Field experiment was conducted on niger cv. Utkal Niger 150 (ONS-150) at Regional Research and Technology Transfer Station (OUAT), Semiliguda, Koraput, Odisha during kharif season for three years (2008-10) under rainfed condition to find out the effect of bio-fertilizers and green manuring integrated with chemical fertilizers on growth and yield of niger. Results revealed that application of 75% recommended dose of fertilizer integrated with Azotobacter and phosphorus solubilizing bacteria (PSB) recorded the highest seed yield of 405 kg/ha with net monetary return of ` 4083/ha and B:C ratio of 1.50 followed by recommended dose of fertilizer alone 386 kg/ha with net monetary return of ` 3650/ha and B:C ratio of 1.45. Application of 50% recommended dose of fertilizer + Azotobacter + PSB recorded seed yield of 370 kg/ha with net monetary return of ` 3313/ha and B:C ratio of 1.42.
