Abstract
A field experiment was conducted for two consecutive years to assess the efficiency of bio-fertilizers at two fertility levels on yield and economy of potato crop. Results revealed that application 100% recommended dose of nitrogen and phosphorus + Azotobacter and Phosphobacteria gave the maximum tuber yield which was closely followed by application of 75% recommended dose of nitrogen and phosphorus + Azotobacter and Phosphobacteria. However, both the treatments gave considerable net return indicating 25% saving of nitrogen and phosphorus fertilizers. Among both the inoculants Bacillus cereus was found better than Bacillus subtillis in potato yield.
