Thickness of Winter Wheat Seedlings and Physical Properties of Soil
Get PDFThis article highlights the effect of sowing winter wheat on the density and porosity of the soil under the conditions of typical gray soils in the Tashkent region with different soil tillage and two different seeding rates
Study the Anatomical Descriptions, Histological Observation and Ultra-Structural of the Salt Glands in Domestic Duck (Anas platyrhynchos)
Get PDFThe present study aimed to investigate anatomical, histological and ultra-structural study of salt glands in adult domestic ducks .Anatomically, The salt glands in domestic duck of both control and salt stressed were crescent in shape with two pointed anterior and posterior extremities. The dorsal boarder was carved while the ventral boarder which face the eye ball was concaved. The gland was firmly attached with supra orbital depression, the skin of the head directly covered the gland. when the ducks drinking salinated water, the salt glands are engorged, the color become dark red and increased in size and weight.
Histological changes of stressed salt glands were hypertrophied and highly vascular with decrease connective tissue when the ducks exposed to sustained osmotic stress by replacing the drinking fresh water to brackish water (salt water 3%). In ultra-structural study of salt glands, when the ducks drinking salinated water, the principal cells contain large spherical nucleus with (euchromatin) and numerous elongated oval mitochondria (large in size) with secretory granules and development of numerous basal folds generally invested the cytoplasm to the level of the nucleus with abundant ribosomes. Also between the principal cells there was clear occurrence of complex junction and desmosome between the lateral membranes of principal cells. Which prevent the transport of material and ions between the lumen and the under lining connective tissue and blood vessels
Theoretical Foundations of The Concept, Classification and Optimization of Commercial Banks' Income and Expenses
Get PDFIn the article, the theoretical basis of the concept, classification and optimization of the income and expenses of commercial banks and the processes of income and expenses in banks are organized. Banks carry out their operating expenses within the framework of the estimated allocations approved and reported by their main bank for one year. Bank's operating expenses According to the estimate, the head of the bank disposes of the loans. The head of the bank has the right to issue an order on the bank and entrust the right to dispose of estimate assignments to his deputy.
 
Effect of Melioration Drug on Chemical Degradation of Soils
Get PDFAmong the stresses due to chemical degradation, soil salinity is a very serious environmental stress for soil bioindicators, reducing productivity in irrigated lands worldwide [1]. The study of the role of bioindicator enzyme activity in activating the mechanisms of the soil fertility improvement mechanism and the scientific analysis of the effect of soil salt indicators on soil processes serve as a basis for increasing soil health quantitatively and qualitatively. A series of bioindicator biochemical and enzymatic activity processes are activated under saline stress in the soil buffer. It is important to scientifically substantiate the effect of salt stress on biochemical processes on soil degradation. It serves to increase the efficiency of the biosolvent chemical meliorant used in the assessment of soil fertility and its parameters. mitigated the negative impact. In this article, the relationship between the level of soil salinity and urease enzymes in moderately saline alluvial soils degraded by salinity, which accelerates chemical degradation, was studied. Simple options were applied to soils not washed with biosolvent and selected for testing
Historical Origin of the Medicinal Godji Plant
Get PDFGoji, goji berry, or wolfberry (Chinese: 枸杞; pinyin: Gǒuqǐ) is the sweet fruit of Lycium barbarum or Lycium chinense, two closely related species of boxwood in the nightshade family, Solanaceae. The fruits of L. barbarum and L. chinense are similar, but can be distinguished by differences in flavor and sugar content
Ecological Stability, Plasticity and Adaptability of Sweet Pepper Lines
Get PDFThe success of breeding work depends on the accuracy of the assessment of traits characteristic of the parental forms. To do this, a preliminary individual assessment of each variety sample is carried out under specific growing conditions. It is necessary not only to study the breeding material, but also to identify ways to involve it in breeding work
Studying the Expressiveness of Color in Sur Lamb of the Karakalpak Breed Type
Get PDFKarakalpakstan is one of the large Karakul breeding regions of Uzbekistan and the main breeding base for breeding Karakul sheep of the Karakalpak breed type of original colors. In connection with the above, establishing some boundaries for the manifestation of selection traits in sheep of a given color is considered relevant. The article presents the results of studies on the severity of colors and length of curls in offspring obtained from a homogeneous and heterogeneous selection of Karakalpak sur sheep of different colors. The assessment of the resulting offspring was carried out in accordance with the “Instructions for conducting breeding work in Karakul breeding and evaluation (grading) of Karakul lambs.” As a result of the studies, it was established that, depending on the colors of the parents and their selection in different variants, there is a significant variation in the yield of lambs in terms of the severity of colors. A significant superiority of homogeneous selection of sheep of the “Candle-flame” coloring was established compared to other selection options for the yield of lambs with a strong color expression (90.0±3.0%). This superiority compared to the second selection option was 22.0%, the third -35%, and the fourth - 51.0%. The results showed the presence of a certain dependence of the length of the curls on the colors of the mated parents. At the same time, the offspring obtained from the selection “Candle-flame x Candle-flame” significantly exceeds (P<0.001) in terms of the yield of long-curl lambs (60.0±4.89%) the indicators of other options (25.0-31.0%). In the last three selection options, the offspring mainly had curls of average length (52.0-58.0%)
Introduction of Good Agricultural Practices within the Framework of the Agrodev Project
Get PDFAgriculture is one of the dominant sectors of the economy of Uzbekistan and is developing intensively. The last three to four years can be called a period of unprecedented comprehensive reforms in the agricultural sector, including the introduction of market mechanisms, advanced technologies in the agricultural sector and the transition to a cluster production system. One of the priority areas of the “Strategy of Action for the Further Development of the Republic of Uzbekistan”, adopted at the beginning of 2017, is the modernization and intensive development of agriculture. On October 23, 2019, the “Development Strategy for Agriculture of the Republic of Uzbekistan for 2020-2030” was adopted. The priority areas for the implementation of the Strategy are the implementation of state policy in the field of food security, ensuring food safety and improving consumer demand, and producing food products in the required volume
Classification of Interrogative Sentences
Get PDFSentence is a main unit of human interaction. Language units such as words, phrases, idioms express their meanings only in a sentence. The main purpose of the sentence will be formed in three types: sharing information (indicative sentence), requesting information (interrogative sentence), expressing orders and commands (imperative sentence). In this article, we present views on interrogative sentences (IS) and their description
