Cost effective pilot scale production of biofertilizer using <i>Rhizobium</i> and <i>Azotobacter</i>

Abstract

We standardized the protocol for pilot scale production of Rhizobium and Azotobacter biofertilizer technology using region specific and environmental stress compatible strains isolated from various agro climatic regions of Odisha, India. The cost benefit of biofertilizer production through a cottage industry is also presented. With an investment of $5000 as fixed cost, recurring expenses approximately $460 per year, indirect cost towards salary and wages $4800, 24000 packets of biofertilizer can be produced. By selling the biofertilizer $0.5 per pack, the net benefit is $6000 per year. If the production capacity is quadrupled, the profit would be about $30000 per year. This cost benefit calculation showed the possibility of entrepreneurship on microbial biofertilizers through cottage industry in rural areas in India as well as other developing countries.
