(Azospirillum Bio-fertilizer & comes in liquid based only)

 

It belongs to bacteria and is known to fix the considerable quantity of nitrogen in the range of 20-40 kg N/ha in the rhizosphere in non-leguminous plants such as cereals, millets, Oilseeds, cotton etc. The efficiency ofAzospirillium as a Bio-Fertilizer has increased because of its ability of inducing abundant roots in several pants like rice, millets and oilseeds even in upland conditions. Considerable quantity of nitrogen fertilizer up to 25-30 % can be saved by the use of Azospirillum inoculant. The genus Azospirillum has three species viz., A. lipoferum, A. brasilense and A. amazonense. These species have been commercially exploited for the use as nitrogen supplying Bio-Fertilizers.

 

One of the characteristics of Azospirillum is its ability to reduce nitrate and denitrify. Both A. lipoferum, and A. brasilense may comprise of strains which can actively or weakly denitrify or reduce nitrate to nitrite and therefore, for inoculation preparation, it is necessary to select strains which do not possess these characteristics.Azospirllium lipoferum present in the roots of some of tropical forage grasses uch as Digitaria, Panicum, Brachiaria, Maize, Sorghum, Wheat and Rye.
