A field experiment was conducted during rabi season of 2017-18 at Central Research Farm, Gayespur, Nadia, under Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal to assess the performance of hybrid mustard as influenced by irrigation and nitrogen levels. The experiment comprised of 9 treatment combination in split plot design with three replications. The result of experiment revealed that the growth and yield of hybrid mustard was significantly influenced by irrigation and nitrogen management in low land rice ecosystem. The maximum plant height and crop growth rate was noticed with IW/CPE=1.2 and 120 kg N/ha and the lowest was recorded under IW/CPE=0.8 and 40 kg N/ha. The highest value of dry matter accumulation was registered with IW/CPE=1.0 and 120 kg N/ha and the lowest was recorded under IW/CPE= 1.0 and 80 kg N/ha. The maximum number of branches was recorded under IW/CPE=1.2 and the minimum was observed with IW/CPE=0.8. Among the nitrogen levels, number of branches was found the highest with 120 kg N/ha and the lowest was recorded with 40 kg N/ha. The maximum number of siliqua per plant was noticed under IW/CPE=1.2 and the lowest was recorded with IW/CPE= 1.0 and 40 kg N/ha. The number of seeds per siliqua was found the highest with IW/CPE=1.2 and the lowest was obtained with IW/CPE=0.8. The maximum test weight was noticed with IW/CPE=1.0 and 120 kg N/ha and the lowest was recorded under IW/CPE=0.8 and 40 kg N/ha. The maximum seed yield was achieved in IW/CPE=1.0 with 120 kg nitrogen/ha and the minimum was noted with IW/CPE=1.2 with 40 kg N/ha. The maximum biological yield was registered in IW/CPE=0.8 with 120 kg nitrogen/ha and the lowest was recorded with IW/CPE=1.2 with 40 kg nitrogen/ha.
