Biological Nitrogen Fixation. 5. Application of Vermiculture Biotechnology. 6. Composting of Agricultural and Industrial Wastes. 7. Weed Management in Organic Farming. 8. Pest Management in Organic Famring. 9. Crop Residue Management. 10. Integrated Nutrient Management towards Sustainable Agriculture. 11. Integrated Farming Systems. 12. Case Studies. This book makes an attempt to present the available information on organic agriculture in a cogent and easily understandable manner. Though it is not exhaustive, which it is not meant to be, it is felt that book will a give an overview on the subject to the interested reader. A viewpoint on organic agriculture has been presented in the book, based on the experience of the authors. The book contains chapters on organic manures (including green manures), recycling of organic wastes, vermiculture, biofertilizers, organic methods of pest and weed management, integrated nutrient management, farming systems and case studies of organic farming. Selected literature is presented for further reading. A compilation of the available information has been a felt need of students, teachers, research workers and administrators in agriculture.

In its broader sense it includes crop ecology crop production crop nutrition soil fertility water management weed control seed technology etc. To be a good agronomist one needs to have a sound knowledge of all these agronomic aspects and also some related aspects from other sciences. Rice continues to be the most important food source in the world with about 20% of the global population depending on it as a staple food. A compilation of available information on rice has been a felt need of students teachers research workers and administrators in agronomy. This book is aimed at providing a comprehensive text on rice cultivation/production with major emphasis on rice based integrated farming system models organic farming aspects alternate cropping new technologies like SRI role of biotechnology etc. in an easily understandable manner. This book will help to enrich the knowledge of young researchers in various fields of agriculture and in particular agronomy as well as to the teachers and researchers of the Agricultural Universities/Research Organisations. 668 pp.…
