Moreover, the plants grown under drought and salt stress condition showed significant higher activity of SOD than their control and this stress induced an increase of SOD activity was declined by application of P. putida H-2-3. Similarly, drought and salt stress caused a higher DPPH scavenging activity in soybean plants and P. putida H-2-3 involved to lower the DPPH scavenging activity in non-stressed and abiotic stressed plants
