The study was conducted at the net house and the laboratory of the Department of Agricultural Chemistry, BAU, Mymensingh during the period from April, 2007 to August, 2007. Roots of rice seedlings cv. BR 26 were inoculated with PSB strains B1, B2 and B3 before transplanting in pots (30cmx30cm) containing acidic red soil of Madhupur (Clayey loam textured having pH 4.89) in Aus season. The experiment was laid out in Completely Randomized Design (CRD) with two factors viz. PSB inoculants {i.e. Inoculation without PSB strain (B0), with PSB strain {B1, B2 and B3} and different P fertilizer {without P fertilizer (P0), TSP (P1), SSP (P2)} and Rock phosphate at the recommended dose of P {i.e.P1, P2 and P3} with 3 replications in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh. N, P, K, S, and Zn were applied at per recommended dose (95 kg N, 12 kg P, 45 kg K, 8 kg S and 1 kg Zn ha-1) as urea, MOP, gypsum and zinc sulphate (ZnSO4), respectively. All nutrients, except N, were applied as broadcast and incorporated with soils prior to transplanting. N was applied in three splits. The first one-third was applied at final pot preparation and the second third one at rapid tillering stage (30 DAT) and before panicle initiation stage (60 DAT), respectively. Both of these installments were broadcast and incorporated with soil followed by weeding. Intercultural operations were done in the pot for ensuring and maintaining proper growth and development of the crop. After harvesting, the grain and straw samples of rice plant were oven dried were analyzed for total N, P, K, Ca, Mg, S, Fe, Zn, Mn and Cu contents following standard methods. Correlation- regression studies were also done to find out the statistical relationship between P content and N, K, Ca, Mg, S, Fe, Zn, Mn and Cu contents in grains and straw of rice cv. BR26.
