The use of Siliplant as a growth regulator in potato cultivation in the arid zone of the Northern Caspian region

Introduction. An important element in the technology of cultivation of various crops, including potatoes, contributing to the stimulation and stabilization of yield indicators corresponding to meteorological conditions, is the use of growth regulators and micronutrients in chelated form. The updated correction of the dynamics of plant growth and development, as well as the intensification of their adaptive capabilities with the help of growth stimulants and "chelates", which allow achieving high plant productivity, increases the resistance of plants to adverse agro-climatic factors, leads to an increase in the potential yield of crops.

Object. Potato varieties were studied: Utenok, Ivan da Marya, Arosa.

Materials and methods. Studies on the use of the drug Siliplant were conducted at an experimental experimental field site in 2021-2023 on the basis of the farm "Zvolinsky O. V." of the Chernoyarsk district of the Astrakhan region according to the wellknown method of B. A. Dospekhov (2011).

Results and conclusions. An analytical analysis of the obtained material showed that the use of an organomineral preparation is quite effective, it contributes to an increase in yield, at the control it was 27.8 t /ha. The double combined use of Siliplant led to an increase in yield equal to 48.9 t/ha, which is 21.1 t/ha more relative to the control yield. Growth regulators in the processing of vegetative plants have shown their effectiveness in potato cultivation technology. In this study, the chelated organomineral drug Siliplant was studied, the effect on crop yield, on the productive work of the leaf surface, as well as photosynthetic potential, promotes the growth and development of tubers.
