Peanut plants can obtain N from N2 fixation via symbiosis with rhizobia, and inoculation with selected strains can improve grain yields. The aim of this work is to conduct field trials to compare single inoculation with Bradyrhizobium sp., Anabaena circinalis, and A. variabilis with dual inoculation during the 2021 and 2022 seasons in order to verify whether microbial inoculants may enhance peanut performance, growth, and grain yield as a result of their advantageous effects. The findings demonstrated that T8 treatment (dual inoculation with Bradyrhizobium sp, A. circinalis and A. variabilis and (1:1:1) + 25% N + 100% PK), generally improved peanut plant growth, resulting in significantly higher chlorophylls (mg g-1 FW), carotenoids (µg g-1 FW), number of nodules and dry weight of nodules (mg plant-1). In addition, improved soil fertility by increasing dehydrogenase and CO2 evolution, in the peanut rhizosphere during the two growing seasons. On the other hand, the percentages of N, P, and K in peanut plant leaves were affected by various inoculations in ways that were statistically significant (P ≤ 0.05), which were arranged by T8 > T6 > T7 > T5 for dual inoculation treatments and T2 > T4 > T3 > T1 for single inoculation treatments. The same pattern was observed for microelements (Fe, Cu, Mn and Zn). This was reflected in the yield (plant height, pod number, pod weight, yield, and 100-weight seeds), and the quality of the grain (percentage of oil, carbohydrates and protein).
