A field study was carried out at Vegetable Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during rabi season of the year 2012-2013 to standardize the drip irrigation levels and plastics mulching on growth, maturity, yield, water-use efficiency and economics of broccoli. Seven irrigation levels based on pan evaporation (Epan) from a USWB Class-A open pan i.e. 100%, 80% and 60 % of PE replenishment daily as well as alternate day along with surface irrigation was tested under two levels of mulching viz., without mulch (open surface)and UV stabilised 50-micron thick black plastic mulch in a two factorial Randomized Block Design replicated thrice. All growth characters, as well as yield and yield attributes, were found significantly higher with 100 % PE replenishment daily under plastic mulch. The highest water use efficiency (WUE) of 13.92 q ha^-1 cm^-1 was observed with 60 % PE replenishment daily through drip under plastics mulch and lowest (6.02 q ha^-1 cm^-1) with traditional practices i.e., surface irrigation under without mulched (open surface) condition. Highest gross return (Rs.300795ha^-1), net return (Rs.214969 ha^-1) and benefit-cost: ratio of 1: 3.50 was obtained in100 % PE replenishment daily with the combination of black plastic mulching.
