Abstract:

Plant diseases have a major adverse effect on the crop yield and these can controlled by the biological approach by using PGPRs. Mustard crop suffers due to the increased number of abiotic and biotic stressors which affects its growth and yield. Now a day’s PGPR are being widely used worldwide, due to their eco-friendly nature and is considered as traditional agricultural technique. Keeping in view theabove problem, the present study has been conducted to explore the biocontrol agents along with their Plant Growth Promoting activities. A total of 300 bacterial strains were isolated from the rhizospheric soil of mustard crop. Further, twenty five bacterial strains were identified as salt tolerant rhizobacterial strains in 10% of NaCl supplemented Nutrient Agar Media. Only eight bacterial strains B1, B3, B9, B10, B11, B1, B14, B17 and B22 were found promising for their antagonistic activity against Alternaria brassicae plant pathogen. The percentage of inhibition varied from 31% to 42% under in-vitro condition. These bacterial strains were tested for other traits like HCN, Siderophore and Amylase production. Results showed that all the eight bacterial strains produced HCN, ranging from 20% to 60%. Out of eight bacterial strains, six bacterial strains showed potentiality for siderophore production ranging from 28% to 63% and five produced amylase ranging from 20% to 60%.
