The cells of azotobacter remain free in soil or in vicinity of the root system and fix part of the atmospheric nitrogen.

azotobacter 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.

advantages

• 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 cultures.

dose

• seed treatment (for one acre) : 250 gms. / 10 kg. Seeds
• seedling treatment (for one acre) : 250 gms

packing
250 gms. / 1. 0 kg. / 25 kg.

Most of the cultivable soil being alkaline in nature contains less available phosphorus. Due to higher concentration of Calcium, whenever phosphatic fertilizers are applied in such soil, the large quantity of it gets fixed as Tri-Calcium Phosphate as it is water insoluble and hence becomes unavailable to the crop. Certain soil microorganisms have inherent capacity to dissolve part of the fixed phosphorus and make it available to the crop by secreting certain organic acids.

Phosphate Solubilizing Bacteria are useful for all the crops i.e. Cereals, Cash crops. Leguminous crops. Horticultural crops. Vegetables etc.

Advantages

• The effective strain of Phosphate Solubilized Bacteria used, increase the level of available P₂O₅ in the soil.
• With the increase in available P₂O₅ level, overall plant growth can be increased.
• 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 this culture.

Dose

• Seed Treatment (for One Acre) : 250 Gms. / 10 Kg. Seeds
• Seedling Treatment (for One Acre) : 250 Gms.

The rhizobium culture strains are antigenically very selective and require particular host or nodulation. The surface antigen on the rhizobial cells recognizes the binding sites (specific root exudates) on the roots of the leguminous plants. This characteristic makes them host-specific. Specific rhizobial cell can penetrate the roots of the specific leguminous plants only and form nodules. They multiply within the nodule using the carbon source from the plant and in turn fix part of the atmospheric nitrogen to the plant.

gsfc is producing different rhizobium cultures for the different leguminous crops as under: s groundnut, gram, pigeonpea, beans, cowpea, urad, mung, pea, soybean, lucerne etc.

each rhizobium culture is useful only for the crop mentioned on the packet. This culture should be applied by seed treatment only.

advantages

• the effective strain used in sardar rhizobium culture increases the healthy nodulation and thereby nitrogen fixation (about 40 to 50 kg. Per hactare).
• about 10 to 15% increase of crop yield can be achieved with the use of this culture.
• the residues of pulses (legume crops) left in the soil after harvesting the crop are also advantageous to the subsequent crops to be sown.

dose

• seed treatment (for one acre) : 250 gms. / 10 kg. Seeds
• seedling treatment (for one acre) : 250 gms.
