An On- farm trial were conducted during Rabi season of 2015-16 and 2016-17 at farmers field on pre-selected seven locations in Muzaffarpur district of Bihar considering farmers as replication to assess the efficacy of bio-fertilizers on yield and economics of potato. The results revealed that nutrient management of biofertilizer has statistically significant impact on tuber yield and economics as well as soil fertility status. The highest tuber yield (22.65 and 23.50t ha-1) was obtained significant in the treatment N120-P72-K100 along with Azotobacter +PSB as compared to N150-P90-K100 (RDF) as well as farmers practice. The maximum net return (Rs. 65375.00 ha-1 and Rs.70250.00 ha-1) and B: C ratio (2.31 and 2.49) was found in N120-P72-K100 along with Azotobacter +PSB over N150-P90-K100 (RDF) and farmers practice. However,the seed treated with Azotobacter and PSB registered net positive balance of available nitrogen and phosphorus soil status over initial.
