Abstract
The objective of the study is to evaluate the effectiveness of the complex use of herbicides and growth regulators on corn in the forest-steppe zone of the Chechen Republic. The study was conducted in 2024 in the forest-steppe zone of the Chechen Republic. Against the background of pre-sowing seed treatment with the natural growth regulator Gumat+7 at a concentration of 0.01%, the yield of the early-ripening corn hybrid Krasnodar 291 AMV in control 1 (without herbicides and weeding) was 4.10 t/ha. The greatest yield increase was noted when using Superkorn, MD at a dose of 1.0 l/ha 2.82 t/ha, which is 68.7% compared to the control. A slightly lower yield increase was obtained when applying the herbicide at a dose of 0.7 l/ha - 2.00 t/ha, which amounted to 48.7% compared to control 1. In hybrid corn crops, the most effective way to control weeds in the forest-steppe zone of the Chechen Republic is to use the domestically produced herbicide Superkorn, MD at a dose of 1.0 l/ha in combination with pre-sowing seed treatment with the natural growth regulator Humate+7 at a concentration of 0.01%.
