A field experiment was conducted during kharif 1992 and 1993 at Raigarh, Madhya Pradesh, to determine the optimum phosphorus level for groundnuts with and without Rhizobium inoculation of seeds. Application of P2O5 significantly increased the number of pods per plant, pod and haulm yield during both the years, while shelling percentage and 100-seed weight were significantly increased only during the first year. All the yield attributes and yield increased significantly up to 60 kg P2O5 ha-1. On average, 60 kg P2O5 ha-1 produced 17.72% and 58.97% higher yield than 30 kg P2O5 ha-1 and controls, respectively. Rhizobium inoculation increased yield by an average of 8.23% compared with controls.
