Book Description
The production of rice has increased considerably in recent years due to the release of improved varieties and the adoption of better fertilization practices. Nevertheless, the production and use of inorganic N fertilizer involves costly investments in terms of energy and transport, the need for complex manufacturing plants, as well as the potential for environmental pollution. The use of agricultural systems that include dinitrogen fixing organisms appears to be an economically sound cultural practice. In the particular case of rice, biological nitrogen fixation by Azolla, blue-green algae (BGA), and heterotrophic microorganisms has long been recognized, in southeast Asia, as a fertilizer for rice culture. The Azolla-Anabaena association has the unique property of being able to retain a significant amount of nitrogenase activity in the presence of combined nitrogen, making the system compatible with inorganic nitrogen fertilization. Researchers working with Azolla (N fixation) are dispersed in 2 countries of southeast Asia, Africa, Europe and Latin America, making it difficult to share ideas, concepts and research results on a more personal basis. Considering the potential positive impact of growing rice in association with Azolla, and the lack, to date, of an international gathering of scientists dedicated to Azolla research, the First International Workshop on "Practical Applications of Azolla for Rice Production" was organized by the University of Puerto Rico-Mayaguez Campus.

Book Description
Biological nitrogen fixation (BNF) has become important in rice farming systems because this process diminishes the need for expensive chemical fertilizers which have been associated with numerous health and environmental problems. The extensive exploitation of BNF would provide economic benefits to small farmers, avoiding all malign influences of chemical fertilizers. Meanwhile, advances in biotechnology have brought rice genetics to the threshold of new opportunities for increasing rice production. This volume focuses, in six different sessions, on the role of BNF in the improvement of rice production in the light of the current state of the art of BNF technology transfer and diffusion. New ideas on BNF technology in research, extension information and inoculant technology are also included, together with the socio-economic impacts of using BNF in rice farm systems.

Book Description
This book entitled Azolla Biofertilizer for Sustainable Rice Production contains the valuable informations from the vast experiences of the authors Professor Dr S Kannaiyan and Dr K Kumar in the field of Azolla-Anabaena symbiosis for the past 25 years. It is written with the objective of providing basic knowledge and practical technologies on the effective utilization of Azolla as an ecofriendly and economically viable biofertilizer for sustainable rice production. It gives an access to the latest informations on the biology of Azolla, growth, sporulation, N2 fixation, ammonia assimilation and mineralization process in rice ecosystem. It offers a good deal of practical technologies for maximum exploitation of the potential status of Azolla biofertilizer viz., mass production techniques of fresh biomass, sporocarp inoculum, carrier based immobilized cyanobacterial inoculant, field application and methods for enhancing N use efficiency of this technology. It also covers the utilty of Azolla as supplemental animal feed and the economics of usage of Azolla as biofertilizer for rice. Illustrative colour photographs have been included in various chapters for easy understanding of the subject by readers. This book will be very useful for the scientists, researchers, postgraduate students, extension workers and voluntary organizations involved in the crop management technology for sustainable rice production.
