tailieunhanh - Characterization of Rhizosphere soils of foxtail millet and isolation of Azospirillum strains

A Total of 40 different foxtail millet roots samples along with rhizospheric soil were collected from Raichur and Koppal districts of Karnataka. Azospirillum strains were isolated and physic-chemical properties of the soil were analyzed. Among them, 20 samples each from Raichur and Koppal districts were collected. The physico-chemical properties of the soil and available nutrients of Raichur district samples ranged from, pH (), electrical conductivity ( dS m-1 ), organic carbon (), available nitrogen ( to kg ha-1 ), available phosphorus content ( to kg ha-1 ), available potassium ( to kg ha-1 ). Likely, the physico-chemical properties of the soil and available nutrients of Koppal district samples ranged from, pH (), electrical conductivity ( dS m-1 ), organic carbon (), available nitrogen ( to kg ha-1 ), available phosphorus content ( to kg ha-1 ), and available potassium ( to kg ha-1 ). Forty Azospirillum isolates were obtained by adopting enrichment culture technique. All the isolates formed subsurface pellicles in NFBTB medium including the reference strain. Pellicle was formed 1-2 mm from the surface of semisolid NFBTB medium. All the Azospirillum strains turned olive green colour of Bomothymol Blue (BTB) to brilliant blue. | Characterization of Rhizosphere soils of foxtail millet and isolation of Azospirillum strains
