The practical manual “Recent Trends on Crop Growth and Productivity” is designed to serve as a comprehensive guide for students, researchers, and practitioners in agricultural sciences. It presents systematic procedures, analytical methods, and field-based approaches to assess and enhance crop growth and productivity under changing agro-climatic conditions. The manual integrates classical agronomic principles with modern tools, such as precision farming, remote sensing, and data-driven analysis. It provides practical insights into crop growth measurement, yield analysis, water and nutrient use efficiency, and sustainable management practices. Each exercise is supported by clear objectives, step-by-step procedures, observation formats, and interpretation guidelines to facilitate hands-on learning. This book is especially useful for undergraduate and post-graduate students of Agronomy, Crop Physiology, and related disciplines, as well as researchers engaged in productivity enhancement and sustainability studies. Extension personnel, field technicians, and policy planners will also find it valuable for understanding the dynamics of modern crop production systems. By combining scientific rigor with practical applicability, the manual aims to build technical competence and promote innovation in achieving higher and more sustainable crop productivity.
