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 sixteen treatments each replicate thrice whereas 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). The experiment results revealed that the growth parameters such as yield attributes viz., During 2019-20, maximum number of siliquae per plant in mustard (323.64), seeds per siliquae (15.83), length of siliquae (8.23 cm), test weight of mustard crop (5.06 g) was recorded, During the next year of study 2020-21, similar trend was observed and maximum number of siliquae per plant (367.30), seeds per siliquae (16.95), siliquae length (9.05 cm), test weight of mustard crop (5.06 g) significantly recorded in the treatment T₁₆. However, during the first year 2019-20, maximum biological yield (74.23 q/ha), seed yield (21.63 q/ha), stover yield of 52.63 q/ha, harvest index of 28.24 per cent, During the year 2020-21, Maximum biological yield (81.47 q/ha), seed yield (21.63 q/ha), stover yield (60.16 q/ha), harvest index (31.21 per cent) was recorded under the treatment T₁₆. During the year 2019-20, maximum gross income was obtained under the treatment T₁₆ (Rs. 129491/ha), net returns of Rs. 98031/ha, B: C ratio (3.1: 1) was achieved with treatment T₁₆ followed by treatments T₁₄. During the year 2020-21, maximum gross income was obtained under the treatment T16 (Rs. 143207/ha), net returns of Rs. 111747/ha, B: C ratio (3.6: 1) was achieved with treatment T16 (60 kg P₂O₅ ha^-1 + 60 kg Sulphur ha^-1 + Inoculation with PSB) among all treatments.
