ECONOMICAL EFFECTIVENESS OF THE PRE-SOWING SEED TREATMENT OF WINTER WHEAT WITH POLYFUNCTIONAL AGENTS

Abstract

In recent years, there has been growing interest in polyfunctional agents in
Russia. They have been actively used in agriculture. These agents represent a new generation
of growth regulating substances that are not only highly effective, but also have the ability to
cope with several problems at the same time. Modern agents are becoming an indispensable
tool for ensuring high productivity and sustainable development of agriculture in our country.
Therefore, the purpose of our research was to analyze the economical effectiveness of using
polyfunctional agents for the pre-sowing seed treatment. The research was carried out in
2019-2022 on the experimental field of the FSBSI “North Caucasus Federal Agricultural Research Centre”, which was located in the instable humidity zone of the Stavropol Territory.
The object of the study was the medium-sized winter wheat variety Stavka (Lutescens variety) and the flat-growing Viktoriia 11 variety (Erythrospermum variety). The predecessor was
winter wheat. Mineral nutrition background was N120P60K60. The greatest increase in yield, by
9,4% relative to the control variant, in Viktoriia 11 variety was obtained with the use of Alfastim and Ikar Fosto Seeds. The use of the polyfunctional agent Alfastim in Stavka variety
made it possible to obtain a yield of 4,77 t/ha, which was 9,2% higher than the control variant.
The average amount of crude gluten over the years of the research in Stavka variety was
28,2%, in Viktoriia 11 variety – 28,7%. The FDM parameter for Stavka variety ranged from
83,7 units (Sprintalga) up to 90 units (Biodux), in Viktoriia 11 variety – from 87,3 to 93,0
units (Ikar Fosto Seeds and Biodux). An analysis of the economical effectiveness of using
polyfunctional agents on winter wheat showed that the average profitability of the flatgrowing variety Viktoriia 11 was 67,9%, which was 12,4% more than the profitability of the
medium-sized variety Stavka. The greatest profit per 1 hectare was obtained when treating
seeds with the polyfunctional agent Alfastim for both Stavka and Viktoriia 11 varieties.
