A field experiment was conducted during two consecutive (Rabi) winter seasons (2018-19 and 2019-20) at Agricultural Research Station, Navgaon (Alwar), S.K.N. Agriculture University, Jobner, Jaipur (Rajasthan), India, to study the effect of weed management practices in chickpea. The experiment was laid out in a randomized block design with eight treatments and replicated thrice. The crop was sown as per the package of practices recommended for zone IIIB of Rajasthan. Treatments included application of pendimethalin 30% EC 1.0 kg/ha as pre-emergence, and quizalofop-p-ethyl 10% SL at 50g/ha, fenoxaprop p-butyl 10% EC at 100 g/ha, imazethapyr 10% EC at 75 g/ha, imazethapyr (35%) + imazamox (35%) at 100 g/ha, imazethapyr (2%) + pendimethalin (30%) at 2.5 litre/ha as post-emergence along with weedy and weed free checks. Among the different herbicidal treatments, imazethapyr (35%) + imazamox (35%) at 100 g/ha recorded significantly higher seed yield 2.22 t/ha in 2018-19 and 2.28 t/ha in 2019-20 with higher weed control efficiency and the lowest weed index. However, it remained at par with imazethapyr 10% EC 75 g/ha and, imazethapyr (2%) + pendimethalin (30%) at 1.0 kg/ha.
