Field experiments were conducted at farmer's fields in Hoshangabad district of Madhya Pradesh during khari 2010 to 2011 to assess economic feasibility of mole drain for soybean crop. The mole drain spacing selected includes 2, 4, 6 and 8 m and these drains were formed at an average depth of 0.4, 0.5 and 0.6 m from ground surface. Under various treatment combinations, the seed yield was recorded highest under S1D1(mole drains at the spacing of 2 m on the depth of 0.4 m) followed by S1D2 (2m spacing x 0.5 m depth) which was recorded higher by 93.7 and 92.9 per cent to that of under, S0D0: Control, respectively. Net return and B:C ratio of mole drain with S2D1 (spacing of 4 m at the depth 0.4 m) & S1D1 (spacing of 2 m at the depth 0.4 m) were found most profitable during 1st year and 2nd year of experiment respectively. Effect of mole drainage on the yield & economic of soybean under waterlogged conditions was found better.
