Abstract: The paper investigates the peculiarities of mustard seed yield and quality formation depending on the use of mineral fertilizers. It has been determined that the use of mineral fertilizers increase the yield structure, which contributed to the increase in the seed productivity of mustard. On average, seed yields increased significantly by 0.32–0.56 t/ha in the varieties with the application of mineral fertilizers, both as the main fertilizer and together with foliar fertilization, compared to the control without fertilizers. The introduction of phosphorus-potassium fertilizers in the main fertilizer provided a significant in the yield of mustard seeds of all varieties, which ranged from 0.14 t/ha (Tsarivna Pivnochi) to 0.27 t/ha (Oslava). With the main fertilizer and foliar feeding with nitrogen fertilizers, seed yields increased significantly compared to the control, and the addition of phosphorus-potassium fertilizers to the main fertilizer. The greatest influence on seed yield was the «fertilizer» factor, which accounted for 85.1%, while the influence of the «variety» factor was much lower. Thus, in order to increase the yield of mustard seeds when grown in the conditions of the Right-Bank Forest-Steppe, it is advisable to apply P45K45 as the main fertilizer, and to carry out two fertilizations with nitrogen fertilizers at a rate of N15 and in the rosette-stemming stage at a rate of N30, which ensures high seed productivity of mustard.
