The experiments were conducted to standardize of pressurized irrigation systems (micro-irrigation) and fertilization for mustard (Brassica junecea I. Czernj and Cosson) crop during rabi season of 2009–10 and 2010–11. Five irrigation systems in main plot viz. micro-sprinkler system (MS), MS followed by check basin (CB), drip irrigation system (DS), DS followed by CD and (CB) alone were studied in split plot design. Four nitrogen doses 0, 40, 80 and 120 kg/ha were taken in the subplots. MS, DS significantly incresed dry weight, chlorophyll concentration, primary and secondary branches, main shoot length, total siliquae and 1000 seed weight and seed yield as compared to CB. Higher sustainability yield index, enhanced water use efficiency, production efficiency, seed and protein yield were recorded in MS and DS. Among fertigation, 120 kg N/ha was found superior in enhancing the oil and seed yield, water use efficiency and production efficiency but overall the effect of 80 Kg N fertigation was on par with 120 Kg N/ha for some of the growth and yield parameters and biological, seed, oil and protein yield. Thus micro irrigation saves water in addition to enhancement of mustard productivity.
