Abstract

A pot experiment was conducted in the net-house of the Department of Soil Science, Bangladesh Agricultural University, Mymensingh during January to May, 2007 to investigate the effects of six selected Bradyrhizobium strains and urea-N on the growth and yield of soybean. There were eight treatments such as To: control, Ti: Urea @ 40 kg N had, T2: BAU 101, T3: BAU 107, T4: BAU 118, T5: BAU 145, Ts: BAU 150 and T7: TAL 102. The experiment was laid out in a Completely Randomized Design (CRD) having four replications. Phosphorus, potassium and sulphur were applied as basal dose from TSP, MOP and gypsum @ 40 kg P ha-1, 60 kg K ha-1 and 15 kg S had, respectively. Bradyrhizobium inoculation significantly increased the nodule number, nodule dry weight, root weight, shoot weight, N content and N uptake by plant at 33, 60 and 98 days after sowing over uninoculated control. Bradyrhizobium inoculation also significantly increased pod and seed number per plant, 100- seed weight, grain and stover yield of soybean over control. The effects of the strain BAU 107 was found most promising in growing soybean crop.
