A field experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during kharif season of 2017 on loamy sand soil. The experiment was laid down in randomized block design with eleven phosphorus management treatments (Control, 100% RDF, 75% P through inorganic + 25% through FYM, 75% P through inorganic + 25% through VC, 75% P through inorganic + 25% through PM, 50% P through inorganic + 50% through FYM, 50% P through inorganic + 50% through VC, 50% P through inorganic + 50% through PM, 25% P through inorganic + 75% through FYM, 25% P through inorganic + 75% through VC, 25% P through inorganic + 75% through PM) and two treatments of microbial inoculation (uninoculated and seed inoculation with PSB). Results revealed that among phosphorus management treatments, application of 50% P through inorganic + 50% through VC significantly increased the growth characters and yield of groundnut viz., crop dry matter accumulation at most of the stages, number and weight of root nodules/plant, CGR and chlorophyll content over rest of the treatments. It also recorded the significantly highest pod yield (2198 kg/ha), haulm yield (3009 kg/ha) and biological yield (5207 kg/ha) of groundnut. However, it showed statistical equivalence with 50% P through inorganic + 50% through PM in most of the growth and yield of the crop. Results further indicated that inoculation of groundnut seed with PSB significantly enhanced the growth characters and yield over uninoculated control. Seed inoculation with PSB also improved to pod, haulm and biological yield of groundnut to the extent of 20.3, 12.4 and 15.7 per cent over control, respectively.
