An increase in yield and product quality is achieved with a balanced nutrition of plants with macro- and microelements. Treatment with retardants during the beginning of stem elongation gives a positive effect due to increasing the productivity of the stem and the indicators of photosynthetic activity, improves the moisture sup-ply of plants by strengthening the root system of crops. All this ultimately affects the value of crop yields. The purpose of the research was to study the effect of complex trace element fertilizers and retardant growth regula-tors to optimize growth development conditions and increase the yield of winter wheat. In the course of the experiment, the effect of trace element fertilizers and retardant growth regulators on the elements of winter wheat crop structure was determined. The lowest value of plant height (62.9 cm) was noted in variants using non-root treatment with HEFK. Non-root treatment with Aquamix ST during tillering stage and with HEFK during stem elongation contributed to the formation of grain weight at the level of 0.936 g per ear and winter wheat yield of 4.94 t/ha.
