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 effect of irrigation and nitrogen levels on performance of hybrid mustard. The experiment was comprised of nine treatment combinations in split plot design with replicated thrice. The results revealed that, maximum seed yield (2016 kg/ha) was achieved in IW/CPE=1.0 with 120 kg nitrogen/ha followed by IW/CPE=1.2 with the same dose of nitrogen/ha. The highest value of oil percentage (40.2%) was noticed in IW/CPE=1.2 with application of 80 kg N/ha followed by IW/CPE=1.0 and same dose of nitrogen. The maximum oil yield (721 litre/ha) was registered in IW/CPE=1.2 with 120 kg N/ha followed by IW/CPE=1.0 with the same dose of nitrogen/ha. The maximum NUE (30.0 %) was achieved in IW/CPE=1.0 with 40 kg N/ha followed by IW/CPE=1.0 and with 40 kg N/ha. Among the irrigation levels, maximum WUE was recorded 9.6 kg/ha/mm with IW/CPE=1.0 whereas, application of 120 kg N/ha was noticed maximum WUE about 11.2 kg/ha/mm. The maximum biological yield was registerd 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. The IW/CPE=1.0 along with 120 kg nitrogen/ha is a suitable combination for profitable production of hybrid mustard in the Mohanpur, West Bengal and other similar ecoregions.
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 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 nitrogen @ 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.
