The effect of phosphorus, sulphur and seed inoculation by PSB on yield of mustard [Brassica juncea (L.)].

The experiment was laid out at the agriculture research farm of Bhagwant University, Ajmer, Rajasthan during the years 2019-20 and 2020-21. The experimental site lies 25.0112° N, 75.9139° E at an elevation of 271 meters above msl. The site was levelled having good irrigation facilities. The collected data were analyzed using Spilt Polt Design (SPD) design with three replications. There are 3 treatment combinationLevel of phosphorus, Level of Sulphur and Level of PSB (Phosphate Solubilizing Bacteria) with 16 treatments. Themaximum no. of siliquae per plant, no. of seed per siliqua, length of sliliqua (cm), test weight (g/1000 seeds), biological yield (q ha^-1), stover yield (q ha^-1) and harvest index (%)was recorded treatment T₁₆ (60 kg P₂O₅ ha^-1 + 60 kg Sulphur ha^-1 + Inoculation with PSB). This treatment was closely followed by treatment T₁₄ and T₁₅ and theminimum no. of siliquae per plant, no. of seed per siliqua, length of sliliqua (cm), test weight (g/1000 seeds), biological yield (q ha^-1), stover yield (q ha^-1) and harvest index (%) during both the years of the study (2019-2020 and 2020-21), respectively, were recorded under the treatment T₁ (RDF (N constant) + 40 Kg Sulphur ha^-1 + No Inoculation).The data were analysed to find out the significant treatments Panse and Sukhatme (1985).
