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.

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.

Being One Of The Earliest Living Forms Originated On This Planet, Blue Green Algae (Cyanophytes/Cyanobacteria) Have Successfully Lived Through A Variety Of Environmental Abiotic Stresses, Such As Extreme Heat Of The Primitive Earth, Anaerobiosis Prevalent At The Time Of Their Origin To Subsequent Oxygeny For Which They Have Been Responsible. Over The Years They Have Adapted Themselves To Several Man-Made Stresses Like Various Types Of Industrial Effluents Of Different Chemical Make-Up, Chemical Fertilizers, Pesticides, Heavy Metals, Etc. For These Reasons They Are Considered As An Appropriate Model System For Studies Of Stress And Adaptive Responses. The Book Contains Information On Ecophysiological Responses Of Blue Green Algae In Habitats Polluted By Different Types Of Industrial Effluents, E.G. The Untreated Effluent Released From A Molasses Distillery, Sponge-Iron Industry And A Fertilizer Factory. Interaction Of Nitrogen Fixing Blue Green Algae In Rice Fields To Different Commercial Pesticides Has Also Been Described. The Blue Green Algal Forms Colonizing The Exposed Surface Of Archaeologically Important Temples And Monuments Of Various Regions Of India Is Given. Survival Strategies Of Blue Green Algal Species On The Exposed Rock Surfaces As Well As In The Crust On Dried Soils Of Rice Fields Under Temperature And Desiccation Stress Has Been Presented. Ecophysiology Of Thermal Blue Green Algae Has Also Been Described. It Would Serve As A Reference Book For Researchers In Universities And Research Institutions Working On Adaptation Of Plants And Microorganisms To Environmental Stresses And Also For Botany, Microbiology And Environmental Science Students At M.Sc. Level.

Nitrogen is the most limiting element for crop production. Traditionally, expensive commercial fertilizers are used to correct soil nitrogen deficiencies. Indeed, 50% of the increase in rice yields after World War II can be attributed to increased fertilizer nitrogen use. Although an increased rate of fertilizer nitrogen application has been advocated to meet the growing demand for food, it is unrealistic to advise the farmers to apply fertilizers they could hardly afford, and whose prices are likely to escalate in the years ahead. In addition, when they are not applied judiciously there are problems of environmental pollution as plants are capable of taking up only a relatively small portion of the applied nitrogen, a substantial amount being lost through various chemical and biological processes. The exploitation of cheaper alternatives or supplements to fertilizers have therefore gained much interest in recent years. Our increased interest in biological nitrogen fixation as a supplement or alternative to nitrogen fertilizers led to the convening of a consultants' meeting on `The Role of Isotopes in Studies on Nitrogen Fixation and Nitrogen Cycling by Blue-Green Algae and the Azolla-Anabaena azollae Association', in Vienna from 11--15 October 1982. The consultants' group recommended that the Joint FAI/IAEA Division of Nuclear Techniques in Food and Agriculture embark on a coordinated research programme in this field and that initial emphasis should be placed on Azolla-Anabaena symbiosis. As a result, such a programme was initiated in 1984, which was concluded in 1989. The results and conclusions reported here are those that were generated during the five years of its operation.
