The proposed methodology for increasing the efficiency of monitoring degraded reclaimed lands defines a unified approach and structure for conducting agricultural land monitoring in the country.  

The article presents the results of research on the development of new local varieties of chickpea adapted to unfavorable soil and climatic conditions in rainfed lands. These varieties are resistant to drought, heat, diseases, and pests, while also being high-yielding. The study highlights the importance of incorporating economically efficient leguminous crops into crop rotation systems to maintain and improve soil fertility, thereby increasing production. Additionally, the research describes the development of early-maturing, drought- and disease-resistant chickpea varieties with 15–20% higher yield and protein content compared to the standard variety. The study also covers the initial seed production of promising chickpea varieties recommended for cultivation in rainfed areas.  

The use of minimal and resource-saving soil cultivation technology improves its properties, rainfed areas are used especially effectively, and the yield and quality of grain increases. In this regard, through the effective use of soil moisture, maintaining soil fertility and increasing the yield of grain crops. The use of an optimal system of main and pre-sowing tillage is the most important and decisive agrotechnical measure for obtaining stable and high yields of grain and other products in rainfed farming conditionsThe use of minimal and resource-saving soil cultivation technology improves its properties, rainfed areas are used especially effectively, and the yield and quality of grain increases.

This article determines and draws conclusions on the changes in live weight across age dynamics of offspring obtained from mating Camelus dromedarius and Camelus bactrianus camels in various pasture conditions of the Ustyurt Plateau in the Republic of Karakalpakstan.  

The article below explains the effect of the studied factors on the yield of camelina sativa varieties grown at different dates (autumn, spring and summer) and norms in the conditions of typical sierozem soils of the Tashkent province. According to this, when camelina sativa plants were planted at different dates and norms, the yield increased with increasing norm. It was found that the yield in the autumn and spring periods was higher than when planted as a repeated crop.  

In this article, experimental trials were conducted to evaluate the efficacy of a new insecticide formulation, PILARURON 50% SC, against Aphis gossypii Glov., a pest currently infesting greenhouse-grown tomatoes in our Republic and negatively affecting crop quality. The product was tested at an application rate of 0,8–1,2 liters per hectare, and its insecticidal activity was determined.  

Salt stress is a major environmental challenge that impacts agricultural productivity worldwide. Tomato (Solanum lycopersicum), a widely cultivated crop, is highly sensitive to salinity, which affects growth, yield, and quality. Recent studies have shown that tomato plants have the ability to adapt to salt stress through mechanisms such as somatic and intergenerational priming memory. Somatic priming refers to the ability of an individual plant to enhance its tolerance to stress after a previous exposure, while intergenerational priming involves the transmission of stress-induced adaptive traits from parent plants to their offspring. This paper examines the physiological, molecular, and epigenetic processes involved in these priming mechanisms, highlighting how these forms of memory can contribute to improved tomato resilience in saline environments. Understanding these processes provides a foundation for developing salt-tolerant tomato varieties through breeding and biotechnological approaches.  

The article presents experimental results on the application of mineral fertilizers in the growth phases of soft wheat, Bakhmal-97 variety, durum wheat variety, Yaqut-2014 variety, barley variety, Mushtarak variety, depending on the type and rate of fertilizers, on the dynamics of soil moisture and the rate of crop feeding, grain quality and yield. According to the results, the optimal feeding rate for the application of mineral fertilizers in arable fields depends on the dynamics of soil moisture and for obtaining high-quality yields of soft wheat "Bakhmal-97" variety is N40P40K40 kg per hectare, durum wheat "Yakut-2014" and barley "Mushtarak" varieties The results of the study are presented on the optimal feeding rate of N50P40K40 kg per hectare for obtaining high-quality grain and high yields using mineral fertilizers at different growth phases.  

The article discusses the development of geospatial information support for addressing forestry issues, implemented in the form of a forest geoinformation system that ensures the resolution of multi-level management problems within the Republic of Uzbekistan.  

The article presents data on cotton irrigation planning, taking into account soil and hydrogeological conditions, natural and climatic factors of the region, and the cultivated variety. The study was conducted in response to the year-on-year increase in water scarcity in the Republic, including the Republic of Karakalpakstan. Existing meteorological indicators and the FAO methodology CropWat 8.0 program were used to plan cotton irrigation based on water demand. The scientifically based irrigation regime for cotton, developed by N.F.Bespalov based on the standard hydromodular zoning scale, according to the recommendations of scientists who conducted research in the conditions of the Republic of Karakalpakstan, provides for irrigation of cotton during the growing season in the northern zone: 3400 (IX) - 6400 (I) m3/ha and in the southern zone: 3800 (IX) - 7000 (I) m3/ha. Within the framework of FAO's CropWat 8.0methodology program, the cotton irrigation regime is planned using meteorological data from the region.
