Effect of Row Spacing and Zinc on Growth and Yield of Mustard (Brassica juncea L.)

The field Study was conducted during Rabi season of 2021 at experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj and Uttar Pradesh, India to determine the “Effect of row spacing and zinc on growth and yield of Mustard (Brassica juncea L.)”. This experiment embodied of 3 row spacings 20 cm, 30 cm, 40 cm and 3 levels of zinc fertilizer of 5 kg/ha, 10 kg/ha and 15 kg/ha. The experiment was layed out in statistical design of Randomized Block Design (RBD) with three replications. Full doses of Nitrogen, Phosphorus and Potassium fertilizers were applied as basal. The used variety was Varuna T-59. Report of the study indicates that, among different row spacings and zinc the treatment with row spacing 40 cm and zinc at 15 kg/ha produced significantly highest plant height (202.36 cm), higher number of branches (11.18), dry weight/plant (32.96g). The treatment combination with row spacing 30 cm and zinc 15 kg/ha produces the highest number of siliquae per plant (295.65), number of seeds per siliqua (15.47), test weight (3.87 g), seed yield (2.10 t/ha), stover yield (4.53 t/ha), and Harvest index (31.66%). However, the treatment with row spacing 30 cm and zinc at 15 kg/ha was found to be effective in highest gross return (126420 INR/ha), net return (89638.4 INR/ha) and benefit cost ratio (2.43) when compared to the other treatments.
