Testing of macro- and micronutrient nanoparticles on grain crops

Abstract

The studies were conducted in the northern forest-steppe of the Tyumen region. Under laboratory and field conditions, different forms and dosages of macro- and micronutrient nanoparticles and associated substances were tested in the treatment of seeds and plants of spring triticale and wheat. The preparations had a positive effect on seed germination, while higher rates reduced energy and germination. The germination energy and germination of triticale seeds increased by 4-10% with the application of preparations containing nanoparticles of copper, manganese, molybdenum, biogenic iron, Titan M. Treatment of daily seedlings with manganese, calcium, molybdenum, Titan M, biogenic iron, boron, potassium increased sprout length by 7.8-25% and sprout weight by 6-8% by day 7. Only already developing sprouts responded to the application of potassium. It was noted that the application of biogenic iron causes a 4-10% decrease in laboratory germination of seeds, but promotes the development of the main root. Its increase was 9-12% compared to the control. The inclusion of biogenic iron and silicon in the mixture to the chemical dressing reduced the effectiveness against root rot from 18% at the beginning of the growing season to 30% by the harvesting period. The application of biogenic iron increased the yield by 0,5-0,6 t/ha or 23% in the system of complex crop protection compared to the control and by 0,16-0,23 t/ha with the standard scheme of crop protection. A positive effect of biogenic iron in the treatment of plants during the earing phase as a separate element of the technology and in a tank mixture with fungicides was noted.
