A field experiment was conducted at Agriculture Research Station, Badnapur on a clayey soil during kharif season of 2016-17 to find out the effect of with two factors viz., spacing (three levels: S1-120 cm x 30 cm spacing, S2-120 cm x 45 cm spacing, S3-120 cm x 60 cm) and four irrigation levels (irrigation at 50% Epan through drip (I1), irrigation at 75% Epan through drip (I2), irrigation at, 100% Epan through drip (I3), supplemental irrigation at 50% flowering through furrows (I4) with 12 treatments combinations. Each experimental unit was repeated three times. The size of gross plot 9.60 X 3.60 m2 and in net plot 7.20 m x 2.40 m for 90 x 30 and 30 x 60 cm, 7.20 m x 2.70 m for 90 x 45 cm spacing. Sowing was completed on 2nd July 2016. The fertilizer dose of 25:50:00 NPK kg ha-1 was applied after sowing. Amongst, spacing 120x45 cm spacing recorded maximum seed yield (2391 kg ha-1) and net monitory returns (84565 kg ha-1) than wider spacing 120 x 30 cm and 120 x 60 cm, respectively. Amongst irrigation levels, irrigation at 75% Epan through drip recorded maximum seed yield (2674 kg ha-1) and NMR (96995 Rs ha-1) followed by irrigation at 100% Epan through drip, irrigation at 50% Epan through drip and irrigation at 50% flowering through furrows, respectively. Highest water use efficiency was observed under irrigation at 50% flowering through furrows (32.15 kg ha-1 mm-1) followed by irrigation at 50% Epan through drip (7.76 kg ha-1 mm-1), irrigation at 75% Epan through drip (6.98 kg ha-1 mm-1) and irrigation at 100% Epan through drip (4.30 kg ha-1 mm-1).
