Abstract:
An experiment was conducted to isolate and identify the Azotobacter spp. from different soil habitats of Latur district Maharashta and to study its effect on seed germination and growth patterns in green gram crop and it was found that, Azotobacter sp. was a free living bacterium in natural soil habitats and can be isolated easily on Azotobacter specific Ashby’s Agar media. In all three isolates of Azotobacter vinelandii were isolated and identified from the soil collected of different habitats. A pot experiment was formulated to study effect of Azotobacter seed treatment on seed germination and growth parameters of green gram. The results revealed that the seed bacterization with all the three isolates of Azotobacter vinelandii was responsible to increase seed germination, speed of seed emergence, seedling vigour index, plant height and numbers of branches per plant in green gram crop.
