Agricultural production systems are complex socio-technical and bio-physical constructs shaped by soil properties, plant physiological processes, technological interventions, water availability, and decision-making under uncertainty. The present research develops a comprehensive, theoretically grounded, and methodologically integrated framework for understanding and optimizing tillage systems, land-reclamation technologies, and water use practices within modern agriculture. Drawing strictly on established agronomic, physiological, engineering, and systems-analysis literature, the article synthesizes classical foundations of crop rotation and soil management with contemporary approaches to multicriteria optimization, intelligent decision support, and uncertainty handling in land-reclamation technologies.

The study situates tillage and soil preparation as central mediating processes between natural soil dynamics and anthropogenic agricultural objectives. Special attention is given to the physical transformation of soil structure, resistance, aggregation stability, and organic carbon dynamics as influenced by traditional and innovative tillage practices. These transformations are examined not as isolated mechanical effects but as system-level phenomena that directly affect water infiltration, root development, nutrient uptake, and ultimately plant productivity. By integrating plant physiology perspectives, the article demonstrates how soil mechanical and hydrological conditions interact with plant metabolic processes, stress responses, and growth regulation.

Methodologically, the article advances a descriptive but rigorous framework for parameter optimization in agricultural and land-reclamation technologies, grounded in systems analysis and fuzzy approximation theory. Multicriteria decision-making approaches are examined as essential tools for navigating the inherent trade-offs among productivity, energy efficiency, soil conservation, and water sustainability. The role of uncertainty, both epistemic and environmental, is analyzed in depth, emphasizing the need for intelligent decision support systems capable of synthesizing heterogeneous criteria without reducing complex realities to simplistic numerical optima.

The results of this integrative analysis reveal that optimal agricultural outcomes cannot be achieved through singular technological interventions or isolated efficiency metrics. Instead, resilience-oriented optimization emerges as a guiding principle, where adaptive tillage strategies, informed water use policies, and flexible decision-support algorithms collectively enhance system stability and long-term productivity. The discussion critically evaluates limitations of existing approaches, including over-mechanization, data scarcity, and institutional constraints, while outlining future research pathways focused on intelligent, context-sensitive agricultural systems.

By unifying agronomy, plant physiology, agricultural engineering, and systems optimization theory, this article contributes a holistic conceptual foundation for sustainable land management in water-constrained and uncertainty-prone agricultural environments.

Photosynthetic microorganisms in agricultural soils may contribute to organic matter production, extracellular polymer formation and nutrient transformations, but their functional significance cannot be inferred from a taxonomic inventory alone. This quantitative secondary synthesis examines the relevant regional evidence and develops an analysis-ready soil–algoflora monitoring framework for the irrigated agroecosystems of Quva district, Uzbekistan. Historical Fergana Valley observations comprising 159 reported algal species and infraspecific taxa were reanalysed by seven morphological categories and by a six-division × five-soil-type table. Coccoid forms represented 63 taxa (39.62%) and simple filaments 51 (32.08%), together accounting for 71.70% of the regional list. Regional soil-type inventories ranged between 63 and 109 taxa, with notable differences in the proportional representation of cyanobacteria and green algae. Literature-reported algal abundance was 19.0–60.0 thousand cells per gram of soil overall, while ranges for individual broad groups were also documented. These endpoints are literature ranges, not uncertainty intervals, and cannot be combined to estimate simultaneous community structure. No Quva-specific paired biological and physicochemical samples were identified in the datasets analysed; thus no novel species records or correlation coefficients for Quva are claimed. Building on critical literature about algal exopolysaccharides, photosynthetic carbon assimilation and nitrogen-related pathways, we specify which measured variables, experimental units and statistical procedures are required to examine possible relationships between algal traits, salinity, organic carbon and nutrient status. The contribution is an auditable numerical reference and an explicitly testable framework for original research in irrigated Quva soils.

As a result of the conducted studies, it was found that alcoholic and aqueous extracts prepared from the Inula grandis plant have significant antiradical activity against DPPH free radicals. Spectrophotometric analyses based on the DPPH method showed a consistent increase in antiradical activity with increasing extract volume and incubation time. Based on the results obtained, the scientific and practical significance of the Inula grandis L. plant as a natural antioxidant source is demonstrated.

During the research, the species composition of Aphidiidae family representatives, particularly Lysiphlebus fabarum Marsch, and their biological effectiveness against plant aphids were widely studied and scientifically substantiated in managing the number of sucking pests of vegetable crops. The studies were mainly carried out in vegetable-growing fields infested with aphids in the districts of Tashkent and Syrdarya regions, as well as in scientific research laboratories specializing in biological plant protection. The most widespread plant aphids Aphis craccivora Koch, Aphis gossypii Glow, Rhopalosiphum nymphaeae, Brevicoryne brassicae and the infestation rates of their effective parasitic entomophage Lysiphlebus fabarum Marsch were examined.

Developing early maturing and high yielding soybean cultivars is essential for improving production efficiency and ensuring crop stability under increasingly variable climatic conditions. In this study, eight soybean genotypes were evaluated under competitive variety testing conditions in 2020, with the early maturing cultivar ‘Orzu’ serving as the standard check. Field trials were conducted in 14 m² plots at a sowing density of 400,000 seeds ha⁻¹, and phenological, morphological, reproductive, and yield-related traits were comprehensively assessed.

Growth duration among the tested genotypes ranged from 88 to 102 days, compared with 109 days for the standard cultivar. Lines L 125 and K 9182 matured 18–21 days earlier than Orzu, demonstrating strong potential for short season environments. Considerable variation was observed in plant height (72–122 cm), first pod height (10–17 cm), number of branches (1–3), and pods per plant (72–136), indicating significant morphological diversity within the evaluated germplasm.

Seed yield varied from 210 to 375 g/m², with the highest productivity obtained from L 125, which also displayed the greatest pod setting capacity. Correlation analysis further confirmed that yield was most strongly influenced by the number of pods per plant (r = 0.91), while early maturity exhibited a negative relationship with yield (r = –0.72), reinforcing the value of early maturing, intensively fruiting genotypes.

Based on integrated trait evaluation, genotypes L 125, K 122, K 137, and K 171 were identified as promising breeding sources for future cultivar development. The superior line L 125, later named ‘Zarbuloq’, was submitted to the State Variety Testing Commission for official evaluation due to its high yield potential, early maturity, and favorable plant architecture.

The article presents scientific research conducted on the introduction and acclimatization of effective species of the Trichogrammatidae family. The study mainly focuses on the introduction and acclimatization of the species Trichogramma ostriniae. This species is considered an effective parasitic entomophage of representatives of the order Leoidoptera occurring in the maize agrobiocenosis. In the conducted research, trichogramma species were introduced and acclimatized under biolaboratory conditions. During the acclimatization process, scientific studies were carried out on feeding, reproduction, and storage of trichogramma. When breeding trichogramma in the biolaboratory, 65% relative humidity and an air temperature of +27-280C were maintained. It was determined that the introduced Trichogramma ostriniae produced 8 generations per year under biolaboratory conditions.
