A field experiment was conducted during rainy seasons of 2013-14 and 2014-15 at the Rajola Research Farm, Faculty of Agricultural Sciences, Department of NRM, Mahatma Gandhi Chitrakoot Gramodaya Vishwa Vidyalaya, Chitrakoot -Satna, Madhya Pradesh, India to study the effect of phosphorus levels in combination with biofertilizers on root nodulation of pigeonpea Cajanus cajan L.) Variety UPAS-120. Application of phosphorus up to P90 resulted in maximum root nodules (11.64 plant -1 ), fresh and dry
