Тhe qualitative and quantitative composition of extracts obtained from poplar wood waste (buds, leaves, bundles, twigs) generated from logging activities was investigated. Then, the effects of the poplar extract on the morphogenesis, physiological and biochemical parameters, and productivity of white cabbage plants were studied and were found to be significant. Thus, for the plants grown from seeds soaked in a 0.03% aqueous emulsion of the extract, the respiration rate was 2.7 mg CO2 per 1 g of dry matter, which is 540% higher in relation to control 1 (C1), and 270% in relation to control 2 (C2), and a higher yield was obtained compared to other treatment options. The respiration intensity and productivity of plants that received foliar feeding with a 0.003% aqueous emulsion of the extract also exceeded the corresponding indicators in the control samples. Thus, the respiration intensity in the initial growth phase of the rosette and roots was 1.9 mg CO2 per 1 g of dry matter, which is 380% in relation to control 1 (C1), and 190% in relation to control 2 (C2). The yield obtained was 1008 c/ha.
