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.

Pyroligneous Acid Effects on Crop Yield and Soil Organic Matter in Agriculture—A Review

Agronomy, Journal Year: 2025, Volume and Issue: 15(4), P. 927 - 927

Published: April 10, 2025

Pyroligneous acid (PA) or wood vinegar, a co-product of biomass pyrolysis, is thought to be beneficial for plant productivity and soils, with the potential reduce otherwise harmful agrochemicals. Here, we review evidence use PA on growth soil health parameters. The analysis includes 65 peer-reviewed studies 171 (yield) 123 (plant biomass) data sets, covering 33 different crops belonging 6 groups. Significant positive, non-linear relationships between concentration, yield, were found at concentrations as low 0.1%, optimum around 0.5–1% overall positive effects up 6–11% (depending application type), but yield declines above these concentrations, suggesting herbicidal effects. Across whole set, increase by an average 21% 25%, respectively, 31% rate. effect most pronounced under sub-optimal conditions (salt, drought, pathogens), while responses did not differ Soil organic matter content shows small significant response application, amount very compared major shortcomings identified include inconsistent measures applied (amount composition) short duration experiments typically only 1–2 growing seasons, which prevents long-term Overall, results this encourage further research sustainable agriculture.
