Abstract

The work presents studies of preparative laboratory forms of preparations containing nanoparticles of macro- and micronutrients by inclusion of stabilizers and solution modifiers on growth and development of spring triticale plants in the first phases of ontogenesis and spring wheat under field conditions. The preparations and their rates positively affecting germination energy, germination rate with the effect of 4-6% and plant growth under the influence of preparations on daily seedlings were isolated in laboratory studies. The preparations Mn, 10 ml/t, Ca, 10 ml/t, Mo, 50 ml/t, Titan M, 50 ml/t, biogenic Fe, 5 ml/t had a positive effect on energy and germination, while the preparations Mn, 10 ml/t, Ca, 10 ml/t, Mo, 50 ml/t, Titan M, 50 ml/t, biogenic Fe, 5 ml/t, Bor 5 mg/g + GC (10%) had a positive effect on sprout length, 1ml/t, Potassium, 1000 ml/t of which the variants with Boron 5 mg/g + GC (10%), 1ml/t, Potassium, 1000 ml/t had the greatest and significant effect, where the increase in sprout length was 1.0-3.2 cm or 7.8-25%, mass 0.5-1.4 g or 6-8%. In field studies, we evaluated the use of biogenic iron in the plant protection system as a stimulant in the treatment of seeds together with a seed dressing and plants during the growing season. The effect of the preparation on the development of plants contributing to increased yield was determined, especially the treatment of wheat plants in the earing phase, which provided an increase of 0.5 t/ha.
