Chapter 1: In this chapter, we have provided a review on the components of rhizosphere engineering and the potential use of PGPR and its challenges to serve as an efficient component for sustainable agriculture.

Chapter 2: In this chapter, we isolated 35 different strains of a PGPR, Pseudmonas fluorescens and characterized various plant growth promoting traits such as production of ammonia, protease, Indole acitic acid (IAA), 1-aminocyclopropane-1-carboxylate deaminase (ACC) deaminase, ammonia, hydrogen cyanide (HCN), and souliblization of zinc and phosphate.

Chapter 3: In this chapter, we tested the influence of plant beneficial soil microbe, P. fluorescens, on the growth and development of sunn hemp (Crotalaria juncea L., Fabaceae) and sorghum (Sorghum bicolor L., Moench).

Chapter 4: In this chapter, we went through the major challenges in application of PGPR and importance of advanced technologies such as meta-proteomics, nanotechnology, and rhizosphere engineering to produce an effective and eco-friendly PGPR.
