Seasonal Dynamics of Collembola (Springtail) Fauna in the Soils of Fruit Orchards National University of Uzbekistan
type: item
description: This article investigates the seasonal dynamics of Collembola fauna in the soils of fruit orchards. During the study, seasonal changes in the abundance, activity, and species composition of collembolans were analyzed throughout the year. Soil samples were collected in spring, summer, autumn, and winter, and collembolans were extracted using a Berlese–Tullgren apparatus and identified based on morphological characteristics. The results showed that the highest population densities of collembolans were recorded in spring and summer, which can be explained by favorable soil moisture and temperature conditions during these seasons. In autumn, their abundance decreased relatively, while in winter it reached minimum levels. The findings confirm that collembolans are important bioindicators for assessing soil ecological conditions. The obtained data are of scientific and practical significance for monitoring soil health, ensuring ecological sustainability, and conserving biological diversity in fruit orchard agroecosystems

Effects Of Chitosan And Whey Powder Supplementation On Mineral Metabolism And Digestive Enzyme Activity In Broiler Chicks: Evidence Synthesis And A Methodological Framework
type: item
description: Improving feed efficiency while reducing reliance on antibiotic growth promoters remains a key challenge in modern broiler production. This paper synthesizes international and CIS literature on chitosan (a cationic biopolymer) and whey powder (a dairy by-product rich in high‑biological‑value proteins and bioactive peptides), focusing on two mechanistic endpoints: mineral metabolism (Ca, P, Mg) and digestive enzyme activity (amylase, lipase, protease). Using a scoping‑review approach, studies published between 2010 and 2026 were mapped across PubMed, Cambridge Core, MDPI, Google Scholar, and open regional databases. Data were extracted on dosage, duration, measurement protocols, and key zootechnical outcomes. The synthesis indicates that chitosan may modulate intestinal barrier integrity, microbiota balance, and mineral bioavailability through adsorption and ion‑exchange properties, whereas whey powder may support metabolic stability via high‑quality protein fractions and peptides, with downstream effects on gut morphology and nutrient utilization. Local studies from Uzbekistan report beneficial shifts in growth performance, mineral indicators, and bone‑related metrics when chitosan and whey are applied in combination. The paper proposes an evidence matrix, a conceptual mechanism model, and practical methodological recommendations for future controlled trials.

Cultivation of Cotton Using Drip Irrigation Technology
type: item
description: The article presents the results of an experiment conducted on meadow-alluvial soils of the Bukhara region, where the groundwater table is at a depth of 2.0–2.5 m. In the experimental cotton field irrigated using drip irrigation, when the pre-irrigation soil moisture was maintained at 75–80–65% of the field capacity (FC), the cotton was irrigated four times according to the 0-4-0 irrigation scheme. No irrigation was applied during the period from germination to flowering, while during the flowering–boll formation stages, four irrigations were carried out with irrigation rates ranging from 616 to 651 m³/ha. The total seasonal irrigation norm amounted to 2521–2537 m³/ha, which is 1594–1633 m³/ha less compared to the control variant, indicating significant water savings

The Impact Of Biochemical And Hematological Blood Parameters On Aerobic Oxygen Delivery Capacity In Young Athletes
type: item
description: This study investigated the relationship between hematological and biochemical blood parameters and aerobic capacity in young male and female athletes. The findings revealed a significant correlation between red blood cell parameters (RBC, hemoglobin [HGB], and hematocrit [HCT]) and key indicators of aerobic capacity, including VO2max, anaerobic threshold (AP), and oxygen utilization efficiency (VO2/YYQ). Additionally, it was observed that lower levels of urea, total bilirubin, and iron in the blood were associated with a higher heart rate at the anaerobic metabolism threshold. The study underscores the importance of monitoring hematological and biochemical parameters to better understand and enhance athletic performance in young athletes, while also highlighting the need for genderspecific approaches in training and physiological assessment

The Influence Of Different Doses Of Mineral Fertilizers On The Content Of Digestable Forms Of Nitrogen And Phosphorus In Meadow Gray Soil And The Productivity Of Winter Wheat In Irrigged Uzbekistan
type: item
description: In the diverse soil and climatic conditions of irrigated agriculture in Uzbekistan, in connection with global climate change and soil degradation, improved technologies for the use of mineral fertilizers have been developed and are an urgent task. In addition, at present, in almost all zones of irrigated agriculture of the republic, mineral fertilizers are applied to winter wheat according to the Agro recommendations prepared earlier [1;31-33, 2;37-41, 3;35]. To obtain guaranteed and planned yields of winter wheat, it is necessary to conduct zonal experiments to study the responsiveness of winter wheat to mineral fertilizers, in particular in the meadow gray soils of the Navoi region

Hydraulic Justification Of Parameters Of Water-Saving Techniques And Technologies For Irrigation Of Agricultural Crops
type: item
description: This study investigates the hydraulic justification of parameters for water-saving irrigation techniques and technologies applied in agricultural crop cultivation. The efficiency of modern drip and sprinkler irrigation systems is analyzed in terms of water conservation, hydraulic performance, and energy consumption. Hydraulic calculations were carried out using Bernoulli’s equation and Darcy–Weisbach formula to determine flow rates, pressure distribution, and head losses within irrigation networks. Field experiments were conducted on cotton, vegetable, and orchard crops under different irrigation technologies. Results demonstrated that drip irrigation reduced water losses to 10–15%, compared to 35–40% in traditional surface irrigation. Sprinkler irrigation saved up to 25–30% of water while ensuring uniform distribution. Energy consumption was reduced by 18–22% when pipe diameters and operating pressure were optimized. On average, 1000–1200 m³ of water per hectare was saved in cotton production. Additionally, water-saving technologies decreased groundwater table rise by 20–25%, reducing soil salinization risks and improving land reclamation conditions. The findings highlight the potential of water-saving technologies as an effective strategy for sustainable water resource management in irrigated agriculture

title: Assessment Of The Biological Efficiency Of The Microbiological Preparation Cropguard (Ipl Biologicals Limited, India) Against Thrips On Cotton Under The Conditions Of Syrdarya Region, Republic Of Uzbekistan
description: The article presents the results of field experiments conducted in 2025 in the Syrdarya region, aimed at evaluating the biological efficiency of the microbiological preparation CropGuard (IPL Biologicals Limited, India), containing entomopathogenic fungi Beauveria bassiana and Verticillium lecanii, against thrips (Thripidae) on cotton. As a reference standard, the biopreparation BioSleep BW based on the entomopathogenic fungus Beauveria bassiana (strain OPB-43) was used. The experiments accounted for the abundance of two thrips species: onion thrips (Thrips tabaci Lind.) and wheat thrips (Thrips angusticeps Uzel). The results showed that at an application rate of 3.0 L/ha, CropGuard reduced thrips density by 87.4%, which is comparable to the reference (84.1%). At a rate of 2.5 L/ha, the efficiency was 82.6%. No phytotoxicity or negative effects on beneficial entomophages were observed
