Phosphorus has an important role in plant nutrition and N2 fixation in legumes. The interactive effect of three phosphate solubilizing bacteria (PSB) and Bradyrhizobium japonicum on yield and N, P, K uptake and nodulation of soybean root (Glycin max L. CV. Harcor) was studied under greenhouse conditions. In greenhouse experiment treatments consisted of a factorial combination of four levels of PSB (without PSB M0 ,Pseudomonas putida M1 , Aeromonas hydrophila M2 , Pseudomonas fluorescens M3) and two levels of B.japonicum (without bacterium B0 and with bacterium B1) and three levels of P(P0 = 0 , P1=29, P2 = 58 mg triple superphosphate/Kg soil) in a randomized complete block design with four replications. At harvest, shoot dry weight, seed weight, nodule number, dry and fresh weight of nodules and concentrations of N, P, K in shoot dry matter were measured. PSB significantly increased shoot dry weight, N, P, K concentrations in shoot, fresh and dry weight and number of root nodules. B.japonicum had positive significant effect on these parameters as well as on seed weight. Dual inoculation of plants with PSB and B.japonicum had significant effect on shoot dry weight, P and N concentrations in shoot. Increasing phosphorus levels significantly increased plant dry weight, shoot P concentration and seed weight. Highest P concentration in shoot was obtained at P2 level but in plants inoculated with P.putida, dry weight at P1 level was not significantly different from P2 level. }, URL = {http://jstnar.iut.ac.ir/article-1-686-en.html}, eprint = {http://jstnar.iut.ac.ir/article-1-686-en.pdf}, journal = {Journal of Water and Soil Science}, doi = {}, year = {2007} }
