The bacterium to plant signal, lipo-chito-oligosaccharides (LCOs) or Nod factors induce cell division and enhance plant growth. In the present study LCO has been applied through foliar spray at two different stages (V 2 ), 20-25 DAS and 40-45 DAS (V 4 ). All the yield contributing parameters were increased by the foliar spray of LCO in soybean and the maximum yield was recorded in LCO @ 300 ml ha -1 at 20-25 DAS. The yield increased by 10.6 per cent at kharif and 14.3 per cent during rabi 2012. Correlation studies indicated that seed yield per hectare exhibited stable positive association vis-a vis number of flowers, pods per plant, fertility co- efficient, 100 grains weight and harvest index at different stages and seasons
