biostudies-literatureUnknown16Kaundal S<h4>Background</h4>Tomato production is often limited by poor soil health and nutrient deficits, which lower agricultural productivity. Plant growth-promoting rhizobacteria (PGPR) provide a sustainable approach to improve plant development and soil fertility.<h4>Objectives</h4>The objectives of this study were to 1) isolate and screen PGPR from the rhizosphere soil of tomato-growing regions in Himachal Pradesh, India; 2) evaluate the selected PGPR for biofilm production; 3) characterize and molecularly identify the biofilm-producing isolates; and 4) assess their efficacy in enhancing tomato plant growth.<h4>Methods</h4>Forty bacterial isolates were collected from soils in Dharon Ki Dhar, Shillai, Balh, and Berthin and tested for PGPR characteristics.
