Soybean (Glycine max (L.) Merr.) is a legume valued, among other things, for the high nutritional value of its seeds. It plays an important role in crop rotation, improving soil fertility and structure. Therefore, research aimed at determining the optimal agrotechnical conditions for obtaining high yields of this plant is crucial. The purpose of this research was to evaluate the yield of two soybean cultivars sown at varying row spacing under pro-ecological and conventional methods. A four-year field study proved that conventional cultivation had a more favorable effect than pro-ecological cultivation on seed yield, plant density after emergence, number of pods per plant and number and weight of seeds per plant. In pro-ecological cultivation, soybeans set pods significantly higher. The Merlin cultivar turned out to be a better yielder than Aldana (by 43.4%), in which the elements of crop and yield components were also more favorable. Significantly higher soybean seed yield was obtained at a row spacing of 22.5 cm than 35 cm.
