INFLUENCE OF NEW FORMS OF AGROCHEMICALS ON WINTER WHEAT CROPS IN THE SOVIET URBAN DISTRICT

The research was conducted from 2022 to 2024 on the premises of K.V. Marchenko, a private farm enterprise located in the Sovetsky urban district of Stavropol Krai. The scientists focused on the Alekseich and Ksenia winter wheat varieties. The primary focus of the study was on innovative agrochemical products. Throughout the study period, winter wheat was preceded by a crop of the same variety. Mineral fertilizers were selected as the key element for analysis. The field experiment examined modern agrochemicals: Potassium Humate "Souffleur" and Polydon Bio Profi. Polydon Bio Profi is a liquid organomineral fertilizer containing a unique complex of active ingredients and is a highly effective means of improving soil health and increasing crop yields. Potassium Humate "Souffleur" is a complex concentrated organomineral fertilizer based on humic acids. The experiment was a two-factor study. Factor A is agrochemicals, factor B is cultivars. Ammophos and ammonium nitrate were used in the experiment as mineral fertilizers. The experiment was a production experiment, the area of the experimental plots was 5.0 hectares, three replicates. The highest accumulation of nitrogen in winter wheat plants was observed at the tillering stage, reaching 3.61%, after which the nitrogen level decreased to 0.50% by the time the grain was fully ripened. The highest yield was recorded with the use of the fertilizer combination fon + Polydon Bio Profi, which led to a significant increase in yield compared to the control variant, while with the use of another studied dose, the increase in yield was insignificant. The use of agrochemicals had a positive effect on the yield of winter wheat, regardless of the plant variety. Compared to the control variant, the addition of fon + potassium humate increased the yield by 0.20 t / ha, while the use of fon + Polydon Bio Profi increased it by 0.30 t / ha. In the variant with the Alekseich variety, agrochemicals contributed to an increase in yield by 0.21-0.28 t/ha, and in the variant with the Ksenia variety, by 0.20-0.38 t/ha.
