Subscribe/Renew Journal
Effect of mole drain spacings and depths on the growth character of soybean was studied in the farmer's fields in Hoshangabad district of Madhya Pradesh. Mole drains were formed with a mole plough with a 75 mm bullet or expander diameter using a 75 hp wheeled tractor. The drains were formed at 2 m, 4 m, 6 m and 8 m spacing at an average depth of 0.4 m, 0.5 m and 0.6 m from ground surface. The average length of each lateral was 50 m and the tractor was operated with a speed of 0.80 kmph. The plant height, number of branches per plant, dry matter accumulation per plant and yield of soybean crop were highest in 2 m drain spacing followed by 4m, 6m, 8m and control plot in all selected depths.
