Synthesis of 6-benzylaminopurine and the study of biological active properties of cotton C-6424 plants
Authors: Baymuratova Gulbakhar , Nasimov Khasan , Saitkulov Foziljon
Published: May 2023

6-Benzylaminopurine is a broad-spectrum plant growth regulator, able to rejuvenate plants, bring plants out of dormancy, cause the formation of lateral shoots and root shoots, stimulates the formation of chlorophyll and positively affects photosynthesis, making the leaf darker and greener, stronger, in many crops are able, with out-of-root processing of green fruits and berries, to somewhat postpone the ripening time in favor of size and weight. The variety of heterocyclic compounds is due to the possibility of variations: the number and nature of heteroatoms in a molecule, the ring size, the degree of unsaturation, which determines the presence or absence of aromaticity, and the possibility of the existence of condensed structures. The main attention in the methodological development is given to the most common methods of synthesis and the chemical properties of the main classes of aromatic heterocyclic structures. This choice is due to the fact that it is aromatic heterocycles that exhibit specific chemical properties inherent only to these classes of compounds, while the properties of saturated structures or unsaturated non-aromatic heterocycles, as a rule, are similar to their acyclic analogs.

Published: May 2023

The saw gin, the primary technical device used in the cotton ginning process, is responsible for separating the cotton fiber from the cotton seed. After being cleansed of khaschops and dried to the desired humidity in the drying, cleaning, and cleaning shops, seeded cotton is transferred to the main building of the business for ginning (separation of fiber). Up to now, 4DP-130, 5DP-130, and DPZ saw gins have been employed in cotton ginning operations to spin medium fiber seeded cotton. The ginning machine's operation, which separates the fiber from the seed in cotton gins, is largely responsible for the creation of high-quality fiber. Maintaining natural quality indicators during the technical process of first processing of cotton, i.e. the appearance, length, and presence of minute impurities in the fiber, is key to ensuring the competitiveness of cotton fiber produced in our nation on the global market. One of the most crucial processes is the ginning of seeded cotton with the appropriate amount of moisture and dirt, which involves removing the fiber from the seed. The length of the fiber, the impurities in the content, the absence of damage, and the hairiness of the seed all play a significant role in this process.

Published: May 2023

Nowadays, the average person's diet does not contain enough foods that are high in readily absorbed proteins. Using cheaper and healthier vegetable proteins in favor of animal proteins is one option to address this issue. The only crop with high-quality protein is soy. With the exception of methionine and cysteine, soy protein has a good balance of all the necessary amino acids. 15–25% of proteins are found in meat products. There are no other vegetable legumes (beans, peas) with a protein content (44–45%) and oil (20–22%) as high as vegetable soybeans while they are in the green bean phase. This crop is particularly nutrient-dense, and adding vegetable soy to diet enables to add proteins and other essential elements to cuisine. As soy protein is more similar to proteins of animal origin in terms of protein complexity and the presence of key amino acids (lysine, tryptophan, etc.), both animal and human organisms require less energy to transform soy protein into body proteins. The use of soy protein additives in meat products leads to enrichment with proteins and a significant improvement in the functional and technological properties that determine the structural and mechanical characteristics of the combined meat products.

Authors: Gulmurodova Shakhnoza , Sattarova Rano
Published: May 2023

One of the primary crops grown in the Republic of Uzbekistan is cotton. Root rot and gommosis, two cotton sprout diseases, seriously harm cotton cultivation. Some illnesses were shown to have significantly increased in some years. Cotton seeds coated with fungicides are sowed in Uzbekistan. Yet, outbreaks of cotton root rot and blight were frequently seen under production-related circumstances. The gums that protrude from the surface of the cotton plant's damaged organs gave gommosis its name. Many aspects of cotton's growth, including the cotyledons, leaves, stems, bracts, bolls, and fiber, are impacted by gommosis. Among the common diseases that cause significant damage to cotton are diseases of seedlings - this is gommosis and root rot. The article is devoted to the study of the action of preparations: Cruise Extra Cotton 362 g/l, Record 34% against pathogens of cotton seedlings, and iminogommosis and root rot. On the basis of the conducted studies, it was found that the studied preparations have an effective effect on the susceptibility of cotton seedlings to root rot and gommosis. The biological effectiveness of the preparation Record 34% against root rot and gummosis was 86.4% and 93%, and the preparation Cruise Extra Cotton 86.1 and 77%.

Published: May 2023

It is known that two varieties of wheat are grown in Uzbekistan. Common wheat (Triticum aestivum L.) and durum wheat (Triticum durum L.) are cultivated in the main part of wheat fields. Durum wheat varieties included in the State Register in Uzbekistan are mainly spring and duvarak. Considering this feature and the high quality of the grain, the purchase price is 30-50% more expensive than that of common wheat, they fully meet the needs of the ever-growing macaroni-confectionery industry. Durum wheat grain is the main raw material used in the preparation of pasta and pasta products, as well as in the confectionery industry. In this case, high technological quality of durum wheat grain is required. In the next two years, the purchase price of durum and common wheat grain in the world increased significantly. Therefore, expansion of durum wheat cultivation areas in different soil and climate conditions, improvement of agrotechnology of care, obtaining high and quality grain harvest are urgent issues.

Published: May 2023

This paper is aimed to generalize and analyze information about endangered wildlife species in the disturbed fen site (comparing the state of surrounding wetlands) to predict their condition during rehabilitation and restoration of the site and subsequent monitoring during successional processes in the wetland ecosystems. The research was carried out on the territory of the Biosphere Reserve of UNESCO “Nizhegorodskoe Zavolzhye” on the example of the Kamskoe–Osinovye Kotly mire, which is a part of the Ramsar wetlands “Kama-Bakaldino Mires” (Nizhny Novgorod region). The area of the mire is about 15,000 hectares. A part of the mire with a total area of 2,770 hectares was drained and disturbed as a result of peat extraction since the 1970s to 1990s. We carried out surveys of flora and vegetation counts of small mammals, birds, amphibians and reptiles, butterflies and moths in 2021. Also for the analysis we used research data obtained in 1981-2019. A total of 58 endangered wildlife species listed in the Red Data Book of the Nizhny Novgorod region were registered in the studied territory, 14 species of which were discovered here for the first time. The location of the site which are planned to be restored, in the central part of the mire, surrounded by undisturbed communities is a condition for its successful restoration with the full biota after watering. Secondary watering of the site of former peat mining will not cause damage to endangered wildlife species. To maintain biodiversity and conserve the complex of meadow and semi-forest species we recommend carrying out the haymaking in the open spaces adjacent to the mire on the territory of the projected national park. Also we believe the succession processes in the mire and the endangered wildlife species conditions to have to be controlled.

We dealt with the study of the ability of different varieties of cherries, cherries and vegetatively propagated rootstocks to reproduce by green cutting explants in artificial substrates in buildings with a controlled microclimate inside. As varieties in the experiment, such varieties of cherries as Shpanka black, Podbelskaya, Shubinka and Lyubskaya, cherries Revershon, Bakhor, and Drogana yellow were used. Of the vegetatively propagated rootstocks, the following were studied: P-1, P-2, P-3, PN, VTS-13, VP-1, ORP-2, ORP-3, VSL-2 (Krymsky 5), SAV-6R. Of the used cherry varieties, the best rooting of green cuttings was possessed by such cherry varieties as Shpanka black, Podbelskaya and Shubinka, with a quality index of cuttings rooting in the substrate of 70.1 to 83.5%. In sweet cherry varieties, this indicator was 2.5 times lower and generally did not exceed 30.2%. Vegetatively propagated rootstocks provided high quality results of rooting of cuttings explants. In almost all of these rootstocks, the rooting rate of green cuttings did not decrease below 72%. The average rooting rate of rootstock cuttings was 85.7%. This indicates that these rootstocks can be used for industrial cultivation of stone fruit seedlings.

Authors: Zokirov Kurbonalijon
Published: May 2023

Crop growth in arid and semiarid regions usually depends on irrigation, but inappropriate irrigation practice can result in water stress. Water needs of watermelon are the highest during the period of strong formation of vegetative and generative organs. Thus, 85-90% moisture is required from seeds for seed germination. Before the formation of fruit, soil moisture should be maintained at 70% of the total field moisture capacity of the soil, and at the time of fruit ripening at 60%. In this article, the results of experiments based on the development of optimal irrigation regime and fertilization rate for the cultivation of watermelon plants in mulched fields by drip irrigation method, differentiated soil moisture (60...70...60%, 65...75...65%, 70...80...70%, 75...85...75% SAM (SAM - Soil available moisture)), and fertilization rates (without fertilizer, N100P80K40, N120P100K50 and N140P120K60 kg/ha) have been written. Also, the effect of fertilization rates (N100P80K40, N120P100K50 and N140P120K60 kg/ha) on the quality indicators of watermelon fruit, the amount of dry matter, sugar, nitrates and “C” in the fruit has been noted.

Published: May 2023

In most regions of Uzbekistan, the biological productivity of the climate will decrease by 10-20%, and in some regions by 30-40%, the steppe and semi-desert zones will expand further. Therefore, it is impossible to effectively develop irrigated agriculture without the development and implementation of resource and water-saving technologies aimed at increasing the efficiency of irrigated water use. We carried out our experiments based on the development of optimal irrigation norms for the cultivation of watermelon plants in mulched fields by drip irrigation, keeping the differentiated soil moisture (60...70...60%, 65...75...65%, 70…80...70% and 75…85...75% SAM) in the defined norm. In this case, the soil moisture limit before irrigation is 60...65...70...75% SAM according to the experimental options of 0-20 cm layer in the “planting - shatrik” period and 0-40 cm layer in the “shatrik - bloom” period; The 0-50 cm layer was maintained at 70...75...80...85% SAM during the “bloom - fruit formation” period and the 0-50 cm layer at 60...65...70...75% SAM during the “ fruit formation - ripening” period.

Published: May 2023

As vegetable crops are essential for feeding the world's population, significant effort is put into growing environmentally friendly food while also raising production, reducing prices, and improving export potential. In the world, 2.496 million hectares of land are planted with cucumbers, producing 83.8 million tonnes of vegetables yearly. At 65 million tonnes, China is in first place, followed by Iran, Russia, Turkey, and the United States. Vegetable crops are essential for feeding the world's population, which implies their significance in ensuring food security. Additionally, the text mentions that efforts are being made to cultivate ecologically sound produce, increase productivity, and enhance export potential. Results showed that the pest caused a sharp decrease in carbohydrate levels in plant stems and roots, disrupted photosynthesis and metabolism in leaves, and caused changes in leaf shape. Severe damage could result in plant death and reduced yields. The effectiveness of three chemical insecticides, namely Xen pin R, Cruiser, and Viospilan, against aphids was tested. Xen pin R and Cruiser showed high efficacy against aphids, resulting in 94.3-98.2% and 84.4-90.0% yield on the 21st and 14th day, respectively.
Economic efficiency and development of the third domain of reindeer husbandry (in the republic of Sakha)
Authors: Tarasov Mikhail , Val Olesya , Teryutina Marianna
Published: May 2023

As is known, the concept of economic efficiency is one of the important categories characterizing the performance of reindeer herding farms. From the point of view of the theory of economic analysis, there is no unified definition of economic efficiency, which means that, as seems to us, the success of reindeer herding farms is still not determined sufficiently. In the article, we also prove that defining the economic efficiency of reindeer husbandry only by the meat production efficiency is not sufficient because the meat production process is not integrated with the processing of reindeer herding products and its sales. As a result, the economic efficiency of reindeer herding production is severely underestimated and leads to low profitability or even losses. The economic efficiency of production can be determined at the national, branch, enterprise and on-farm subdivision, i.e. there is a multilevel approach to the criteria of efficiency or duality of the criteria of efficiency. It is known that indicators of economic efficiency include cost recovery, net production, profit, profitability, rate of return, productivity of live labour, that is, economic efficiency of production is characterised by the ratio of economic effect to costs, which caused this effect. Analyzing the approaches to assessing the efficiency of reindeer herding farms, we came to the conclusion that an integrated approach should be added to the existing ones, as the meat production process is not integrated with the processing of reindeer herding products and their sales, as a result, the economic efficiency of reindeer herding products is greatly underestimated. However, reindeer breeding farms, which receive essentially ecologically pure meat, do not have special prices for it established by the Government of the Republic of Sakha (Yakutia). The establishment of such prices at the regional level would significantly raise the efficiency of reindeer breeding as a branch of economy as a whole. The main task of reindeer farms in the North-East of Russia, which includes the Republic of Sakha (Yakutia) at the present stage is a high average slaughter meat of reindeer carcasses, equal to 65-90 kg. and higher. This main indicator should not be bypassed or denied by zootechnicians, scientists, and heads of agricultural production. Production of cheap high-quality venison meat. - is the key to success.

Published: May 2023

Studies of the water-physical, physical-chemical and biological properties of meadow-chernozem soils were carried out on a rice irrigation system located in the present-day delta of the Kuban River. Rice meadow-chernozem soils have good water and general physical properties of humus layers. An increase in compaction is observed in the lower horizons of these soils. Meadow-chernozem soils are distinguished by low content of organic matter in arable horizons (3,2-3,4 %), neutral reaction of soil solution (рН 6,8-6,9) and high indices of cation exchange capacity (38,7-39,1 mmol/100g). The mycological composition of the studied soils in the autumn-spring periods was identified and identified. The soil was more saturated with representatives of the suppressive group at the beginning of rice vegetation, the opportunistic group was not detected and the antiphytopathogenic potential was 1:2. The spring-fed rice crop rotations soils are prone to soil stresses that are oversaturated with suppressors. In autumn, the ratio of conditionally suppressive to saprotrophic and pathogenic mycota was 1.5:4.5:7. The growth of colonies of the micromycete genus Trichoderma is traced, which confirms the beginning of a long process and the slow recovery of soil degradation processes.

The economic, social, and ecological wellbeing of a society are all negatively impacted by the traffic congestion issue. Intelligent Transportation Systems (ITS) have been used to better sustainable transportation systems across the globe, helping to lessen the unsustainable effects of the clogged highway issue. The goal may be reached by examining the positive effects ITS deployments have had on urban areas in the United States. In addition to the statewide findings, we also do in-depth research on the economies of seven major Florida communities. A fuzzy-data envelopment analysis (DEA) technique is used instead of the conventional DEA approach for sustainability performance analysis in order to take into account the uncertainty in benefit and cost evaluations. While all of the ITS investments are very successful when looking at the cost-benefit ratio, the findings from the fuzzy-DEA method show that some of them are less efficient than others. This research's TBL findings give a fuller picture of the societal and economic benefits of ITS-related congestion reduction, including its drawbacks, indirect indicators, and environmental advantages. In addition, decision makers had positive findings from TBL analysis of ITS investments and comparisons of sustainability performance of ITS initiatives.

Authors: Kungwola Korawin
Published: May 2023

Aviation in Thailand after the spread of the Covid-19 has drop of 81.7 percent in international and domestic passengers in year 2020.Airlines must develop strategies to get passengers to use their services once more when more people are flying in order to generate revenue. The purpose of this research is to compare the various preventive measures in order to stop the spread of COVID-19implemented by four low-cost airlines in Thailand and how passengers perceive them. Online questionnaires were used to collect the quantitative data of 400 sample groups. The findings revealed the perception of the passengers that all four low-cost airlines had the same protective measures in place to stop the spread of the 2019 Coronavirus Disease (COVID-19) including measures to prepare the aircraft, screen passengers, manage passenger density, and prepare for emergencies. However, these low-cost airlines employ a variety of preventative measures, such as hygiene regulations for on-board service employees, Service precautions before to boarding, Cabin service measure and passenger hygiene measure. The Civil Aviation Authority of Thailand can use the study's findings to help create regulations and standards for safeguarding the safety of passengers in critical epidemic conditions like the coronavirus pandemic (Covid-19).

Authors: Shageeva G.R.
Published: May 2023

The article discusses the features of reducing the negative impact of technogenic factors in the implementation of logistics operations in the light of the Concept of Sustainable Development. According to the author, the logistics sector plays an important role in the economic development of the country. However, its activities can negatively affect the quality of the environment, during the implementation of logistics operations there is a significant consumption of energy of various nature, in the process of which there is a threat of environmental pollution. Efficient logistics largely contributes to the success of the business due to fast deliveries with minimal time and money. Logistics is the process of obtaining materials, products and services where and when they are needed. When considering the concept of sustainable logistics, it is important to take into account three aspects of sustainability: economic, social and environmental. Sustainable logistics is not only environmental friendliness and harmlessness to the environment, but also the impact on production processes, starting from where the raw materials are extracted, the processes involved, the use and possible processing of the product or service. When analyzing the problem of evaluating the effectiveness of logistics operations, one of the evaluation criteria will be sustainability. Sustainable development involves coordination between the environment and the economy to achieve social, economic and environmental sustainability.

Published: May 2023

The object of the research in this article is the transport infrastructure of the regions that are part of the Arctic zone of the Russian Federation. The authors aim to study the main socioeconomic problems that exist in the region due to the underdevelopment of transport infrastructure, as well as ways to solve them. To fulfil their research objectives, the authors used a comparative analysis method, a correlation analysis method, and a legal analysis. The study identified the specifics of the construction of transport infrastructure in the far north regions. The length of the road and rail network in the Arctic has been analysed compared with the regions of Central Russia, and the factors that limit the development of transport infrastructure have been identified. The strong dependence of freight traffic volumes on population size was revealed using the example of the Murmansk Oblast, and the main problems affecting the demographic situation in the region were identified. The problem of low passenger flow in air transportation was considered. The authors suggested the following ways of solving the problems: increasing the number of contracts PPP in their classic form, reducing the number of concession agreements, creating a transport system project based on the example of the US Interstate Highway System in the Russian Arctic, drafting a unified transport budget for all territories that make up the Arctic zone, creating a single executive authority for the Arctic zone to distribute the budget evenly.
