Groundnut (Arachis hypogaea L.) is an important oilseed crop cultivated worldwide. The present study was conducted to evaluate the effect of biofertilizers and phosphorus on the growth and yield of groundnut. A field experiment was conducted using a randomized complete block design with four replications. The treatments included different combinations of biofertilizers (Rhizobium and Phosphorus solubilizing bacteria and VAM) and phosphorus levels (30, 45, and 60 kg P₂O₅ ha/1). The results indicated that the application of biofertilizers and phosphorus significantly influenced the growth and yield parameters of groundnut. The combined application of Rhizobium along with VAM and 60 kg P₂O₅ ha/1 significantly increased plant height, number of branches per plant, number of pods per plant, pod yield, and oil content compared to the control. These findings suggest that the integrated use of biofertilizers and phosphorus can enhance the growth and yield of groundnut, thereby improving its productivity and economic returns for farmers. The result reported the application of Rhizobium along with VAM and Phosphorus 60 kg/ha recorded maximum plant height (58.39 cm), maximum dry weight (38.46 g/plant), nodules per plant (46.56), number of pod per plant (28.87), seed index (38.81), kernel yield (2.47 t/ha), haulm yield (2.97) were recorded in (treatment – 9) that is with Rhizobium + VAM + Phosphorus 60 kg/ha.
