The results of research of influence of the protracted application of fertilizers are reflected on podzolized chernozem in the field crop rotation in the conditions of Right-bank Forest-steppe of Ukraine on the physical and biochemical indexes of quality of grain of soft winter wheat, the predecessor of that were peas. The 50-years fertilizing application led to the derivation of different levels of soil status. The fertilizing had positive, but different impact on the yield of winter wheat. On average, over the three years of research the yield was the lowest on unfertilized soils (at the mineral system of fertilizer on 31–71 organic – 28–60 and organo-mineral it is Set on 35–73%), that the greatest indexes of quality were provided by application of high norms of organic and mineral fertilizers in the field crop rotation (of N135P135K135 on 1 hectare areas of crop rotation) – 14,2–14,4 protein, and 28,2–28,6 gluten 1 groups of quality. Although, fertilizers changed the indicators but they remain within the same group. In 2014 its quality was satisfactory, that fact was caused by rainy weather conditions during grain-filling period and harvest. On average, over three years of research the fibrin compliance was 25 cm (without fertilizing application). Applying high fertilizer quantity caused the slight increase of this index. At the terms of the sufficient moistening it was formed by semiglassy, and top-dressed assisted some increase of this index (on 5–13%) depending on their norms. Set crowd conditions of connection after the coefficient of correlation between mass 1000 grains and nature of grain was considerable (r = 0,65), and between mass 1000 grains and by the productivity – strong (r = 0,76). Weather terms and fertilizers substantially influenced on grain hardness. At the terms of the sufficient moistening it was formed by semiglassy, and top-dressed assisted some increase of this index (on 5–13%), depending on their norms. When the norms of N, P2O5, K2O in mineral, organic and organo-mineral fertilization programs were equal, the significant differences were not found.
