This study evaluated whether biochar&#8211;biostimulant combinations could improve mungbean (Vigna radiata L.) performance under reduced NPK fertilization. A polytunnel pot experiment was conducted using a completely randomized 2&#8201;&#215;&#8201;4 factorial design with two NPK levels, 100% and 50% of the recommended dose, and four treatments: biochar alone, biochar&#8201;+&#8201;humic acid, biochar&#8201;+&#8201;Bacillus amyloliquefaciens, and biochar&#8201;+&#8201;Pseudomonas fluorescens. Biostimulant addition to biochar improved plant growth, pigment status, and antioxidant response, with the strongest responses observed under reduced NPK supply. Under 50% NPK, biochar&#8201;+&#8201;P. fluorescens increased grain yield by approximately 90% compared with biochar alone and maintained grain yield (4.00&amp;nbsp;g plant&#8315;&#185;) comparable to the 100% NPK biochar-only control (3.85&amp;nbsp;g plant&#8315;&#185;). It also enhanced nodulation, increased total chlorophyll by approximately 60%, and reduced malondialdehyde by approximately 50%. Grain weight was positively associated with nodule number and ascorbic acid content and negatively associated with H&#8322;O&#8322; content. These findings support biochar-assisted P. fluorescens supplementation as a promising strategy for sustaining mungbean productivity under reduced NPK input, warranting further field validation for broader applicability."}
