Abstract The experiment entitled “Effect of Phosphorus, Sulphur and PSB on Yield, Quality and Nutrient Uptake of Mustard [Brassica juncea (L.)] on Haplustepts was conducted at Agronomy Farm, Krishi Vigyan Kendra, Chittorgarh (Rajasthan) during Rabi season, 2012-13 and 2013-14. The treatment consisted of four phosphorus levels (0, 30, 40 and 50 kg P2O5 ha-1) and four sulphur levels (0, 30, 40 and 50 kg S ha-1) and two levels of biofertilizers (with and without PSB inoculation) thereby making thirty two treatment combinations. The experiment was laid out in factorial randomized block design. The thirty two treatment combinations were replicated three times. The result revealed that application of 50 kg P2O5 ha-1 recorded higher plant height by 7.68, 16.10 and 17.45 per cent at 60 DAS and 4.74, 13.51 and 15.28 per cent at harvest over control, 30 and 40 kg P2O5 ha-1, respectively on pooled basis. Application of 40 kg P2O5 ha-1 significantly recorded dry matter accumulation 1.12 at 30 DAS, 23.10 at 60 DAS, 57.10 at 90 DAS and 70.15 g plant-1 at harvest stage, which represented significant increase over all preceding P levels on pooled basis. Significantly higher number of branches plant -1, number of siliquae plant-1, number of seed siliqua-1, test weight (24.86, 21.99, 366.35, 16.43 and 5.73 g) were obtain with 40 kg P2O5 ha-1 which were 27.35, 6.59, 1.23 and 7.70 per cent more than control. Significant higher seed, straw and biological yields were produced by 40 kg P2O5 ha-1 which represented 30.68, 31.76 and 31.46 per cent increase over control (14.83, 37.23 and 52.06 q ha-1, respectively). Protein content and its yield were also significantly enhanced upto 50 kg P2O5 ha-1 which tended 36.90 and 6.58 per cent over control (16.91 % and 251.71 kg ha-1) and oil content and its yield were also significantly enhanced upto 40 kg P2O5 ha-1 which tended 1.25 and 32.33 per cent over control (39.01 % and 579.33 kg ha-1), respectively. Application of phosphorus upto 40 kg P2O5 ha-1 showed progressive and significantly increased P, K, S, and Mn content in plant of mustard at flowering stage, except Zn and Cu content in which registered significant upto 40 kg P2O5 ha-1 and content of nutrient N and Fe content in which registered significant up to 50 kg P2O5 ha-1. Application of phosphorus upto 50 kg P2O5 ha-1 showed progressive and significantly increased N uptake and P, K, S, Fe, Zn, Cu and Mn uptake by plant in which registered significant up to 40 kg P2O5 ha-1 at flowering stage of mustard. A significant increase in nutrient content N and P in seed and N in straw was recorded up to 50 kg P2O5 ha-1 and K, S, Fe and Mn content in seed and P, K, S, Fe and Mn was significantly recorded up to application 40 kg P2O5 ha-1 except Zn and Cu content in seed and straw. Application of phosphorus upto 50 kg P2O5 ha-1 showed progressive and significantly increased N and P uptake by seed and straw and K, S, Fe, Zn, Cu and Mn uptake by seed and straw in which registered significant up to 40 kg P2O5 ha-1 at harvest of mustard. Similarly, significantly higher uptake of total N and P by mustard with significantly higher nutrient status of soil after crop harvest due to progressively application P upto 50 kg P2O5 ha-1 in respect to available N, P, K, S, and upto 40 kg P2O5 ha-1 in respect to available Fe. and Mn except Zn and Cu. Net returns to the tune of ` 38531 ha-1 were realized with 50 kg P2O5 ha-1 which accounts 18.22, 44.31 and 46.64 per cent higher over control, 30 and 40 kg P2O5 ha-1, respectively. The mean maximum B:C (1.84) was recorded with 40 kg ha-1 which account 30.06 and 18.47 per cent higher over control, and 30 kg P2O5 ha-1, respectively. The sulphur nutrition recorded significantly higher plant height plant-1 at 60 DAS and at harvest stage with progressive application of sulphur up to 40 kg S ha-1 to the tune of 10.16 and 4.27 per cent at 60 DAS and 4.48 and 3.46 per cent increased at harvest stage over control and 30 kg S ha-1. Application of 40 kg S ha-1 produced significantly higher dry matter accumulation plant-1 at 30, 60, 90 DAS and harvest stage on pooled basis (1.00, 24.37, 54.54 and 68.85 g plant-1, respectively). Application of 40 kg S ha-1 recorded significantly higher number of branches plant -1, number of siliquae plant-1, number of seed siliqua-1 and test weight (23.73, 364.96, 15.86 and 5.67 g, respectively), which represent 18.00, 7.21, 6.16 and 6.98 per cent increase over control. Similarly, significantly higher seed, straw and biological yield were produced due to 40 kg S ha-1 which represented 23.91, 18.20 and 19.80 per cent enhancement over control (15.14, 39.78 and 27.95 q ha-1, respectively). Application of sulphur also proved beneficial in increasing significantly higher oil and protein content (39.68 and 20.40 %), oil and protein yield (770.29 and 399.21 kg ha-1). Application of sulphur upto 40 kg S ha-1 showed progressive and significantly increased N, Zn, Fe and Mn content and P, K, S and Cu in which registered in plant of mustard at flowering stage significant upto 50 kg S ha-1. Application of sulphur upto 50 kg S ha-1 showed progressive and significantly increased uptake of N, P, K, S, Fe, Zn, Cu and Mn by plant at flowering stage of mustard. Application of S upto 40 kg ha-1 resulted significantly increased N, P, Fe, Zn, Cu and Mn content in seed and N, P, K, Fe, Zn, Cu and Mn content in straw and K and S in seed and S in straw significantly increase up to application of sulphur up to 50 kg S ha-1 over all preceding sulphur levels. Application of sulphur upto 50 kg S ha-1 showed progressive and significantly increased N, P, K, S, Fe, Zn, Cu and Mn uptake by seed and P, S and Cu uptake by straw and N, K, Fe, Zn and Mn uptake by straw in which registered significant up to 40 kg S ha-1 at harvest of mustard during on pooled basis. Similarly, significantly higher uptake of total N, P, K, S, Zn, Fe, Cu and Mn by mustard with increasing levels of sulphur upto 50 kg S ha-1. Significantly higher nutrient status of soil after crop harvest due to progressively application upto 50 kg S ha-1 in respect to available P, S, Fe, Zn, Cu and Mn. Application of 40 kg S ha-1 significantly increased in respect to available N and K in soil after harvest of mustard crop. Net returns to the tune of `ha-1 38172 were realized with 50 kg S ha-1 which accounts 25.60, 38.77 and 45.46 per cent increased over control, 30 and 40 kg S ha-1, respectively. The mean maximum B: C (1.89) was recorded with 50 kg S ha-1 which accounts 22.22, 30.07 and 40.00 per cent increase over control, 30 kg S ha-1 and 40 kg S ha-1 respectively. Seed inoculation with PSB significantly increase in plant height plant-1, number of branches plant-1, dry matter accumulation plant-1, number of siliquae plant-1, number of seed siliqua-1, test weight (g), seed, straw, biological yield, oil and protein content and yield over control. Inoculation of seed with PSB showed progressive and significantly increased N, P, K, S, Fe and Mn content in plant at flowering stage, seed and straw except Zn and Cu content. Inoculation of seed also improved uptake of all nutrients at flowering stage, seed and straw of mustard and total uptake of mustard significantly increase over control. Application of seed inoculation with PSB proved beneficial increased the post harvest availability of nutrients N, P, K, S, Fe and Mn in soil except Zn and Cu, respectively. Seed inoculation with PSB fetched an additional net return of (` 2691 ha-1). The maximum B:C (2.08) was recorded with seed inoculation with PSB than no inoculation. The highest monetary returns of mustard was obtained with 50 kg P2O5 ha-1 + 50 kg S ha-1 along with seed inoculation (PSB). This treatment gave seed and straw yield of mustard with monetary return (` 45718 ha-1) with B:C (2.10) as compared to ` 18371 ha-1 and B:C of 1.03 over control.
