A study was carried out during 2019-20 at Agriculture research station, Ummedganj, Kota under Agriculture University, Kota, to assess the effect of phosphorus (P0, P20, P30 and P40), liquid biofertilizer (No seed inoculation and Seed inoculation with Biophos) and growth regulator (control, 75 and 100 ppm Salicylic acid) on growth and quality parameters of summer mungbean [Vigna radiata (L.) Wilczek]”. Among phosphorus levels, P30 recorded significantly higher growth parameters viz., Plant height, Dry matter accumulation, Branches/plant, Nodules/plant, nodule dry weight, yields and quality parameters viz., N and P content and their uptake, protein content and protein yield as compare to control and P20. Seed inoculation with biophos recorded significantly higher growth, yields and quality parameters as compare to no seed inoculation. Spray of 75 ppm SA, being at par with 100 ppm SA and recorded significantly higher growth, yields and quality parameters as compare to control.
