Phosphate solubilizing bacteria: Assessment of their effect on growth promotion and phosphorous uptake of mung bean (Vigna radiata [L.] R. Wilczek)
The aim of this work was to isolate phosphate solubilizing bacteria (PSB) and assess their effect on the growth of mung bean (Vigna radiata [L.] R. Wilczek) plants. Of 31 isolated PSB strains, two efficient strains, identified as Pantoea agglomerans (PSB-1) and Burkholderia anthina...
