"Enhancing Nutrient Use Efficiency: Concepts, Methods, and Management Interventions for Crops and Cropping Systems" is a comprehensive and extensive book that covers various topics related to improving the efficiency of nutrient use in various crops and cropping systems. Nutrient use efficiency refers to the ability of plants to utilize available mineral nutrients to produce economic yields. Although it is largely dependent on the plants' capacity to absorb nutrients from the soil, management practices play a crucial role in enhancing efficiency. This book delves into the different approaches that can be used to improve nutrient use efficiency. It is designed to provide valuable insights to scientists, farmers, students, and policymakers on holistic approaches to nutrient use efficiency in major crops and cropping systems. Improving nutrient use efficiency is essential for reducing production costs in the face of rising agricultural input costs and minimizing environmental contamination.

Soil physical management is a critical strategy for enhancing nutrient use efficiency. Farmers widely use handheld devices for nitrogen management in rice in several regions, and slow-release nitrogenous fertilizers are also popular. Long-term fertilizer experiments and Soil Test Crop Response Correlation provide valuable information on nutrient dynamics in the soil, which can be used to develop practices that enhance nutrient use efficiency. In addition to describing the concepts and methods of nutrient use efficiency, the book also covers management practices for various crops and cropping systems, including dryland crops, cereal-based cropping systems, rainfed pulses, soybean-based cropping systems, sugarcane-based cropping systems, cotton-based cropping systems, tobacco and oilseed-based cropping systems, rapeseed-mustard-based cropping systems, and spices-based cropping systems. This comprehensive resource guide can be used to enhance nutrient use efficiency in various crops and cropping systems.
