Abstract:

A field experiment was conducted at Agricultural Research Institute, Main Farm, Professor Jayashankar Telangana State Agriculture University, Rajendranagar, Hyderabad, India during Rabi (winter season) 2020 to evaluate the efficacy of herbicides in chickpea (Cicer arietinum L.) variety ‘JG-11’. The experiment was conducted in RBD with three replications. The application of pendimethalin 30% EC + imazethapyr 2% EC (ready mix [RM]) 1.0 kg/ha as pre-emergence application (PE) followed by (fb) mechanical weeding at 30 days after seeding (DAS) recorded lowest weed density and biomass at 20 and 40 DAS. Pendimethalin 1.0 kg/ha PE fb mechanical weeding at 20 and 40 DAS, oxyfluorfen 140 g/ha PE fb mechanical weeding at 20 and 40 DAS, pendimethalin + imazethapyr (RM) 1.0 kg/ha PE fb mechanical weeding at 30 DAS registered 1.95, 1.94 and 2.08 t/ha seed yield, respectively as against seed yield of 1.11 t/ha in weedy check. The maximum net returns of  72093/ha were recorded in pendimethalin + imazethapyr (RM) 1.0 kg/ha PE fb mechanical weeding at 30 DAS with B-C ratio of 3.27, which was closely followed by oxyfluorfen 140 g/ha PE fb mechanical weeding at 20 and 40 DAS with net returns of  64980/ha and B:C ratio of 2.99.
