Abstract: Improper fertilization has become an essential factor limiting peanut yield and quality improvement. To improve peanut yield and quality, the effects of different fertilizer additives on peanut growth and yield were investigated. In this work, the effects of four fertilizer additives produced by microorganisms (CL, T6, T4, and P1) on peanut growth and yield were evaluated through pot and field trials. The results indicated that all fertilizer additives significantly increased the branch number and biomass of peanuts compared to the control. Additionally, T6 and CL treatments led to significantly higher peanut yields in the field. The aboveground nitrogen concentration of peanuts treated with CL and T6 was also significantly higher than that of the control, while T4 treatment did not show a significant difference. Overall, CL and T6 had the best positive effect on the growth of peanuts. The potential application values of CL and T6 in peanuts showed that fertilizer additives produced by microorganisms could be used as effective measures to achieve highly efficient production in agriculture.
