Brassica crop species and their allies (Raphanus, Sinapis, Eruca, etc.) are important sources of edible roots, stems, leaves, buds and inflorescences, as well as of edible or industrial oils, condiments and forage. Many well known names of plants or plant products, such as kale, cabbage, brocolli, cauliflower, Brussels sprouts, kohl-rabi, Chinese cabbage, turnip, rape, rutabaga, swede, colza or rapeseed, canola, mustard, rocket, etc. are directly associated to this botanical group. The scientific interest for this botanical group has run parallel to its economical importance, and research achievements in our days would have certainly appeared unimaginable only two decades ago. As the end of the millenium approaches, entirely new fields (transformation, somatic fusion, etc.) have been added to the classical ones. Thus, nobody can doubt the opportuneness of this book, which combines and presents both the basic and applied biological aspects of the Brassica species.

This book is an outcome of the keynote/lead papers presented by the experts from different disciplines in the Indian Ecological Society International Conference 2016 on “Natural Resource Management: Ecological Perspectives”, organized at the Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, India. The book captures the essence of natural resource management from the intra and interdisciplinary perspectives of agricultural sciences (entomology, plant pathology, plant breeding and genetics, agronomy and soil sciences), social sciences (resource economics, agricultural extension education), medical sciences, and environmental sciences to stimulate discussion on the ecological perspectives of natural resource management. Wide-ranging topics on land and water resources, biodiversity, integrated farming system, role of microbes in agriculture, climate change and its impact on human health and crop pests, exploiting chemical ecology for pest management, human disease-causing pesticides, beneficial insects like lac insects, integrated pest management, resistance management in insect pests and Bt cotton , and diffusion and adoption of ecologically sustainable technologies at individual and organizational level are covered in the book.. The book will serve the professionals, researchers, academia, government, industry and students.
