<p>The global population is projected to reach 8–10 billion by 2050, presenting significant challenges to agriculture in terms of maintaining food security and crop productivity due to adverse environmental conditions. Crop performance can be threatened by various abiotic stresses, such as temperature, drought, nutrient, and biotic stresses, such as pests and diseases. To address this, there is a need to develop strategies through which crop productivity can be improved, including the introduction of biostimulants into crop management practices at the beginning of the growing season, thereby reducing crop stress and helping retain yield and profitability. Potassium silicate is one such biostimulant. It is a widely recognized biostimulant in agriculture and has garnered significant attention owing to its multifaceted role in alleviating crop stress and enhancing overall plant health. This alleviates the negative impact of various stresses by maintaining effective stomatal conductance, enhancing CO₂ fixation, and thickening the cell wall. In recent years, there has been a growing interest in the use of potassium silicate (K₂SiO₃) as a potential solution to mitigate crop stress and enhance plant resilience. The market is currently witnessing an increase in demand because of its multifaceted applications. The current market size is approximately 450 thousand tons, and is expected to increase to 580 thousand tons by 2035, with a compound annual growth rate (CAGR) of 3.07%. This review article investigates the efficacy of potassium silicate in alleviating biotic and abiotic stresses in crops. Thematic analysis was utilized to synthesize the findings, revealing a diverse range of stresses mitigated by potassium silicate, including drought, salinity, heat, disease, and pest infestations. Several limitations and challenges have been identified, including variations in application methods, dosage, and environmental factors that may influence the efficacy of K₂SiO₃ in different crops. Despite these challenges, this review underscores the potential of potassium silicate as a sustainable solution for crop stress management, and offers insights for future research and agricultural practices.</p> Graphical Abstract <p></p>
