Agricultural Biostimulants for Mitigation of Salt, Drought, and Heat Stress provides up-to-date information on sustainable strategies to enhance the resilience of agricultural crops under adverse environmental conditions. As part of the Biostimulants and Protective Biochemical Agents series, this volume focuses on high-impact challenges and emerging opportunities in crop stress management.Biostimulants represent a promising and effective approach to achieving sustainable agriculture. Widely regarded as renewable sources of plant nutrients, they can enhance crop productivity and improve soil health. Over the past decade, there has been growing interest in the use of diverse biostimulants—including plant growth-promoting fungi, rhizobacteria, seaweed extracts, and organic amendments—to increase nutrient use efficiency and boost plant tolerance to abiotic stresses.This book covers a range of key biostimulant categories such as bacteria, algae, plant growth regulators (PGRs), plant growth-promoting bacteria (PGPB), biochar, and other core approaches. It explores how specific biostimulants contribute to protecting and enhancing plant health and is the first comprehensive reference to focus exclusively on their role in safeguarding crop yields under salt, drought, and heat stress conditions. - Highlights cost-effective and eco-friendly biostimulant technologies for the sustainable development of agricultural crops - Presents cross-disciplinary insights from agronomy, plant physiology, agricultural science, biotechnology, and molecular biology - Written by global experts with a focus on sustainable agriculture and climate-resilient crop production
