“Symbiotic nitrogen fixation has special significance from the point of view of sustainable agriculture, as it contributes towards a pollution free environment, which is the crying need of the hour due to the threat of impending climate change. Efforts on breeding for improved nitrogen fixation in grain legumes are an extremely rare subject. This book on ‘Breeding for Enhanced Nitrogen Fixation in Groundnut’ fulfills the long felt need in this important but hitherto neglected area. The book is a pioneering study on this rare subject and brings out strategic findings derived from authentic field studies conducted over several years in an international research institute. The book will not only be catering to the needs of researchers and policy makers but students of nitrogen fixation as well.” (jacket)
