NanoKremniy and Siliplant preparations stimulated growth processes, which contributed to an increase in the parameters of photosynthesis of spring triticale agrocenoses. The maximum values of the leaf surface – 34.6 thousand m2/ha, of the photosynthetic potential – 1.82 million m2 days/ha, of the net productivity of photosynthesis – 3.26 g/m2 per day, of the ear grain size – 36-38, of grain weight per spike – 1.2-1.3 g were observed during seed treatment and double foliar top dressing in the tillering and heading phase with the NanoKremniy preparation. When presowing seed treatment was used, the highest grain yield of triticale (4.05 t/ha on average over three years) was obtained using the preparation NanoKremniy. A reliable increase in the control amounted to 0.8 t/ha (32.5%). Silicon-containing preparations NanoKremniy and Siliplant contribute to improving the technological properties of spring triticale grains. Indicators of the grain unit on the variants of experience amounted to 776-781 g/l. The greatest indicator of the grain unit (781 g/l) was when the preparation NanoKremniy was used for seed treatment. The grain hardness in relation to the control increased by 4.0-11.0%, the content of raw gluten – by 1.5- 2.1%, of protein – by 2.7-3.1%. Foliar plant nutrition with silicon-containing preparations in different phases of the growing season had a significant impact on increasing yields and improving the technological properties of spring triticale Ukro grain. On average, over three years, the yield of grain according to the variants of the experiment was 34.4-4.49 t/ha, the increase relative to the control was 0.39-1.43 t/ha (12.5-48.6%). The highest grain yield (4.49 t/ha) was obtained by double feeding with the preparation NanoKremniy during the tillering and heading stages, the grain yield increase was 1.43 t/ha (48.6%). The maximum indicators of the technological properties of spring triticale grain were obtained by double foliar fertilization of plants with the NanoKremniy preparation: grain unit – 792 g/l, hardness – 62%, raw gluten – 26.2%, protein – 15.8%.
