A field experiment was conducted during Rabi season of 2015–16 at the Instructional cum Research Farm, IGKV, Raipur to study the fibre productivity, seed quality and profitability of linseed crop under different irrigation scheduling and nitrogen levels. The experiment was laid out in split plot design keeping four irrigation scheduling viz., come-up (I1), one (I2), two (I3) and three irrigation (I4) in main plots and four levels of nitrogen viz., control (N0), 30 kg (N1), 60 kg (N2) and 90 kg N ha−1 (N3) in sub plots with three replications. Results revealed that the application of two (I3) and three irrigations (I4) were equally effective; and application of 90 kg N ha−1 (N3) exhibited superior in terms of fibre, seed, oil and protein yield as well as higher gross return, net income and B:C ratio. With respect to interaction between irrigation scheduling and levels of nitrogen, two irrigations × 90 kg N ha−1 (I3 × N3) gave highest fibre (699 kg ha−1) and seed yield with highest net income and B:C ratio (3.53).
