Abstract: A field experiment was carried out at Agronomy Instructional Farm, School of Agricultural Sciences, Career Point University, Kota, Rajasthan during Rabi season of 2019-20 and 2020-21 to Studies on the Effect of Phosphorus, Sulphur and PSB on Mustard [Brassica juncea (L.)] growth, Yield and Quality. The experiment was laid out in Split plot design with four levels of phosphorus (RDF-N constant, 20 kg, 40 kg, 60 kg) and two levels of sulphur (40 kg, 60 kg) and phosphate solubilizing bacteria (control and inoculation) with three replications. The experiment results revealed that the growth parameters such as plant height (154.66, 199.61), fresh weight of shoots(127.28, 189.15), Dry weight of shoots(16.46, 24.56), Number of green leaves per plant(17.79, 20.82), number of branches per plant(23.29, 26.81) maximum was recorded under the treatment T4 (RDF (N constant) + 60 Kg Sulphur ha-1 + PSB Inoculation). However, it was at par recorded under treatments T15 (60 kg P2O5 ha-1 + 40 kg Sulphur ha-1 + Inoculation with PSB), at 60 days and 75 days after sowing in 2019-20 and same treatments shows tremendous result in 2020-21. During the year 2019-20 and 2020-21 earliest 50 per cent flowering (52.63, 55.82 days) was observed and Minimum days taken to maturity were recorded (102.72, 106.03) in the treatment T4 (RDF (N constant) + 60 Kg Sulphur ha-1 + PSB Inoculation) which was statistically at par with treatment T12 (40 kg P2O5 ha-1 + 60 kg Sulphur ha-1 + Inoculation with PSB). Treatment T4 was statistically significant especially when compared to treatments where no inoculation with PSB was done.
