Inoculation is the most important practices in soybean. The objective was to investigate the effect of different doses, forms (liquid and peat) and routes (seed and groove) application of Bradyrhizobium japonicum inoculant in two soybean cultivars (GMT 1188 RR 133 and RR TMG). The experimental design was randomized blocks (DBC) with four replications. The predominant experimental design was a factorial 8 x 2. The first factor was the inoculant treatments: control (pure seed); 200 kg N.ha-1 (urea), 200 and 800 mL.ha-1 liquid inoculant applied via direct spray in the planting furrow (200 mL and liq / groove and 800ml liq / groove); 200 and 800 ml of inoculant líquido.100 kg-1 seeds (200 mLliq / week and 800 ml Liq / wk); 100 and 400 g kg-1 of inoculant turfoso.50 seeds (100 g turf / week and 400 g tur / week). The other factor were two cultivars. The Bradyrhizobium japonicum does not change the soybean chlorophyll content in "first year" cultivation. Doses of 200 and 800 mL.ha-1 liq / groove are those which produce more nodes and grains. In "first year" The cultivar TMG 1188 RR is more productive that TMG 133 RR.
