Abstract

A study was conducted to evaluate the effect of molybdenum and pre-inoculation of Azospirillum on biological nitrogen fixation, yield and yield contributing characters of soybean plants. A total of eight treatments were used in this study including control, 1.0 kg of Mo/ha, 1.5 kg of Mo/ha, 10.0 kg of Mo/ha, Azospirillum brasilense, A. brasilense + 1.0 kg of Mo/ha, A. brasilense + 1.5 kg of Mo/ha and A.brasilense + 10.0 kg of Mo/ha. The result showed that the bacterial inoculation in combination with 1.0 kg Mo/ha significantly contributed to increase weight of nodules (9.8 mg), plant dry weight (68.8 g), total nitrogen content (6%), 100 seed weight (13.2 g) and pod weight (47.5 g). Application of 1.0 kg of Mo/ha in association with A. brasilense produced significantly high yield (27.3 g/plant) compared to control which produced only 8.1 g/plant, thus indicating the potential of this treatment to be used for soybean in large scale.
