Abstract

The objective of the study was to investigate the effect of growth regulators based on humic substance derivatives on the growth and development of corn plants on sod-podzolic soils of the forest-steppe zone of the Chechen Republic. The study was conducted in 2024 in the forest-steppe zone of the Chechen Republic. The early-ripening corn hybrid Krasnodar 291 AMV was used in the experiment. About 25 species of weeds, representatives of 20 families, were identified in corn crops of the forest-steppe zone of the Chechen Republic. The type of weed infestation is mixed: annual - 60.5%, perennial, respectively - 39.5%. Against the background of the use of the growth regulator, there was a decrease in the species diversity of weeds, which is associated with an increase in the competitiveness of corn. The same pattern was recorded for pests and diseases. The use of growth regulators based on humic substances for pre-sowing seed treatment made it possible to reduce crop losses. Under control, the yield was 10.13 t / ha. With a weed infestation of 3 pcs/m2, the yield is 9.80 t/ha or yield losses amounted to only 0.33 t/ha (3.30%). With 384 pcs/m2, the yield decreased by 2 times and amounted to 4.98 t/ha. The use of plant growth regulators in corn crops allows to increase the competitiveness and yield of the crop, to increase the yield and the level of agricultural culture in general.
