Abstract:

Rhizobial strains have contributed to enhance nitrogen fixation thereby soil fertility and yield of legumes crops when they are inoculated to seeds with sufficient quantity. Therefore a field experiment was conducted at Jimma Agricultural Research Center (JARC) to determine appropriate rate of Bradyrhizobium japonicum strains on nodulation and seed yield of soybean in south western Ethiopia during 2017/18 main cropping season. Six rates of strains (125, 250, 500, 625, 750 and 900 gm ha-1), one control (un-inoculated) and one 18 kgha-1 N were used. The experiment was designed in a randomized complete block design (RCBD) replicated three times giving a total of 24 plots. Nodulation parameters (nodule number and dry nodule weight,) was highly (P
