Megjegyzések:	In the context of increasing agricultural challenges posed by soil salinity and drought stress,the main importance of the present study was to evaluate some novel treatments for improvingcanola productivity and resilience by applying wood distillate (WD) in combination with bagasseash (SBA). A two-year field experiment using a split plot design was conducted and evaluatedseveral physiological and biochemical parameters under different irrigation regimes conducted at80% and 50% field capacity. While there were considerable moderation effects of SBA and WD on soilsalinity, expressed as exchangeable sodium percentage (ESP), under both well-irrigated and droughtconditions, more importantly, the ESP was reduced to 31% under drought stress with combinedWD and SBA applications over any single factor. WD and SBA treatments of canola leaves showedreduced Na content with increased K levels, and the plants maintained physiological attributes-chlorophyll content, stomatal conductance, and relative water content-to the level of controls ofwell-irrigation. Besides, they significantly alleviated oxidative stress by decreasing the hydrogenperoxide (H2O2), malondialdehyde (MDA), and electrolyte leakage (EL) levels and increasing theactivities of antioxidant enzymes like superoxide dismutase (SOD) and ascorbate peroxidase (APX).Nonenzymatic antioxidants such as total soluble sugars (TSS), total soluble proteins (TSP), totalphenolic content (TPC), and total flavonoid content (TFC) were significantly increased under stressconditions with a special accent on combined treatment, whereas the levels of proline and GB thatincreased in alignment with drought reduced under the combined application. Various growthparameters of plants like plant height, number of branches, and siliques per plant were significantlyimproved with WD and SBA under drought stress. Principal component analysis (PCA) and Pearsoncorrelation further confirmed the relationships among these parameters and thus underpinned thatWD and SBA can evoke a synergistic effect to enhance growth promotion and stress tolerance in canola.This, therefore, infers that the combined application of WD and SBA can be key, offering very highpotential as viable options to better canola productivity under adverse environmental conditions
