Abstract: A field experiment was conducted at Rajasthan College of Agriculture Udaipur, (MPUAT) (Rajasthan) during Summer season of 2016 to evaluate the effect of phosphorus and bio-inoculants on soil fertility and yield of Mungbean [Vigna radiata (L.) Wilczek] under factorial randomized block design with three replications and two factors likewise, four level of phosphorus Control (0 kg P2O5 ha-1) , 20, 40 and 60 kg P2O5 ha-1 and four level of bio-inoculants (control, PSB, Aspergillus awamori , PSB + Aspergillus awamori ) applied to the variety SML-668. The data were analyzed using standard statistical procedures. Results revealed that application of 40 kg P2O5 ha-1 significantly enhances number of total and effective nodules per plant flowering stage after 45 DAS, leaf area index, chlorophyll content, protein content in seed, as well as produces the higher net returns (62144 Rs /ha) and highest B:C ratio (3.86) which was statistically at par with 60 kg P2O5 /ha. Inoculation of mungbean seeds with PSB + Aspergillus awamori significantly increased number of total and effective nodules at flowering after 45 DAS, LAI, chlorophyll content, nutrient content, protein content in seed, and gave highest net return ₹63187 /ha as compared to control, PSB and Aspergillus awamori, whereas, B:C ratio of treatment PSB and Aspergillus awamori was highest 3.98 as compared to control.
