Influence of growth regulators based on natural humic substances on the competitiveness of plants of different potato varieties in the forest-steppe zone of the Chechnya Republic

Abstract: The objective of the study was to evaluate the feasibility of using plant growth regulators based on natural humic substances to reduce the critical period of weed damage as a reservoir of non-target species in the agrocenosis of various potato varieties in the forest-steppe zone of the Chechen Republic. The study was conducted in 2025 in the Gudermes district. The experiment involved domestic early-ripening table potato varieties Red Lady and Rosanna, zoned in the Chechen Republic. Humate+7, a preparation based on natural humic derivatives (produced in Irkutsk), was used as a growth regulator in the experiment. The field experiment was modeled against a background of mixed weed infestation with a predominance of annual weeds. The study demonstrated a positive effect on the competitiveness of pre-planting potato tubers treated with a 0.1% solution of a growth regulator based on natural humic substances. A decrease in weed species was observed, indicating increased competitiveness of potato plants and the potential for reducing the need for protection against non-target pests. The critical period for weed damage in potato agrocenoses was 25 days for the Red Lady variety and 29 days for the Rozanna variety. The use of a plant growth regulator for pre-planting tuber treatment reduced the critical period to 20 days for the Red Lady variety and 27 days for the Rozanna variety. The use of Humate+7 for pre-planting treatment of early-ripening Red Lady potato tubers is undisputed.
