The field experiment entitled "Growth and yield of hybrid mustard as influenced by irrigation scheduling and nitrogen management" was conducted at the Central Research Farm, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal during rabi season (2017-18) in alluvial soil having medium soil fertility. It was conducted in split-plot design with three replications comprising 3-main plot irrigation scheduling treatments based in IW/CPE = 0.8, 1.0 & 1.2; and three sub-plot treatments of

... gen @ 40, 80 & 120 kg/ha. The result of experiment revealed that the growth and yield of hybrid mustard crop was significantly influenced by both the main and sub-plot treatments. The maximum growth parameter like plant height, dry matter accumulation, CGR of hybrid mustard crop were recorded with IW/CPE=1.2 irrigation level and 120 kg N/ha. The yield attributes and yield also followed the similar trend, maximum yield was obtaied with application of 120 kg N/h under irrigation regime scheduled at IW/CPE=1.2. The yield variation due to irrigation regimes and nitrogen management was to the tune of 13.35 to 17.14% and 44.19 to 83.09%, respectively.
