Abstract: Inoculation of Blue-green algae-alagalizationrncommonly reported as a safe agro ecosystem to contribute in economicrnfeasibility in paddy habitat, minimise cost and energy inputs. Some ofrnadditional researches of algalization or BGA with soils carried out in Indiarnand, various other countries have shown advantageous effects on productivity.rnModern increasing trend of population is the only way to assuse productionrnpotential of agriculture adopting through improved agricultural practice andrnhigh yielding varieties of crops and use of fertilizers in agro fields with thernoptimum use of pesticides and other required materials. Algalization is beingrnfollowed in various states such as Haryana, Karnataka, Andhra Pradesh, Jammurn& Kashmir and Maharashtra. Algalization is also being utilized in UnitedrnStates of Soviet Republic, Philippines, Egypt, and China. BiotechnologyrnDepartment of Govt. of India has introduce four major centers in the growingrnareas of paddy fields of the country to accelerate and extension of work in thernfield of algal bio fertilizer in 1990. The programme was launched in Lukhnow (UP),rnCalcutta (West Bengal), Madurai (Tamil Nadu) and New Delhi under technologyrndevelopment and presentation programmes on Cyanobacterial biofertilizer withrnthe objective of i) to provide low cost locally used technology for largernproduction of BGA, ii) to isolate better and fast growing N2- fixingrnstrains, iii) to demonstrate the farmers in the field, iv) to develop starterrninoculums and v) to study both ecology and economy benefits. The result ofrnstudy of algal biofertlizer has been reported very useful for the formers ofrnsmall and marginalised group of India.
