摘要

Drought stress severely threatens global crop productivity. This study investigated the synergistic potential of zinc ferrite nanoparticles (ZnFe₂O₄ NPs) and plant growth promoting rhizobacteria (PGPR) to ameliorate drought-induced damage in common bean (Phaseolus vulgaris L.). Under greenhouse conditions, plants were subjected to two drought durations (10 and 20 days) and treated with ZnFe₂O₄ NPs (100 mg L⁻¹) and PGPR. The combined application (ZnFe₂O₄ NPs + PGPR) exhibited pronounced synergistic effects, enhancing germination rate index by 39.7% and reducing mean germination time compared to control. Under drought, the combined treatment markedly improved vegetative morphology, increasing leaf area (38.4%), shoot length (76.5%), and root fresh weight (140%). Anatomically, it mitigated drought-induced epidermal impairment, promoting opened stomata (25.2% longer), enhanced guard cell dimensions (37.6% longer), and more developed trichomes (67.7% longer). Multivariate analyses confirmed strong positive associations among improved growth traits and distinct clustering of synergistic treatments. These findings demonstrate that co-application of ZnFe₂O₄ NPs and A. pakistanensis is a highly effective strategy for enhancing drought adaptation in P. vulgaris, offering a promising nano-biofortification approach for sustainable agriculture in water-limited environments.
