A pot experiment was conducted to investigate the influence of phosphate-solubilizing bacteria on nutrient uptake by mung bean (Vigna radiata L.) at different Si levels in a saline soil. The combined application of PSB and Si significantly affected mung bean nutrient uptake. Applying phosphate-solubilizing bacteria (PSB) and silicon significantly improved post-harvest soil nutrient status in saline condition. Enhanced nutrient cycling facilitated by PSB, increased the bioavailability of phosphorus, while silicon mitigated the adverse effects of salinity, contributing to better nutrient retention. The soils exhibited improved nutrient content, organic matter stability. This integrated approach highlights the potential of PSB and silicon in promoting sustainable agricultural practices in saline soils. Phosphorus uptake increased 12 times for T8 (PSB+Si800) compared to the control. Nitrogen, potassium, and sulfur uptake increased to 3.75 times for T6 (PSB+Si300), 1.13 times for T7 (Si600) and 5.7 times for T8 (PSB+Si600), respectively, compared to the control. Hence a positive influence was observed in the nutrient (N, P, K, S and Fe) uptake by mung bean due to the application of higher Si doses with PSB. So, it can be concluded that higher doses of Si (600 mg/kg) with PSB could have improved the nutrient uptake and soil nutrient status in a saline soil.
