Field experiments were conducted to study the effect Zinc and Sulphur on growth parameters, yield components and yield of Mustard during rabi season of 2021-22 at students instructional farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The experiment consist of 14 treatments combinations in factorial randomized block design with three replications consisted of 7 fertility levels (including sulphur and zinc) and two variatal factors (i.e. Rohini & Maya). Mustard varieties Rohini & Maya were grown with the recommended agronomic practices. On the basis of results emanated from investigation it can be concluded that among the growth parameters maximum plant height at harvest is 160.6 cm and 161.2 cm, maximum number of primary branches is 8.5 and 8.3 and secondary branches is 14.4 and 14.8 during both the years of experimentation are associated with the treatment T14[Var. Maya with Sulphur @900 ppm]. Similarly, among the yield components and productivity parameters maximum number of siliquae per plant, number of seed siliqua-1, 1000 test wt. (gm), grain yield (q ha-1), stover yield (q ha-1) was also found in the treatment T14 [Var. Maya with Sulphur @900 ppm] followed by treatment T11 [Var. Maya with ZnSo4 @1500] and treatment T7 [Var. Rohini with Sulphur @1500].
