ABSTRACT

Open-field tomato cultivation is currently very important. This is due to a number of factors. The objective of the study was to evaluate the feasibility of using plant growth regulators based on natural humic substances to enhance the competitiveness of tomato plants in the forest-steppe zone of the Chechen Republic. The study was conducted in 2025. The use of a growth regulator significantly reduced the diversity of non-target species in Lyubimets Kubani and Madlena tomato varieties. Madlena tomato plants are more sensitive to humic derivative-based preparations. This suggests both intraspecific and interspecific competition in the tomato agrocenosis. Pre-sowing treatment of tomato seeds with a growth regulator solution has been shown to have a positive effect on increasing competitiveness. A reduction in the diversity of non-target species in the agrocenosis is also noted, which can be considered an indirect sign of increased competitiveness. Under weed-free control, the Lyubimets Kubani tomato variety yield is 31.00 t/ha. At maximum weed infestation, yield losses were 17.9 t/ha, or 41.9%. The use of Humate+7 reduced yield losses to 28.7% at maximum weed infestation. Yield losses for the Madelena tomato variety were lower. The yield during control was 29.00 t/ha, while at maximum weed infestation, yield was 17.80 t/ha, or 38.0%. Pre-sowing seed treatment with 0.1% Humate+7 reduced yield losses to 26.0%. Therefore, the advisability of using growth regulators for pre-sowing tomato seed treatment is clear.
