The effect of biostimulants on Solanum tuberosum L. variety “Zakhar” in arid conditions of Orenburg Cis-Urals

Abstract

The article presents the results of a study of biostimulants Fitosporin-M, Zh (AS) + amino acids and Bionex-Kemi, Zh, (NPK 21:4:4) + ME on potato productivity indicators. As a result of1 the research, a positive effect of biostimulants on the growth and accumulation of underground biomass of Solanum tuberosum L. variety "Zakhar" was established. The analysis showed that when Solanum tuberosum L. plants of Zakhar variety are treated with Bionex-Kemi, Zh, NPK 21:4:4 + ME, the content of starch in tubers increases by 1.3 %, and when plants are treated with Fitosporin-(M, F (AS) + amino acids) - by 0.9 % in comparison with the control variant. The accumulation of underground potato biomass was more intense when using Bionex-Kemi, G, (NPK 21:4:4) + ME. For the cultivation of potatoes in the conditions of the Orenburg Cis-Urals, it is recommended to use the biostimulator Bionex-Kemi, Zh, (NPK 21:4:4) + ME (bioactivated nitrogen-phosphorus-potassium fertilizer), which stimulates plant growth and the accumulation of underground biomass.
