Various quality indicators of Zagatala 420 corn seeds were studied in 4 plots. Zagatala 420 is a high-yielding corn variety cultivated in Azerbaijan. The study was conducted at the Zagatala Regional Experimental Station of the Research Institute of Agriculture. Temperature stress in corn seeds reduces the ability to germinate. The results show that the germination and physical characteristics of Zagatala 420 corn seeds significantly affect the yield. The effect of various soil conditions on corn seed germination and plant development rate was studied. It was found that the use of fertilizers accelerates the germination of corn seeds. This variety is recommended for cultivation in various agro-ecological regions of the country. The results of the study show that Zagatala 420 is resistant to diseases and pests when using an integrated plant protection system. Flat-shaped seeds develop better in the field than seeds of other shapes.

According to the article, grasslands amount for 103,816 hectares out of 5,502.78 km2 total area of Nakhchivan AR. The grasslands play a vital role in the development of livestock, especially rearing of bovine animals, small-horned livestock and beekeeping. Descriptive research work has been conducted in the field, in order to determine the role of grasslands in the development of livestock farming. There is a strong need for conducting study of the area on the basis of landscape planning. As a consequence of a series of natural and anthropogenic factors, a number of environmental issues have arisen on grasslands, and as a result, some areas have become unusable. 58,020 hectares or more than 50% of grasslands became unusable. On the other hand, 45,796 hectares are in good condition. It should be outlined that since destructive factors outpower restorative factors, there is a risk of losing grasslands in the future. It is about time to seriously engage in the solution of environmental problems related to grasslands. Otherwise, we will face bitter consequences. Therefore, landscape planning should be applied in every research work. Hierarchical landscape composition of the area and the problems in each composition should be clearly defined, and the solutions should be developed accordingly. Research work is notably topical in this context.

Alternative analysis: the prime numbers theory and an extension of the real numbers set
Статья научная
Here we consider the theory of prime numbers at a new methodology. The theory of prime numbers is one of the most ancient mathematical branches. We found an estimate of the all prime numbers sum using the notions of infinite lager numbers and infinitely small numbers, farther we estimated the value of the maximal prime number. We proved that Hardy-Littlewood Hypothesis has the positive decision too. The infinite small numbers define a new methodology of the well-known function o(x) application. We use the sets of the theory of prime numbers and infinitely small numbers with a linear function to formulate the alternative extension of the real numbers set.

Amelioration State of Soils at the Mouth of the Kur River
Статья научная
The analysis of the melioration state of soils at the mouth of the Kura River in the Salyan district was carried out in 2019-2024. The territory is mainly covered with gray-brown, gray, gray-meadow, meadow and meadow-marsh soils. In all areas of cotton and grain crop cultivation, the soils are saline and solonchakous to varying degrees, crusted, swamped, etc. Regardless of the depth of groundwater, there are various types of salinization depending on the agrochemical composition of the soils. In the territory through which the Kura River flows, there is an inappropriate use of its waters, discharge of industrial and domestic wastewater into the river. This is manifested to a greater extent at the mouth of the Kura River, causing floods that pose a threat to the population living here, and creating environmental problems in the marine area. A detailed study of environmental violations at the mouth of the Kura River is relevant. The existing hydrological condition has been analyzed, the causes of melioration problems have been determined, and recommendations have been proposed. The results obtained serve the development of sustainable agriculture and long-term conservation of soil resources in the region.

The study of the process of migration in aphids has great practical importance. Thus, the aphids pass from one plant to another by these morphs and feed there and maintain their population by growing. The literature information on the research of the photoperiodic reactions in aphids is sufficient. However, the seasonal adaptation characteristics of sugar beet aphids have not been studied up to date in Azerbaijan. For this reason, the study of an impact of photoperiod on the emergence of winged ones in the population of black bean aphid is one of the important issues. During the study of reaction of individuals fed in the same routine against the photoperiod in the next generations, it has been defined that short photoperiod is more observed in the following generations. It seems that the information collected from the former generations is directly passed to the next generations. The results show that the continuous breeding of these species by means of parthenogenesis is only available in the long day (14, 16, 18, 24 hours) routine. However, the winged individuals prevail in the short photoperiods. The preference of winged individuals in 24 hours of photoperiod rather than others (14-18 hours) is probably related to the physiological changes occurs in them.

This article investigates the application of digital methods to literary texts, focusing on a comparative analysis of Chingiz Aitmatov's work Samanchynyn zholu (Mother Earth) and its English translation. Recognizing the growing importance of digital humanities in advancing textual research, the aim of this article is to assess the translation's quality and explore the efficacy of Voyant Tools for analyzing texts in the Kyrgyz language, marking one of the first such attempts. Comparative analysis and Voyant Tools' functionalities, including word frequency calculation, collocation identification, and visualization (word clouds, graphs, concordances), the study processed both the 27,161-word Kyrgyz original and the 38,737-word English translation. Key findings reveal thematic alignment between the two texts; characters like Aliman and Tolgonai, and themes such as "Mother Earth," war, and daily life, consistently emerged as central. Despite linguistic structural differences, the translation effectively conveyed the core narrative and character prominence. While minor variations in lemmatization across languages were observed, Voyant Tools successfully provided quantitative and qualitative insights into textual characteristics and semantic preservation. This research demonstrates the robust potential of digital tools to complement traditional literary scholarship, offering a data-driven approach to understanding translation fidelity and enriching the study of Kyrgyz literature.

Analysis of methods limiting gas breakthroughs into production wells at the Fedorovskoye field
Статья научная
The article explores the reasons causing gas breakthrough from the gas cap into the producing wells and oil penetration into the gas-saturated part of the formation at the Fedorovskoe Field. It appears that gas breakthrough to the perforated intervals of producing wells are mainly caused by the geological structure of AS4-8 formations (absence of robust shale break/screen) and relatively small distances from the upper filter holes to the gas- and gas-and-oil-saturated portion of the formation. Two operation modes applicable for this field are described: for the wells intersecting the formation with horizontal shaft under impermeable shale break between gas-and-oil-saturated layers (cases of gas breakthrough are excluded) and for horizontal and vertical wells in the contact zones of gas-and-oil reservoirs or areas with thin split shale breaks (there is continuous gas breakthrough). The article describes engineering solutions ensuring insulation of gas breakthrough into wells...
