A field experiment was undertaken at PAU, Regional Station (Bathinda) to evaluate the effect of weed management practices on the performance of cluster bean [(Cyamopsis tetragonoloba (L.) Taub] under AICRP on Arid Legumes during the kharif season of 2015 and 2016. Data revealed that weed dry matter was lowest in case of weed free check (T₈) as plots were kept weed free as per the treatment. Among other treatment combinations Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr+ Imazamox @ 40g a.i./ha at 2–3 leaf stage of weeds (T₇) produced the lowest weed dry matter closely followed by Pendimethalin @ 0.75 kg a.i./ha as PE+ One Intercultivation at 20–25 DAS (T₆) and Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr @ 40g a.i./ha at 2–3 leaf stage of weeds (T₅). WCE was highest in weed free followed by Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr+ Imazamox @ 40g a.i./ha at 2–3 leaf stage of weeds (T₇). Highest seed yield was recorded in weed free check followed by Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr @ 40g a.i./ha at 2–3 leaf stage of weeds (T₅), Pendimethalin @ 0.75 kg a.i./ha + One Intercultivation at 20–25DAS (T₆) and Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr+ Imazamox @ 40g a.i./ha at 2–3 leaf stage of weeds (T₇).
