2025-12-09T06:51:35+00:00

The rational volume of an elastic container for a cotton-harvesting machine in the technology of harvesting, loading–unloading, and transporting cotton by a containerized method should be selected based on the productivity of the machine, the loader, and the transport vehicle, as well as the length of the run of the cotton field.

Determination Of Hydraulic Resistance Under Regulated Flow Conditions Of A River Channel

2025-12-16T01:29:06+00:00

This article covers the problem of determining the hydraulic resistance of the water flow under regulated channel conditions in the lower reaches of the Amu Darya River. New empirical relationships have been developed based on the relationship between morphological changes in the riverbed, water discharge, flow velocity, and channel roughness. In the study, field observation data for the Tuyamuyun, Kipchak, Nietbaytas, Samanbay, and Kyzylzhar hydroposts were analyzed, and the relationship between water discharge and average velocity was determined based on formula (13). The results showed that with an increase in water discharge, the channel roughness decreases and the hydraulic resistance of the flow changes accordingly. The practical values of the calculated Shezi coefficient and the Darcy coefficient were determined, and their influence on the kinematic parameters of the flow was assessed. The obtained results are recommended for use in the design of water management facilities and in the refinement of hydraulic calculations in regulated channels.

Fungal Species Isolated From Tomato Seeds Under The Conditions Of The Republic Of Karakalpakstan And Their Significance In Disease Epidemiology

2025-12-10T07:29:17+00:00

This study investigates the species composition and infection rates of phytopathogenic fungi associated with tomato seeds under the agro-climatic conditions of the Republic of Karakalpakstan. Six fungal species were isolated and identified, with Fusarium oxysporum f. sp. lycopersici exhibiting the highest infection rate. These findings provide a scientific basis for field evaluation of fungicides and support the development of seed health management strategies to improve tomato production.

The article delves into the territorial differences in the composition of agricultural production and the systemic features inherent in them. The agro-economic and geographical significance of the territorial placement of the system of population settlements and production infrastructure is also revealed. The study serves to assess the agricultural potential of the region and develop scientific conclusions for its improvement.

Mathematical Model Of Bank Erosion And Horizontal Deformations In The Riverbed

2025-12-16T01:34:44+00:00

This article presents a mathematical model describing the dynamics of bank erosion and horizontal deformations in the lower reaches of the Amu Darya River. The study focuses on the development of the erosion boundary along straight and curved riverbank sections. The process is analyzed as a time-dependent phenomenon characterized by varying intensities and stabilization phases. Empirical coefficients were introduced to express the relationship between the length and width of the erosion zone, enabling the determination of its geometric and temporal parameters. The model provides analytical expressions that characterize the shape and development rate of the eroded area, incorporating the asynchronous onset of stabilization for both longitudinal and transverse dimensions. The proposed theoretical formulations were verified using field data collected from the lower Amu Darya, showing an accuracy of 5–10%, which confirms the adequacy of the developed model for engineering applications.

Assessment Of Seed Germination Of Jujube (Ziziphus Jujuba Mill.) Under Field Conditions

2025-12-13T07:27:41+00:00

This article describes the possibility of determining the germination of Ziziphus jujuba Mill., seeds, and their quality indicators. The optimal sowing depth was determined by sowing the seeds at different depths in the field. The lowest indicator was 42.6% at a sowing depth of 1-1.5 cm. The highest indicator was 81.3% at a sowing depth of 2-2.5 cm. In addition, the germination time and duration of stratified and scarified seeds were determined in the regions. The germination of stratified seeds at a depth of 3-3.5 cm germinated in 11-13 days and the highest indicator was 63.6%, while the seeds sown at a depth of 2.5-3 cm had 81.3%. The time of stratification affects the germination of stratified seeds.

Comparative Assessment Of Vinegar Production Potential From Technical Grape Varieties In The Tashkent Region

2025-12-09T10:14:37+00:00

This study evaluates the technological potential of four distinct technical grape varieties – Pinot Noir, Bayan Shirey, Saperavi, and Cabernet Sauvignon for vinegar production under the specific pedoclimatic conditions of the Tashkent region, Uzbekistan. By systematically analyzing the initial sugar content, must volume, and subsequent dilution requirements, the research identifies the correlation between raw material composition and final vinegar yield. The results indicate that while red varieties like Pinot Noir exhibit superior sugar accumulation, the white variety Bayan Shirey demonstrates the highest total volumetric yield (1.6 L), driven by superior must extraction rates.
