INFLUENCE OF MOLE DRAIN SPACING AND DEPTH ON YIELD ATTRIBUTES AND YIELD OF SOYBEAN (GLYCINE MAX L.)S.S. Dhakad, K.V. Ramana Rao and K.P. Mishra
Field experiments were conducted in Hoshangabad district of Madhya Pradesh during 2010 and 2011 to assess the effect of mole drain spacing and depths on yield attributes and yield of soybean in temporarily waterlogged Vertisols. The experiments were conducted in a split plot design with 3 replications. The selected mole drain spacings include 2, 4, 6 and 8 m with average mole drain depth of 0.4, 0.5 and 0.6 m from ground surface. Mole drain with spacing of 2 m at the depth 0.4 m was found better in term of plant population, number of pods per plant, pod length, number of seeds per pod, seed index and yield comparison with other spacing and depth as well as the control. The highest yield was recorded under S1D1 followed by S1D2 in pooled data analysis for soybean.
