The study of crop development, growth and yield falls under the domain of agricultural science. It focuses on ways to increase crop yield through the right use of fertilizers and pesticides. A good crop production management system addresses both crop production optimization and environmental sustainability. Research in crop science involves developing strategies for improving cultivars, crop yield, disease resistance and climate resilience. The field also uses tools of biotechnology and genetic engineering in order to alter the genetic traits of crops and to produce a better quality yield. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of crop development, growth and yield. It provides a comprehensive understanding of modern theories and advanced concepts of this field. This book will serve as a reference to a broad spectrum of readers.
