This study investigates the economic returns of lentil (Lens culinaris Medikus) by the use of phosphorus and biofertilizers [Rhizobium and plant growth promoting rhizobacteria (PGPR)] in Indian Punjab. The field experiments were conducted during Rabi 2013-14 and 2014-15 with combinations of four levels of phosphorus (0, 20, 30 and 40 kg P2O5 ha-1) and two/four biofertilizer treatments [uninoculated control and Rhizobium (LLR 12) + PGPR (RB 2)] in 2013-14, and uninoculated control, Rhizobium, PGPR and Rhizobium + PGPR in 2014-15) by replicating thrice. The use of 40 kg P2O5 ha-1 provided the highest gross returns whereas net returns and B:C were highest at 30 kg P2O5 ha-1. The combination of Rhizobium + PGPR + 40 kg P2O5 ha-1 provided the highest gross returns (Rs. 45902) whereas Rhizobium + PGPR+ 20 kg P2O5 ha-1 provided the highest net returns (Rs 20620). Furthermore, the integrated use of Rhizobium + PGPR + 20 kg P2O5 ha-1 provided higher net returns (Rs 20620) and B:C (1.88) as compared to sole application of 40 kg P2O5 ha-1 (Rs 18792 and 1.72). Thus, there was a net saving of 20 kg P2O5 ha-1 with the use of Rhizobium + PGPR inoculation without sacrificing the economics returns.
