Abstract:
Nitrogen (N) is one of the most crucial elements for plant development and productivity. Growing plants cannot utilise the approximately 78% of available atmospheric nitrogen because of its stable state. Biological nitrogen fixation (BNF), which has the potential to boost agricultural output and sustainability without compromising the environment or the health of the soil, is one of the potential biological alternatives for N-fertilizers. Plants may utilise ammonia, which is created when biological N fixation (BNF) converts atmospheric nitrogen into it. The use of N2-fixing actinobacteria as a bio-inoculant has shown to be one of the most efficient and ecologically friendly strategies to increase crop plant growth and output because nitrogen is a main limiting factor for plant growth. Actinobacteria that fix atmospheric nitrogen use a nitrogenase enzyme complex to do this (Kim and Rees, 1994).
