Abstract. The article examines the features of soybean yield formation under alkaline and saline soil conditions in Azerbaijan and proposes approaches for adapting cultivation technology to these environments. The study is based on the analysis of soil samples collected from a depth of 0–30 cm, characterized by elevated electrical conductivity (EC 1.12–1.19 dS/m), alkaline soil reaction (pH 8.5–8.7), and excessive concentrations of sodium and chloride ions. It was found that these factors adversely affect plant water relations, the availability of micronutrients, and the processes of symbiotic nitrogen fixation. The need for an integrated management approach, including chemical reclamation, optimization of the water regime, application of organic and mineral fertilizers, and seed inoculation, is substantiated. The proposed system of measures enhances the efficiency of soybean cultivation on degraded soils and contributes to stable crop productivity.
