Abstract

Inoculation of Blue-green algae-alagalization commonly reported as a safe agro ecosystem to contribute in economic feasibility in paddy habitat, minimise cost and energy inputs. Some of additional researches of algalization or BGA with soils carried out in India and, various other countries have shown advantageous effects on productivity. Modern increasing trend of population is the only way to assuse production potential of agriculture adopting through improved agricultural practice and high yielding varieties of crops and use of fertilizers in agro fields with the optimum use of pesticides and other required materials. Algalization is being followed in various states such as Haryana, Karnataka, Andhra Pradesh, Jammu & Kashmir and Maharashtra. Algalization is also being utilized in United States of Soviet Republic, Philippines, Egypt, and China. Biotechnology Department of Govt. of India has introduce four major centers in the growing areas of paddy fields of the country to accelerate and extension of work in the field of algal bio fertilizer in 1990. The programme was launched in Lukhnow (UP), Calcutta (West Bengal), Madurai (Tamil Nadu) and New Delhi under technology development and presentation programmes on Cyanobacterial biofertilizer with the objective of i) to provide low cost locally used technology for large production of BGA, ii) to isolate better and fast growing N2-fixing strains, iii) to demonstrate the farmers in the field, iv) to develop starter inoculums and v) to study both ecology and economy benefits. The result of study of algal biofertlizer has been reported very useful for the formers of small and marginalised group of India.
