Plant growth response to growth promoting rhizobacteria

Numerous species of soil bacteria flourish in the rhizosphere of plants, which may grow in, on, or around plant tissues and stimulate plant growth by a plethora of mechanisms. These bacteria are collectively known as plant growth promoting rhizobacteria (PGPR). Bacillus velezensis is a PGPR that promotes plant growth, enhances drought stress tolerance, and suppresses plant pathogens. However, little is known about the interactive effects of exogenous orange peel amendments and B. velezensis PGPR strains on plants growth and productivity. The project aims to (i) identify elite strains of B. velezensis for plant growth promotion, (ii) evaluate the best mode of application of B. velezensis PGPR strains amended with orange peel powder to enhance plant growth and physiological parameters. We will also test the effect of the growth promoting rhizobacteria on seed viability, germinability and seedling vigor and establishment. The test plant will be kale.
