Agricultural science takes a multi-disciplinary approach across disciplines of natural, economic and social sciences, to develop methodologies for understanding and advancing the practices of agriculture. Research in this field includes studies in plant breeding and genetics, soil science, pest-crop dynamics, weed-crop dynamics, entomology, among many others. Improving crop growth, selective breeding of drought-resistant crop and animal varieties, improved pesticides, etc. are also being studied in this discipline. This book highlights the recent studies in the field of agricultural science. It also provides a detailed explanation of the different concepts and applications of the modern agricultural practices developed in recent years. This book will be a resource guide for agronomists, agriculturists, agro-economists and agrobiologists, as well as students and experts working in this domain.
