Biofertilizers provide “Eco-friendly” organic agro- input. Biofertilizers such as Rhizobium, Azotobacter, Azospirillum and Blue green algae (BGA) have been in use a long time. Rhizobium inoculants is used for leguminous crops. Azotobacter can be used with crops like Wheat, Maize, Mustard, Cotton, Potato and other vegetable crops. Azospirillum inoculations are recommended mainly for Sorghumm, Millets, Maize, Sugarcane and Wheat. Blue green algae belonging to a general Cyanobacteria genus, Nostoc or Anabaena or Tolypothrix or Aulosira, fix atmospheric nitrogen and are used as inoculations for paddy crop grown both under upland and low land conditions. The present study was carried out to investigate Growth promoting effect and Biochemical character of Solanum melangena L. by treating Blue green algae.
