30 cm) and stretches along the line with droppers.
