Abstract: A field experiment was conducted to study the effect of levels of irrigation and mulch on growth attributes, yield attributes, yields, water use and water use efficiency of rapeseed during rabi season of 2014-15 at Regional Research Station, Gayeshpur, Nadia, West Bengal. The experiment was conducted with 12 treatment combinations (4 Irrigation levels considered as main plot and 3 levels of mulch as sub plot) in a split plot design replicated thrice. The study revealed that both irrigation and mulch levels significantly influenced growth attributes, yield attributes, seed yield and oil yield. Highest value were exhibited when irrigation applied at 1W:CPE ratio of 1.0 in combination with full row straw mulching. The highest total water use (388.78mm) and minimum WUE (3.06 kgha-1 mm-1) and the lowest total water use (89.57mm) and maximum WUE (6.31 kg ha-1mm-1) were recorded under I4M1 and I1 Mo treatment combination respectively.
