Nitrogen fertilizers are crucial for enhancing agricultural production and ensuring food security. However, their inefficient use is often due to limitations inherent in crop plants and the formulation, application, and management of nitrogen fertilizers.

The primary objective of this book is to evaluate the different aspects of the nitrogen fertilizer's fate in relation to overall nitrogen inputs to agricultural systems. This assessment aims to improve nitrogen use efficiency and reduce negative environmental impacts.

Topics covered include the use of emerging technologies such as genetic enhancement and QTL mapping, understanding nitrogen's interactions with other nutrients, and mitigating nitrogen losses caused by environmental factors and management practices.

Nitrogen Use Efficiency in Plants bridges the gap between basic and applied research and practical crop production. The book addresses a wide range of topics related to nitrogen use efficiency and plant and crop responses to nitrogen applications through fertilizers, including nitrogen acquisition and reduction, molecular approaches, nitrate induction and signaling, and nitrogen use under abiotic stresses.

This book is an essential resource for academics and researchers working in plant physiology, biochemistry, biotechnology, molecular breeding, and agronomy. It provides a comprehensive, interdisciplinary description of the problems associated with the efficient use of nitrogen in agriculture.
