A field experiment was carried out during kharif seasons of 2006 and 2007, to study the effect of age of seedlings, weed management practices and humic acid application on System of Rice Intensification. Transplanting 14 days old seedlings with pre emergence application of Pretilachlor at the rate of 0.75 kg ai/ha and one mechanical weeding at 30 DAT and humic acid application as seedling dip (0.3%) and foliar spray twice significantly reduced weed growth and improved growth parameters, yield attributes and yield of rice.
