Abstract
Soybean yield depends on the variety, soil, cultural practices, as well as the weather conditions in certain years. The aim of this research is to examine the impact of NPK fertilizer application in the autumn and spring period on the level of soybean yield. The highest soybean yields were achieved by applying NPK fertilizer in autumn, before the basic tillage with spring application of nitrogen fertilizer AN. Spring application of NPK fertilizers and AN increases the yield, but the effect of fertilizers is significantly less compared to autumn application. The application of nitrogen fertilizer AN increases the soybean yield, and in order for this fertilizer to show its full effect, it is necessary for the soil to be optimally provided with macroelements.
