Summary<\/h2>\n

Paddy fields are globally important ecosystems providing food for majority of the world population. Soil N fertility is one of the most important factors to achieve higher rice productivity. However, excessive use of inorganic fertilizers has generated several environmental issues including surface and ground water pollution. Biofertilizers or use of inoculants of bacteria, algae and mychorrhizal fungi are promising alternatives mainly attributed to their biological N-fixing ability. Cyanobacteria (Blue Green algae) inhabit paddy soils and flood water as major N-fixing organisms. Although, use of Cyanobacteria as a biofertilizer has been initiated long ago, field applications are limited due to less success rates of inoculants in the field.<\/p>\n

For successful use of cyanobacteria as a biofertilizer in rice fields, an extensive knowledge of the indigenous cyanobacterial community is essential. Thus main objective of the current research is to explore the temporal variation of cyanobacteria with reference to the crop growth stage.<\/p>\n
