Field experiment was performed to evaluate the effect of Oscillatoria annae extract on the morphology, biochemistry and yield of Oryza sativa. The results showed that 0.01% of cyanobacterial extract treatment significantly increased the growth and biochemical parameters in addition to the yield. Micro and macro nutrient analysis of the soil showed a positive correlation between reduction of nutrients and increase in morphological and biochemical parameters. The cyanobacterial growth promoting hormones moderately induced higher uptake of nutrients which resulted in increase of biochemical parameters in Oryza sativa. This study reveals that Oscillatoria annae intracellular products may satisfy the search for an efficient biofertilizer by producing IAA like plant growth regulators.
