Plant Growth Promoting Rhizobacteria (PGPR), a microbial biostimulant has been widely studied to stimulate plant growth through induction of natural biological processes. However, lack successful validation under open field remains barrier mark their standard in agriculture. Therefore, the aim research was highlight potential PGPR biostimulants via vitro studies and subsequently demonstrate pla...
