The influence of nanoparticles, multicomponent microelemental fertiliser “Avatar-2 Zahyst” and microbial fertiliser “Azogran” on the yield of potato variety “Suvenir Chernihivsky” in Polissya

Abstract

Improving traditional potato growing technology is of great scientific and practical importance for agriculture. Recently, nanoparticles (NPs) have been catching the attention of scientists as a promising means of increasing crop productivity. It has been established that NPs of such chemical elements as Fe, Zn, B, Si, Cu, Co, Se, and Ag can significantly increase the productivity of potatoes. It is known that Ag NPs show synergism with some microbial agents. However, the effect of NP of such elements as Zn and Se on potato yield and NPs combined with microbial agents for pre-sowing fertilisation has not been studied sufficiently. The influence of Ti and I NPs on potato yield, the influence of ELs on the yield of domestic potato varieties, and the influence of ELs on potato yield in Polissya are not yet studied. The purpose of the study was to investigate the effect of pre-sowing fertilisation of potatoes with Zn NPs, Ti NPs, Se + I NPs, Zn + Ti + Se + I NPs, multicomponent microelement fertiliser “Avatar-2 Zahyst”, microbial fertiliser “Azogran” and a combination of microbial fertiliser “Azogran” with Se + I NPs on the yield of potato variety “Suvenir Chernihivsky” in Polissya. For three years in a row, small-scale experiments were set up on sod-podzolic soil and leached chernozem. The plots were located on the land of the Institute of Agricultural Microbiology and Agricultural Production of the National Academy of Agrarian Sciences in Chernihiv Oblast. The data obtained on the potato harvest was analysed in accordance with generally accepted methods of statistical analysis. It was found that among all variants of pre-sowing fertilisation, the composition of Se + I NPs, the microbial fertiliser Azogran and the combination of Azogran with the composition of Se + I NPs had the greatest effect on the yield of potatoes of the Suvenir Chernihivsky variety on sod-podzolic soil by 33.13, 38.34 and 45.35%, respectively, and on leached chernozem by 10.97, 17.98 and 37.27%. It was found that the composition of Se + I nanoparticles and Azogran exhibit synergism. The data obtained indicate high prospects for the use of NPs in combination with microbial fertilisers in potato cultivation
