Abstract: The experiment was carried out at agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (Uttar Pradesh) India, during the kharif season 2011 - 12. The experiment was laid out in randomized block design having ten treatments i.e. (Fluchloralin @ 1kg a.i ha-1 PPI, Fluchloralin @ 1kg a.i ha-1 as PPI + one hand weeding at (30DAS), Anilophos @ 1 kg a.i ha-1 as PE, Anilophos @1 kg a.i ha-1 as PE one hand weeding at (30 DAS). Pendimethalin @ 1 kg a.i ha-1 as PE, Pendimethalin @ 1 kg a.i. ha-1 as PE + one hand weeding at (30 DAS), one hand weeding at (25 DAS), two hand weeding (25 and 45 DAS), weedy check and weed free check. All the treatments were replicated three times. Among the weed management practices integrated approach i.e pre-emergence application of Pendimethalin @ 1kg a.i ha-1 + one hand weeding at 30 DAS has been found promising to reduce the weed density as well as weed dry weight. Pre-emergence application of Pendimethalin @ 1 kg a.i. ha-1 + one hand weeding at (30 DAS) proved its superiority over other methods of weed control in respect of all the growth and development characters of pigeon pea crop, which was comparable with weed free check.
