Main Data : In a study conducted during 1995-97, five species of cyanobacteria (Anabaena variabilis UU 147, Nostoc sp. UU 29130, Cylindrospermum sp. UU 245, Aulosira sp. 00 25118 and Caiothrix sp. 00 29139) from the 120 species of cyanobacterial germplasm of the rice fields in Orissa, India, maintained at Utkal University, were selected on the basis of their wide occurrence, faster growth, higher nitrogen fixing capability to find out their potentiality on the growth and yield of two different rice varieties (Mashuri and CR 1009). These organisms were cultivated outdoors in galvanized iron trays and polybags for producing inocula for field application. Increase in grain yield by over 25% than control was obtained in plots algalized with fresh cyanobacteria inoculum containing regional isolates which was much higher than the yield of the plots inoculated with soil based culture. Most of the inoculated species competed successfully with the indigenous flora and established in the rice fields.
