Influence of the Composite Recultivant Trevitan on Growth Processes of Winter Wheat

The purpose of this study is to investigate the comprehensive effects of the innovative composite recultivant Trevitan® (CR Trevitan®) on the agrocenosis of winter wheat. The key objectives included assessing its impact on the restoration of benefi cial soil microbiota, stimulation of root system development, improvement of vegetative growth indicators, and the ability to retain productive soil moisture. Methods. Field research was conducted during 2024-2025 in the Bila Tserkva district of Kyiv region on typical chernozem soils. The object of study was winter wheat of the «Dzhersi» variety. The experiment included four treatments: control (no application); seed treatment with CR Trevitan® (100 ml/250 kg); surface spraying of soil with the preparation (0.5 L/ha); and combined application of both methods. CR Trevitan® is an organic complex containing humic and fulvic acids, as well as macro- and microelements. The effectiveness of the preparation was evaluated through the analysis of key biometric plant indicators (tillering, biomass, height), root system development, microbiological activity, and productive soil moisture content. Results. The application of CR Trevitan® demonstrated a signifi cant positive impact on all studied parameters compared to the control. The best results were achieved through the combined use of the preparation. Specifi cally, winter wheat tillering increased by 35%, and plant biomass at the tillering stage grew by 49% with surface spraying. Pre-sowing seed treatment led to a 7% increase in plant height. A signifi cant stimulation of root system development was also observed, which is critical for nutrient uptake and plant resilience. Furthermore, the preparation effectively promoted the restoration of benefi cial soil microfl ora and improved soil moisture retention, as confi rmed by relevant analyses. Conclusions. The study confi rmed the high effectiveness of the composite recultivant Trevitan® as a tool for the biologization of winter wheat cultivation. Its application comprehensively enhances growth and development conditions: it stimulates vegetative processes, intensifi es root development, restores biological soil activity, and optimizes the water regime. Thus, CR Trevitan® is a promising product for sustainable agriculture, capable of increasing yields and environmental safety, particularly under reduced use of mineral fertilizers and climate instability.
