Biofertilizer is immobile, an unclear term. It can simply be established that biofertilizers are identified as plant extracts, composted municipal waste, and various microbial mixtures with unidentified components and chemical fertilizer formulations supplemented with organic compounds. Likewise, the scientific literature has a very open interpretation of the term biofertilizer, on behalf of everything from fertilizers to plant extracts. However, biofertilizer is more commonly indicated for the use of soil microorganisms to increase the availability and absorption of mineral nutrients by plants. Therefore, it is essential to define the term "biofertilizer". There is a scheme that defines a "biofertilizer" as a substance that contains living microorganisms that colonize the rhizosphere or the interior of the plant and promote growth by increasing the supply or availability of primary nutrients and / or growth stimuli for the target crop, when applied to seeds, plant surfaces or soil. If the existence of a microorganism increases plant growth by making nutrients more available or by replacing nutrients in the soil or by increasing the plant's access to nutrients, provided that the nutritional status of the plant has been improved. Plant For microorganisms, the material that is applied to the plant or soil that contains the microorganisms, can be characterized as biofertilizer .This definition separates biofertilizer from organic fertilizer that contains organic matter. Rhizobacterial isolates Bacillus aerophilus (King’s B-15/ Cor-20) was found effective for enhancing the coriander plant growth attributes as well as seed yield. There was significant effect of PGPR treatment on coriander crop yield and highest yield was found with Bacillus aerophilus (1374.5 kg/ha) and lowest yield was observed with control.
