Advances in the Application of Plant Growth-Promoting Rhizobacteria in Horticulture

To manage a soil biodiversity, significant role is played by microbes. In this context, free-living soil bacteria/rhizobacteria are beneficial for improving plant growth and development commonly termed as plant growth-promoting rhizobacteria (PGPR). Uses of efficient microbes inhabit the roots forming colonies in higher plants acting as a pipeline for nutrient supply and provide many beneficial compounds competent for boosting plant growth and development. PGPR are well-known plant growth promoter (PGP) native of rhizosphere, which is a substantial soil ecological, environmental and plant wellness for soil-plant-microbe interaction. Keeping in mind the above points, it was felt that they are very useful in horticultural plants. For that, this book chapter encompasses the works of various scientists/students/researchers and reviewed their work for the awareness and use of PGPR in horticultural crops.
