Laser irradiation represents a promising approach for pre-sowing seed treatment in agricultural plants. This energy-efficient and environmentally friendly technology can enhance germination rates, reduce seed contamination, and improve plant vigor. This article presents the results of a germination experiment on barley seeds irradiated with lasers at wavelengths of 637 nm (red spectrum) and 360 nm (ultraviolet), using exposure durations of 10, 20, and 30 seconds at a beam power density of 6 J/cm².

The article presents the results of laboratory studies on the effect of biopreparations Humate 7+, Growth Matrix, Ecorost, Azotovite and Phosphatovite on the sowing qualities and growth parameters of terrestrial and underground plant organs of the winter wheat variety Nemchinovskaya 57. The work revealed the stimulating effect of the studied biological compounds on the initial growth processes of seedlings. A significant growth-stimulating effect on root system development was observed. The excess in the root length compared to the control was 0.7–21.0 mm (102–145%).
