Abstract: A field experiment was conducted at BCKV farm, West Bengal during rabi 2010-12 to evaluate the effect of irrigation and mulch on growth and productivity of linseed (Linum usitatissimum). Irrigation at IW/CPE of 0.6 showed 6.72 and 17.63% higher seed yield compared to IW/CPE of 0.4 and rainfed. Treatment receiving black polythene mulch registered about 4.33, 8.72 and 14.76% higher seed yield over straw @ 5 t ha^-1, water hyacinth @ 5t ha^-1 and no mulch. Water use efficiency was highest with rainfed treatment receiving black polythene. Combining irrigation at IW/CPE of 0.6 and black polythene led to the maximization of net return and B:C ratio and proved as best.
