Drought is the main abiotic stress that severely reduces wheat yield across globe. To cope up this situation, use of organic amendments best option. Biochar an soil amendment used to improve carbon, contents, water holding capacity soil, enhance fertility and maintain desired soil. Present study was carried out under semi-arid climatic conditions mitigate adverse effects drought at critical growth stages i.e., tillering (DTS), flowering (DFS) grain filling stage (DGFS) by using three biochar treatments viz. B0 = Control, B1 27.88 g kg−1 B2 37.18 kg−1. Results revealed negatively affected attributes all stages, while, found most sensitive resulted severe reduction. However, application significantly mitigated detrimental improving number fertile tillers (19.50%), spike length (6.52%), grains per (3.07%), thousand weight (6.42%), biological (9.43%) economic (13.92%) as compared control treatment. Moreover, improved efficiency physiological stressed wheat. Principal component analysis linked different scales demonstrated potential physio-biochemical traits explain variations condition with response application. In crux, (37.18 kg−1) can be effective stratagem achieve through mitigating stress.
