Table 10.2 Examples of free-living plant growth promoting rhizobacteria tested on various crop types.
Bacteria Plant Conditions Results of addition of bacteria to plant Reference
Increased germination rate [5]
Xanthomonas maltophila Sunflower Laboratory and
greenhouse
[48]
Greenhouse Positive seedling growth response by all three
plant species to PGPR treatment, especially
tomato, where no exogenous mineral nutrients
were added
Early stimulation effect on seedlings
Enterobacter cloacae CAL3 Mungbean tomato,
pepper
[68]
Maize, wheat Field In wheat cultivars over seven seasons, increases
in yield from 15 to 30% and increases
of 50–60% in yield when fertilized
Over six seasons, maize yield increased from
15 to 25% and up to 40% with fertilization
Azospirillum local isolates
From Argentina
[72]
Pseudomonas chlororaphis 2E3, O6 Spring wheat field Laboratory Increased seedling emergence at two different
sites by 8–6%
Strong inhibition of Fusarium culmorum
No promotion effect of inoculated plants
evident in soils free of Fusarium infection
10.6 Applications of PGPRsj205
Pseudomonas fluorescens Mungbean, wheat Greenhouse Root and shoot elongation [76]
[94]
Mungbean Greenhouse Root and shoot elongation in presence of
CdCl2 and (CH3COO)2
Pseudomonas putida, Pb and
Cd resistant
