Title: Azotobacter as potential biofertilizer for agricultural exploitation
Abstract:
Pakistan is an agricultural country. Abiotic and biotic stresses lead to the poor germination of plants by spreading hindrance in the natural mechanism of plant growth and development. Among crop growth promoting rhizobacteria, gram negative Azotobacter proves to be a powerful candidate for improving the plant health. Several mechanisms carried out by Azotobacter include nitrogen fixation, phosphorous solubilization, pesticide and fungicide, production of siderophores and growth promoting hormones collectively contribute to the improved plant health. Moreover, Azotobacter applications of specific biofertilizers are also beneficial for soil health to make the soil fertile. Being the favorable and cost effective alternative to chemical fertilizer, the use of biofertilizers has been increased moreover, the microbial biofertilizer formulation on the commercial level is still a challenge to overcome. The inoculation of nitrogen fixing bacteria has advantage over traditional mineral fertilizers. The selected strains proved to be efficient nitrogen fixers. The strains is more sensitive to the temperature and pH as compared to the nutritional factors. The nitrogen fixer Azotobator strain also produced growth hormones and vitamins that play important role in better plant growth. Thus this approach could be reduce over application of chemical fertilizers for the profit of farmers and ensure environment-friendly practices. The present study aims to summarize the beneficial properties and effective research conducted on the use of Azotobacter biofertilizer for a sustainable agro ecosystem
Audience Take Away Notes :
- The knowledge shared in this paper will help to cut the overreliance on chemical fertilizer that caused the ecological imbalance that has adversely effected the environment and human health
- It can reduce the abiotic as well as biotic stress in crops
- Azotobacter based biofertiliser are comparatively economical, non-toxic and possess significant potential for effective administration of sustainable agriculture. Moreover, the Azotobacter spp. in fields can accelerate the beneficial biosynthesis of organic compounds
