Soil samples from various agro climatic zones of Andhra Pradesh, India were collected and screened for the isolation of effective microbes during 2009-10. Based on the efficacy and in vitro compatibility, nine microbial strains (Bacillus spp, Streptomyces spp, Azotobaacter spp and Frauteria spp) were identified and christened (VBT 01 to VBT 09). Each strain was evaluated for its plant growth promoting efficacy (PGP) in black gram (Vigna mungo (L.) Hepper) and its antagonistic activities against select pathogens. Pot culture studies recorded high percentage of seed germination (94.7%) when the black gram seeds were coated with VBT 09 as compared to untreated control (83.2%). Maximum radical length of 8.0 cm was recorded in VBT 09 as compared to control (0.53cm). PGP traits of all the strains such as Hydrogen cyanide (HCN), ammonia production and hydrolytic enzymes like cellulase, pecti.. View More»
