Abstract
The aim of the present study was to assess the importance of siderophore producing rhizobacteria on the growth of Brassica juncea under chromium stress. Pseudomonas sp. (A4) produced an iron chelating substance siderophores in iron deficient medium. Under chromium stress condition Pseudomenas sp. (A4) markedly increased the root and shoot length and also biomass of Brassica juncea as compared to Pseudomonas sp. (A3). This plant growth promotion has been related to the microbial production of siderophores.
