Abstract :
Cyanobacteria, also known as blue-green algae, first appeared extremely early in the development of life and share many traits with both higher plants and gliding bacteria. Because of their great degree of substrate flexibility and ability to perform both transpiration and nitrogen fixation, cyanobacteria are widely distributed.Additionally, cyanobacteria have a special ability to boost production in a range of ecological and agricultural contexts. There have been reports of cyanobacteria growing both above and below the surface in a variety of soil types.They are frequently also distinctive characteristics of various sub-aerial environments, including numerous sporadically moist ones like rice fields. The majority of paddy soils naturally contain cyanobacteria, which may be a free source of nitrogen fixation. Cyanobacteria can absorb ammonia as ammonium (NH4) through a particular absorption method or by passive diffusion. Biofertilizers are inexpensive, easily controllable, self-replicating, and environmentally friendly inputs that enhance and expand crop nutrient availability. Biofertilizers increase the soil vitality. Rhizobium is a nitrogen-fixing biofertilizer for legumes, while Azotobacter, the bacteria Azospirillum, Blue Green Algae (also called BGA or cyanobacteria biofertilizer), and Azolla are used for cereals. Rhizobacteria, among others, provide an environmentally beneficial method for sustainable farming methods. When administered in tiny amounts, biostimulants— compounds derived from organic matter—can encourage a range of crops to grow and thrive.In both ideal and stressful environmental situations. Crop production rose as a result of agriculture.
