The influence of preparations based on biologically active substances on the yield and quality indicators of potatoes in the conditions of the mountainous zone of the Kabardino-Balkarian Republic

Abstract

In the conditions of the Kabardino-Balkarian Republic, in the mountainous zone, field studies were carried out to identify the effectiveness of the use of drugs based on biologically active substances on the yield and quality indicators of potatoes in the mountainous zone of the Kabardino-Balkarian Republic. The following potato varieties Goryanka and Nart 1 were studied as objects of research. The following preparations were the subject of research: Lignohumate AM, Polydon iodine, Fulvigrain Stimulus Pro, Zircon and BisolbiSan, Zh, Succinic acid. Analysis of the data obtained in the course of the research shows that in the variants of the combined use of Lignohumate AM and preparations based on biologically active substances, a stable and high increase in potato yield was noted in all years of the study. The highest yield for the Goryanka variety was noted in the variants of joint application with the Zircon preparation - 8.1 t/ha or 34.5%, for the Nart 1 variety in the variant of the combined application of BisolbiSan - 10.7 t/ha or 36.0%. The use of the drug Lignohumate AM led to an increase in the yield of tubers for varieties Goryanka and Nart 1 by 22.6% and 26.3%, respectively.
