Seed priming was documented to effectively enhance crop performance with ultimate better yield under a wide range of environmental conditions. The current meta-analysis summarizes the findings of 2394 observations collected from 68 articles indexed on Web of Science database about the impact of different priming techniques on wheat yield under different forms of abiotic stress. Economic yield (EY), biological yield (BY), and thousand-kernel mass (TKM) were the yield parameters extracted from the analyzed articles. Heterogeneity test indicated high consistency of the collected observations. Analysis metrics revealed general enhancement of EY of stressed wheat plants by 29%, BY by 22%, and TKM by 16% due to seed priming. Under stress, redox halopriming caused the maximum enhancement in both EY and BY, while osmopriming caused the maximum enhancement in TKM. Moreover, seed priming …
