The article presents the results of studying the ecological and biological features of soybeans of the northern ecotype in the conditions of the middle taiga of Western Siberia (Surgut). For the first time, a comparative assessment of the biological characteristics of soybeans of the SK Artika variety was carried out, the features of ontogenesis and biomorphological signs were revealed, the results of feed assessment and productivity were presented, the possibility of cultivating soybeans for feed in extreme soil and climatic conditions of the Khanty-Mansiysk Autonomous Okrug was established. Materials and methods. Studies on the assessment of the biological characteristics of soybeans of the ‘SK Artika’ variety were conducted on the basis of the Botanical Garden of the Surgut State University of the Khanty-Mansiysk Autonomous Okrug. The object of study is an annual soybean bean crop, a variety of ‘SK Artika’. Results. As a result of the introduction study, it was found that due to the lengthening of the virginal period of the introducer, a high collection of green mass was noted. The height of the introduced stem and yield did not differ significantly from similar studied indicators of soybean varieties of the northern ecotype cultivated in the soil and climatic conditions of Bryansk. It was recorded that the onset of the generative phase takes place at a lower sum of active air temperatures (763 оC), unlike in Bryansk (2150-2300 оC) during the growing season. However, at the same time, there is a loss of the phase of the period of waxy and full ripeness of the beans.
