Abstract
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).
