Screening of rhizobial isolates from Vigna radiata for plant growth promoting traits
Abstract
In present study, native rhizobia isolated from root nodules of Vigna radiata grown in CCSHAU farm were evaluated for various plant growth promoting traits. A total of 65 isolates were retrieved and screened for plant growth promoting traits. The strain MRH 12 showed high IAA production, MRH 1 and MRH 12 showed the highest solubilization of phosphate and HCN production among others. MRH 1 and MRH 12 also showed tolerance to high temperature (45°C) and salt concentration (5%), which may be effective in soil with high salinity. The IAA, HCN production and phosphate solubilization shown by these isolates make them suitable for further trials.
