Poultry is the most preferred meat in the current market of animal products. However, such changes in the liver, as adipose degeneration and haemorrhage can be recorded on 35 days after the slaughter. Therefore, to prevent destructive changes in internal organs, especially in the liver, various feed additives are used. In our test, we used Productive Hepato to prevent fatty infiltration and other liver damage, deficiency of B vitamins and essential amino acids and to mitigate the effects of stress. The method for determining safety of meat products was histological analysis, which evaluated the state of structural elements of muscle tissues and internal organs. 7-day old chickens were divided into 2 groups, 10 animals each. The control group did not receive the feed additive, the test group received 1 ml of Productive Hepato per 1 L of water within 5 consecutive days. The animals were slaughtered at the age of 42 days. Samples were taken within 30 minutes after the slaughter. Morphologically the liver corresponded to the physiological norm both in the test and control group. It indicated the safety of products. However, the liver of the chickens of the test group did not show any signs of adipose degeneration unlike the liver of the chickens of the control group. It demonstrated the high efficiency of the feed additive.

Nowadays, when constructing and building pig complexes, much attention is paid to the composition of swine breeding stock, which provides products that meet modern requirements of manufactures and consumers of meat products. For this purpose, the efficiency of French Pietrain boars at the final stage in the hybridization system was studied, since the impact of breed has not been fully studied. The study was conducted in the swine complex «Mashkino» Ltd. in Moscow region, Kolomensky district in 2016-2018. Four groups were formed. The first group consisted of purebred young pigs of Large White breed, the second one consisted of two-breed hybrids (Large White x Landrace), the third group consisted of three-breed hybrids (Large Whitex Landrace x Pietrain) and the fourth group consisted of three-breed hybrids [(Large White x Landrace x Pietrain) x Pietrain]. The animals were divided into the groups according to their sex, age, body weight, etc. After the animals gained 95-105 kg, they were slaughtered to study the meat productivity of the pigs and physicochemical indicators of the meat obtained. The study results showed that two-breed and three-breed hybrids had outperformed the purebred pigs both in the maximum yield of the carcasses and morphological composition, the content of the muscle tissues of the whole carcass and its individual parts had increased, while the content of the fat had significantly decreased.

One of the vulnerabilities of poultry farms is a hatchery, since microorganisms can survive the entire incubation period, they penetrate through the eggshell, infect embryos, thereby reducing egg hatchability and causing the mortality in the first days. The efficiency of different methods (aerosol spraying and «cold fog» method) for disinfecting hatching eggs with «Anolyte ANK SUPER» was studied. To conduct the test, eggs were divided into 3 groups, one was control group, the others were test groups, each group consisted of 90 eggs, the parent stock was meat chicken breeds, Ross-308, at the age of 54 weeks. The eggs were treated in a special chamber equipped with input and exhaust system of ventilation. The eggs of the first group were treated with a 37% aqueous solution of formaldehyde twice by aerosol spraying. The eggs of the second and third groups were treated with «Anolyte ANK SUPER» twice (for the first time - not later than two hours after the laying, and then before placing the eggs into the incubator). The disinfecting agent was used at the dose of 30 ml per 1 m3 of chamber, the second group was treated by aerosol spraying, and the third group was treated by «cold fog» method with a power generator (model 2610). The mode and exposure of treatments were similar in all groups. Samples to conduct a bacteriological test for the total bacterial count (TDC), E.coli and Salmonells were taken before and after the treatment. The use of the disinfecting agent by both methods, decreased the bacterial and increased the egg hatchability by 1.2-5.8%.

The fishing industry is the most important branch of the national economy of the Sakha Republic. Therefore, the study of fish diseases and the development of preventive measures are the leading trends in the fishing industry.

The article presents the research data on the study of the influence of different methods of treatment of sunflower crops in the dry steppe zone of the West Kazakhstan region. The aim and objectives of the research are to study the elements of adaptive sunflower cultivation technology in order to provide producers of vegetable oil with high-quality raw materials. To obtain high sunflower yield it is very important to choose the correct seedbed preparation. As a result of the research, the productivity of sunflower was established depending on the methods of crop treatment. In our studies, the greatest weediness of sunflower crops was in variants without the use of herbicides. The lowest number of weeds (19 pcs./m², with the wet weight of 36 g/m²) was recorded in the variant with the administration of the herbicide Roundup with the combination of harrowing and pre-sowing cultivation. The different methods of treatment also had an effect on the size of the above-ground biomass. The highest biomass was observed in the variant with herbicidal technology (6.05 t/ha), the lowest one - in the control (4.65 t/ha). The highest yield of sunflower seeds (2.35 t/ha) was recorded after the administration of Roundup and harrowing with pre-sowing cultivation. In the control variant this indicator was 1.79 t/ha. The yield in the variant with harrowing, pre-sowing cultivation and one inter-row cultivation was 1.85 t/ha; it increased by 0.06 t/ha in comparison with the control variant. As shown by the research data, the yield of sunflower in the dry steppe zone depended on adaptive technology. At the same time, the highest productivity of sunflower was established during cultivation harrowing + presowing cultivation with the administration of Roundup (2 L/ha).

The concept of the storage stability of sugar beet has been considered. Four factors were included in the checklist of storage stability: determining breeding characteristics of hybrids; the physical state of the roots; conditions and duration of storage. The factor characterizing the breeding peculiarities of hybrids is reflected by the selection type, which is presented by the yield, normal and sugary. The factor characterizing the post-harvest physical condition of root crops includes indicators of the content of root crops with strong mechanical damages, the degree of their withering. The factor that determines the storage conditions has a qualitative expression of the regime formed through the technologies used, including storage in open areas in natural conditions or with methods of shelter and forced ventilation. The factor of storage duration is expressed by the duration of the period, which is based on the actual shelf life took different in the polar variants 3 times. To determine the levels of life processes in sugar beet during storage, a computational experiment was conducted on the basis of five indicators of four factors at three levels of variation. A criterion for the storage stability of sugar beet was proposed, which is an integral indicator characterized by a combination of immune, physiological and biochemical properties of root crops. The information obtained about storage stability of sugar beet can be used to determine the optimal shelf life of root crops and differentiation of each batch of raw material in terms of duration and conditions of storage. To determine the levels of life processes in sugar beets during storage, a simulating experiment was conducted on the basis of five indicators of four factors at three levels of variation. The chosen categories of the storage stability of sugar beets are characterized by different intensity of processes occurring in root crops and the following storage results: high storage stability (the criterion of storage stability is 8.0-10.0 points); average storage stability (criterion of storage capacity is 5,0-7,9 points); low storage stability (criterion of storage stability is 2.0-4.9 points); no storage stability (the criterion of the storage stability is 0-1.9 points). For practical application, the storage stability is proposed to be expressed in the form of a criterion calculated on the basis of a multiple regression equation, with subsequent allocation of the relevant categories of storage stability. This will allow to truly identify raw materials with a high level of storage stability, assuming low weight loss of beet and sucrose during long-term storage.

In Uzbekistan, the production of vegetables is much higher than consumption, but the range needs to be expanded. The family Brassicaceae plays an important role in the organization of healthy diet. Of special interest is broccoli, which is widely used in many countries, but hardly cultivated in Uzbekistan. The study to select the best hybrids and determine its planting time was conducted in 2015-2017. The subjects of the study were 7 hybrids of broccoli and 1 hybrid of cauliflower, and 6 planting dates. In the variety testing, the standard was Fiesta F₁. As a result of the study, it was established that Lucky F₁, Coronado F₁ and Strombili F₁ entered the fruiting stage first (97 days after the emergence of seedlings). Strombili F₁ demonstrated the longest fruiting period (70 days), Hallmark F and Belstar F₁ - the shortest one (39-41 days). Hallmark F₁ was the most productive hybrid, the yield of the central heads exceeded Fiesta F₁ by 64.4%, and the total - by 46.65. Of the 6 tested planting dates from July 25 to August 15, the largest harvest was obtained during the period of 5-15 July. The optimal dates for the summer planting were 5 and 15 July. The last acceptable planting date was 5 August. To ensure the conveyor flow of fresh products in autumn, broccoli should be planted from 25 June to 5 August.

In recent years, the area under oil crops has been significantly increasing, in particularly it concerns flax. At the same time the demand for information on the technology for the protection of flax from pests has also increased. The available information is not fully covered, over time, there have been tangible changes in the composition of pests of agrobiocenosis. Information from foreign sources is not always applicable under the conditions of our republic and requires verification by practice. In this regard, the main purpose of our research was to study the species composition of pests of flax in Kashkadarya, Samarkand and Jizzakh regions of Uzbekistan (2015-2017). To identify the species composition of pests, the method of route examination of flax was used. As a result of the research, it was established that flax had been affected by 16 species of insects belonging to 7 families and 4 orders. The description of main pests of flax was given

The impact of the type of crop rotation, method of basic tillage, manure and mineral fertilizers on the yield and economic indicators of winter wheat was studied in the field stationary experiment in the forest-steppe zone of the Central Chernozem Region. When comparing different methods of basic tillage, the crop yield was almost at the same level for twenty years, that was confirmed by the indices of least significant differences. But among different crop rotation, the grain fallow rotation showed the highest productivity. The yield in summer fallow rotation was 4.31 t/ha, the yield, where predecessor of wheat had been pea, was 4.00 t/ha and the yield in the gain-grass rotation was 3.94 t/ha. In comparison with the absolute control, the administration of one dose of mineral fertilizers (N₁₀P₂₆K₂₆) increased the yield of winter wheat by 30-35%, the double dose increased the yield by 41-48%. The administration of organic fertilizers at the dose of 40 t/ha increased the yield by 13-19%, and 80 t/ha - by23-28%. The maximum yield of winter wheat (5.13 t/ha) was obtained in the grain fallow rotation after the administration of N_18Р120K₁₂₀ against the background of the after-effect of 80 t/ha of manure. The high indicators of net income and profitability was also obtained with summer rotation; the net income was 26.9-27.4 thousand rubles/ha depending on soil cultivation, the profitability was 191-199%. The lowest economic indicators were obtained with the rotation with perennial grasses, the net income was 22.7-23.0 thousand rubles/ha, the profitability was 159-166%. The net income after the administration of organic fertilizers increased with the degree of fertilization, and it decreased after the administration of certain amount of mineral fertilizers. That was recorded in all crop rotations, regardless of the tillage method. The trend of the yield of winter wheat is positive, with all the combinations of studied factors, the yield increased from the second rotation to the fifth.

The paper presents the results of the study on changes in the main agrochemical indicators of soil fertility during long-term agricultural use. The region is characterized by meadow-sierozem, gray-brown, meadow-gray-brown, alluvial-meadow, swampy-meadow and solonchak soils. Granulometric composition, humus, absorbed calcium, magnesium and sodium, as well as nitrogen, phosphorus and potassium nutrients were determined in soil samples. It was established that changes in granulometric composition had occurred under the influence of irrigation and had depended on the source of irrigation water, time of irrigation, accumulation of irrigation sediments and its lithological composition. Intensive use of land has led to a decrease in the humus content. The humus content in these soils is insignificant. The humus content in meadow-sierozem soils was 2.0-2.5% in a 0-20 cm layer, 1.5-1.7% in a 0-50 cm layer, 1.0-1.25 in a 0-100 cm layer. In light meadow-sierozem this indicator was 1.6-1.8% in a 0-20 cm layer, 1.1м1.5% in a 0-50 cm layer, 0.7-0.9% in a 0-100 cm layer. These soils had low indicators of humus content. These soils are also poor in mobile phosphorus and exchangeable potassium. Calcium dominated among the absorbed cations. If there was less than 5% of absorbed Na in the soil absorption complex, the solonetzicity of the soil was not observed. To regulate the amountand ratio of absorbed bases, it is necessary to administer chemical ameliorants, properly perform plowing and use scientifically grounded land development.

The article gives the results of studies on the effect of fertilizers on the yield and quality of grapes in the Ganja-Kazakh zone of Azerbaijan. The Ganja-Kazakh region is one of the most important sustainable developing agrarian economic regions of Azerbaijan. Grapes have been one of the main crops of this region and its cultivation area has been expanding every year. The research was conducted in «Amin» of the Samukh region located in the western part of Azerbaijan in 2015-2017. The soil of the experimental site is carbonate, gray-brown (chestnut), medium-heavy-scraggy. The research was carried out on Tabrizi grapes. The rational use of fertilizers is one of the important conditions for modern agriculture, because it ensures high yields. Recently, there has been a tendency toward the rational use of mineral fertilizers used both separately and together with organic fertilizers. In the republic, the cultivation areas of table grapes have been growing every year, the technology of their production has been improved, and the profitability has been increasing. The highest yield and qualitative indices were obtained in the following variant: background + N₉₀P₁₂₀K₉₀ - 172.5 c/ha, increase in yield in comparison with the variant without fertilizers - 59.5 c/ha or 71.7% of grapes, sugar content - 18.6 g/100 cm³, titratable acidity - 5.2 g/dm³ and nitrates - 49.6 mg/kg. At the same time, the nitrate content did not exceed the limit of the allowable concentration (60 mg/kg in wet weight). Studies have established that, in order to obtain high-quality harvest of table grapes and restore fertility of the soil in this zone, fertilizers should normally be used in the following quantity: 10 t of manure per ha + N₉₀P₁₂₀K₉₀^kg/ha.

Diesel engines have been widely used for motor-and-tractor equipment. A nozzle is the most important device of the diesel power supply system. Analysis of the thermal state of spray nozzles provides the information on the operation process. It provides a basis for improving the internal combustion engine systems. The thermal state of spray nozzles has a significant impact on the efficiency and reliability, it can be estimated by an experimental or theoretical calculation method. In relation to the unification of pintle and multi-jet nozzles regarding a swirl-chamber diesel, the analysis of the thermal state was conducted. The calculation determined the distribution of the fuel temperature during the passage of the sprayer in a steady state mode at the nominal load. The highest design temperature of the spray nozzle was 192-220 °C. At the same time an increase in the pressure of fuel injection from 13 to 17 MPa reduced the temperature by 15-19 °С °(from 215 to 198 °С). Low-density fuel significantly reduced the design temperature along the entire length of the sprayer by increasing heat dissipation from the nozzle to the fuel. So, the design temperature at the injection pressure of 15 MPa was 212 °С for the fuel with the density of 850 kg/m³ and 199 °С for the fuel with the density of 810 kg/m³.
