Various abiotic stresses are increasing environmental pressure due to the combined impacts of climate change, along with competitive use of land generating uncertainties about the capacity to grow sufficient food. Millets offer alternative solutions for food production during climate change. Barnyard millet is the fastest growing among the millets and is an important food source for fragile regions due to its quick growth, resistance to various abiotic stresses, and capacity to flourish in unfavourable conditions. This crop can be utilized as a model for stress tolerance in crop improvement or as a substitute crop in changing climatic conditions. ‘Omic’ approaches are pivotal in identifying novel genes and mechanisms responsible for abiotic stress tolerance, which can be leveraged to enhance the stress resilience of staple crops while maintaining yield. Integrating conventional farming methods with cutting-edge technologies can serve for the development of better stress-resilient crops that can help meet current food demands.
