A field experiment was carried out in blackgram to find out the effect of various weed management practices and different establishment methods on growth, weed density, weed dry matter, yield and yield attributes at N. E. Bourlag crop research center of G.B.P.U.A&T, Pantnagar during kharif season of 2016. Field experiment was consisted of 2 main plot treatment i.e. raised bed and flat bed and 4 sub-plot treatment i.e. weedy check, Pre emergence (PE) application of pendimethalin 30EC @1.0 Kg/ha, post emergence (PoE) application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS and PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS applied as which was carried out under a split plot design. Growth parameters, yield, yield attributes, weed density and weed dry matter was not affected significantly by different establishment methods except number of pods per plant, although raised bed method produced better result than flatbed method. Significantly, higher yield attributes and grain yield per hectare was obtained due to different weed management practices. Pendimethalin @1.0kg/ha 30 EC as PE, imazethapyr @0.055 kg/ha 10SL at 20 DAS as PoE, PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS produced significantly higher productivity by 133.7 and 100.4 and 221% over weedy check respectively. Lowest weed density and weed dry matter was recorded under PE application of pendimethalin 30EC @1.0 Kg/ha + PoE application of imazethapyr 10 SL @ 0.055 kg/ha applied at 20DAS.
