Field experiments were conducted during kharif 2010 to 2011 for sustaining productivity of soybean through mole drainage technology in temporary waterlogged vertisols at farmer’s fields in Hoshangabad district of Madhya Pradesh.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 a split plot designed experiment with 3 replications.Under various treatment combinations, the plant height, number of branches per plant, root nodules per plant, dry weight of root nodules per plant and yield of soybean crop are highest in 2 m drain spacing followed by 4m, 6m, 8m and control plot in all selected depths.The highest B: C ratio was recorded under S₂D₁ followed by S₃D₁, while the lowest net return was recorded under S₄D₃ in the year 2010-11. In 2011-12 and in pooled data analysis the B:C ratio was recorded higher under S₁D₁ followed by S₁D₂  respectively. The lowest B: C ratio under mole drain treatment was found under control plot.Pipe less drainage (mole) technology for vertisols of Madhya Pradesh is found better in view of soybean productivity.
