Today, global climate change, along with drought, the processes of soil degradation are becoming one of the urgent problems for scientists all over the world. In this regard, a number of works are being carried out in Uzbekistan. According to the National Report on the State of Land Resources of the Republic of Uzbekistan, only 10% (4.3 million ha) of the 44.9 million hectares in the Republic are irrigated. About 2 million hectares (45%) of these lands are subject to secondary salinization. There are problems with water erosion on 800,000 hectares and wind erosion on 2 million hectares. The object of the study is dark serozem soil belonging to the region of mountain and sub-mountain soils, formed under complex climate and relief conditions. morphological characteristics of these soils in the profile, changes in some properties of these soils according to different exposures and slopes of the slope, including non-eroded watershed, moderate and strongly eroded transit, and corresponding changes and washing in washed-accumulated horizons information on monitoring processes is given.

The article presents data from research conducted under high temperature conditions with various salt-tolerant plants. The possibility of using them for various purposes, as well as for improving saline soils, is being considered.

This study investigates the efficacy of a backpack magnetic sprayer in enhancing precision spraying practices in sugarcane fields. Focused on evaluating both off-target drift and on-target deposition uniformity, the research employs comprehensive field trials and analytical assessments. Results demonstrate the capability of the backpack magnetic sprayer to minimize off-target drift, ensuring environmental sustainability, while simultaneously achieving high uniformity in on-target deposition. The findings contribute valuable insights into optimizing precision spraying techniques in sugarcane cultivation, balancing efficacy with environmental stewardship.

The article highlights the evolutionary development of the change in morphological features of the eroded meadow soils of the Ferghana Valley under the influence of anthropogenic factors.

This study investigates the optimization of mango juice clarification using Aspergillus niger cellulase through response surface methodology (RSM). Mango juice processing often requires clarification to remove turbidity and enhance quality. Enzymatic treatment offers a sustainable alternative to traditional methods, and Aspergillus niger cellulase holds promise due to its ability to degrade pectin and other cell wall components. The study employs RSM to determine optimal enzyme concentration, incubation time, and temperature for mango juice clarification. Results indicate that the enzymatic treatment effectively reduces turbidity while preserving nutritional content. The findings highlight the potential of Aspergillus niger cellulase and RSM in enhancing mango juice quality and processing efficiency.

In the article, data was given on effect of planting of schemes on rice growth, development and biometric indicators. According to it, Iskandar and Ilgor varieties of rice in the scheme 30x10x1 when planted, rice biometric indicators was observed well.

The comprehensive study of changes in the content of cytokinins, indole acetic acid (IAA) and abscisic acid ABA, growth rates, and development of potatoes during soil salinity NaCl. Studies have shown that the hormonal balance of potato organs throughout ontogenesis under the influence of NaCl salinity undergoes significant changes: the content of cytokines and auxins decreases, the level of ABA increases, as a result, the ratio of cytokines +IAA/ABA falls. These changes in the hormonal balance are not only the result of a stress response but also have an adaptive value. The conducted research allowed us to find out the relationship between changes in hormonal balance and physiological processes.
