Online published on 20 November, 2023. Abstract A field experiment was conducted during 2020-21 and 2021-22 to study the effect of different post-emergence (POE) herbicides for broad spectrum weed management in chickpea. The experiment was laid out in a randomized block design with eight treatments and replicated thrice. Treatments comprises topramezone 20.6 g a.i. ha-1 at 14 DAS, topramezone 20.6 g a.i. ha-1 at 21 DAS, topramezone 25.7 g a.i. ha-1 at 14 DAS, topramezone 25.7 g a.i. ha-1 at 21 DAS, quizalofop-p-ethyl 100 g a.i. ha-1 at 21 DAS, unweeded control, weed free check (manual) and imazethapyr + manual weed control (MWC). Among the different herbicidal treatments, topramezone 20.6 g a.i. ha-1 at 21 DAS significantly higher seed yield (1377 kg ha-1) followed by topramezone 20.6 g a.i. ha-1 at 21 DAS (1265 kg ha-1), highest weed control efficiency and also recorded higher return (. 45,659 ha-1 ) and B: C ratio (2.73) during 2020-21.
