This book explores how diazotrophic plant growth-promoting microorganisms (DPGPMs) can support sustainable agriculture. These beneficial microbes help plants grow by naturally fixing nitrogen from the air, reducing the need for chemical fertilizers and improving soil health. The chapters cover a wide range of topics. Early chapters explain the role of endophytic and free-living diazotrophs in crops like sugarcane and their molecular mechanisms for promoting plant growth. Several chapters focus on how these microbes can be used as biofertilizers and how they help plants cope with environmental stress. The book also discusses the use of nanotechnology to improve nitrogen use efficiency and the potential of microbial solutions to address climate change. Later chapters explore recent advances in nitrogen fixation, including its application in non-leguminous crops and the use of synthetic biology. This book is a valuable resource for students, researchers, and professionals in agriculture, microbiology, and environmental sciences. It is also useful for policymakers and practitioners interested in eco-friendly farming practices and sustainable food production.
