Sweet basil (Ocimum basilicum L.), a widely valued medicinal and aromatic plant, is particularly vulnerable to drought stress, which negatively impacts its growth, marketable yield, and essential oil content. In commercial basil production, drought stress significantly limits biomass accumulation and disrupts the biosynthesis of secondary metabolites. Biostimulants and phytohormones have emerged as promising tools to enhance the resilience of sweet basil plants to drought stress. Among them, silicon (Si), salicylic acid (SA), gibberellic acid (GA3), and methyl jasmonate (MeJA) have individually demonstrated the ability to mitigate drought-induced damage by improving plant growth, physiological responses, and yield. This investigation aimed at evaluating the combined effects of Si either with SA, GA3, or MeJA in improving drought resilience in sweet basil.
