Macro- and Microelement Variability in Soil-Plant Systems Across Vertical and Horizontal Zonation Gradients: A Comprehensive Literature Review
type: item
description: Section: Articles Keywords: macroelements, microelements, vertical zonality, horizontal zonality, biogeochemical cycling, spatial variability, bioaccumulation, soil properties, agroecosystems This article provides a comprehensive analysis, based on literature, of the distribution, bioaccumulation, and biogeochemical cycling patterns of macro- and microelements in the soil–plant system under conditions of vertical (altitudinal) and horizontal (landscape-geographical) zonality. The aim of the study is to identify and generalize the main factors influencing the dynamics of elements under different soil-climatic conditions. In the research, sources indexed in international scientific databases were selected and studied using qualitative and comparative analysis methods. The results showed that the distribution of macro- and microelements is closely related to the physical and chemical properties of the soil, climatic factors, biological characteristics of plants, and anthropogenic impacts. Vertical zonality determines the cycling of elements governed by climate, while horizontal zonality forms spatial heterogeneity through landscape and soil diversity. At the same time, the soil–plant–microbiome interaction acts as an important regulator in the assimilation and migration of elements. The research results demonstrate the necessity of evaluating macro- and microelement dynamics based on an integrative approach and have significant scientific and practical importance in the formation of sustainable agroecosystems.

title: Influence of Soil Agro-Physical Properties and Irrigation Regimes on Yield and Productivity of Repeated Sunflower (Helianthus annuus L.) Varieties and Hybrids under Arid Conditions of the Bukhara Region
description: Section: Articles Keywords: sunflower, repeated crop, soil agro-physical properties, irrigation regime, soil density, moisture capacity, yield, Bukhara region This scientific study is devoted to determining the effect of soil agro-physical properties and irrigation regimes on the yield of sunflower varieties and hybrids cultivated as a repeated crop under irrigated farming conditions in Bukhara region. During the research, the main agro-physical indicators of the soil, such as bulk density, moisture capacity, and water-air regime, were studied under different irrigation variants. The results of field experiments and laboratory analyses confirmed that irrigation rates and timing have a significant effect on soil condition as well as plant growth and development. It was found that under an optimal irrigation regime, the agro-physical condition of the soil improved, the physiological processes of plants became more active, and the formation of yield components occurred at a high level. Insufficient and poorly justified irrigation regimes, however, were observed to reduce yield due to soil compaction and moisture deficiency. The obtained scientific results have important scientific and practical significance for optimizing the technology of sunflower cultivation as a repeated crop, ensuring the rational use of water resources, and achieving stable and high yields.

Modeling Optimal Fertilizer Application and Evaluating Soil Fertility and Crop Productivity in Saline Soils under Advanced Agrotechnologies
type: item
description: Section: Articles Keywords: saline soil, wheat yield, mineral fertilizers, optimal fertilizer rate, agrotechnology, soil fertility, Surkhandarya, Bukhara, modeling, irrigated lands This study is aimed at scientifically substantiating an optimal fertilizer application system to increase wheat yield under saline irrigated soil conditions of the Surkhandarya and Bukhara regions of Uzbekistan. Field experiments were conducted during 2023–2025 on moderately saline soils (EC 4.5-6.8 dS/m), where the effects of different mineral fertilizer treatments (NPK) on crop productivity were evaluated. The results demonstrated that the application of mineral fertilizers significantly increased grain yield compared to the control treatment. The optimal rate (N₁₈₀P₁₂₀K₉₀ kg/ha) provided the highest agrobiological and economic efficiency in both regions, increasing wheat yield by more than 60% in Surkhandarya and by 65–70% in Bukhara. Increasing fertilizer rates beyond the optimal level did not result in a statistically significant yield improvement. Regression analysis revealed that yield decreased with increasing soil salinity; however, this negative effect was partially mitigated under optimal fertilization regimes. The findings highlight the importance of determining optimal fertilizer application ranges in saline soils to ensure efficient resource use and stable crop productivity.

description: Section: Articles Keywords: Acinetobacter baumannii, Enterobacter cloacae, Klebsiella pneumoniae, Momordica charantia seed extract, Staphylococcus aureus Momordica charantia (bitter gourd) has long been used in traditional medicine and possesses multiple bioactive phytochemicals with potential antimicrobial properties. This study was aimed to evaluate the antibacterial activity of Momordica charantia seed extracts against selected Gram-positive and Gram-negative bacterial pathogens using the Kirby–Bauer disc diffusion method. Seed extracts of M. charantia were prepared and tested against Gram-positive bacteria and Gram-negative bacteria at a concentration range of 100-800 mg/mL. The strongest inhibition among Gram-positive bacteria was observed against Listeria monocytogenes at all concentrations and highest at 700 mg/mL, whereas for Staphylococcus aureus, inhibition was between 600-700 mg/mL with highest at 700 mg/mL. However, for Bacillus cereus the inhibition was observed between 500-800 mg/mL. As for Gram negative bacteria, inhibitory activity was observed against Acinetobacter baumannii from 700-800 mg/mL and Enterobacter cloacae at 800 mg/mL. No significant antibacterial activity was observed against Streptococcus mutans, Klebsiella pneumoniae, or Salmonella enteritidis. Momordica charantia seed extract possesses selective antibacterial activity against several clinically relevant microorganisms, particularly Gram-positive bacteria and certain multidrug-resistant Gram-negative pathogens. These findings support the medicinal value of M. charantia seeds and highlight its potential as a source of novel antibacterial compound.

The Impact of Different Irrigation Regimes on the Yield of Winter Wheat and Leguminous Crops and on Soil Condition in the Bukhara Region
type: item
description: Section: Articles Keywords: Irrigation regimes, winter wheat, leguminous crops, crop rotation, yield, water use efficiency, soil agrophysical condition, reclamation (meliorative) condition This article examines the impact of different irrigation regimes on the yield of winter wheat and leguminous crops, as well as on the agrophysical and reclamation (meliorative) condition of soils under irrigated farming conditions of the Bukhara region. The research was conducted through field and laboratory experiments, in which crop productivity and soil parameters were evaluated under low, moderate, and optimal irrigation regimes. The results obtained indicate that an increase in irrigation rate led to a consistent rise in winter wheat grain yield. The inclusion of leguminous crops in crop rotation significantly increased yields under all irrigation regimes and contributed to improving the soil nutrient regime and physical condition. Under optimal irrigation conditions, soil moisture retention capacity increased, while bulk density and the content of soluble salts decreased. The findings demonstrate that the integrated application of appropriate irrigation regimes and crop rotation in the cultivation of winter wheat and leguminous crops is a scientifically grounded solution for achieving high agronomic efficiency, rational use of water resources, and preservation of soil fertility. These conclusions are of practical importance for the development of sustainable and resource-efficient agricultural systems in the Bukhara region.

Impact of Soil Salinization and Groundwater Levelson Vegetation Cover in Irrigated Agroecosystems: An Analysis Based on GIS and Vegetation Indices
type: item
description: Section: Articles Keywords: soil salinization, groundwater level, vegetation cover, GIS, vegetation indices, Syrdarya region This study is devoted to analyzing the impact of soil salinization and groundwater levels on vegetation cover in irrigated agroecosystems using GIS technologies and vegetation indices. The research employed multispectral satellite imagery from Landsat 8–9 and Sentinel-2, data on soil salinity and groundwater levels, as well as the NDVI and SAVI vegetation indices. Spatial analysis was conducted in a GIS environment using IDW and Kriging interpolation methods, Moran’s I spatial autocorrelation index, spatio-temporal regression, and time-lag techniques. The results showed that areas with high groundwater levels tend to exhibit increased soil salinity, which in turn leads to a deterioration of vegetation cover. It was also determined that changes in groundwater levels affect soil salinity and vegetation indicators with an average delay of approximately 3–4 months. Spatio-temporal monitoring based on GIS and vegetation indices serves as an important analytical tool for the scientific planning of land reclamation measures in irrigated agroecosystems, promoting the rational use of resources and ensuring the sustainability of agroecosystems.

Biogeochemistry of Sandy Desert Soils in the Bukhara Oasis and the Sparse-Leaved Yantok (Alhagi sparsifolia) Plant (A Case Study of Shofirkon District)
type: item
description: Section: Articles Keywords: macroelements, bioaccumulation, sandy desert soils, biogeochemical processes, element migration, bioindicator plants This study investigated the distribution characteristics of macroelements (Na, K, Ca) in the stem, leaves, and seeds of the sparse-leaved yantok (Alhagi sparsifolia) plant growing in sandy desert soils. The research findings revealed the selective accumulation of elements within plant tissues and identified potassium as the dominant element accumulated across all organs. In particular, the high concentration of potassium in generative organs is explained by the plant’s metabolic activity and reproductive stability. The predominant accumulation of sodium in the leaves indicates the presence of an adaptive mechanism that maintains osmotic balance through the deposition of ions in vegetative tissues. The relatively low calcium content is associated with its limited bioavailability in sandy soils. The bioaccumulation of the studied elements followed the sequence K > Na > Ca, reflecting the selective mineral nutrition strategy of the sparse-leaved yantok adapted to arid environments. The obtained results suggest that this plant can serve as an important bioindicator for assessing macroelement migration in desert ecosystems and provide a scientific basis for a deeper understanding of biogeochemical processes within the soil–plant system.

The Role of Amino Acids in Soil
type: item
description: Section: Articles Keywords: Amino acids, soil fertility, humus, sierozem soils, irrigation, nitrogen compounds, soil biochemistry, Fergana Valley, soil organic matter, dehumification, soil energy potential The study investigates the composition, distribution, and functional role of amino acids in the soils of northern Fergana, focusing on virgin and irrigated sierozems. Using a combination of genetic–geographical, geochemical, and morphogenetic research methods, the study analyzes the humus condition, nutrient composition, and energy potential of soil organic matter. Results show that despite their relatively small proportion in total soil nitrogen, amino acids play a critical role in plant nutrition and soil fertility by acting as bioactive compounds that regulate physiological processes such as chlorophyll synthesis, osmotic regulation, and stress tolerance. The research reveals that irrigation significantly affects the qualitative and quantitative composition of soil amino acids, leading to decreased humus content and transformation of nitrogen-containing compounds. In both virgin and irrigated sierozems, 14–20 amino acids were identified, with variations across soil horizons. The findings emphasize the energetic and biochemical importance of amino acids in maintaining soil fertility and highlight the need for further research on soil dehumification and fertility restoration.

Climate Change and its Impact on Southern Fergana Landscapes
type: item
description: Section: Articles Keywords: climate change, Fergana Valley, agroclimatic trends, temperature anomalies, agricultural adaptation, water resources This study examines the impacts of climate change on the Southern Fergana landscapes, focusing on temperature trends, precipitation variability, and their implications for agricultural productivity in Uzbekistan. Utilizing meteorological data from the Kokand weather station (1930–2023), the research analyzes long-term shifts in seasonal temperatures, agroclimatic parameters, and extreme weather events. Key findings reveal a significant temperature increase, with winter temperatures rising by 0.8°C between 1960–1990 and summer anomalies becoming more frequent. Precipitation patterns show irregularity, with April experiencing excessive rainfall that disrupts crop sowing cycles. The study highlights the adverse effects of rising temperatures on staple crops such as cotton, wheat, and tomatoes, with yield reductions of 9–22% under prolonged heatwaves (>35°C). Conversely, elevated CO₂ concentrations and traditional practices like winter irrigation ("chilla suvi") demonstrate partial mitigation benefits, improving soil moisture and reducing pest infestations. Regional disparities are evident: northern areas with shallow groundwater face challenges in fruit cultivation, while southern regions adapt through diversified horticulture. Projections indicate worsening conditions by 2070–2100, with intensified water scarcity threatening irrigated lands. The findings underscore the urgency for adaptive strategies, including optimized irrigation scheduling, heat-resistant crop varieties, and policy reforms to address food security. This research provides critical insights for sustainable agricultural planning in Central Asia’s arid zones under evolving climatic stresses.

Genesis and Migration of Salts in Irrigated Meadow Sazovs Soils
type: item
description: Section: Articles Keywords: sulfate, carbonate, phosphate, chloride, meadow sazovs soil The study focuses on the Central Fergana region, which is characterized by an arid climate and low natural drainage capacity. It has been observed that even the salts accumulating at a slow rate in such soils eventually reach significant concentrations. In irrigated lands, an additional 1–1.5 g of salts per liter of irrigation water is continuously introduced, leading to an increased accumulation of soluble salts both quantitatively and qualitatively. Furthermore, it has been noted that mineralized groundwater located close to the surface also contributes to this process.
