Readers will be informed about seeds, the science and technology associated with them. Seeds are fertilized mature ovules created through sexual reproduction in plants, and they are the least expensive and most crucial input in agriculture. It is estimated that high-quality seeds of improved varieties can lead to a 20-25% increase in yield. Seed technology is an interdisciplinary field that encompasses a range of activities, including variety development, evaluation, and release; seed development; seed processing; seed storage; seed testing; seed certification; seed quality control; and seed marketing. These activities aim to improve the genetic and physical characteristics of seeds. Each topic is discussed in a separate chapter, and this book will be highly beneficial to its readers.
