Abstract: A field experiment was carried out during the winter season of two consecutive years 2006-07 and 2007-08 to study the effect of six combinations of bio-fertilizers and two chemical fertilizers on onion (Pusa variety). The treatments were Azotobacter+PSB, Azotobacter+VAM, Azotobacter+Azospirillum, Azospirillum+PSB, Azospirrilum+VAM, PSB+VAM, NPK 100%, NPK 50% and Control. The height of the plant was maximum (40.43cm) with the application of Azotobacter+VAM. Number of leaves, number of inflorescence / plot and bulb diameter were maximum of Azotobacter+Azospirillum. Azotobacter+Azospirillum and NPK 100% gave maximum length of bulbs (6.23cm). The maximum number of scale per bulb (9.88) was counted from NPK 50%. Hence, it is concluded that Azotobacter+Azospirillum combination is the better for onion growth as compared to other combination of biofertilisers. Due to this, here the sustainability in production and environmental consideration are concerned.
