Fig 5. Total phenolic and flavonoid contents, and half maximal effective concentration (EC₅₀) of different activities.

Estimation of phenolic (TPC) and flavonoid (TFC) contents, and half maximal effective concentration of different activities (total antioxidant and scavenging–DPPH, H₂O₂ and OH⁻and reducing) in peanut plants grown under nitrogen supplement (C) or nitrogen deficit (N) conditions with inoculum (C+ and N+) or without inoculum (C–and N‒). Bars represent means ± SE, and ‘*’, ‘**’ and ‘***’ Indicate significant differences at P < 0.05, P < 0.01 and P < 0.001, respectively, while ‘ns’ means no significant difference.
