The results of studies on the influence of microelement fertilizers on the formation of productivi-ty and grain quality of spring triticale of the Ukro variety are presented. It was found that microele-ment fertilizers Azosol 36 Extra, Megamix-Azot, Megamix-Profi, Tsitovit and NanoKremny provided an increase in the parameters of photosynthesis of agrocenoses of spring triticale. The maximum value of the leaf surface of 42.5 thousand m2/ha, the photosynthetic potential of 1.03 million m2 d/ ha, the net productivity of photosynthesis of 6.29 g/m2 per day were noted with double foliar dressing during the tillering and heading phases with Azosol 36 Extra. Due to the application of foliar dressing with microelement fertilizers in chelated form, an increase in the yield of spring triticale of the Ukro variety was observed, together with an improvement in the technological properties of grain. According to the experimental variants, on average for three years, the grain yield was 3.84-4.43 t/ha. The increase in relation to the control ranged from 0.42-1.27 t/ha (13.3-40.3%). The highest yield of high-quality grain of 4.43 t/ha was obtained by double top dressing at the tillering and heading phases with the use of Azosol 36 Extra; an increase in grain yield was 1.27 t/ha (40.3%), grain unit – 796 g/l, glassi-ness – 63 %, raw gluten – 26.2%, protein – 15.1%.
