The cells of Azospirillum remain in association with
the roots and fix part of the atmospheric nitrogen.
Azospirillum cultures are useful for the cereals and cash crops viz. Wheat,
Paddy, Bajra, Jowar, Maize, Mustard, Cotton, Cumin, Banana, Sugarcane, Tobacco,
Castor, Vegetables etc., as well as horticultural crops.
The effective strain used in Azotobacter culture fixes about 15 – 20 Kg.
atmospheric nitrogen per hectare.
Certain growth promoting substances released by these cultures are useful for
increasing the seed germination, plant growth and ultimately the yield.
In certain condition they also exhibit anti-fungal activities and thereby
fungal diseases may be controlled indirectly.
About 10 to 15% increase of crop yield can be achieved with the use of these
• Seed Treatment (for One Acre) : 250 Gms.
/ 10 Kg. Seeds
• Seedling Treatment (for One Acre) : 250 Gms.
250 Gms. / 1.0 Kg. / 25 Kg.
N. B. : In addition the same quantity of Phosphate
Solubilizing Bacteria are also recommended.
