Comparative Study of Plant Growth Promoters on Vegetative Soil and Slit Soil

Soil is the biologically active porous medium that has developed in the uppermost layer of Earth’s crust. Free-living soil bacteria beneficial to plant growth, usually referred to as plant growth promoting rhizobacteria (PGPR), are capable of promoting the plant growth by colonizing the plant root. PGPR are also termed plant health promoting rhizobacteria (PHPR). Free-living nitrogen-fixing bacteria or associative nitrogen fixers example bacteria that belongs to the species Azospirillum, Enterobacter, Klebsiella and Pseudomonas, have been shown to attach to the root and efficiently colonize of root surfaces. The aim of this study is the potential of PGPB to enhance use efficiency of agro environmental resources.
