Weed seed dormancy is a key adaptive trait that contributes to the persistence, spread, and management challenges of weeds in agroecosystems. This mini-review synthesizes current knowledge on the types and mechanisms of weed seed dormancy, including physical, physiological, and combinational forms, highlighting the hormonal regulation, structural barriers, and environmental cues involved in dormancy induction and release. The ecological implications of dormancy such as prolonged seedbank longevity, staggered emergence, and resistance to control measures are discussed in the context of crop weed interactions and management timing. Various dormancy-breaking and management strategies, including mechanical scarification, thermal and cold stratification, chemical priming (e.g., gibberellic acid, nitrate), biological degradation, and Integrated Weed Management (IWM), are evaluated for their efficacy and practical application. The review underscores the need for species-specific, climate-resilient approaches that integrate dormancy biology with predictive modeling and precision agriculture tools. By bridging fundamental dormancy mechanisms with field-scale control strategies, this review provides a foundation for more sustainable and targeted weed seedbank depletion practices.
