Linkages of Microbial Plant Growth Promoters Toward Profitable Farming

Soil and plant health are linked with each other, and both are badly affected by the excess application of inorganic fertilizers and pesticides. The negative impact of chemical fertilizers toward the environment forced the scientific community to find out an alternative strategy that can improve crop yield and quality in an eco-friendly manner. The modern agriculture system is well furnished with microbial inoculants and plant defense elicitors. However, the application of microbes to manage plant growth and fitness needs to improve. Microbial inoculants play an important role in soil mineralization, energy mobilization and channelization, and also nitrogen fixation. This chapter aims to review the microbial plant helpers and their interlinks toward plant and human health. Microbial inoculums improve crop quality and yield, plant and soil health, and profit to farmers and reduce pollution. Proper utilization of microbial inoculants could help to improve the economic condition of the farmers and the country.
