AbstractDrought is a persistent and complex natural vulnerability whose rate and extent of recurrence are expected to increase with climate change. Regardless of the progress made in responding and adapting to water scarcity, drought stress causes severe afflictions. Therefore, the present study has been accomplished in Department of Botany, University of Peshawar to investigate the effect of biochar and plant growth promoting rhizobacteria (PGPR) Cellulomonas pakistanensis (NCCP11) and Sphingobacterium pakistanensis (NCCP246) on Vicia faba under drought stress. Two varieties of seeds Desi (V1) and Pulista (V2) were obtained from Cereal Crop Research Institute (CCRI) Nowshera, sown in earthen pots in triplicate filled with 3 kg soil and sand (2:1) and biochar (0 and 5% w/w). Scanning electron microscopy of biochar showed porous nature and energy dispersive x‐ray spectroscopy spectroscopy showed C, Ca, Mg, and Na elemental composition. Germination parameters including germination energy (GE), Timson germination index (TGI), germination index (GI), and water use efficiency (WUE) were amplified to 28.04, 19.17, 25.72, and 43.62% in V1, respectively, and 14.38, 16.66, 19.79, and 41.50% in V2 respectively, by the co‐application of biochar and PGPR. Agronomical attributes including, fresh and dry weight of leaves, root, and shoot were significantly reduced, which were positively ameliorated by 28.57, 36.36, 16, 10.47, 14.28, and 10%, respectively, by the application of biochar and PGPR especially by NCCP246 in combination as well as individually. It has been concluded that, adversities of drought significantly condensed with the application of biochar and PGPR, which may be important in agricultural practices carried out in water‐deficient regions.
