Abiotic stresses such as drought, heat, salinity, and heavy metal contamination severely affect global agricultural productivity.Between 2005 2015, droughts caused losses of approximately USD 29 billion in developing countries, from 2008 to 2018, accounted for over 34% crop livestock yield losses, totaling about 37 billion.To support the growing human population, output must increase substantially, necessitating a 60%-100% rise productivity meet escalating demand.To address environmental challenges, organic, inorganic, microbial biostimulants are increasingly employed enhance plant resilience through various morphological, physiological, biochemical modifications.Plant under abiotic stress mechanisms abscisic acid signaling modulation, which regulates stomatal closure reduce water loss during drought heat stress.Additionally, they aid scavenging reactive oxygen species stabilizing ion channels, mitigating oxidative damage, maintaining ionic balance conditions salinity.This review summarizes recent advancements applying these biostimulants, focusing on their roles triggering biochemical, molecular changes that collectively conditions.It also includes bibliometric analysis all articles published 2019 2024 explores future research directions.Emphasis was placed optimizing biostimulant formulations understanding synergistic effects maximize efficacy conditions.By integrating into practices, we can adopt sustainable strategy safeguard face climate change stressors.
