Evaluation of the output of lime is made for three options for the use of Ferroalloy gas: when you use the physical heat of the gas; when using the chemical energy of the gas and the location of the reactor after scrubbing; when sharing of sensible heat and chemical energy of the gas. As a result of the calculation of the expected yield of lime, it was found that the use of Ferroalloy gas for the production of lime can fully provide or at least compensate for the deficit of lime in the production of steel. The technology of calcination of limestone with Ferroalloy gas is presented in the form of a cycle synchronized with the smelting of steel, including, in accordance with the gas outlet from the layer and their alternation with pauses of inter-blowing periods. The preliminary technological characteristics of firing obtained as a result of theoretical analysis are used for further experimental and theoretical studies.

Complex research is carried out on the rational use of natural pastures with seasonal use in a specific area. The research was conducted in 2015-2017 on the lands of “Batyr” farm in Korday district of Zhambyl region. The pasture lands of the farm consists of 5 independent sites and are located in 3 geographical areas: foothill-steppe (950 hа), foothill-dry steppe (1370 hа) and foothill-semi-desert (1880 hа). The total area of distant pastures is 4.200 hectares. As a result of conducting of geobotanical researches, the farm territory of peasant farm "Batyr" in Korday district of Zhambyl region was divided into seasons (spring-summer-autumn) of their use, the yield of natural herbage and live weight gain of animals was determined. Results of accounting of productivity of natural herbages on zones, seasons of year are given in article and the gain of livemass of animals for the pasturable period is defined. When determining efficiency of sheep it is revealed that higher additional weight of a liveweight is received in experimental group of animal. The seasonal pasture on average in three years of researches at the end of the pasturable period provided an increase of a live weight of rams on 3.370 kg/head at ewes on 8.020 kg/head and lambs of birth year on 8.640 kg/head is more in comparison with control groups of animals. It should be noted that for the pasturable period the increase of alive mass of animals in experimental group in 2017 is higher than a research in comparison with previous years. In 2017 at a pasture of animals on seasonal sites it was applied intra seasonal pasture turnover at which unproductive driving of animals in search of a forage on the grazing square is practically reduced three times, besides degradation of the pasturable territory is completely excluded. It was found that the use of seasonal use of pastures provides more weight gain studied animals compared to animals that graze in one place with an unsystematic manner of grazing. The implementation of the results created the conditions for the restoration of degraded pastures with an increase in the growth and development of vegetation cover up to 15-18 % and an increase in livestock production through rational grazing up to 12 %.

Today, there is a full development of the food industry. It is characterized by the widest mechanization and automation of production and transport processes, the use of artificial cold and vacuum technology, the latest physical methods, chemical and biological preparations to accelerate technological processes. There are a huge variety of new products. New ways of long-term preservation of products in hermetic airtight packaging are promising. Now it is possible to deliver products from almost any industry to anywhere in the world. But the main problem for the modern consumer is that today's food industry is moving by leaps and bounds in the application and addition of chemical food additives: preservatives, flavors, dyes, stabilizers, antioxidants and substitutes for raw materials. To correctly answer the question of how to treat the use of food with food additives, it is necessary to understand and weigh the main disadvantages and advantages of using them. Advantages are that the product is better preserved, has an attractive appearance. Disadvantages are that the human body wears out, processing various chemicals, it is harmful to health. And with certain doses of use it becomes dangerous. Everyone has their own attitude to their health and their own priorities in life. Many people have come to terms with the daily use of products with additives, but others consciously refuse almost everything in the store. But the fact that no one wants to be poisoned from an overdose of various chemicals or starve to death. Therefore, the main advice is to carefully study the composition indicated on the label of food products and know the measure of their consumption. It is also impossible to believe blindly that the label was written with the truth. Manufacturers often use additives literally visually, which can lead to the production of a product with a dangerously higher concentration. It also happens that the manufacturer intentionally exceeds the norm in order to hide the shortcomings of the product (stale, poor quality of raw materials) and increase the yield of the finished product. The food additives added to many foods (usually designated by the code E) are predominantly harmful to the body. With moderate consumption, the use of products with E-supplements is not too harmful to the body (for example, several times a month). The situation is dangerous when a person consumes products with a large number of food additives daily or even several times a day when using various products. Nowadays, there are several hundred food additives with the code E (from E100 to E1521).

Main problem: Microbial-plant relationships, including epiphytic microflora, are the subject of attention of many scientists. Numerous works confirm the high interest of researchers and the relevance of studying this topic. Despite many years of research, some questions concerning the characteristics of the epiphytic microflora still remain open. It is already a well-known fact that the epiphytic microflora is directly related to the physiological development of the plant, including yield. This is due to the close interaction of the plant with the microorganisms living on its surface throughout the entire growing season. It is also proved that epiphytic microflora has the ability to change characteristics under the influence of environmental factors (temperature, humidity, soil contamination, sunlight, etc.). In this regard, the study of this topic is one of the important areas of biological and agricultural sciences and is of high importance. It should be noted that a significant role in the development of agriculture in the Republic of Kazakhstan and the Pavlodar region is played by representatives of vegetable crops, including tomatoes and potatoes belonging to the Solanaceae family, which indicates the high importance of the plants selected for the study. The combination of the above arguments determines the need to study the epiphytic microflora of plants and establish the regularities of its influence on the adaptive properties of the studied plants of the Solanaceae family, as well as on their productivity. In turn, the study of epiphytic microflora can also contribute to the search for new ways to increase the yield of plants and their resistance to various diseases. Purpose: The article is devoted to the study of the properties and characteristics of the epiphytic microflora of the surface of various organs of plants of the Solanaceae family (on the example of tomato and potato). The variability of the composition and number of epiphytic microorganisms in seasonal dynamics is shown. Methods: bacterioscopic method, fingerprint method, flushing method, Gram staining method. Results and their significance: The characteristics and properties of representatives of epiphytic microorganisms of aboveground (leaf, fruit, flower) and underground (potato fruit) plant organs were studied. The role of the influence of environmental factors on the variability of epiphytic microflora is determined on the example of plants Lycopersicon esculentum Mill. (common tomato) and Solanum tuberosum L. (tuberous nightshade). The differences in the microflora of different plant organs in different periods of vegetation are shown.

The article is devoted to the development of a technology for obtaining organic fertilizers from poultry waste based on biocatalytic processes. Currently, many poultry farms have become sources of environmental pollution, thereby causing serious environmental problems and economic and social damage. The problem of reliable protection of the natural environment from pollution by bird droppings is currently relevant. In the area of operation of large poultry farms, air pollution by microorganisms, dust, foul-smelling organic compounds, which are decomposition products of organic waste, as well as nitrogen, sulfur, and carbon oxides, is possible. Bird droppings contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Humic substances isolated from brown coal have a sufficiently high sorption activity and are used as cheap sorbents for solving a number of environmental problems in industry. These studies are aimed at minimizing the main disadvantage of the anaerobic digestion process, the low reaction rate, which leads to the need to create large-volume bioreactors. On the basis of the research carried out, a technology has been developed for obtaining organic fertilizers from poultry waste by the method of anaerobic fermentation of chicken manure with humidity at a temperature of 27 °C - 50 °C with the addition of sodium humate. The resulting fertilizer is intended for use in agricultural production, horticulture, floriculture, forestry, municipalities, in household plots in order to increase the yield and quality of crop production. For the developed technology, an application has been submitted for obtaining a Patent for the invention of the Republic of Kazakhstan «Method for producing organic fertilizers» (priority No. 2021-22818, dated July 13, 2021). The invention allows to significantly reduce the time of fermentation, to enrich the product with organic and mineral products contained in sodium humate, to convert the salts of heavy metals into an insoluble state, to improve the environmental friendliness of the method.

The development of extraction techniques of medical plants aims to maximize the bioactive compounds production. Тechnologies in this area of industry have not high enough еfficiency factor. In some cases, it reaches only 40-50 %. Therefore, development of new methods to effectively extract different compounds from plant material and their input into large-scale industry is of great importance. The goal is to determine an effective and suitable technology for extracting bioactive compounds from medical plant. This is a narrative review paper which focuses on different extraction methods of medical plant. To find relevant articles for this narrative review, 73 articles were reviewed. Of these, 14 irrelevant documents were discarded. This review analyses various extraction processes to guide the selection of suitable methods for various types of medical plants and applications. This is done by outlining traditional and modern methods of extraction techniques, exploring the importance of solvents for extraction, and comparing novel and alternative methods of extraction. In conclusion, based on the current knowledge, solvent extraction is the most common method for medical plants extraction. Enzymatic hydrolysis and supercritical extraction are advanced techniques with high yield of compounds. However, more research is needed for some modern extraction methods.

Main problem: Bird droppings and animal manure contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Purpose: To study the effectiveness of the use of organomineral fertilizer from poultry waste, obtained using biocatalytic processes on the growth and development of plants. Methods: An application for a Patent for the invention of the Republic of Kazakhstan "Method of obtaining organic fertilizer" has been submitted for the developed technology for obtaining organic-mineral fertilizer. In the soil intended for growing seedlings of tomatoes of the “Pepper-shaped Orange” variety and peppers of the “Bogatyr” variety, the resulting fertilizer was applied in the amount of 1 kg per 1 m2 of soil, which was dug to a depth of 8-10 cm and used to grow seedlings in closed ground and subsequent for planting it in open ground. Soil without fertilization was used as a control. The process of soil preparation for open ground, intended for planting seedlings, was carried out for the experimental field with the introduction and control without fertilization. Experimental and control studies were carried out under equivalent climatic conditions, the scheme and technology of watering plants. In total, 100 bushes of each plant species were used in the experiment. Results and their significance: The use of the obtained organomineral fertilizer allows to increase the yield of vegetable crops (tomatoes, peppers) by 20-25% compared to the control. In addition, in the experimental samples, an increase in the number of fruits on a bush was noted with an increase in their size, a decrease in the growing season and the number of damaged fruits.

In this article, comprehensive studies have been conducted on the effective use of natural pastures in conditions of vertical zonality in the project territory of Batyr Korday district (Zhambyl region). The data presented shows how important it is to comply with the norms and loads of pastures for further preservation of pasture yields and prevention of degradation. Consequently, there is a need to develop effective and scientifically-based systems of pasture turnover and the introduction of measures to restore pasture lands in the Zhambyl region, taking into account the peculiarities of the climate and geo-botanical indicators. Pasture lands make up about seventy percent of the entire territory of the Republic of Kazakhstan. The potential productivity of these lands reaches twenty-five and more million tons of fodder units. Pasture is the main renewable forage plant resource. It should be emphasized that haphazard use has led to the fact that land degradation processes occur on 27.5 million hectares of pastures, feed capacity decreases, biological diversity decreases, erosion processes manifest themselves, etc. All this requires the development of science-based approaches to the exploitation of pasture resources, compliance with the basic elements of rational grazing. The current situation may have a twofold path of development. The first way is the absence of strategic initiatives for the effective use of pastures for small producers will lead to a final reduction in the feed capacity of the pastures used. And the second way is small and large-scale use of the huge forage potential of the restored pastures.

Increasing the yield of sunflower is inextricably linked with the evaluation of newly created interline hybrids and their components (parental forms) using various methods for assessing their combination ability (CА). Breeding research in this direction includes large material and practical costs when using the developed methods for assessing combination ability (CА) due to its small analytical capabilities. New approaches to the analysis of the productivity of hybrids in practical studies can significantly increase the volume of the analyzed material and evaluate not only for a short period of testing, but also for a long period of time over the years. Purpose is determination of the combination ability of parental forms of sunflower interlinear hybrids to optimize the breeding process. When analyzing the determination of the combination ability of the parental components of sunflower interlinear hybrids, the method of evaluating the CА according to a special scale developed at VNIIMK (Krasnodar, Russia) was used. This method makes it possible to analyze a large number of hybrid combinations and their parental forms and draw appropriate conclusions for further use in the breeding process. The analysis of the obtained results makes it possible to fully evaluate the obtained interline hybrid combinations by years of testing. We analyzed 1736 hybrid combinations involving 212 maternal forms and 1472 combinations involving 209 paternal pollen fertility restorer lines. 75 maternal lines with a high total combination ability (GCА) and 97 paternal forms with this trait were identified. Maternal lines with high combinational ability VKU 110 A, VKU 140 A and SV 55 A are of interest for use in practical breeding. Among the paternal forms are SV 123 V, VKU 400 V and VKU 401 V. The components of hybrid combinations with high specific combination ability (SCА) have been determined. These are lines VKU 414 A, VKU 413 A, SV 31 Rf, SP 1459. Hybrids with high adaptive properties have been identified when growing conditions change, which will make it possible to purposefully conduct practical breeding to maintain high productivity of sunflower hybrids
