The experiment was undertaken during Kharif 2019, 2020 and 2021 at Agricultural Research Station, S.D. Agricultural University, Aseda, Gujarat. The treatments comprised of four levels of phosphorus (P0 : Control, P1 : 20, P2 : 30 and P3 : 40 Kg P2O5/ha) and four levels of biofertilizers (B0 : Control, B1 : PSB, B2 : VAM and B3 : PSB + VAM. The experiment was laid out in a factorial randomized block design with three replications. Among the different levels of phosphorus, it seems that as levels of phosphorus increase (0 to 40 kg P2O5/ha), the value of seed yield and straw yield increases significantly over controls. In case of different bio fertilizers application significantly higher value of were recorded under the combined application of PSB + VAM compared to the control (no. application of bio fertilizers). The result of interaction found superior combination of 40 P2O5 kg/ha along with VAM and PSB bio fertilizers application and remained at par with the with 40 P2O5 kg/ha along with PSB bio fertilizers. Highest net return (Rs 30572/ha) and benefit cost ratio (1.89) were recorded under 40 kg P2O5/ha along with combined application of PSB + VAM
