Abstract:
A field research trial was conducted to study “Effect of phosphorus and sulphur levels on growth and yield of Yellow Mustard (Brassica campestris L.)” at Crop Research Farm, Naini Agriculture Institute, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during the period of Rabi season of 2020-21. The experiment was carried out in a randomized block design comprising of nine treatments of three levels of phosphorus (40,50 and 60 kg P₂O₅/ha) and sulphur (30,40 and 50 kg S/ha) which were replicated three times. The nutrients phosphorus and sulphur were applied through DAP and gypsum. The result revealed that growth and yield attributes of yellow mustard ware increased through successive increases in phosphorus and sulphur levels. The application of 60 kg phosphorus/ha + 50 kg sulphur/ha reported significantly maximum plant height (120.79 cm), number of branches per plant (8.67), dry matter accumulations (19.39 g), crop growth rate (13.92 g/m²/day), relative growth rate (0.052 g/g/day), siliqua per plant (94.67), seed per siliqua (43.33), test weight (3.87 g), seed yield (1893.33 kg/ha) and stover yield (4323.33 kg/ha) and also found highest gross return (₹126853.11/ha), net return (₹66396.11/ha) and benefit: cost ratio (1.09) respectively.
