Chitosan, a natural biopolymer derived from chitin, has become a significant factor in contemporary agriculture, providing potential avenues for improving crop yield in response to environmental stresses. Chitosan’s distinctive characteristics enable plants to exhibit enhanced resistance against abiotic stressors, including drought, salinity, heat, and heavy metal toxicity, as well as biotic hazards such as pests and diseases. Chitosan nanoparticles (NPs) have garnered significant interest due to their capacity to stimulate plant defense mechanisms and enhance stress tolerance. The incorporation of these NPs into plant systems enhances the bioavailability and absorption efficiency of chitosan, resulting in more potent and resilient responses to stresses. Moreover, the sustainable and environmentally friendly characteristics of chitosan make it a compelling option for decreasing dependence on chemical fertilizers and pesticides, aligning with the increasing demand for more eco-friendly agricultural practices. Given the escalating uncertainties posed by climate change and resource constraints, chitosan emerges as a valuable tool for enhancing crop health, productivity, and general resilience in global agricultural systems. This chapter emphasizes the significance of chitosan in shaping a more environmentally sustainable future for agriculture, providing a natural and efficient solution to the increasing demands of global food production.
