Abstract

Certain soil microorganisms during solubilizing low soluble phosphate by production of organic acids or siderophores, may also increase, availability of some MICRONUTRIENTs. The interactive effects of three PHOSPHATE SOLUBILIZING BACTERIA (PSB) species and BRADYRHIZOBIUM JAPONICUM on yield and P, Fe, Mn, Cu, and Zn uptake of SOYBEAN (Glycin max L. CV Harcor) was studied under greenhouse conditions. In the greenhouse experiment treatments consisted of a factorial combination of four levels of PSB (without PSB Mo and three PSB species with relative high potential of solubilizing M1, M2, M3), two levels of Bradyrhizobium (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 and concentrations of P, Fe, Mn, Cu, and Zn in shoot dry matter were measured. PSB increased dry weight. P, Fe, Cu, and Zn concentrations (156%, 30%, 9.3%, 8.3, 6%) compared to the control. Bradyrhizobium had positive significant effect on these variables and also on seed weight. Dual inoculation of plants with PSB and Bradyrhizobium had significant effect on shoot dry weight, P. and Fe concentrations. Increment of PHOSPHORUS levels caused increase in dry weight. P concentration, seed weight (14%, 15%, 22%) and decrease in Zn concentration (5.5%) of plant compared to the control. Highest P concentration in plant obtained at P2 level but plant dry weight at P2 level had no significant difference with plants inoculated with PSB at P1 level. Therefore based on decrease in fertilizer applications, it could be concluded that P fertilizer application requirement for soybcan decreases about 50% with bacterium.
