A field experiment was conducted during kharif season of 2015 on loamy sand soil at the Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) which consisted of four levels of phosphorus (Control, 20, 40 and 60 kg P2O5 ha-1) and four levels of biofertilizers (Control, PSB, Aspergillus awamori and PSB + Aspergillus awamori) thereby, making sixteen treatment combinations and replicated thrice. The results indicated that application of phosphorus upto 40 kg P2O5 ha-1 recorded significantly highest organic carbon, available nitrogen, available potassium, dehydrogenase enzyme activity and alkaline phosphatase activity in soil after harvest which was at par with 60 kg P2O5 ha-1. Available phosphorus status of soil was recorded significantly maximum with the application of 60 kg P2O5 ha-1. Results further indicated that seed inoculation with the PSB and Aspergillus awamori significantly increased organic carbon, available nitrogen, available potassium, dehydrogenase enzyme activity and alkaline phosphatase activity in soil after harvest over the rest of the treatments.
