Excessive irrigation of saline-alkaline soils with Cd-contaminated wastewater has resulted in deterioration both soil and plant quality. To an investigate this, a study was conducted to explore the effects biochar (applied at 10 t ha−1), PGPRs (Bradyrhizobium japonicum (USDA 110) + Trichoderma harzianum 1:1 ratio), Si-NPs (25 mg L−1) on soybean plants grown saline-alkali irrigated wastewater. The results showed that trio-combination PGPRs, (as amendments) foliar spraying), more effective than individual or coupled applications reducing Cd bioavailability soil, minimizing its absorption, translocation bioconcentration tissues. reduced by 39.1% accumulation roots, shoots, seeds 61.0%, 69.3%, 61.1%, respectively. Physiological improvements were also observed, including 197.8% increase root growth, 209.3% chlorophyll content, 297.4% carotenoid levels. significantly improved physicochemical characteristics, enhanced microbial indicators boosted enzymes activity, which turn facilitated nutrient uptake increased antioxidant activity. These positive outcomes photosynthesis, productivity seed nutritional value. Overall, are considered reliable approach not only for revitalizing growth but immobilizing improving health under irrigation.
