A field experiment was conducted in the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj, a field experiment was carried out during the Rabi season of 2024. to ascertain "The Impact of Zinc and Nitrogen on Mustard (Brassica juncea L.) Growth and Yield." Sandy loam in texture, the experimental field soil had a moderately basic reaction (p H 7.2), a medium organic carbon (0.49%) medium in available nitrogen (225.5 kg/ha), and very high levels of available potassium (233.4 kg/ha) and accessible phosphorus (18.6 kg/ha). Three levels of Zinc (4, 6 and 8 kg/ha) and Nitrogen (70, 80 and 90 kg/ha) along with recommended dose of fertilizers ((80:40:40 kg NPK/ha). Three replications and a two-factor Randomized Block Design (RBD) were used to set up the experiment. The outcome demonstrated that treatment 9 had noticeably greater growth characteristics, including plant height (144.93 cm), dry weight (28.93 g/plant), and number of branches/plant (19.01). In contrast, the treatment's test weight (5.78), number of siliqua/plant (209), number of seeds/p siliqua (19), yield qualities, and grain yield (3.5 t/ha) and stover yield (6.05 t/ha) were noted. These findings imply that the growth and yield of mustard were enhanced by the combination of 90 kg N/ha and 8 kg Zn/ha.
