In this work we studied the effect of finished preparative forms with manganese nanoparticles (monohydrate sulfate) with different contents and inclusion of stabilizers and solution modifiers on the growth and development of spring triticale plants in the first phases of ontogenesis. A positive effect of manganese on the increase of seed germination energy and germination of spring triticale at the dosage of Mn 20 mg/g + (PVP), with the drug consumption rate of 5 ml/t, was found. In this variant, both manganese and polyvinylpyrrolidone (PVP) solution stabilizer are determined to be positive. The inclusion of collagen hydrolysate (GC) and Ag-K modifier in the combination of the stabilizer solution, where the Mn content is 10 mg/g, negatively affected and reduced the germination energy by 13-17% compared to the control variant. Increasing the manganese content in the samples up to 20 mg/g levels out the negative effect of Ag-K modifier on seed germination. A positive effect within 7 days in most variants, both on the length of the sprout and on its weight was traced in the application of manganese with its content in the samples of 20 mg/g with a rate of 1 ml/t.
