A field experiment was carried out at the Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Rabi season 2022 on Mustard crop. The experiment was laid out in randomized block design with ten treatments and three replications. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The maximum plant height (175.97 cm), primary branches (8.85), secondary branches (18.85/plant), plant dry weight (40.97 g/plant) at 100 DAS in hybrid M-155 was recorded. Maximum Crop growth rate (CGR) recorded at 60-80 DAS (10.24 g/m2 /day), number of siliqua/plant (466.27), number of seeds/siliqua (13.63), test weight (5.40 g) and seed yield (2.40 t/ha) were observed in hybrid M-155. In terms of economics, highest gross returns (Rs 130905.7/ha), net returns (Rs 81592.73/ha) and B:C ratio (1.65) were observed in hybrid M-155.
