بررسی اکولوژیکی ازتوباکتر در دو منطقه مرتعی آذربایجان و اثر تلقیح آن روی رشد و تغذیه معدنی گیاه گندم
A great number of studies have been conducted on the role of Azotobacter - a free living N2-fixer - in agricultural soils, but our information is lacking on the importance of Azotobacter in pasture soils. This research was conducted to study the relationship between ecological and edaphical factors with the population of the bacteria in soil. Soil samples were taken from two sites in Azarbaidja...
Azotobacter spp. are known for their ability to fix nitrogen into the soil non-symbiotically. Their activities can be enhanced through provision of optimum cultural conditions. Hence, this study aimed isolate and optimize growth (medium condtions) with a focus on pH, sucrose indole acetic acid (IAA) concentrations. The counts obtained from rhizosphere crops ranged 4.0 × 104 – 1.0 106 CFU/g. thr...
