EFFECTIVENESS OF BIOLOGICS AND MINERAL FERTILIZERS APPLICATION IN FORMATION OF WINTER WHEAT CROP

Abstract

In the conditions of 2023-2025, the field experiments were conducted on the territory of the steppe zone of the Kabardino-Balkarian Republic to evaluate the effectiveness of the use of the growth stimulator LignoHumate AM and complex organic fertilizers CompleMet Zerno Impulse, Revitoplant Zernovye + BIO on winter wheat crops of Krasa Don and Taulan varieties. The purpose of the research was to improve agrotechnical practices to increase yields and to improve the quality characteristics of food grains. The research was carried out under the conditions of dry-land agriculture on chernozem soils of the steppe zone of the Kabardino-Balkarian Republic (KBR), using two promising varieties of winter wheat such as Krasa Dona and Taulan. The results of the vegetation experiments confirmed a positive effect of the studied agrochemicals on the growth, development and productivity of winter wheat. The maximum productivity was noted on both studied varieties when using the complex fertilizer CompleMet Zerno Impulse. The yield of the Taulan variety was 5.20 t/ha, and the Krasa Don variety was 5.19 t/ha, which is 0.7 and 0.8 t/ha, or 15.6 % and 18.2 %, respectively, more than in the control plots. The economic efficiency of using the fertilizer CompleMet Zerno Impulse turned out to be the highest. When using the Taulan variety, a conditional net income of 26.46 thousand rubles/ha was obtained, and the profitability level was 78.4 %. The Krasa Don variety had the highest yield (5.19 t/ha) in this experiment, and the profitability level was 74.2 %. Thus, the use of the complex fertilizer CompleMet Zerno Impulse is effective in cultivation of winter wheat varieties Krasa Don and Taulan in the steppe zone of the Kabardino-Balkarian Republic.
