Coleoptera, commonly known as beetles, represent the largest order of insects, with over 350,000 described species occupying diverse ecosystems worldwide. Their ecological roles are crucial for maintaining environmental balance, as they function as herbivores, predators, decomposers, and pollinators. This article explores the habitat diversity of beetles, their feeding ecology, reproductive strategies, and interactions within ecosystems. Additionally, it examines the adaptive mechanisms that enable Coleoptera to thrive in various environmental conditions. Human activities, including habitat destruction, climate change, and pollution, significantly impact beetle populations, raising concerns about biodiversity conservation. Understanding the ecological significance of Coleoptera is essential for assessing ecosystem health and developing effective conservation strategies.  

The article presents the main soil types in the region and their distribution by mechanical composition. It also presents methods for determining the mechanical composition of the region's soils and the results of the analysis of the mechanical composition of the soil by fractionation.  

This article presents mathematical analysis data on the correlations between root weight and several characteristics in simple and complex F3 sunflower hybrid families, including single plant productivity, plant height, basket diameter, and total leaf area. In this case, the correlation relationships in highly heterozygous hybrids changed in a positive direction, and the high indicators of two-three traits were concentrated in one genotype.  

Kiwifruit (Actinidia spp.) is a highly nutritious fruit valued for its rich content of vitamins, antioxidants, and minerals, particularly calcium, which plays a crucial role in its physiological processes. Calcium influences several aspects of kiwifruit growth, quality, and shelf-life, yet the optimal strategies to manipulate its levels remain under exploration. This paper reviews agronomic strategies aimed at increasing kiwifruit calcium content, including soil amendments, foliar applications, rootstock selection, and the use of controlled environments. Through a detailed analysis of these strategies, we aim to better understand the relationship between calcium content and fruit physiology, including its impact on fruit firmness, ripening, and resistance to physiological disorders. The findings suggest that while calcium plays a key role in kiwifruit quality, effective agronomic interventions are essential for optimizing its levels and improving overall fruit production. Future research in this area will provide valuable insights for advancing sustainable and high-quality kiwifruit production.  

Currently, in a period of expected climate change, specific soil conditions are observed in every part of our country. In restoring the soil structure, various chemical elements in the soil, their structure, mechanical composition, satisfaction of water demand, as well as the application of organic and mineral fertilizers to the soil and its water-holding capacity are of great importance. The main task of today is to analyze the data obtained from the analysis of the formation of soil structure depending on physicochemical factors - the amount of precipitation, the amount of water and its porosity, the type of soil, and its mechanical composition.  

This article provides an in-depth analysis of the cultivation technology of Silybum marianum Gaertn. L. (Milk Thistle), a medicinal plant valued for its hepatoprotective properties, primarily attributed to its bioactive compound, silymarin. The article explores essential aspects of milk thistle cultivation, including soil and climate requirements, sowing practices, fertilization, irrigation, pest and disease management, as well as harvesting and post-harvest processing. Additionally, it highlights modern biotechnological advances, such as in vitro and hairy root culture techniques, that can complement traditional farming methods to enhance the production of silymarin. Practical examples are provided to illustrate the recommendations for successful cultivation, making it a comprehensive guide for both small-scale and large-scale producers.  

Halophyte plants, which thrive in saline environments, offer sustainable solutions to soil salinization, water scarcity, and climate change. This article examines their benefits, cultivation techniques, economic significance, and challenges. Halophytes contribute to soil reclamation, biofuel production, and food security while also holding commercial potential in pharmaceuticals, cosmetics, and renewable energy. However, limited awareness, high costs, and market barriers hinder large-scale adoption. Advancements in science, biotechnology, and policy support could integrate halophytes into modern agriculture, promoting economic growth, ecological restoration, and sustainable resource management.  

This study investigates halophytic plants of the genus Salsola L., which are widely spread in the southern part of the Aralkum Desert. During the research, a PCR product of approximately 1200 bp associated with the DREB2A gene was amplified in one of the species, Salsola richteri. This gene plays a key role in plant adaptation to drought and salt stress. The obtained data will be used for sequencing the DREB2A gene and analyzing its expression.
