The Degree Of Susceptibility Of Soils To Secondary Salinity (Buz district, Andijan province)
No full textThe article analyzes the results of determining the level of salinization of irrigated agricultural land and creating cartograms in the Boz district of the Andijan region, which is part of the territory of Central Fergana. When determining the level of salinity, taking into account the location of the object of study of the area, the chemistry of salinity, the secondary level of soil salinity are determined and recommendations are given on the rate, duration and number of salt flushe
Amino Acids Composition In Irrigated And Typical Grey Soils
No full textIn our republic, large-scale theoretical and practical research is being carried out on restoring and preserving the fertility of protected, fallow and irrigated soils, improving soil processes, and achieving certain results. The Strategy for the Development of Agriculture of the Republic of Uzbekistan for 2020- 2030 states that "... Of the 20.2 million hectares of land intended for agriculture, only 20.7 percent are irrigated lands. Over the past 15 years, the area of irrigated land per capita has decreased by 24 percent (from 0.23 to 0.16 ha), rational use of natural resources, including rational use of land and water resources, forest resources, and improvement of the environmental protection system" are identified as important strategic tasks 1 . Based on these tasks, it is important to determine the current ecological and reclamation status of irrigated lands, apply resource-saving agrotechnologies aimed at improving their humus content and biological activity, compile maps of soil salinity and biological activity of the soil, and implement agrotechnical measures based on this
Microbiological Indication Of Differently Salinated Soils In Termiz District
No full textMicrobiology studies microorganisms that are very small, invisible to the naked eye, and visible only with the help of optical instruments - light or electron microscopes. Microbiology is a science that studies the morphology, physiology, biochemistry, genetics, ecology and systematics of microscopic fungi, bacteria, mycoplasmas, viruses, actinomycetes and microscopic algae. Microbiology is a relatively young branch of biology, which is growing and developing every day. The modern science of soil diagnostics uses the achievements of such sections of soil science as soil morphology, soil chemistry, soil physics and mineralogy. To characterize the soil and its condition, it is closely related to biochemistry, molecular biology, biotechnology, agrochemistry, phytopathology, agriculture, industry, geology, genetics and other sciences. The world of microorganisms is incredibly rich and diverse
Agrophysical properties of soil
No full textIN The article presents analytical data on irrigated meadow-marsh soils; the first watering is carried out before the plant blooms (based on a soil layer of 0-50 cm) at the rate of 700-750 m3 / ha of water; in the early stages of the cotton growth period, the layer should not exceed 0-70 cm, and the watering rate is 850-900 m3 / h
The Effect Of Irrigation On The Yield Of Winter Wheat Varieties
No full textThis research work presents an analysis of the formation of winter wheat yield depending on irrigation methods and irrigation regimes in the cultivation of winter wheat varieties in the conditions of irrigated light gray soils of the Kashkadarya region. According to the average 3-year results obtained during 2022-2024, the yield of winter wheat varieties ranged from 44.3 c/ha to 74.0 c/ha, and it was established that the yield of winter wheat varieties was higher when irrigating with sprinkler irrigation, with an irrigation regime of 70-75-65% of LFC before irrigatio
Method For Determining The Population Dynamics Of Micromammalia In The Southern Aral Sea Region
No full textThe article presents a method for determining the population dynamics of small mammals in the Southern Aral Sea region. Relative calculations of the number of small mammals were carried out using a Gero type recorder, using the trap-line method. To prove the quantitative influence of anthropogenic pollutants on the structure and dynamics of the Microtus Ilaeus population of the studied small mammals, mathematical models were constructed that calculate the coefficient of determination (R2), indicating the degree of influence of each selected factor
The Ecological Balance Of Pathogenic And Beneficial Microflora In The Potato Root System
No full textThis article investigates the ecological balance between pathogenic and beneficial microorganisms in the potato (Solanum tuberosum L.) root system. Based on literature analysis and experimental observations, the interactions between root-associated pathogens and beneficial fungi and bacteria are examined, highlighting their influence on plant health, disease suppression, and productivity. The study demonstrates that maintaining microbial equilibrium is essential for sustainable agriculture, improving crop resistance, and optimizing potato yield. These findings are of high scientific and practical significance for integrated crop management and microbial ecology studies
Bioecological Properties And Agrotechnology Of The Medicinal Plant Convallaria Majalis L. In The Territory Of Karakalpakstan
No full textThe article considers the importance of crop rotation in the cultivation of medicinal plants. It is shown that the crop rotation system has a positive effect on the growth and development of plants. Information is provided on the cultivation technology of the marigold plant. The length of the plant is 8-10 cm, width is 0.5-0.7 cm, and the soil substrate (filled with sand and leaf humus in a 1:1 ratio) is transferred to boxes to a depth of 4-6 cm. The distance between the plants is 4 cm, the distance between the rows is 15- 20 cm, and they are planted in moist soil, then watered. The rhizomes planted in autumn are strong, and their vegetative development is faster than in spring. It is advisable to place 20 plants per 1 m of land
The Impact Of Biochemical And Hematological Blood Parameters On Aerobic Oxygen Delivery Capacity In Young Athletes
No full textThis 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 assessmen
Sweet Pepper Pests And Chemical Control Measures Against Them
No full textThis article presents the morphology and bioecology of the main pests of sweet pepper, spider mites, and greenhouse thrips. A chemical method of control against greenhouse thrips was used, in which Polo, 50% sus.c. (1.0 l/ha), Kapito, 50% em.c. (0.25 l/ha), and Desis, 2.5% em.c. (0.7 l/ha) were tested against the pes
