Abstract
The inoculation technology has resulted in obtaining high yields of soybean grains without the application of mineral nitrogen in Brazil. The evaluation of different inoculant formulations, especially in new areas, is important to improve the success of this technology. Consequently, the aim of this study was evaluate the effects of soybean inoculation with Bradyrhizobium in the peat and liquid carrier. Two field experiments were conducted in 2005 and 2006 using soybean (cultivar BRS Tracaja) seeds inoculated with peat or liquid inoculant, a control without inoculation, and another treatment with the application of 200 kg ha-1 of N. Thirty five days after the emergence of the plants the nodules number and dry weight, dry weight and Total N in aerial plant matter, and at the harvest, grains yield and N in the grains were evaluated. The peat inoculant provided high number of nodules and dry weight, while mineral nitrogen fertilizer provided the largest plant dry matter and total N; both of these treatments were significant superior relative to the control. The soybean seeds inoculation with Bradyrhizobium provided grains yield similar to mineral nitrogen fertilization with 200 kg ha-1 of N, independently of the inoculant carrier, thereby suggesting the efficiency of this technology for both formulations tested.
