Abstract

Pot experiments were conducted to evaluate the potentiality of Azolla and Blue Green Algae as biofertilizers for rice productivity. Blue Green Algae inoculation increased grain yield by 15% and straw yield by11%, Azolla showed increment by 26% in grain yield and by 20% in straw yield. Azollaand Blue Green Algae showed considerable increased in the N-content of soil, grain and straw. Azolla double incorporation was found more effective than other methods of application.
