Isolation and Characterization of Nodule Bacteria from Mungbean and Investigation Its to Drought Water Stress on Soybean Plant

Among the environmental stress factors the most widely limiting for crop production on a global basis is water. Water stress has been found to decrease productivity of most plant particularly soybean. The aims of the study are isolation and propagation of nodule bacteria from root of mungbean by using YEMA media, characterization of nodule bacteria by using YEMA + Congored and the investigation of drought water treatment. The result indicated that nodule bacteria from root of mungbean do not absorbs red colour on YEMA medium and the coloni white cloudy like milk and the form is spherical colonies with a convex surface. Characterization showed as Rhizobium sp. The investigation of drought water stress indicated that, there are significant difference on the treatment of 50 ml water/1000 g soil of drought water stress toward the growth i.e. plant hight, number of leaves and nodule formation on soybean plant.
