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.

Rice fields provide an ideal environment for harbouring Cyanobacteria (blue-green algae). A number of reports are now available to indicate a wide distributional spectrum of these organisoms under different soil and agroclimatic conditions. There is enough evidence that these rice fields cyanobacteria are capable of atmospheric nitrogen fixation in considerably large quantities and to some extent the organic matters. Thus the role of nitrogen fixing Cyanobacteria in the maintenance of the rice field soil fertility has been well sustained and documented. There is now positive evidence for the nitrogen fixing ability of more than 100 species of Cyanobacteria. During growth, Cyanobacteria liberate relatively large quantities of combined nitrogen mainly in the form of polypeptides with lesser amounts of free amino acids. Vitamins and auxin live substance. Approximately 40 to 50% of the algal nitrogen has been found to be recovered by the rice crop. These observations indicate the efficiency of these organisoms as a biological nitrogen source in a rice field ecosystem. In this book, a comprehensive floristic account on the rice field Cyanobacterial studies were attempted. In addition this book also offers an extensive discussion on isolation and cultural techniques and application in various fields. Contents Chapter 1: Biology of Blue-Green Algae (Cyanobacteria); Chapter 2: Isolation, Purification and Cultivation of Blue-Green Algae; Chapter 3: Taxonomic Enumeration of Rice-Fields Blue-Green Algae; Chapter 4: Importance of Blue-Green Algae.

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.
