Abstract
In the present study a bacteria was isolated from agricultural soil near Ahmednagar, Mahatrashtra and identified as Rhizomonas species by morphological and biochemical tests. It was further tested for plant growth promoting activities like indole acetic acid production, hydrogen cyanide production, ammonia production, nitrogen fixation. The bacteria were able to produce indole acetic acid, hydrogen cyanide and ammonia. It was also able to grow on nitrogen free media, which indicated that it can fix atmospheric nitrogen. The effect isolate on wheat plant was tested by pot assay and data was analyzed by student t test. The P values for mean shoot length and mean root length were 0.00428 and 0.00688 respectively. The isolate significantly increased root and shoot length of wheat plant.
