The effect of nanoparticles, multicomponent trace element preperation “Avatar-2 protection”, and microbial preparation “Azogran” on the productivity potato cultivar Suvenir Chernihivskyi in Polesia region conditions

Abstract

Improvement of conventional methods of potato growing is an important task of modern agriculture. Nowadays nanoparticles (NPs) gain increasing attention of scientists as promising tools for increasing productivity of crop cultures. NPs of such elements as Fe, Zn, B, Si, Cu, Co, Se and Ag can significantly increase potato productivity. Ag NPs show synergic effect with some microbial preparations. However, the influence of such elements as Zn and Se on the productivity of potato and joint application of NPs with microbial preparations for pre-sowing treatment are not studied sufficiently. The influence of Ti and I NPs on potato productivity, the influence of NPs on Ukrainian potato cultivars, the influence of NPs on the potato productivity in Polesia region conditions are not studied yet. The aim of the study was to investigate the influence of pre-sowing treatment of seed potatoes with Zn nanoparticles (NPs), Ti NPs, composition of Se + I NPs, composition of Zn + Ti + Se + I NPs NPs, “Avatar-2 protection” multicomponent trace element preparation, “Azogran” microbial preparation “Azogran” and the combination of “Azogran” preparation with the composition of Se + I NPs on the productivity of potato cultivar Suvenir chernihivskyi in the Polesia region conditions. Two small plot studies were planted for three years in order to conduct the study. Each small plot study had been performed on different soil types: soddy podzolic soil and alkaline chernozem. Studies were situated on the lands of the Institute of Agricultural Microbiology and Agro-industrial Production of National Academy of Agrarian Sciences of Ukraine. It has been found that the composition of Se + I NPs, “Azogran” microbial preparation and the combination “Azogran” preparation with the composition of Se + I NPs had the most prominent influence on the potato productivity, increasing it on soddy podzolic soil by 33.13; 38.34 and 45.35 % respectively and on alkaline chernozem by 10.97; 17.98 and 37.27 % respectively. The composition of Se + I NPs and “Azogran” preparation are shown to develop synergic effect. The results of the study suggest high efficiency of the use of nanoparticles in potato growing.
